What is the name of the switch on an audio device input channel used to send that input channel's audio to a specific output?

The channel assign switch on an audio device input channel is specifically designed to route the audio signal from that input channel to a predetermined output or set of outputs. This function allows an operator to designate which audio signals are sent to various outputs, such as a mix bus, speakers, or recording devices. By utilizing the channel assign switch, users can control the flow of audio and create customized mixes for different listening environments.

In contrast, the channel mute switch is intended to silence the audio from that channel without completely removing it from the mix, which does not facilitate routing. The output control switch adjusts the volume of the output but does not determine the routing of the audio signal itself. The input level switch adjusts the gain or level of the input signal but again does not serve the purpose of directing the audio to specific outputs. Thus, the channel assign switch is uniquely suited for controlling audio routing among the options provided.
