Congratulations on your purchase of the CS3000H power amplifier from Peavey—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

DDDDTT

™ (Distortion Detection) circuit ensures trouble-free operation
into loads as low as 2 oHms. The Distortion Detection circuits protect drivers and ensure that sonic
integrity is maintained, even in extreme overload conditions. Peavey’s high-efficiency design uses
tunnel-cooled heat sinks and variable speed DC fans. This cooling topology maintains a lower overall
operating temperature, resulting in longer output transistor life.

Although the Peavey CS3000H amplifier is quite simple to operate and is housed in ultra-strong steel
chassis, improper use can be dangerous. This amplifier is very high-powered and can put out high
voltages and sizable currents at frequencies up to 30 kHz. Always use safe operating techniques
when operating this amplifier.

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
Electronics, 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.

MMoouunnttiinngg

The CS3000H amplifier will mount in standard 19-inch 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.

CCoooolliinngg RReeqquuiirreemmeennttss

The CS3000H amplifier uses a forced-air cooling system to maintain a low, even operating
temperature. Air is drawn into the amplifier by fans on the front panel, courses through the cooling
fins of the tunnel-configured channel heat sinks, and then exhausts through the rear and side panel
slots. If either heat sink gets too hot, its sensing circuit will open the output relay, disconnecting the
load from that particular channel. It is important to have an exhaust outlet at the back of the amplifier
and enough space around the sides 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 intake air must flow without
resistance. If you are using racks with closed backs, make sure that there is one (1) standard rack
space opening for every three mounted power amplifiers.

Although the CS3000H amplifier has

RRaammppUUpp

™

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. 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 (below) 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 lowering the total load impedance. Also make sure the mode switch is
correctly set for the desired application. See Sections on

Input connections are made via the 3-pin XLR (pin 2+) or 6.3 mm plug “Combi” connectors on the
rear panel of the amplifier. The inputs are actively balanced. Pinout and polarity of connection
cables should be configured correctly (refer to the rear panel of the unit). The input overload
point is high enough to accept the maximum output level of virtually any signal source.

CCoonnnneeccttiinngg OOuuttppuuttss

All models have two output (speaker) connections per channel. Cables can be connected with
banana plugs, spade lugs, or bare wire to the 5-way binding posts. The preferred connection
method is via the Speakon connectors. Pin connections are noted on the rear panel of the unit.

CCoonnnneeccttiinngg PPoowweerr

The CS3000H 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 this manual for figures on the current
that this 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. Unless otherwise specified when ordered, Peavey
amplifiers shipped to customers are configured as follows:

North America: 120 VAC/60 Hz

Europe, Asia, Australia: 230/240 VAC/50 Hz

South America: 120 VAC/60 Hz or 240 VAC/50 Hz

SStteerreeoo

For stereo (dual channel) operation, turn the amplifier off and set the mode select switch to the
stereo 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.

PPaarraalllleell

For parallel (dual-channel/single input) operation, turn the amplifier off and set the mode switch
in the parallel position; both amplifier channels are then driven by the signal at Channel A’s
input. No jumper wires are needed. Output connections are the same as in the stereo mode. In
the parallel mode, only Channel A’s input is active; Channel B’s is out-of-circuit. Both input
attenuators remain active, allowing you to set different levels for each channel. Power and other
general performance specifications are the same as in the stereo mode.

BBrriiddggeedd MMoonnoo

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, set the rear panel mode
select switch to the bridge position. Apply the signal to Channel A’s input and connect the
speakers across the hot outputs (the “+” binding posts of Channels A and B).

Unlike the stereo and parallel modes, in which one side of each output is at ground, in the
bridged mode both sides are hot. Channel A’s side is the same polarity as the input. For proper
operation, both input attenuators must be in the same position. This keeps the load balanced
between the channel outputs. As in the parallel mode, only Channel A’s input is active. If an
output patch panel is used, all connections must be isolated from each other and from the panel.
The recommended minimum nominal load impedance in the bridged mode is 4 ohms (equivalent
to driving both channels at 2 ohms). Driving bridged loads of less than 4 ohms will activate the
DDT circuitry resulting in a loss of power, and may also cause a thermal overload.

The CS3000H amplifier has 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 it will not stay on, the amplifier
needs servicing.

IInnppuutt AAtttteennuuaattoorrss ((22))

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 at the front panel adjust gain
for their respective amplifier channels in all modes. See the specifications at the end of this manual
for standard voltage gain and input sensitivity information.

When operating in the bridged mode, both attenuators must be in the same position so the speaker
load will be equally shared between the channels. See the section on

SSIIGGNNAALL LLEEDD ((33))

This LED is at the bottom of the bar graph display and lights when its channel produces an output
signal of greater than 2 volts RMS or 50mV input with a 0 dB attenuation of the front panel knobs. It
is useful in determining whether a signal is reaching and being amplified by the amplifier. The 10­segment graphs indicate the level of signal present.

DDCC LLEEDD ((44))

The DC LED lights to indicate that the channel’s output relay is open, disconnecting the speaker(s)
when the amplifier senses a DC voltage or subsonic high level signal at its output.

TTEEMMPP LLEEDD ((55))

The Temp LED lights to indicate that the channel’s output relay is open, disconnecting the speaker(s)
due to an overheating condition. Once the channel temperature has returned to safe operating
conditions the LED will turn off and the speaker(s) will be reconnected.

