Unpacking
Connecting Power
Upon unpacking, inspect the ampli-
fier. 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 replace-
ment.
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 recom-
mended in non-permanent instal-
lations like mobile or touring sound
systems.
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.
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.
Installation
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 tempera-
ture. 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 suf-
ficiently cools. The CS 6000/ CS 4000
utilizes one common heat sink and a
single fan, but retains the separate cir-
cuitry. 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.
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.
