MC2 310W RMS Stereo Amplifier Information.

Mid Continent Controls, Inc. offers a 6 channel stereo amplifier that provides 310W RMS and will accept either line level or high level audio input levels. Selectable crossover networks are incorporated to configure the output channels providing 4 high pass and 2 subwoofer outputs. An internal volume control has been incorporated into the amplifier, which eliminates the need for additional expensive modules to control volume levels. In the event our clients would prefer to use other means of controlling volume, our amp is configurable to identify this option and ramp the internal volume control to full output, thus allowing you to control the volume externally.

We have also incorporated a PA mute input to shut the amplifier off during passenger briefing messages. A speaker on/off input is provided to allow remote operation and for flexibility in designing your system, our amplifier will accept a +12VDC, +28VDC or DC ground input for the remote on/off. Trim and gain adjustment potentiometers are provided for both the high and low pass sections, with a diagnostics LED being provided to assist in the proper adjustment of these output sections.
