Congratulations on your purchase of the CS 1200H power amplifier from Peavey—designed for years
of reliable, flawless operation under rigorous use. This amplifier offers the sonic superiority and
unsurpassed reliability for which Peavey is famous, while remaining surprisingly compact. Advanced
technology and extensive protection circuitry allow operation with greater efficiency into difficult
loads and power conditions. The D
DD DT T ™
(Distortion Detection) circuit ensures trouble-free operation
into loads as low as 2 Ohms. The Distortion Detection circuits protect drivers and ensure that sonic
integrity is maintained, even in extreme overload conditions. Peavey’s hi-efficiency design uses
patented Turbo-V cooling and variable speed DC fan. This cooling topology maintains a lower overall
operating temperature, resulting in longer output transistor life.
Although the Peavey CS 1200H amplifier is quite simple to operate and is housed in ultra-strong steel
chassis, improper use can be dangerous. This amplifier is very high-powered and can put out high
voltages and sizable currents at frequencies up to 30 kHz. Always use safe operating techniques
when operating this amplifier.

Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier immediately. Only
the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to
save the carton and all packing materials. Should you ever need to ship the unit back to Peavey
Electronics, one of its offices, service centers, or the supplier, use only the original factory packing. If
the shipping carton is unavailable, contact Peavey to obtain a replacement.

The CS 1200H amplifier will mount in standard 19-inch racks. Rear mounting ears are also provided for
additional support, which is recommended in non-permanent installations like mobile or touring
sound systems. Because of the cables and connectors on the rear panel, a right angle or offset
screwdriver or hex key will make it easier to fasten the rear mounting ears to the rails.

The CS 1200H amplifier uses a forced-air cooling system to maintain a low, even operating
temperature. Air is drawn into the amplifier by fans on the front panel, courses through the cooling
fins of the tunnel-configured channel heat sinks, and then exhausts through the rear panel slots. If
either heat sink gets too hot, its sensing circuit will open the output relay, disconnecting the load
from that particular channel. It is important to have an exhaust outlet at the back of the amplifier and
enough space around the sides of the amplifier to allow the cooling air to escape. If the amp is rack
mounted, do not use doors or covers on the front of the rack; the intake air must flow without
resistance. If you are using racks with closed backs, make sure that there is one (1) standard rack
space opening for every three mounted power amplifiers.
