CS® 1400/2000
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.
®
Series warranty. See the Connecting Power
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.

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.
