Operating Precautions
Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty. See the Connecting Power section for more information on voltage requirements.
Note: Always turn off and disconnect the amplifier from mains voltage before making audio connections. Also, as an extra precaution, have the attenuators turned down during
Although the CS 2000H amplifier has RampUp™ circuitry, which raises the signal level gradually after the output relay closes, it is always a good idea to have the gain controls turned down during
Consult the Wire Gauge Chart (below) to determine proper gauges for different load impedances and cable lengths. Remember that cable resistance robs amplifier power in two ways: power lost directly to resistance (I2R loss), and by lowering the total load impedance. Also make sure the mode switch is correctly set for the desired application. See Sections on Stereo, Parallel and Bridged Mono operation for more information.
