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
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.
™
(Distortion Detection Technique) circuit ensures trouble-free operation into loads as low
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.

Introduction
Operating Precautions
Make sure the mains voltage is correct and the same as that printed on the rear of the amplifier. Damage caused by
connecting the amplifier to improper AC voltage is not covered by any CS
section for more information on voltage requirements.
Note: Always turn off and disconnect the amplifier from mains voltage before making audio connections. Also, as an
extra precaution, have the attenuators turned down during power-up.
Before powering up, turn the attenuator controls down to prevent speaker damage if there is a high signal level at the
inputs. Always use high-quality input and speaker cables to ensure trouble-free operation. Most intermittent problems
are caused by faulty cables.

Consult the Wire Gauge Charts (page 9) to determine proper gauges for differing load impedances and cable lengths.
Remember that cable resistance robs amplifier power in two ways: power lost directly to resistance (I
lowering the total load impedance. Also make sure the mode switch is correctly set for the desired application. See
sections on Stereo, Parallel and Bridged Mono Operation for more information.
Connecting Inputs
Input connections are made via the three-pin XLR (pin 2+) or 6.3 mm plug “combi” connectors on the rear panel of the
amplifier. The inputs are actively balanced and the overload point is high enough to accept the maximum output level
of virtually any signal source.
Connecting Outputs
All models have two output (speaker) connections per channel. Cables can be connected with banana plugs, spade
lugs, or bare wire to the five-way binding posts. The preferred connection method is via the Speakon
connections are noted on the rear panel.
Connecting Power
CS Series amplifier power requirements are rated at 1/8 power (typical music conditions) and 1/3 power (extreme
music conditions). The maximum power current draw rating is limited only by the front panel circuit breaker. Consult
the specifications in the Appendices section for figures on the current that each amplifier will demand. Unless
otherwise specified when ordered, Peavey amplifiers shipped to customers are configured as follows:
North America - 120VAC/60Hz
Europe, Asia, Australia - 230/240VAC/60-50Hz
South America - 120VAC/60Hz or 240VAC/50Hz

Operation Modes
Stereo Operation
For stereo (dual channel) operation, turn the amplifier OFF and set the mode select switches on the back panel to the
out (extended) position. In this mode, both channels operate independently of each other, with their input attenuators
controlling their respective levels. Thus, a signal at channel A’s input produces an amplified signal at channel A’s
output, while a signal at channel B’s input produces an amplified signal at channel B’s output.
Bridged Mono Operation
Both amplifier channels can be bridged together to make a very powerful single-channel monaural amplifier. Use
extreme caution when operating in the bridged mode; potentially lethal voltage may be present at the output
terminals. To bridge the amplifier, depress the rear panel Bridge switch to the IN position. Direct the signal to channel
A’s input and connect the speakers across the hot outputs (the “+” binding posts) of channels A and B. Only channel
A’s input attenuator is active while in Bridge Mono mode.
Unlike the stereo mode, in which one side of each output is at ground, both sides are hot in bridged mode. Channel A’s
side is the same polarity as its input with the minimum nominal load impedance being 4 ohms (equivalent to driving
both channels at 2 ohms) in bridged mode. Driving bridged loads of less than 4 ohms will activate the DDT
(see Indicators section), resulting in a loss of power, and may also cause a thermal (overheating) overload.

Switches & Controls
AC Power Switch/Circuit Breaker (1)
The CS® Series amplifiers feature a combination AC switch/circuit breaker on the front panel. If the switch shuts off
during normal use, push it back to the ON position once. If the switch will not stay in the ON position, the amplifier
needs servicing.

Input Attenuators (2)
Whenever possible, set the attenuators fully clockwise to maintain optimum system headroom. The input attenuator
controls (one for channel A, one for channel B) located on the front panel attenuate signal level (decrease gain) for the
respective amplifier channels in all modes. See the specifications at the end of this manual for standard voltage gain
and input sensitivity information.
Bridge Select Switch (3)
The rear panel Bridge Select switch determines if the amplifier is in stereo (two channels) or in Bridged Mono mode.
Do not operate the Bridge Select switch with the amplifier powered on. See the sections on Stereo and Bridged Mono
mode for more information.

Defeat Switch (4)
DDT
For normal operation, the DDT circuit should remain operational by leaving the DDT Defeat Switch in the extended
position. This will prevent excessive distortion and potential speaker damage.

Indicators
CS® Series amplifiers feature three front panel LED indicators per channel: PWR (power), SIG (signal) and DDT™ (Distortion
Detection Technique). These LED indicators inform the user of each channel’s operating status and warn of possible abnormal
conditions.
PWR LED (1)
The Power LED indicates that the channel is operational. It illuminates under normal operation and remains on even
when the channel’s DDT circuit is activated.
SIG LED (2)
The Signal LED illuminates when its channel produces an output signal of greater than 1 volt RMS or 25 mV input
with a O dB attenuation of the front panel knobs. This is useful in determining whether a signal is reaching and being
amplified by the amplifier. If the Signal LED is illuminated but no sound is present, that means a signal is present at
the amplifier but a problem may exist after the amplifier, such as in the cables or speakers.
DDT LED (3)
A channel’s DDT LED will illuminate at the onset of clipping. If the LEDs are flashing quickly and intermittently, the
channel is just at the clip threshold, while a steady, bright glow means the amp is clip limiting, or reducing gain to
prevent severely clipped waveforms from reaching the speakers. See Distortion Detection Technique Limiting under
the Protection Features section for more information.

