  • Quick Install Guide

The Barix Multicoder is an audio over IP encoder with a line-level input on stereo RCA connections.


STEP 1 Connect the Audio Equipment

The Multicoder provides an unbalanced line level input (nominal at 0dBu), to be connected to a mixer,
an audio source, etc. To listen the IP address of the device directly after reboot, also a headphone
should be connected to the headphone output.

STEP 2 Connect the network

Connect your Multicoder to the network using a standard Ethernet cable (CAT5e or better).

STEP 3 Connect the power supply

Plug the power chord into the power connector on the back panel of the device. The device will boot:

  • Right after power-up both status LEDs are red (boot in process)

  • 15s after power-up → Device announces its IP Address over the headphone output (take note to be able to enter the web interface later) → Left LED turns from red to green

  • 34s after power up → Application is ready → Right LED is slowly blinking

Multicoder is ready to be configured.

First Configuration


From a PC in the same network subnet of the device, use a web browser to access the web interface by typing the IP Address into your browser (the one noted during boot)


Login is required, by default user is "admin" and the password is provided on the sticker on the backside of the device (PW label)


On the “Home” page you get information about the application status.
You should see “Multicoder” on the top of the page and Application Status “running”.
That means the device is prepared and ready with the correct software.
If you don´t see, then make your your device is connected to the Internet and click “Sync”.
Thereafter the device will validate the software state with the Barix registration server.



Go to the “Settings” Page, after a short moment you will get a “Multicoder Settings” button, where you can configure the the audio/codec settings. Click on it and configure the Audio settings.


For the initial version 1.0.2 make sure the “Configuration Source” is set to “local”.

Note, the Configuration Source “Cloud” is not working in this version. It will supported in the future.


When done, click “Submit”.


Thereafter click on “Stream” to configure the stream settings and the streaming targets.
Here define which codec and format the streaming should have and even where the Multicoder should stream to. If needed, add more encoders and stream destinations.



When done, click “Submit”. The streaming to configured target will start directly thereafter.
