welcome
Congratulations on your purchase of a new CPX Series power amplifier, and
thank you for your confidence in Crest Audio products. You are among the grow-
ing number of audio professionals who have made Crest Audio one of the world’s
leading suppliers of professional and commercial/industrial audio systems.
For your safety, please read the Important Precautions section before installing
and operating the amplifier. The Crest Audio CPX Series amplifiers are designed
for high operating efficiency and accurate sonic performance across the full audio
bandwidth, even under stressful conditions.
CPX series amplifiers feature a 2-way crossover and sub-sonic (low-cut) filter for
each channel. Crossover frequencies are fixed at 150 Hz, allowing subwoofers to
be driven at extremely high sound pressure levels, and the filters cut at 40 Hz to
prevent low-end rumble. Using proven technology gained through years of ampli-
fier design, this unit takes advantage of rugged TO-3P output devices mounted
on massive aluminum extrusions and dissipates heat via an extremely quiet and
effective 2-speed fan. CPX amplifiers employ mammoth toroidal power trans-
formers and offer impressive specifications and features not found on similarly
priced competitive units.
These amps are designed to drive a 2-ohm load per channel, thus achieving awe-
some performance levels into 4 ohms in BRIDGE mode. CPX amplifiers are
ruggedly constructed, rack-mountable pieces of gear with superb patching capa-
bility, allowing superior flexibility in application.
Front panel features include calibrated, detented gain (dB) controls and LED indi-
cators for power (PWR), signal presence (SIG), and GCL (Gain Comparator
Limiter) activation on each channel, as well as a rocker mains POWER switch.
The back panel contains an IEC connector for the mains power cord, a mains cir-
cuit breaker with reset, and the critical cooling fan opening. This opening should
have an adequate supply of cool air and should never be blocked or restricted.
Also on the back panel are the input and output sections, including an input bar-
rier strip for permanent installations. Each channel input section includes a combo
XLR / ¼" phone jack connector, THRU/LOW out and HIGH out ¼" jacks, and acti-
vation switches for the LOW CUT filter and crossover (150 Hz XOVER). Channel
output sections feature dual shock-proof binding posts and 4-conductor Speakon
connectors. An additional 4-conductor Speakon connector allows BRIDGE mode
output.

unpacking
Please inspect the amplifier carefully immediately after unpacking. If
you find any damage, notify your supplier/dealer immediately. Only the
shipper may file a damage claim with the carrier for damage incurred
during shipping. Be sure to save the carton and all packing materials
for the carriers inspection.
If the packing materials are in good condition, please save them.
If you ever need to ship the unit anywhere without mounting it in a rack,
you should take advantage of the original factory packing materials in
order to avoid unnecessary damage.

Make certain that there
is enough space
around the front and
rear of the amplifier to
allow the heated air to
escape. When mount-
ing in a rack, try to
avoid using doors or
covers on the front and
rear of the enclosure;
the exhaust air must
not be impeded
suggestion
In racks with closed
backs allow at least
one standard-rack-
space opening for
every four amps.
INSTALLATION
CPX professional power amplifiers are designed for durability in com-
mercial installations and provide the quality performance required in
studio and home applications. They are 2-rack-space units of 16" (406
mm) depth designed to mount in a standard 19" rack. Rear mounting
ears are provided for additional support. The minimum rack depth
required from the mounting surface is 17" (432 mm) to allow adequate
connector clearance.
cooling and ventilation
CPX amplifiers use a forced air cooling system to maintain a low, even
operating temperature.
Air is drawn in by a DC fan on the rear panel, flows through the cool-
ing fins and then exhausts through the front panel vent.
Heatsink temperature is monitored and controls the variable speed
fan. Fan speed increases only as required, keeping fan noise to a min-
imum.
If the heatsink surpasses it’s maximum allowed temperature, the ther-
mal protection circuit will activate and open the output relays allowing
the amplifier to cool to a safe temperature. Thermal protect activation
only occurs under extreme thermal conditions and is not part of nor-
mal operation.

Basic setup
Rack mount the amplifier in the location where it is to be used, remembering to
allow for adequate access and cooling space. Make all the connections to the
proper INPUT connectors on the desired channel. Select the proper mode con-
figuration (STEREO or BRIDGE). Connect speakers to the proper OUTPUT con-
nectors, reviewing carefully the impedance and phase considerations. With the
POWER switch OFF, connect the IEC cord to the amplifier and then to a suitable
electrical outlet to allow proper current draw. With both channel gain (dB) controls
at their fully counterclockwise (-8) settings, turn the POWER switch to ON, and
slowly raise the gain controls to desired settings. Please carefully review this
manual. It covers all this information in greater detail.
maintenance
CPX amplifiers require no routine maintenance other than checking the cooling
fans to make sure they’re unblocked and working.
If the amplifier is used in an extremely dusty or smoky environment , the unit
should be periodically “ blown free “ ( using compressed air ) of any foreign mat-
ter that may have built up inside the unit.
Users will not need to make any adjustments to the amplifier during it’s lifetime.
There are no user-serviceable parts or adjustments that require opening the
amplifier.

