System Overview

WaveCAST EIGHT D is the new, multi-channel Wi-Fi assistive listening platform designed for larger assistive listening applications. The WaveCAST EIGHT D is designed for pro-audio applications where high-quality sound is required for streaming multi-channel audio in real time to smartphones and/or tablets. It is built on a hardware-based DSP audio system architecture, allowing system optimization to achieve the highest quality experience for the particular audio stream being delivered.
Note that these instructions only apply to the WaveCAST EIGHT D and do not apply to other WaveCAST systems, including the non-Dante enabled WaveCAST EIGHT.

*If Dante™ Audio is to be physically isolated from the LAN, a separate NETWORK ROUTER and/or SWITCH may be required. The LAN router may also be conﬁgured to keep Dante™ Audio separated from the LAN with port management or other techniques, but as Dante traffc increases, LAN performance may decrease.

Quick Setup Instructions

Place the WaveCAST EIGHT transmitter where it will be stored safely, such as in an server rack. We do not recommend wall or ceiling mounting, or putting the device on a cart.
Connect the Dante source to the Dante port on the back of the device. The Dante source will need to be routed to the WaveCAST EIGHT D using Dante Controller, Dante Via or similar Dante equipment.
Connect the power supply to the Power Supply connector located on the back of the WaveCAST EIGHT D.
Connect an Ethernet cable from your local area network, or Wi-Fi router to the connector on the transmitter labelled Ethernet. This network will be used to broadcast the audio.
Push the power button to turn the unit on. If the unit does not turn on, check your power connections.
Once the transmitter is on and detects an active network is present, the WaveCAST EIGHT D’s IP address will be displayed at the top of the main screen.
Open a web browser on a computer or mobile device that is also connected to the same local network as the WaveCAST EIGHT D. In the address bar of the browser, type in the IP address that is shown on the front of the transmitter’s main info screen, and push the enter key on the keyboard. (Note: it is not necessary to type “http://” or “www.” preceding the IP address, just the characters following “IP:”, including the periods. For example: 192.168.1.123)
The browser will open the transmitter’s web page, displaying a Login button. Click the log-in button and enter the user name “admin” and the default password “admin”.
The web browser will now show the transmitter’s Main Settings tab, which shows the current WaveCAST EIGHT D status info. The tabs at the top navigate to different pages that allow adjustment of the settings. The channel to adjust can be selected from the drop down menu at the top right.
Adjust any of the server settings, such as the server name, if desired. For each channel:
If the channel should be disabled, go to the options page. Uncheck the ‘channel enabled’ box and click submit. Channels are enabled by default, and will show up on the WaveCAST App. Disabled channels will not show on the app.
On the main settings page, adjust the audio gain, set the audio source to Dante, and adjust the audio preset for each channel that will be used. Click submit when finished.
Adjust any other channel specific settings as needed.
Use a personal device with the WaveCAST App installed to listen to the audio and test that device is working and sounds correct.

Router and Network Equipment Selection

The WaveCAST EIGHT D is intended to be set up on an already existing Wi-Fi network; however, upgrades to your network equipment may be necessary depending on the performance desired from the WaveCAST EIGHT D. For instance, a higher-end, more powerful router will allow more users to connect to your audio stream than using a cheaper, less powerful router.
The Wi-Fi network will need to be accessible to the users who will be listening to the audio. A public or Guest Wi-Fi network will usually be ideal for ease of accessibility. If the user’s devices cannot connect to the network due to security settings, they will not be able to hear the audio.
The WaveCAST EIGHT D system will put a demand on the network. If the network cannot handle the demand, whether because it is being used for other networking needs or because the networking hardware is not strong enough, the WaveCAST EIGHT D will be unable to reach its maximum audience.
When streaming to a small or medium sized audience, a basic networking configuration may suffice. When streaming music using multiple channels (such as having several WaveCAST EIGHT D units on your network), a powerful router and network configuration is more likely to be required.
The WaveCAST Networking Guide is available on the Williams AV website for additional networking tips. The WaveCAST networking guide applies to the FM + as well as other WaveCAST products.

