Peavey CS 200X User Manual

the ground pin on the CS 200X. The use of extension cords should be avoided but, if necessary, always use a
3-wire type extension cord with at least a #16 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 equip-
ment. To prevent the risk of shock or fire hazard, always be sure that the amplifier is properly grounded.
INSTALLATION AND CONNECTION:
The Peavey CS 200X commercial series power amplifier is designed for durability in commercial installations
and the quality of performance required in studio and home applications. The unit is a standard rack-mount
configuration that stands l-7/8” high and is cooled by convective air. 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 200X should
be mounted in a standard 19” rack with at least one rack space between each amp in the stack. If multiple
CS 2OOXs are stacked on top of one another, the upper units will be heated by the lower units. An adequate
“COOL” air supply (air that is not preheated by other equipment) must be provided for each amplifier when
rack-mounted. 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 amp is severely overloaded or shorted, the unit’s thermal sensing system
may cause temporary shutdown of that particular channel. This is indicated by a loss of signal in that channel.
Depending upon available cooling air, operation should be restored in that channel relatively quickly. In any
event corrective action should be taken to determine the cause of the thermal shutdown. If the unit is not severely
overloaded or shorted, then 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 200X can be mounted in any configuration. It is desirable for,
if at all possible, the unit be located at the top of an equipment stack. This will prevent possible overheating of
any sensitive equipment by the hot air rising from the power amplifier. As a general rule, most home and studio
requirements should never cause a thermal shutdown of either channel; however, if it does, this may indicate that
you have not taken the necessary steps to provide adequate cooling. Remember, closed up in a cabinet, the
CS 200X will have severe cooling problems, even at low power levels. Again, inadvertent short circuit or sus-
tained overloaded usage could also cause temporary thermal shutdown.
BRIDGE MODE:
The bridge mode on stereo amplifiers is often misunderstood as to the actual operation and usage. In basic terms,
when a two channel amplifier is operated in the BRIDGE mode, it is converted into a single channel unit with a
POWER RATING equal to the sum of both channels’ power ratings at a LOAD RATING of twice that of the
single channel rating. In this case, the CS 200X is rated at 110 watts RMS per channel into 2 ohms with the
Impedance Selector switch set a 4 ohms. Thus, the BRIDGE RATING is 220 watts RMS into 4 ohms (minimum
load). Bridge mode operation is accomplished by placing the mode switch in the “BRIDGE” position to connect
the load between the RED binding posts of each channel and using channel A as the input channel. All channel B
input functions are defeated, and they serve no purpose in bridge mode.
70 VOLT DISTRIBUTION SYSTEMS:
A popular application for BRIDGE mode operation is to drive sound distribution systems in very large public
address applications. In this mode, the CS 200X can actually drive 70 volt systems directly without using very
expensive output transformers. The primary advantage of such an approach is cost. 70 volt distribution systems
are very common where large numbers of relatively small loudspeakers are used for BACKGROUND MUSIC
AND PAGING. Such systems require the use of 70 volt TRANSFORMERS at each loudspeaker. The CS 200X
is unique here because when the 16 ohm impedance setting is selected, the unit delivers exactly 70 volts in
