GETTING STARTED

PREP YOUR NETWORK

New Installation Steps

• Do not install your VSSL before checking your network.
• Analyze your existing network topology.
• Login to your network equipment.
• Make adjustments according to network settings suggestions.
• Reboot your networking equipment.

Recommendations

• Recommended – Download speeds of at least 1Mbps
• Not recommended – Satellite internet, 3G/4G/LTE hotspot or cellular INTERNET
• Not supported – Guest WiFi networks, shared networks

Network Topology Best Practices

• In homes with access points, it is recommended that an AP controller be present and that all access points be consolidated to a single switch. The VSSL should be installed within that same switch.
• In homes with a switch, ensure the switch is placed downstream from the router.
• In homes with 2 routers (e.g. modem/router combo unit from ISP and 3rd party router) ensure the ISP router is placed in “Bridge Mode” in order to avoid a Double NAT.
• Do not connect your VSSL via ethernet cable to access points, mesh points, or network extenders.
• Ensure that the ethernet (patch) cable is fully functional. Note: ethernet cables commonly degrade over time.

General Router Settings
To configure your router, it’s important to consult the manual that corresponds with your exact router model.

• Ensure the router has the most up-to-date firmware installed.
• Avoid Double NAT when using 3rd party router/mesh system by placing the ISP router in “Bridge Mode” (e.g., Google, eero).
• Ensure that the ethernet (patch) cable is fully functional. Note: ethernet cables commonly degrade over time.
• Separate the 2.4GHz and 5GHz WiFi bands and ensure that they maintain different SSID’s.
• Enable “UPnP” (Universal Plug and Play).
• When using access points, disable “AP Isolation” or “Client Isolation”.
• Enable “Multicasting” (multicast terminology differs between manufacturers).
• Disable “IPv6” and only use “IPv4”.
• Enable “IGMP” (Internet Group Management Protocol).
• When using Apple devices, enable “Bonjour” or “ZeroConf Discovery”.
• Ensure managed switches and access point controllers follow the same network topography suggestions as detailed above.
• See more router-specific suggestions at vssl.com/support.

PLAN YOUR AUDIO SYSTEM

Your A.3x requires a connection to your high-speed network via ethernet cable.

Plan how each device within your audio system will be connected and where they will be located within your home. Ensure that you follow all speaker, subwoofer and external device manufacturers’ guidelines for wiring and powering. As each zone of your A.3x is stable down to 4 ohms, ensure the speaker impedance load for each channel does not fall below 4 ohms.

INSTALLATION OPTIONS

Tabletop – Ensure the location has adequate ventilation and at least 0.5” of headroom above the device. If you are going to stack multiple A.3x devices on top of each other, you must use the magnetic feet attached to the bottom.
Rack – Use the included rack mount ears to install the A.3x into a rack. It is recommended to have at least 0.5” of head room above the A.3x.
Wall Mount – The built-in mounting ports are designed to fit a standard

8 or #6 drywall screw. Use the included template to locate where to position

the screws.

DOWNLOAD THE VSSL APP

Once you’re ready to set up your A.3x, download the app from the app store on your mobile device. Open the app and we’ll guide you through connecting and setting up your A.3x.

PLAYING MUSIC

Listening to music with VSSL is easy. Just play music in your favorite music streaming app, choose your preferred streaming method, and select the zone(s) to play to.

AIRPLAY 2
Use AirPlay 2 to stream music, podcasts, radio and more directly from your favorite apps to your A.3x. With AirPlay 2, you’re in control of your audio. If you have more than one VSSL zone within
your home, you can enjoy your favorite music or podcasts throughout your house — in perfect sync. You can even play different songs in different rooms.

CHROMECAST BUILT- IN
Chromecast built-in is a platform that lets you cast your favorite music from your phone, tablet or laptop right to your speakers. Easily control your speakers with apps you already know and love from
your iPhone®, iPad®, Android phone or tablet, Mac® or Windows® laptop, or Chromebook.
With Chromecast built into your VSSL A.3x, your phone becomes your remote. Simply tap the Cast button from the app to stream music/tunes/podcasts/ playlists from your phone, tablet or laptop
to your VSSL A.3x.

Note: Go to the Chromecast built-in website for a full list of Chromecast enabled apps. https://www.google.com/cast/apps
For configuring groups and volume control of Chromecast sessions, you must use the Google Home app. The Google Home app is available on iOS and Android.

SPOTIFY CONNECT
Use your phone, tablet or computer as a remote control for Spotify. Go to spotify.com/connect to learn more.
Note: The Spotify software is subject to third party licenses found here: www.spotify.com/connect/third-party-licenses

ALEXA CAST

Alexa Cast allows you to play (cast) and control music on any of your VSSL zones from your Amazon Music iOS or Android app. Your devices do not need to be on the same WiFi network as your mobile device and you can target any VSSL zone from anywhere. Your app becomes a remote control for your A.3x.

LOCAL MUSIC LIBRARY
For local music you can use any DLNA, Chromecast, Alexa, or AirPlay-based streaming app to play content to your VSSL A.3x. You can also use these apps to access local music from a NAS drive. See
instructions for External Audio Source (Input).

