The ZC-8 is a push button Volume Control and Source Selector. The example below shows a ZC-8 being setup as ID#1.
In this configuration page you can name the ZC panel and give it gain limits, from a Minimum of -inf to a Maximum of +20 dB. It can also be setup with input selections for each position (A, B, C, D) on the ZC-8 selector switch.
