Peavey CS 800X - Power and Installation; Installation and Connection Overview

MAINS POWER SOURCE (120 V Products Only) (22)
The CS-800X is fitted with a single heavy duty #14 AWG 3 conductor line cord and a
conventional AC plug with a ground pin. It should be connected to an independent mains
circuit capable of supporting at least 15 AMPS continuously or greater. This is particularly
critical for sustained high power applications. If the socket used does not have a ground pin, a
suitable ground lift adaptor should be used and the third wire grounded properly. Never break
off the ground pin on the CS-800X. The use of extension cords should be avoided, but if
necessary, always use a three-wire type with at least a #14 AWG wire size. The use of
lighter wire will severely limit the power capability of this amplifier. Always use a qualified
electrician to install any necessary electrical equipment. To prevent the risk of shock or fire
hazard, always be sure that the amplifier is properly grounded.
INSTALLATION AND CONNECTION:
The Peavey CS-800X commercial series power amplifier is designed for durability in com¬
mercial installations and the quality of performance required in studio and home applications.
The unit is a standard rack-mount configuration, 5 1/4" high, and is cooled by an automatic
two-speed internal fan. All the input and output connections are on the back panel. The front
panel contains LED indicators for power and DDT activation, detented/calibrated sensitivity
controls, and a mains power switch.
INDUSTRIAL AND COMMERCIAL INSTALLATIONS
For commercial and other installations, where sustained high power operation is required, the
CS-800X should be mounted in a standard 19" rack. It is not necessary to leave rack space
between each amplifier in the stack, since the fan pulls air in from the rear and exhausts the
hot air out the front. An adequate “COOL” air supply must be provided for the amplifier
when rack-mounted. The internal fan must have a source of air that is not preheated by other
equipment. The amplifier will start up in “LOW SPEED” fan operation and will normally
stay at low speed operation unless sustained high power operating levels occur. Then, as the
amplifier “HEAT SINKS” heat up, the automatic thermal sensing circuitry will cause high
speed operation to occur. Depending upon signal conditions and amp loading, high speed fan
operation may continue, or it may cycle continuously between high and low. This situation is
quite normal. If cooling is inadequate due to preheated air, or a reduction of air flow^ occurs
due to blockage of the amplifier inlet/outlet ports, or if the amplifier is severely overloaded or
short circuited, then the amplifier thermal sensing system may cause temporary shutdown of
that particular channel. This is indicated by the channel power LED (on the front panel)
ceasing to illuminate. Depending upon available cooling air, operation should be restored in
that channel relatively quickly, and the power LED will be illuminated. In any event, correc¬
tive action should be taken to determine the cause of the thermal shutdown. If the amplifier
is not severely overloaded or shorted and air flow is normal in and out of the unit, steps
should be taken to provide a cooler environment for all the amplifiers. As a general rule, the
cooler electronic equipment is operated, the longer its useful service life.
STUDIO AND HOME INSTALLATION:
In most low to medium power applications, the CS-800X can be mounted in any configura¬
tion. It is desirable, if at all possible, that the unit be located at the top of an equipment stack.
