The M4 microphone processor comes standard with the full control user interface and is the interface used by the majority of end users.

The full control interface provides unrestricted access to all four channels of microphone processing and has the ability to create, save and recall presets. Sometimes users require less control, however, so we created a series of simplified interfaces which allow a more restrictive set of operations, either on all four channels of processing, or on just one channel of the four.

One type of interface grants access to all four channels of microphone processing but limits access to preset recall, microphone gain and phantom power on and off.

Another type of interface grants access to all four channels of microphone processing, but only allows preset recall.

Another type of interface grants access to just one channel of processing and only allows preset recall, microphone gain and phantom power on/off.

Another type of interface grants access to just one channel of processing, and only for preset recall.