Network and Power Connections

Power Supply Connection
Connect the power supply to the Power Supply Jack located on the rear of the WaveCAST EIGHT D server.
Dante Connection
Connect a Dante controller to the Dante port. Connect any Dante devices to your Dante controller.
Network Connection
The Ethernet port must be used to connect the WaveCAST EIGHT D to local network. A network connection is required to use any features of the WaveCAST EIGHT D.
An Ethernet connection will not allow the WI-Fi broadcast features to work; a Wi-Fi connection must be available on the network.
Once a connection has been established, an IP address will automatically be assigned to the WaveCAST EIGHT D (see the front panel section’s “Main Menu” on page 14 for help finding the IP Address). Device settings can then be set via the web interface, including changing any network settings.
NOTE: Most settings need to be set BEFORE connecting audio sources.

System Settings

Most settings are adjusted via the web interface by using a computer (see “Web Control Interface” on page 9). A handful of settings can be adjusted via the front panel display (see “Front Panel Interface” on page 14).
Network Configuration
Network Settings can only be edited from the web interface. An IP address will be automatically assigned to the WaveCAST EIGHT D once an Ethernet cable has been connected to the device and network connection found. Additional configuration would need to be made through the web interface.
Adjusting Network Settings
The Network Settings screen where the IP Address Mode (Static or DHCP), the IP Address, and Subnet Mask are set via the web interface. See “Server Settings Page” on page 12 for details on how to use the web interface.
IP Address Mode Static or DHCP
IP Address If the IP Address Mode is set to Static, this is where the IP Address is manually entered
Subnet Mask If the IP Address Mode is set to Static, this is where the Subnet Mask is manually entered
Gateway If the IP Address Mode is set to Static, this is where the gateway is manually entered
Multicast Address If needed, the multicast cast address can be enabled and either manually set. If not manually set, a preset fixed address will be assigned by the WaveCAST EIGHT D. This setting is under the Options menu and is set per channel.
DHCP IP Addresses are automatically created, and are usually preferred to a manual static IP address.
To set up a static IP Address:

Determine an appropriate static IP address for the WaveCAST EIGHT D.
a. If someone set up your network, they may be able to help you determine an appropriate IP address (i.e. network system administrator).
b. There should be no other device having this same address on the network.
c. This will be an address on the same subnet as the router.
For example, if the router’s address is 192.168.1.100, the first three sets of numbers will be the same (i.e. 192.168.1), and the last number will be the number you determine for the WaveCAST EIGHT D (i.e. .You can choose another number instead of .100). When you determine this address, remember or write it down. You will need it for a later step.
Set the Static IP Address for the WaveCAST EIGHT D via the web interface of the WaveCAST EIGHT D (see “Server Settings Page” on page 12).
a. Enter the IP Address you determined earlier. (When entering/saving the new address, the WaveCAST EIGHT D will automatically change its IP Address Mode to STATIC)
b. Network settings in the WaveCAST EIGHT D take place immediately after saving and rebooting.

