The MSD-A200S The A200S gives out 120 watts per channel, for a total of 240 watts. The A200S is designed with a High End circuit with very low-noise FETs. A balanced, complimentary differential input circuit makes the A200S even more linear than other systems. The output stage has two pairs of high current, paralleled, bi-polar power transistors to meet the peak current demands of any speaker system. Servo-controlled, direct-coupled circuitry is used throughout the circuitry for extremely high resolution sound.

REMOTE IN This is a digitally controlled input designed to receive +12VDC from others MARSH SOUND DESIGN preamplifiers with remote Turn on capability or from other equipment e. g. With this function, the MSD-A200S can be powered ON/OFF synchronized with that equipment. SPEAKERS Marsh 11 Internal Protections 1. OVER-CURRENT PROTECTION The MSD-A200S will go into protect mode and cut off the main power supply to protect the amplifier and speakers. This usually happens when the speaker terminals or wires are accidentally shorted together. The MSD-A200S will go into protect mode when it detects DC voltage at the speaker output. This is caused by a DC voltage leak from the pre-amplifier outputs or by an internal fault that gives a DC voltage leak at the speaker output. 2. DC-FAULT PROTECTION When in the above mentioned protect mode, the unit will shut down to prevent damage to itself or the speakers.
