Power Amplifiers
Congratulations on your purchase of a Peavey CS Series power amplifier! Designed for years of reliable operation, CS Series
amplifiers offer the sonic superiority and unsurpassed reliability for which Peavey is famous in a rugged, compact unit.
Advanced technologies and extensive protection circuitry allow operation with greater efficiency, even under difficult loads and
power conditions. The exclusive DDT
™ (Distortion Detection Technique) circuit ensures trouble-free operation into loads as low
as 2 ohms, protects speakers and ensures sonic integrity even in extreme overload conditions. Peavey’s high-efficiency design
uses tunnel-cooled heat sinks and dual-speed DC fans for consistent lower overall operating temperature, resulting in longer
output transistor life.
Peavey CS Series amplifiers are simple to operate and housed in ultra-strong steel chassis, but improper use can be
dangerous. Some CS Series amplifiers are very high powered and can put out high voltages and sizable currents at frequencies
up to 30 kHz. Always use safe operating techniques with these amplifiers.
FOR YOUR SAFETY, READ THE IMPORTANT PRECAUTIONS SECTION, AS WELL AS INPUT, OUTPUT AND POWER
CONNECTION SECTIONS.
Unpacking
Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier immediately. Only the consignee
(the supplier from whom you purchased the amplifier) 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 or 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.
Mounting
CS Series amplifiers will mount in standard 19" 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.
Cooling Requirements
CS Series amplifiers use a forced-air cooling system to maintain a low, consistent operating temperature. Air is drawn
into the amplifier by fans on the back panel and courses through the cooling fins of the tunnel-configured channel
heat sinks, then exhausts through the front panel grilles. If either heat sink gets too hot, a sensing circuit will mute
the signal for that particular channel. It is important to have an air inlet at the back of the amplifier to allow cooling
air to enter. If the amp is rack mounted, do not use doors or covers on the back of the rack, as the intake air must
flow without resistance. Make sure that there is one (1) standard rack space opening for every three mounted power
amplifiers.