Additional WaveCAST Servers
Several WaveCAST devices can be on the same network. WaveCAST devices include the original WaveCAST, FM+, IR+, and WaveCAST EIGHTS, along with their Dante counterparts. The number of devices that can be put on the network depends on if the device is a unicast or multicast device.
Up to eight WaveCAST EIGHTs can be on the same network, as these devices are all multicast. Adding in an original WaveCAST or FM + will lower the maximum number of devices to four, because those devices are unicast. The WaveCAST EIGHT D can adjust the maximum number of devices allowed on the network through the Max Servers on Subnet option on the webpage (See “Server Settings Page” on page 12).
This may be necessary if you have a mix of unicast and multicast devices. This setting must match on all multicast devices on the same network, or the devices will throw an error and be unable to stream. Unicast device will always be limited to 4 devices on the network, and therefore do not have a Max Servers on Subnet setting. If unicast systems are included on the network, the Max Servers on Subnet setting on multicast devices must be set to 4.
If only multicast devices are included, the maximum can be set to 4 or 8, as long as Max Servers on Subnet settings is the same on all devices. If settings are mismatched, the server will be unable to stream audio and will throw an Incompatible Server error. Devices that are missing this feature may need their firmware updated.
Audio Settings
The Audio Settings provide the ability to change the audio characteristics for different listening applications.
Audio Input Gain
The Audio Input Gain adjusts the audio output level from the WaveCAST EIGHT D. Changes to the input level will affect the level indicated by the front panel LED’s when audio is present. The gain can be adjusted from -96dB to +24dB.
Audio Presets
The Audio Presets allow the user to quickly and easily configure the WaveCAST EIGHT D for common applications. In some cases, the Audio Presets may be the only setup needed for properly configuring the WaveCAST EIGHT D server.
There are three pre-configured to choose from: Hearing Assist, Music, and Voice. When one of these selections is made, the performance of the WaveCAST EIGHT D is immediately optimized for the needs of that application (an adjustment is automatically made to the Low-pass Filter, High-pass Filter, and Compression).
By default, the WaveCAST EIGHT D is shipped in the Music mode.
For music, concerts, and other applications where the highest audio quality is desirable, Music is the recommended mode of operation.
For hearing assistance applications, or applications where the message is critical for listening, Hearing Assist is the recommended mode of operation.
For speaking and other voice applications, Voice is the preferred mode of operation.
A Custom preset is also available for configuring channel-specific audio settings.
Server Description
The Server Description field allows the user to easily identify the transmitter. This typically comes into play when multiple transmitters need to be distinguished from one another. The description appears on the front main info screen, and also on the web page. In a rack, all the user has to do is activate the main info screen with a touch of any button on the front, and the description is displayed as one of the fields on the main info screen.
The description can only be edited from the web interface.
Channel Description
The Channel Description allows the listeners to easily identify the channel. The description appears on the channel information screen, on the web page, and in the WaveCAST App. The channel description can only be edited from the web interface.
Restore Defaults
The Restore Defaults action will restore the transmitter to it’s original factory settings. Restoring defaults from the front panel of the WaveCAST EIGHT D will reset all settings.
On the front panel menu, it is hidden on the main screen (see “Restoring Defaults” on page 15).
Restoring defaults from the web page will reset all settings except Network connectivity settings (IP Address, Subnet Mask, IP Address Mode, and Web Password). This maintains connectivity between the Web Page and the WaveCAST EIGHT D, after the WaveCAST EIGHT D reboots.
In the web interface, this feature is under the Admin menu.

Web Control Interface

The WaveCAST EIGHT D provides a web interface to manage the device settings. These web pages can be accessed over either a hardwired or wireless network connection with most modern internet browsers.
Changes take effect when applied or saved. Any updates made through the front panel will show up on the web interface once the current page has been navigated away from, either by refreshing the page or going to a new page.

Open the web browser of your choice.
In the address bar of the browser, type in the IP address of the WaveCAST EIGHT D and hit Enter.
You should see the Login Page of the WaveCAST EIGHT D.
• If you only see a page asking for a firmware update, your device may have been corrupted. See “Website problems” on page 17.

Login Page
The default User name is “admin” and the default password is “admin”. The user name and the password can (and should) be changed on the website’s Admin page.
Check with your system administrator for the most recent login credentials.
Changing Channels
With the exception of some server-wide settings, each webpage is only adjusting the settings for a single channel. To switch channels, use the drop down menu near the navigation bar at the top of the screen. Switching channels will cause the device to reload with the data for the selected channel.
Main Settings Page
The Main Settings page displays all current audio settings, as well as corresponding WaveCAST EIGHT D web-based controls. It is the first page to appear when logging into the website.
An audio monitor is visible at the top of the page. It is for informational purposes only, and does not set any settings.
Note: Network speed can affect the audio monitor updating and web page performance.
The transmitter information displays which device is being edited. If needed, the description can be adjusted on the Options page.
Dante State will alert the user to the Dante connection status.

No Connection: There is no detected cable plugged into the Dante port.
No Dante Activity: There is a cable in the Dante port, but no Dante information is being provided.
Connected: Dante information is being received by the system.

Audio Input Gain adjusts the audio volume. A slider is used to adjust the gain.
The audio input source selects the type of audio source that is connected to the selected channel. Typically, this source will be Dante, but a test tone is also available.
Audio Presets adjust the sound to specific settings to improve the audio quality depending on if you are broadcasting audio that is primarily voice, music, or for an audience requiring hearing assistance. The audio settings can also be manually adjusted in the
custom presets section. See “Audio Settings” on page 8 for more details on adjusting any of these settings.

