Peavey CS-400 User Manual

the fan should be operated on the high speed position. For normal home use, the high speed fan operation might be objectional due to excessive fan
noise. In this case, the low speed should be selected. In any event, reliable operation is assured even if low fan speed was selected due to the
internal thermal sensor system which will automatically raise fan speed and ultimately set the high temperature limit of each heatsink. Care must be
taken to avoid any blockage of the fan itself or the exhaust ports at the side of the unit.
MODE SWITCH
The mode switch (14) located on the rear panel should normally be in the stereo position. Unless the amplifier is to be used in a commercial
sound distribution (70-volt line) system, the bridge mode should not be used. In certain crossover applications, accidental switching to the
bridge mode could destroy the speaker systems.
The CS-400 ™ power cord (16) is a heavy-duty type with a conventional A.C. plug with a ground pin. It should be connected to a circuit capable
of at least 15 amps continuous, or greater. If the socket used does not have a ground pin, a conventional adaptor should be used and the third wire
grounded properly. Never break off the ground pin on a line cord of the CS-400 ™ . The use of extension cords should be avoided, but if necessary,
always use a three-wire type with at least a No. 16 wire size. The use of lighter wire will severely limit the power capability of this amplifier.
The CS-400 ™ is fused with a standard 8-amp fuse (15). Always replace with the same type and rating. Failure to do this could void the warranty.
PATCH PANEL
The crossover patch panel of the CS-400 ™ provides the user with a very flexible system to facilitate the use of balanced inputs and dual
crossover networks. These features are unduplicated in any other stereo power amp on the market today.
A simplified functional diagram is printed on the top cover of the CS-400 ™ showing the four basic modes of operation. These diagrams also
appear in this manual for discussion purposes.
The CS-400 ™ is shipped from the factory with jumpers placed in the transformer accessory and crossover accessory sockets. These jumpers
are necessary if the low impedance input connectors (5) are to be used. As indicated in Diagram 1, the XLR type connectors (5) are wired in an
unbalanced configuration. (Pins 1 and 2 are ground, pin 3 is the input.) The unbalanced input configuration is acceptable whenever relatively short
cable runs are employed, or when the mixing system used has a transformer coupled output. This configuration will provide adequate hum and
