Power Amplifier
Congratulations on your purchase of the CS 6000/ CS 4000, a power amplifier 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 DDT™ (Distortion Detection Technique) circuitry ensures trouble-free operation into loads as low as 2
ohms. DDT protects drivers and ensures that sonic integrity is maintained, even in extreme overload conditions. The CS's high-efficiency design uses multi-rail class-H technology to produce high output power while reducing losses. Massive heat-sinks and a high
volume cooling fan maintains a lower overall operating temperature, resulting in longer output transistor life. For your safety, read
the important precautions section, as well as input, output and power connection instructions.
Although the CS 6000 amplifier is simple to operate and housed in an ultra-strong steel chassis, improper use can be dangerous.
This amplifier is very highpowered and can put out high voltages and sizable currents at frequencies up to 30 kHz. Always use safe
operating techniques when operating this amplifier.
Before you send signal through your amplifier, it is very important to ensure that the product has the proper AC line voltage
supplied. You can find the proper voltage for your amp printed next to the IEC line (power) cord on the rear panel of the
unit. Each product feature is numbered. Refer to the front panel diagram in this manual to locate the particular features next
to its number.
Please read this guide carefully to ensure your personal safety as well as the safety of your amplifier.
FEATURES:
• Distortion Detection Technique (DDT)
• Line voltage selector switch
• High volume cooling fan
• 100 Hz, 24dB/octave, Linkwitz-Riley Crossover
• Front panel LEDs: DDT, Signal,Thermal Protect and Power
• Switchable 2nd order 40Hz high pass filter

Equipment should be serviced by
qualified service personnel when:
A. The power supply cord or the plug has
been damaged.
B. The equipment has been exposed to
rain.
C. The equipment does not appear to
operate normally or exhibits a marked
change in performance.
D. The equipment has been dropped or
the enclosure damaged.
To obtain service:

Installation
Unpacking
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, 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.
Because of the complexity of the
design and the risk of electrical shock,
all repairs must be completed only by
qualified technical personnel.
Mounting
The CS 6000/ CS 4000 amplifier 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.
Connecting Power
The CS 6000/ CS 4000 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 back panel circuit
breaker. Consult the specifications in the
Specification section for figures on the
current that each amplifier will demand.
Make sure the mains voltage is correct
and is 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 warranty.
Always turn off and disconnect the amplifier from
mains voltage before making audio connections.
Also, as an extra precaution, turn the attenuators
down during power-up.
Cooling Requirements
The CS 6000/ CS 4000 amplifier uses a
forced-air cooling system to maintain
a low, consistent operating temperature. Air is drawn into the amplifier
by a fan on the rear panel that forces
air past the heatsink and amplifier
components before exiting the side
and front of the amplifier. If either
amplifier becomes too hot, sensing
circuits will reduce the amplifier
output signal until the amplifier sufficiently cools. The CS 6000/ CS 4000
utilizes one common heat sink and a
single fan, but retains the separate circuitry. NOTE: Maintain an adequate
air supply at the back of the amplifier
and enough space around the front 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 exhaust
air must flow without resistance.
If you are using racks with closed
backs, use fans on the rear rack panel
to pressurize the rack and ensure an
ample air supply.
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 warranty. See the Connecting Power section for more information on voltage
requirements.
Remember to have the gain controls turned down during power-up to prevent speaker damage if there is a high signal level at the
inputs. Whether you buy or make them, use good-quality connections, input cables and speaker cables, along with good soldering
technique, to ensure trouble-free operation. Most intermittent problems are caused by faulty cables.
Consult the Wire Gauge Chart to determine proper gauges for different load impedances and cable lengths. Remember that cable
resistance robs amplifier power in two ways: power lost directly to resistance (I2R loss), and by increasing the total load impedance,
thereby decreasing the power demanded of the amplifier. Also, make sure the mode switch is correctly set for the desired application.
See Sections on Stereo and Bridged Mono Mode for more information.
Make certain that there is enough space around the front and rear of the amplifier to allow the heated air to escape.
Suggestion: In racks with closed backs, allow at least one standard-rack-space opening for every mounted power amplifier.

AC POWER SWITCH(1)
Pressing the CS 6000/ CS 4000 power switch will alternately turn the amplifier on or off. Once the amplifier has completed its power
on sequence, the switch will light indicating it is on and operational.
INDICATORS
The CS 6000/ CS 4000 amplifier features signal and DDT indication for each channel along with amplifier power and thermal protection indicators.
THERMAL PROTECT LED (2)
If the amplifier temperature rises above its normal operating range, thermal protection circuitry reduces the output power on that
channel until it is safe to return to normal operation. If this happens repeatedly, either reduce the load on the amplifier (detach
one of the speakers), or supply additional cooling to the amplifier, such as a fan. When rack mounting, it is helpful to leave 1 RU
open above and below the amplifier to prevent heat buildup from adjacent units.
Signal Present and DDT (DISTORTION DETECTION TECHNIQUE) LED (3)
The channel LED will light green when a signal is present and red at the onset of clipping. If the LEDs are flashing red
quickly and intermittently, the channel is just at the clip threshold. A steady, bright red glow means the amp is clip limiting,
or reducing gain to prevent severely clipped waveforms from reaching the loudspeakers. See the Distortion Detection Technique section for more information.
INPUT ATTENUATORS (4)
Whenever possible, set the attenuators fully clockwise to maintain optimum system headroom. The input attenuator controls, located
at the front panel (one for channel A, one for channel B), adjust gain for their respective amplifier channels stereo mode. In bridged
mono mode, only the channel A attenuator is active. See the specifications at the end of this manual for standard voltage gain and
input sensitivity information.
When operating in Bridged
Mono mode, the channel A
attentuator controls the output.
The channel B attenuator is
inoperative..
See the section on Bridged Mono
operation for more information
and precautions.