Options Page
The Options page displays user preferences that can be tailored to each WaveCAST EIGHT D channel.
The description sets the name of the channel, which may be used to uniquely identify the device without referring to the IP address.
The channel can be disabled if it will not be used for audio. Disabling the channel will keep the channel from displaying in the WaveCAST Receiver App. Channels that are enabled will appear in the app, even when not in use.
Secure Mode can be enabled or disabled, and a 6-digit PIN number can be assigned. If enabled, users will need to use this PIN to log on to the audio stream. Users attempting to listen to the stream without the PIN will be unable to do so.
The audio timeout is used to halt the audio stream when audio is not present. The system will wait the selected amount of time before ending the stream.
A multicast address can be automatically assigned. If a specific multicast address is required, the device administrator can enter the desired multicast address. Editing the multicast address will require a reboot of the device.

Server Settings Page

The Server Settings page affects settings specific to the server as a whole. The page displays network connectivity settings, as well as the server name and screen lock. Typically these are not needed after initial installation.
The screen lock will prevent the front panel on the device from being used, forcing all changes and information to be seen via the web interface. This can also be enabled and disabled from the physical device.
If audio is not streaming smoothly, adjusting the Network Compensation Buffer setting will change the time delay buffer on the WaveCAST App. Changing the buffer can be helpful when a network connection is not sending the packets of audio data at a rate that results in smooth audio streaming.
Max Servers on Submit sets the maximum number of WaveCAST servers that can be on a network. More information on this feature is available at “Additional WaveCAST Servers” on page 8.
Changing a static IP address or subnet will not instantly take place. The changed IP address or subnet will only take affect once the device is rebooted. This can be done manually or from the Admin menu
Note: If the IP address or subnet of the device was changed and the device is being rebooted, the website may not be available at the same URL location. Take note of the network information before rebooting the device.
TTL can be modified if there is a need. The recommended setting for the least latency is 1, but it can be set up to 31. This setting should not be adjusted without proper consideration for your system setup.
Additional networking information is described in “Adjusting Network Settings” on page 8.

Upload Image
An image can be uploaded that will display next to the channel name for any users listening using the WaveCAST Receiver app.
This image can be used to easily distinguish the content of your audio broadcast. The image must be under 128kB and be in PNG or JPG format. If no custom image is uploaded, a Williams AV W logo will display instead.
The image can be replaced at any time. To completely remove the image, the device must be reset via the front panel menu.

Administration Page
The Admin page displays administrative controls that can be used for remote site troubleshooting purposes.
The login username and password for the website can be set from this screen. If the username or password is ever forgotten, it can be restored to its default value by restoring defaults via the front panel menu.
Limited Restore Defaults on the web interface will reset the devices settings that will not affect the website connectivity. Using the limited restore defaults from the web interface will not reset the username or password. For a full reset, the reset will need to be performed via the front panel of the device. See “Restoring Defaults” on page 15 for more information.
Various firmware versions are viewable. These can be useful during troubleshooting when talking with TechBlue technical support.
The package version is the main firmware version. Clicking More Information will show additional version numbers.
Firmware updates are performed from the Admin page. At the bottom of the page, upload the firmware file (provided by Williams AV) and hit the update button. Your system will begin the update process from there, which will include a reboot.
Updating or rebooting the device and make the website temporarily unavailable. While the device is restoring, a message warning you to not power off the device will display on the OLED screen.

Manual Controls and Features

Power Button
The toggle switch turns the transmitter on or off. The desktop power supply provides power to the unit at all times.

