Operating Precautions
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 CS
®
Series warranty. See the Connecting Power
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.
Although the CS 3000/4000/4080 HZ amplifiers have RampUp
circuitry, which raises the signal level gradually after
the output relay closes, it is always a good idea to have the gain controls turned down during power-up 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.
Cable resistance robs amplifier power in two ways: power lost directly to resistance (I
2
R loss) and by increasing the
impedance of the load presented to the amplifier, 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, 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
®
connectors. Pin
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
Note: Always turn off and disconnect the amplifier from mains voltage before making audio connections. As an extra
precaution, have the attenuators turned down while powering up.
