Speaker Connections

The NPA20DA supports low Impedance (4-8ohm) speakers. It is necessary to configure the Speaker Impedance Switch as well as wire up the speakers according to the specific speakers you are using. Wiring examples for each of the available configurations are as follows:

Low Impedance (4-8ohm) Stereo Speakers:

Low Impedance (8ohm) Mono Speaker:

Amplifier Output

The NPA20DA amplifier is capable of outputting the same power at both 4 ohms and 8 ohms. The amplifier output power varies depending on the input power supply or PoE adapter connected to it, it does this by adjusting the internal gain to allow you to get the most of the amplifier. Please ensure that you select the correct impedance option via the speaker impedance selection switch on the rear of the device.

Trigger Connection

The NPA20DA features a trigger input to allow 3rd party devices to trigger the units power on or off. When the trigger input senses a low voltage level (0V) it will enable the amplifier output, while when it senses a high voltage level (5-12V) it will disable the amplifier out. This feature is enabled by default, and can be adjusted via the web-GUI, or control API.
Dante® Audio & Dante® Controller

Dante® Controller software is required in order to setup and configure the NPA20DA as well as control your Dante® network. Audinate provide extensive training videos and documentation on their website. This can be found here:
http://www.audinate.com/products/software/dante-controller  Upon connecting the NPA20DA to a compatible network, the Dante® Controller software should automatically discover the device. The NPA20DA will appear in the Dante® Controller with the name “NPA20DA”. On the “Routing” screen it is possible to then create audio routing between Dante® transmitters and receivers within the same system.
Please ensure your PC is on the same network as your Dante® devices. Dante is not able to transmit over WiFi and it is recommended to hardwire into the Dante® network. Having multiple network devices enabled can also confuse the Dante® Controller software so it is recommended to disable WiFi during configuration.

It is possible to change various Dante® related settings of the NPA20DA under the “Device Info” screen in the Dante® Controller software. To do so, select the “Device Config” menu.
Here it is possible to adjust the sample rate of the NPA20DA. Please note: that Dante® products can only transmit or receive audio from other Dante® products that are set up with the same sample rate. A mismatch in sample rate may stop audio from transmitting.
Under the “Device Config” screen the latency of the NPA20DA can be configured from 2-10 milliseconds.

Web-GUI Control
The NPA20DA features an in-built web-GUI for control and configuration of the unit. By default the device is set to DHCP, however if a DHCP server (eg: network router) is not installed the device IP address will revert to below details:
Default Username : blustream Default Password: 1234 Default IP Address: 192.168.0.200
The device can also be accessed via its mDNS name which is defaulted to: http://NPA20DA.local/
The web-GUI supports multiple users along with multiple user permissions as follows:
Guest Account – This account does not require a user to login. The Guest account can only adjust the output volume of the NPA20DA. Guest access can be enabled or disabled by the Admin if required.
User Accounts – User accounts can be utilised, each with individual login details. User accounts can be assigned permissions to specific areas and functions. A User must log in to make use of these functions.
Admin Account – This account allows full access to all functions of the unit as well as assigning users with permissions as required.
Login Page:
The Login Page allows a user or admin to login and access additional functionality within the web GUI.

Once a user is selected from the list it is required to enter the pasword for that user in order to sign in.

Please note: the first time the Admin logs into the web GUI, the default admin password will need to be changed. It is important to record this password as there is no way to recover it in the event that it is forgotten.

Guest Control Page:
The Guest Control Page allows a guest to adjust the master output volume of the unit by using the volume slider or the volume up / down buttons as well as the mute toggle button.

User Control Page:
The User Control Page allows a user to adjust the volume for the input our output, as well as mute the audio signal.
The input volume adjustment could act as an audio limit function to limit the maximum output volume. A User can also adjust the signal mix (single channel only, stereo, or summed mono), audio delay, or 31 band graphic eq with +3dB / -10dB of adjustment.
The user can also update their password via the Update Password button, or log out via the Log Out button.

User Page:
The Users page allows the admin to add, remove or disable users. Updating passwords of a user can be carried out from here also.
