Audio Output Module with Balanced Outputs
Our Audio Output (AO) module allows you to add balanced outputs to your modular system, for connection to an external device such as an audio interface or mixer etc.
It has 3.5mm stereo inputs; the left input is normalled to the right input, allowing it to also be used as a mono input.
1/4" balanced stereo outputs are included; each with its own independent attenuator. The maximum output level is unity-gain.
A pin connector on the PCB also allows the outputs to be internally connected to our Dual VU Meter module to provide a visual representation of the output level.

These merchants probably sell this module. Huh?