This shows current status of channels and of the WaveCAST EIGHT D. Each time the power of the unit is turned on, the OLED Display shows a Williams AV start-up screen and a list of system version numbers. After seven seconds, the default Main Info Screen screen will be displayed.
NOTE: If the transmitter’s internal tests fail, the transmitter will attempt to auto-recover by rebooting itself.
Audio Input Level Indicator
The bar graph indicator shows audio level in 3dB steps at the output of the audio level processing circuit. The indicator is peak responding and is calibrated so that optimum level is reached when the VU meter only fully lit (+9dB) occasionally and typically hovers around 2/3rds lit (0dB). Adjust the audio levels from the web interface (see the web interface section’s “Audio Settings” on page 8) or from the front panel (see the front panel section’s “Main Menu” on page 14).
Input Overload Indication
The OLED Display shows an exclamation mark (!) above each channel’s VU meter as an overload warning each time the audio signal exceeds the capacity of the input circuit. Either the source of the audio coming in to the WaveCAST EIGHT D needs to be adjusted to correct this or the Audio Input Gain needs to be adjusted.
Multiple WaveCAST EIGHT Units
Up to 4 WaveCAST systems (including WaveCAST, WaveCAST EIGHT [D], FM+ and more) can be used on the same Wi-Fi network. Multiple devices will work better on more powerful networks and routers. The number of servers on the network is visible on the front panel of the WaveCAST EIGHT [D]. The number assigned to a specific server is also visible.
Main Info Screen
On the main screen, 8 VU meter bars are displayed. Each VU meter represents the audio on one channel. Channels that are disabled will be displayed in darker grey than channels that are enabled. Channels with no active audio will have an empty VU meter.
Navigating the Front Panel
The arrow buttons (up, down, left and right) on the front panel of the WaveCAST EIGHT D are used to navigate the menu. See “Web Control Interface” on page 9 for how to use the arrows on each screen.

The multicast address is visible on this screen, and will display if it is the default address or a user customized address. The multicast address can only be adjusted from the web interface.
Navigate to the bottom of the screen to exit the channel information.
When a channel is disabled, it will show up in a darker grey on the main menu. In this picture, channel 1 is disabled.

Dante Connection

A Dante port is available on the rear of the device. Only Dante audio sources may be connected through this port; there are no other audio connections.
To configure your Dante audio sources, please see the source’s manual for configuration, or your Dante systems instructions.

WaveCAST Receiver App

The WaveCAST Receiver app allows listeners to hear the audio on their personal, Wi-Fi connected devices, such as a mobile phone. The WaveCAST App can be downloaded from the Google Play Store for Android devices or the Apple App Store for iOS devices.
Download the WaveCAST App
Download the WaveCAST app from the Apple App Store for iOS devices or Google Play Store for Android devices. It is recommended that the app is downloaded in advance over an internet-connected wi-fi network or cellular network.
Join the WaveCAST Wi-Fi Network
Once the WaveCAST App is downloaded, join the same Wi-Fi network that the audio is being broadcast over. If no channels are listed when selecitng an audio channel, there is no audio being streamed on this Wi-Fi network. Ensure you are on the correct Wi-Fi network.
Select an Audio Channel

When the App is opened for the first time, a list of available channels will appear. Tap on the channel to listen to the audio. The venue should provide the name of the channel to listen to for your event if more than one is available.
Channels marked with a lock icon require a code to join. Enter the join code assigned to the channel when prompted. If a channel is currently streaming, it will have a blue checkmark next to its channel name.
If there are many servers on your network, or your network is set so that servers cannot be discovered by outside devices, the WaveCAST app can connect to a server via IP address. Tap the Discover by IP text at the bottom of the channel screen then enter the IP address of the WaveCAST server. The channels being broadcast by that server will then be available on the channel select screen. It is recommended that this feature is not used with a general audience as they may not type the IP address correctly.
Listen to the Audio
Once an audio channel has been selected, the audio should start playing automatically. The volume of the audio can be adjusted using the slider in the middle of the screen, or with the physical volume controls on the personal device.
To mute the audio, tap the speaker icon. Tap it again to unmute the audio.
To switch channels, hit the back arrow at the top of the screen.
Note on Wi-Fi Assist/Smart Network Switching
The WaveCAST does not require an internet connection. It can be placed on an internal network with no internet connection.
Some phones expect network connections to provide internet access. When the phone cannot reach the internet, it may automatically try to switch to a network connection with an internet connection. Sometimes, the phone determines that the best internet connection is through a mobile data network.
This is not the desired behavior when using the WaveCAST network. The phone will automatically take the user off of the WaveCAST audio streaming network, and onto a unrelated internet network connection. This will prevent the user from hearing the audio, and they may not realize their phone switched networks on them.
Steps for disabling this feature will differ for every phone, but is typically found under the Wi-Fi or Mobile network settings. Look in the manual for your phone for instructions on disabling this feature.

