MC2 Audio Distribution Amplifier Information.

Mid Continent Controls, Inc. offers an audio distribution amplifier that is designed to be the cornerstone or our headphone audio system. It provides source selection and status feedback to the headphone switch panels. Our audio distribution amp can be configured for up to 4 stereo inputs, independently distributed to 10 stereo outputs. The number of sources, 1 to 4, is customer configurable simply be setting switches provided on the module. The source information is communicated to the switch panels, eliminating the need for complicated programming sequence at the switch panel.

A mono PA audio input is provided to allow passenger briefings over the headphone system. A chime mute input provides a 3 second interrupt of all output channels. Trim/gain potentiometers are provided which allow level adjustments of the PA and input sources. This provides source matching to prevent one source being louder than the next during switching operations.