EXTERNAL AUDIO SYST E M (OUTPUT)
You can connect your A.3x to an external amplifier system (e.g., home theater receiver, high-powered amplifier, outdoor audio system). The A.3x is capable of acting as the source in these systems.

1. Connect the external amplifier to one of the analog outputs.
2. The output by default is variable, which allows you to control the volume of the external system from your phone or other streaming devices. A fixed output can be configured in the VSSL app.
3. Within the VSSL app’s device settings, assign whichever of the 3 zones that will supply the line-level signal to the specified output.

EXTERNAL AUDIO SYSTEM ( INPUT )
You can connect your A.3x to the audio output of any device. Wire the output of any audio  source to any of the local inputs (e.g., satellite TV box, record player).

1. Connect the external audio source to the A.3x optical, analog, or coaxial input.
2. If the external audio source has an IR remote, connect the provided IR sensor on the back panel and learn its controls through the VSSL app.
3. Set priority to “Local first” within the VSSL app’s zone settings.
4. Within the VSSL app’s “Zones” section, select the desired zone’s RCA icon, then choose the corresponding input to be assigned.

Note: By default, the A.3x sets priority to “Streaming first” in the case that 2 sources are attempting to play to a zone.

CONNECTING A SUBWOOFER
A subwoofer is a great way to add more bass to your VSSL system.

1. Connect the subwoofer to one of the A.3x’s analog outputs. You can also use a Y RCA adapter to combine the stereo inputs to a mono RCA input on the subwoofer’s amplifier. The bus outputs are full range outputs. For best results, reference the subwoofer amplifier manual to ensure the RCA input is passed through the local crossover on the subwoofer.
2. Within the VSSL app’s device settings, assign the analog output used to whichever of the 3 zones that will supply the line-level signal to the subwoofer.
3. Within the VSSL app’s zone settings, adjust the crossover settings as desired.

Note: To connect to a subwoofer with high-level speaker outputs, you will need to use an amplifier that is capable of receiving a high-level input signal. Reference the subwoofer amplifier manual to ensure proper connection and settings.

VOICE CONTROL

GOOGLE ASS I STANT
The VSSL A.3x works seamlessly with the Google Assistant.
Using Google Assistant on your Android, Google Home speaker, or other certified Google Assistant device you can say things like:

• “Play some music in the master bedroom”
• “Stop the music in the kitchen”

You can even set the default playback from your Google Home speaker to shorten your phrases to:

• “Play music”
• “Turn up the volume”
• “Stop”

AMAZON ALEXA
For the first time ever, VSSL now supports Amazon Alexa! Control your VSSL zones with Alexa’s music skills and automation.

Simply login to your Amazon account through the VSSL app interface. Your VSSL zone is then instantly available within the Alexa app. In the Alexa app, change the name of the zone and add it to a group under “Set Up Multi-Room Music.”

APPLE SIRI
As a certified AirPlay 2 product, you can use your A.3x with Siri on your iPhone, Mac, or Apple TV. Using Siri, you can say things like:

• “Play ‘I Want It All’ by Queen on all speakers”
• “Play something I like on all speakers”
• “Play some rock on kitchen speaker”
• “Play/pause music”
• “Play the next song”
• “Play the song before this one” etc.
• “Repeat last song/album/playlist”
• “Fast forward 30 seconds”, “Rewind 10 seconds”, etc.

To use Siri with your A.3x, you must first add the device to your home in the iOS Apple HomeKit app. Please follow the recommended procedure from Apple. See the following support article: https://support.apple.com/en-us/HT208724

VSSL APP

INITIAL SETUP
When your A.3x is plugged into power, the VSSL app will automatically recognize your device and initiate setup. Simply follow the prompts to name your zones and choose how you would like to stream to your amplifier.

PLAYBACK & VOLUME CONTROL
One the home screen, you will be directed to a list of available zones on your WiFi network.
Here you may adjust the volume of each zone, control the playback on existing streams, and assign external input sources.

PAGING
Your A.3x can turn any and all zones into an internal paging system.

• Upon entering the app, simply tap the microphone icon at the top right of the screen, press and hold the desired zone to page to, then record your message.
• The page volume can be adjusted in the settings as long as you are logged into the app with your email.

IR CONTROL
Your A.3x can learn IR codes to control your TV’s or control system’s volume with its original remote.

• Connect the included IR cable to the IR Remote port on the back panel.
• In the VSSL app under “Zone Settings”, with the remote in hand, follow the prompts on the screen to choose which zones to control and learn the IR codes for Volume+, Volume-, and Mute functions.

MAX VOLUME
You can set volume limits on any of your zones by adjusting the left and right channel max volume slider. For your convenience, the app acts as an SPL meter and calculates the current sound pressure in decibels (dB).

PRIORITY
By default, the A.3x sets priority to “Streaming first” in the case that 2 different source types are attempting to play to a zone. For scenarios where you desire to have the local input take priority over a stream, toggle the zone’s priority setting to “Local first.” This is especially helpful in cases where speakers are being used for both TV watching and listening to distributed audio.

EQ SETTINGS
You can fine tune any of your zones to improve & tailor your listening experience.

• Toggle on “Enable EQ” and adjust the basic treble, mid, and bass preset sliders.
• Finer frequency range adjustments can be made under “Advanced EQ.”