Troubleshooting

Incompatible Server Error

The Max Servers on Subnet setting does not match on all servers on the network. See “Additional WaveCAST Servers” on page 8 for details on how to properly set up your
WaveCAST system network.
Ethernet Light Troubleshooting
The LED lights on the Ethernet port can be used to help troubleshoot issues. The following chart explains the light pattern’s meaning:

LIGHT	MEANING
Right LED Off	No detected connection to a router
Right LED On	Router Detected
Left LED Off	Audio Transmission Disabled
Left LED Orange	Servers on sub-net syncing
Left LED Green	Servers on sub-net synced; Audio transmitting

Website problems
The full website is unavailable.

If you are only able to install a firmware update, the website stored on the WaveCAST EIGHT D has been corrupted, likely by a power outage. Install the firmware for your current version (or newer) of the WaveCAST EIGHT D via the firmware update page to restore the website.
Check your network settings. The IP address is viewable on the front panel of the device.

Lost username or password

Using the front panel menu, restore defaults. See “Restoring Defaults” on page 15.

Website not behaving as expected

The website will only work with a modern browser. Do not use the website with IE11 or earlier.
Try switching browsers. Google Chrome is our recommended browser.

Audio problems
Noise or Distortion in the Audio

Check to see if there is noise in the audio source. To find out, disconnect the audio cable. If the noise disappears your noise problem is in the source. Correct or repair your audio source.
Check for ground loops or noise on the input signal. If you are still having trouble, call your Authorized Williams AV dealer or representative.
If audio sounds clipped or is too loud, try to turn down the gain for the channel. These issues may be more noticable if the VU meter for the channel is displaying the ! overload warning.

Noise in audio grows when program is silent

Check the WaveCAST EIGHT D Compression Ratio, which may be inappropriate for the type of program being transmitted. Try setting the Compression Ratio to 1:1 (compression off). See “Audio Settings” on page 8.

Reception or App difficulties

No Reception

Ensure the listeners have the correct app open are listening on the same channel as the WaveCAST EIGHT D.
Ensure the phone is on the correct Wi-Fi network.

Missing Channel Image on App

Images may not load when many users are connected. Try reloading the list of channels.

Users must turn receiver volume controls way up (near maximum) to get enough volume

The audio gain control may be set incorrectly on the transmitter. Correct the Audio Gain control setting by adjusting it until the sound level peaks between 0 and 6 dB.
Some users may not be helped by this system. Severe hearing loss may require using the system with a T-coil and personal hearing aid rather than headphones. Some phones and tablets have the ability to broadcast to a T-coil; research the phone model to see if this is an option.

Buzz in other equipment when transmitter is on or off

This is likely caused by incorrect audio connections, a ground loop, or defective equipment. To remedy, use proper audio wiring practice to make connections.
Make certain the transmitter chassis is connected to the equipment cabinet rails. Buzz/hum in system may be experienced when the WaveCAST EIGHT D chassis is insufficiently grounded. In this case, install a ground wire to the WaveCAST EIGHT D chassis and terminate to a verified ground source.

Device is not working over the hardwired Ethernet network
Note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself.
The following steps are things you can try on a small, non-managed network.
In this situation you have to check the entire signal path between the control device (laptop or desktop computer) and the WaveCAST EIGHT D. You can save some time by pinging the router and WaveCAST EIGHT D. Pinging allows you to verify the wiring path without physically having to trace the wires themselves.

