Using Music on Hold (MoH)
Quest Commercial mixer amplifiers offer music-on-hold functionality for linking to a commercial telephone system. With
this feature, when customer calls are put on hold, they can listen to background music from an external or internal
sound source. You can also use this function to play pre-recorded messages while waiting.
To determine the volume of the music on hold function, use the MOH Level control located just next to the MOH
connector.
