[. . . ] All warnings on the unit and in the operating manual should be followed. Operate the unit only from a power source of the appropriate voltage indicated on the rear panel. Do not use a damaged or deformed power cord as it may cause electric shock. When removing the plug from the wall outlet, be sure to remove by holding the plug attachment and not by pulling the cord. [. . . ] Your investment in a Marsh product means that you can forget about the hardware and focus on years of enjoyment. So - set your course for the music . 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.

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.