In order to perform these steps you will need the IP address of the WaveCAST EIGHT D and the router. You can find the IP address of the WaveCAST EIGHT D via the menu on the front screen of the device.
Make sure the WaveCAST EIGHT D, Router, and any other devices that may be needed (such as an Ethernet switch) are all connected and powered on. You can save time tracing wiring/hardware paths with these next three steps:
Open a CMD window on the computer. (For example, on Windows 10 computers, in the search box, type “CMD”. A black box should come up and the cursor will be blinking.)
Type “ping” followed by a space, followed by the IP address of the WaveCAST EIGHT D, and hit Enter. If you see a “reply from…[IP address]” this means the hardwired Ethernet path is OK. If you see “request timed-out”, there is most-likely a break in the wiring path between the computer and the WaveCAST EIGHT D.
Try pinging the IP address of the router. If you can get a “reply from…” the router, but not the WaveCAST EIGHT D, the problem is either in the wiring between the router and WaveCAST EIGHT D, or the WaveCAST EIGHT D itself could be malfunctioning.
Check all of the wiring between the computer and the WaveCAST EIGHT D. Make sure every device in the signal path is plugged in, connected, and powered on. Unplug and plug back in firmly all Ethernet cables in the path between the computer and the WaveCAST EIGHT D. If you find one that was loose, plug it in and test the device connection again. If none are loose, you could also replace Ethernet cables.
Note: When checking connections, make sure the WaveCAST EIGHT D Ethernet cable is plugged into one of the LAN ports on the router, not the WAN port.
If no loose cables were found, try re-booting in this order
the router
the computer
the WaveCAST EIGHT D (turn it off for 10 seconds then turn it back on)
Wait at least two full minutes for the WaveCAST EIGHT D to re-establish itself on the network. Then try testing the connection again.
Once you have verified that you can ping the WaveCAST EIGHT D from the computer, open an internet browser on the
computer. Type the IP address of the WaveCAST EIGHT D into the address bar of the Internet browser.
Verify the connection by changing a setting on the WaveCAST EIGHT D through the internet browser. If you can change settings and get feedback on the web page (or verify the change on the front display of the WaveCAST EIGHT), you are now connected to the WaveCAST EIGHT D.
If you can make changes to the WaveCAST EIGHT D initially, but then lose that ability (get disconnected), you may have to look at network issues such as IP address conflicts, power issues, or even settings in the router.
You can try restoring the WaveCAST EIGHT D to factory settings. This will clear out any changes and allow you to start clean.
Try directly connecting the WaveCAST EIGHT D’s Ethernet cable to a PC to verify that the WaveCAST EIGHT D and Ethernet cable are operational.
If you have tried all of these steps and still can’t connect, call Williams AV for additional troubleshooting help. Note that Williams AV cannot help in all cases, as there are many variables within networks.

Device is not working over Wi-Fi
Note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself.
If you don’t have a system administrator, the following steps are things you can try on a small, non-managed network.
This situation is most often caused by the mobile device losing connection to the router when the Wi-Fi on the mobile device has been turned off (or the Wi- Fi reception is unstable).

In order to perform these steps you will need the SSID of the router, the router Wi-Fi connection password, and the IP address of the WaveCAST EIGHT D. You can find the IP address of the WaveCAST EIGHT D by going into the Menu on the WaveCAST EIGHT D itself (using the front buttons and display).
Make sure the WaveCAST EIGHT D and router are both ON.
Make sure the Ethernet cable going to the WaveCAST EIGHT D is plugged into one of the LAN ports on the router (not the WAN port).
Is the mobile device connected to the router? On the mobile device, go into the Wi-Fi Settings, and make sure Wi-Fi is turned on or enabled. More than one router may show up in the list of possible connections, depending upon how many routers are nearby. If you don’t see the router that is connected to the WaveCAST EIGHT D in the list, make sure the router is on and broadcasting it’s SSID.
If you see the desired router SSID in the list, connect to it by clicking on it. Usually there is a check mark or some other indication of which router/SSID you are connected to. You may need to enter the Wi-Fi password/passkey to the router to connect to it.
Once you have verified that you have connected the mobile device to the router, exit the Wi-Fi settings on the mobile device (without shutting off the Wi-Fi) and open an internet browser. Type the IP address of the WaveCAST EIGHT D into the address bar of the Internet browser and hit the Enter key. You should see the WaveCAST EIGHT D login web page come up.
Verify the connection by changing a setting on the WaveCAST EIGHT D through the internet browser. If you can change settings and get feedback on the web page (or verify the change on the front display of the WaveCAST EIGHT D), you are now connected to and controlling the WaveCAST EIGHT D.
On the portable device, attempt the following steps:
• Enable Network Permissions for the Wavecast App
• Disable Private IP Addressing
• Disable Random MAC address
• Reopen App or Reboot portable device
Try re-booting in this order
the router
the computer
the WaveCAST EIGHT D (turn it off for 10 seconds then turn it back on) Wait at least two full minutes for the WaveCAST EIGHT D to re-establish itself on the network. Then try testing the connection again.
If you can make changes to the WaveCAST EIGHT D initially, but then lose that ability (get disconnected), you may have to look at deeper network issues such as IP address conflicts, power issues, or even settings in the router.
If there is interference, or low Wi-Fi signal on the mobile device, try moving the router to a better location.
Some mobile devices have known issues with certain routers. To fix this, you can investigate updating the operating system on the mobile device. Try a different mobile device just to verify that ANY wireless device can connect. If you can get one device connected, but not another, chances are the device that cannot connect has issues. A different brand/model of router may also fix the problem with certain devices not connecting.
You can try connecting a computer directly to the WaveCAST EIGHT D with a standard Ethernet cable to verify that the Ethernet connection on the WaveCAST EIGHT D is working. Once this has been verified you can place the WaveCAST EIGHT D back on the network and begin troubleshooting back to the mobile Wi-Fi device.
Try connecting to the WaveCAST EIGHT D using Wi-Fi on a laptop, rather than a mobile device, to verify that the mobile device is/is not the problem. If you can connect with a laptop, check the Wi-Fi settings on the mobile device and make sure Wi-Fi is turned On.
You can try restoring the WaveCAST EIGHT D to factory settings. This will clear out any changes and allow you to start clean.
If you have tried all of these steps and still can’t connect, call Williams AV for additional troubleshooting help. Note that Williams AV cannot help in all cases, as there are many variables within networks.