Protection Features
The Peavey CS Series incorporates several circuits to protect the amplifier and speakers under virtually any situation. Peavey
has made the amplifiers as foolproof as possible by making them immune to short and open circuits, mismatched loads,
DC voltage and overheating. If a channel goes into the DDT™ gain reduction mode, the DDT LED illuminates. The clipping
percentage or output power is instantly reduced. When a problem occurs that causes a channel to go into a protection mode,
the PWR (Power) LED for that channel will turn off. DC voltage on the output or excessive subsonic frequencies will cause the
triac crowbar circuit to activate to protect the speakers. If the amplifier overheats, the signal will be removed from the channel
that is at fault until the amplifier cools down, thus protecting the amplifier.
Distortion Detection Technique (DDT) Limiting
Any time a channel is driven into hard, continuous clipping, the DDT circuit will automatically reduce the channel gain
to a level just slightly into clipping, guarding the speakers against the damaging, high-power, continuous square
waves that may be produced. Situations that may activate the DDT circuit include uncontrolled feedback, oscillations,
an improper equipment setting or malfunction upstream from the amplifier. Normal program transients will not trigger
DDT; only steady, excessive clipping will cause the DDT LED to illuminate.
LFC Impedance Sensing
CS Series amplifiers feature innovative circuitry for safe operation into any load. When an amplifier senses a load that
overstresses the output stage, the Load Fault Correction circuit adjusts the channel gain to a safe level. Extreme load
fault under high power levels will cause the signal to be muted for the associated channel. This method of outputstage protection is far more effective than the standard limiting found on conventional power amplifiers. The LFC
circuit is sonically transparent in normal use and unobtrusive when activated.
Thermal Protection
The internal fans will keep the amplifier operating well within its intended temperature range under all normal
conditions. If a channel’s heat sink temperature reaches 85° C (which may indicate an obstructed air supply), that
channel will independently protect itself by muting its input signal and shut down until it has cooled. During this time,
the PWR LED will go out and the cooling fans will continue operating at high speed.
Short Circuit
If an output is shorted, the LFC and thermal circuits will automatically protect the amplifier. The LFC circuit senses
the short circuit as an extremely stressful load condition and attenuates the signal, protecting the channel’s output
transistors from over-current stress. If the short circuit remains, the channel will eventually thermally protect itself by
muting the input signal.
DC Voltage Protection
If an amplifier channel detects DC voltage or subsonic frequencies at its output terminals, the output triac crowbar
circuitry will activate immediately to prevent speaker damage.
Turn-On/Turn-Off Protection
Upon powering up, the amplifier stays in Protect mode, muting the input signal for approximately four seconds while
the power supplies charge and stabilize. Also, when power is removed, the input signals are muted so that no thumps
or pops are heard.

Speaker Protection
All loudspeakers have electrical, thermal and physical limits that must be observed to prevent damage or failure. Excessive
power, low frequencies applied to high frequency drivers, severely clipped waveforms and DC voltage can all be fatal to cone
and compression drivers. Peavey CS® Series amplifiers automatically protect speakers from DC voltages and subsonic signals.
If using an electronic crossover, be extremely careful that the low and mid bands are connected to the correct amplifiers and
drivers and not to those designed for a higher frequency band. An amplifier’s clipping point is its maximum peak output power,
and some of the higher powered Peavey CS Series amplifiers can deliver more power than many speakers can safely handle. Be
sure the peak power capability of the amplifier is not excessive for your speaker system. For more information, see the section
on Protection Features.
Fuses may also be used to limit power to speaker drivers, although as current-limiting rather than voltage-limiting devices, they
are an imperfect solution, and as the weakest links, they only limit once before needing replacement. Some poor-quality fuses
have a significant series resistance that could degrade the amplifier’s damping of the speaker’s motion and may even deterio
rate the system’s sound quality. If you elect to use fuses, check with the speaker manufacturer to determine the proper current
rating and time lag required.
-
Do not drive any low frequency speaker enclosure with frequencies lower than its own tuned frequency; the reduced acousti
cal damping could cause a ported speaker to bottom out even at moderate power. Consult the speaker system specifications to
determine its frequency limits.

Amplifier Maintenance and User Responsibility
A CS Series amplifier requires no routine maintenance and should not need internal adjustment during its lifetime. Your CS
Series amplifier is very powerful and can be potentially dangerous to loudspeakers and humans alike. It is your responsibility to read the Important Precautions section and to make sure that the amplifier is installed, wired and operated properly as
instructed in this manual. Many loudspeakers can be easily damaged or destroyed by overpowering, especially with the high
power available from a bridged amplifier. Read the Speaker Protection section and always be aware of the speaker’s continuous
and peak power capabilities.