The CS3000H is equipped with two independent‚ two-way crossovers adjustable from 40Hz to 300

these crossovers is selected by the MODE switch and connected to the corresponding amplifier
channel. Frequencies above the knob setting will be connected to the corresponding channel
when the MODE switch is in the HIGH PASS position. Frequencies below the knob setting will be
connected to the corresponding channel when the MODE switch is in the LOW PASS position. The
FULL RANGE position bypasses the crossover.

DDDDTT LLEEDD ((66))

A channel’s DDT LED will light at the onset of clipping. If the LED’s 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 reaching the loudspeakers.
See the Distortion Detection section for more information. During initial power up the DDT LED will
light indicating that the RampUp gain reduction circuitry is activated. This will prevent sudden
signal bursts when the speaker relays are closed.

AACCTTIIVVEE LLEEDD ((77))

The ACTIVE LED indicates that its channel’s output relay is closed and the channel is operational. It
lights under normal operation and remains on even when the channel is in Distortion Detection

secondary amplifier.

LLOOWW PPAASSSS OOUUTTPPUUTT CCoonnnneeccttoorr ((1144))

The LOW PASS OUTPUT connector allows patching the frequencies below the crossover knob setting to
a secondary amplifier. This output remains at low frequencies independent of the MODE switch setting.

PPrrootteeccttiioonn FFeeaattuurreess

The CS3000H incorporates several circuits to protect both itself and loudspeakers under virtually any
situation. Peavey has attempted to make the amplifier as foolproof as possible by making it immune to
short and open circuits, mismatched loads, DC voltage, and overheating. If a channel goes into the
Distortion Detection or DDT gain reduction mode, the speaker load remains connected, but clipping
percentage or output power are instantly reduced. When a problem occurs that causes a channel to go
into a protection mode, the TEMP LED or DC LED for that channel will glow. DC voltage on the output,
excessive subsonic frequencies, or thermal overload will cause the channel’s output relay to disconnect
the speaker load until the problem is corrected or the amplifier cools down.

DDiissttoorrttiioonn DDeetteeccttiioonn LLiimmiittiinngg

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, or an improper equipment setting or malfunction upstream
from the amplifier. On the CS3000H, normal program transients will not trigger DDT; only steady,
excessive clipping will. The DDT LED will glow brightly and continuously when limiting occurs.

LLFFCC IImmppeeddaannccee SSeennssiinngg

The CS3000H features innovative circuitry that allows safe operation into any load. When an amplifier
sees a load that overstresses the output stage, the Load Fault Correction circuit adjusts the channel
gain to a safe level. This method of output stage protection is far superior to conventional, brute force
type limiting found on other amplifiers. The LFC circuit is sonically transparent in normal use and
unobtrusive when activated.

TThheerrmmaall PPrrootteeccttiioonn

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 disconnecting its load and shutting down
until it has cooled. During this time, the channel’s TEMP LED will light. During this time, the ACTIVE LED
will go out, the Temp and DDT LEDs will stay lit and the cooling fans will stay running at high speed.

10

SShhoorrtt CCiirrccuuiitt

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 disconnecting the load.

DDCC VVoollttaaggee PPrrootteeccttiioonn

If an amplifier channel detects DC voltage or subsonic frequencies at its output terminals, its output
relay will immediately open to prevent loudspeaker damage. The channel’s DC LED will light.

TTuurrnn--OOnn//TTuurrnn--OOffff PPrrootteeccttiioonn

At power-up, the amplifier stays in the protect mode, with outputs disconnected, for approximately
four seconds while the power supplies charge and stabilize. While the output relays are open, the DDT
LEDs light. When power is removed, the speaker loads immediately disconnect so that no thumps or
pops are heard.

RRaammppUUpp™™SSiiggnnaall CCoonnttrrooll

Whenever amplifier powers up or comes out of a protect mode, the RampUp™ circuit activates. While
the speakers are disconnected, the RampUp™ circuit fully attenuates the signal. After the output
relay closes, the signal slowly and gradually raises up to its set level. The RampUp™ Signal Control
circuit has some important advantages over the conventional instant-on circuits:

If a signal is present during power-up (or when coming out of protect), the speakers are
spared a sudden, potentially damaging burst of audio power.

Because the gain is reduced until after the output relay closes, no arcing occurs at the
contacts, thereby extending their useful life.

SSppeeaakkeerr PPrrootteeccttiioonn

All loudspeakers have electrical, thermal and physical limits that must be observed to prevent
damage or failure. Too much power, low frequencies applied to high frequency drivers, severely
clipped waveforms, and DC voltage can all be fatal to cone and compression drivers. The Peavey
CS3000H amplifier automatically protects speakers from DC voltages and subsonic signals. For more
information, see the section on Protection Features. Mid- and high-frequency speakers, especially
compression drivers, are highly susceptible to damage from overpowering, clipped waveforms, or
frequencies below their rated pass band. Be extremely careful that the low and mid bands of an
electronic crossover are connected to the correct amplifiers and drivers and not accidentally
connected to those for a lower frequency band. The amplifier’s clipping point is its maximum peak
output power, and the high power Peavey CS3000H amplifier 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.

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 deteriorate 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 acoustical damping could cause a ported speaker to bottom out even at
moderate power. Consult the speaker system specifications to determine its frequency limits.

4. Double check all connections and make sure there are no exposed wires or connectors before
turning the amplifier on.

5. Make sure there are no frayed cables or wires and that all connections are tight and secure every
time before turning the amplifier on.

6. External wiring connected to these terminals requires instructions by an instructed
person or the use of ready-made leads or cords.

A CS3000H amplifier requires no other routine maintenance and should never need any internal
adjustment during its lifetime. Your CS3000H 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.