Checking Software Versions

The Max Servers on Subnet setting does not match on all servers on the network. See “Additional WaveCAST Servers” on page 8 for details on how to properly set up your
WaveCAST system network.
Ethernet Light Troubleshooting
The LED lights on the Ethernet port can be used to help troubleshoot issues. The following chart explains the light pattern’s meaning:

LIGHT	MEANING
Right LED Off	No detected connection to a router
Right LED On	Router Detected
Left LED Off	Audio Transmission Disabled
Left LED Orange	Servers on sub-net syncing
Left LED Green	Servers on sub-net synced; Audio transmitting

Website problems

The full website is unavailable.

• If you are only able to install a firmware update, the website stored on the WaveCAST EIGHT D has been corrupted, likely by a power outage. Install the firmware for your current version (or newer) of the WaveCAST EIGHT D via the firmware update page to restore the website.
• Check your network settings. The IP address is viewable on the front panel of the device.

Lost username or password

• Using the front panel menu, restore defaults. See “Restoring Defaults” on page 15.

Website not behaving as expected

• The website will only work with a modern browser. Do not use the website with IE11 or earlier.
• Try switching browsers. Google Chrome is our recommended browser.

Audio problems
Noise or Distortion in the Audio

Check to see if there is noise in the audio source. To find out, disconnect the audio cable. If the noise disappears your noise problem is in the source. Correct or repair your audio source.
Check for ground loops or noise on the input signal. If you are still having trouble, call your Authorized Williams AV dealer or representative.
If audio sounds clipped or is too loud, try to turn down the gain for the channel. These issues may be more noticable if the VU meter for the channel is displaying the ! overload warning.

Noise in audio grows when program is silent

Check the WaveCAST EIGHT D Compression Ratio, which may be inappropriate for the type of program being transmitted. Try setting the Compression Ratio to 1:1 (compression off). See “Audio Settings” on page 8.

Reception or App difficulties
No Reception

Ensure the listeners have the correct app open are listening on the same channel as the WaveCAST EIGHT D.
Ensure the phone is on the correct Wi-Fi network.

Missing Channel Image on App

Images may not load when many users are connected. Try reloading the list of channels.

Users must turn receiver volume controls way up (near maximum) to get enough volume

The audio gain control may be set incorrectly on the transmitter. Correct the Audio Gain control setting by adjusting it until the sound level peaks between 0 and 6 dB.
Some users may not be helped by this system. Severe hearing loss may require using the system with a T-coil and personal hearing aid rather than headphones. Some phones and tablets have the ability to broadcast to a T-coil; research the phone model to see if this is an option.

Buzz in other equipment when transmitter is on or off

This is likely caused by incorrect audio connections, a ground loop, or defective equipment. To remedy, use proper audio wiring practice to make connections.
Make certain the transmitter chassis is connected to the equipment cabinet rails. Buzz/hum in system may be experienced when the WaveCAST EIGHT D chassis is insufficiently grounded. In this case, install a ground wire to the WaveCAST EIGHT D chassis and terminate to a verified ground source.

Device is not working over the hardwired Ethernet network
Note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself.
The following steps are things you can try on a small, non-managed network.

In this situation you have to check the entire signal path between the control device (laptop or desktop computer) and the WaveCAST EIGHT D.