Channel Level attenuators
Two input attenuators adjust level for their respective amplifier channels. In
Bridged Mono and Parallel modes, the channel A attenuator controls overall
signal level (see rear panel mode switch description).
2
Power LEDs (PWR)
These indicators illuminate when the AC mains power is being supplied to the
amp and both channels are operational. If either channel experiences fault con-
ditions, exceeds safe operating temperature limits, or if the mains circuit break-
er trips; both channel power LEDs will be dark, indicating "shutdown". If the
BRIDGE mode is selected, the PWR indicator on channel B will remain dark as
a positive indication of this mode selection.
3
Signal activity LED’s (sig)
These indicators illuminate when the associated channel output signal level
exceeds 1 VRMS.
4
GCL Active LED’s
These indicators illuminate when GCL compression is taking place in the asso-
ciated channel. With the GCL ENABLE / DEFEAT switch on the back panel in
the ENABLE position, these LEDs indicate clipping is occurring in the corre-
sponding channel. The Crest GCL limiting system will be covered in greater
detail later in this manual.
5
Fan Outlet Grill
CPX Series amplifiers are cooled by a single rear-mounted fan. Cool air flows
over the heat sink and exhausts through the front grill. Make sure this outlet
remains clear to allow unrestricted airflow.
6
Power switch
This heavy-duty, rocker-type switch turns ON the mains power to the amplifier.
When the mains power is applied, there is a 3-second delay in activation of the
unit. This reduces/eliminates the turn-on transients associated with the system
equipment connected to the amplifier and protects loudspeakers.

Circuit breaker
There is one circuit BREAKER on the CPX amplifier. This breaker is provided
to limit current to the associated power transformer, and protect it from over-
heating and possible destruction due to fault conditions in the unit. The trip cur-
rent values have been carefully chosen to allow reasonable continuous power
output performance, while still protecting the power transformer. This breaker
should not trip unless there is a fault in the amplifier circuitry that causes exces-
sive mains current draw. However, abnormal conditions such as a short circuit
on either or both channels, or continuous operation at overload or clipping
(especially into 2-ohm loads per channel or 4-ohm bridge load) can cause the
breaker to trip. If this occurs, turn the POWER switch OFF and reset the break-
er, after waiting a brief period of time to allow the unit to cool down. Efforts
should be made to correct the cause of the overload if possible. When tripped,
the button on the BREAKER will be outward approximately ¼" and can be
reset by pushing inward and upward. A normal reset button is relatively flat. If
the breaker trips instantly each time you attempt to turn the unit on, it should be
taken to a qualified Crest Service Center for repair.
8
IEC Mains connector
This is a standard IEC power connector. An AC mains cord having the appro-
priate AC plug and ratings for the intended operating voltage is included in the
carton.
US Domestic AC Mains cord (not pictured)
The mains cord supplied with the unit is a heavy-duty, 3-conductor type with a
conventional 120 VAC plug with ground pin. It should be connected to an inde-
pendent circuit capable of continuously supporting at least 15 amps. This is
particularly critical for sustained high-power applications. If the outlet used does
not have a ground pin, a suitable grounding adapter should be used and the
third wire grounded properly.
Never break off the ground pin on any equipment. It is provided for your safety.
The use of extension cords should be avoided but, if necessary, always use a
3-wire type with at least a #14 AWG wire size. The use of lighter wire will
severely limit the power capability of this amplifier. Always use a qualified elec-
trician to install any new electrical equipment. To prevent the risk of shock or
fire hazard, always be sure that the amplifier and all associated equipment is
properly grounded.

Binding post outputs
Shockproof binding post speaker outputs are provided on the CPX amplifier.
For each channel, the outputs are in parallel and the speaker connection
cables can be terminated with banana plugs or stripped wires for use in the
binding post terminals, or can be connected using the Speakon outputs (9). For
sustained high-power applications, either outputs can be used; however, exer-
cise care to assure the correct speaker phasing. The red binding posts are the
signal outputs from each channel, and the black binding posts are chassis
ground. The red binding post should be connected to the positive inputs of the
associated loudspeakers. For BRIDGE mode operation, only the red binding
posts are used and the associated loudspeaker load is connected between the
two red posts.
WARNING…Regardless of what connections are used, the minimum parallel
speaker load should always be limited to 2 ohms per channel or 4 ohms
BRIDGE mode for any application. Operation at loads of 4 ohms per channel,
or 8 ohms BRIDGE mode, is more desirable for sustained operation applica-
tions because the amplifier will run much cooler at this loading. Operation
above 4 ohms per channel and even open-circuit conditions can always be
considered safe, but sustained operation at loads below 2 ohms could result in
temporary amplifier shut down due to the thermal limit circuitry.
10
Speakon outputs
CPX amplifiers utilize three 4-conductor Speakon connectors, one for each
channel and one for BRIDGE mode. Please refer to the BRIDGE MODE sec-
tion of this manual before attempting to use this mode. For each channel
Speakon, the same impedance rules apply as with the binding posts. Internally,
all the Speakons are wired in what is called the "high current" mode, with pins
1+ and 2+ in parallel, and pins 1- and 2- in parallel. For the CHANNEL A and
CHANNEL B Speakons, the respective channel output appears on pins 1+ and
2+. Pins 1- and 2- are chassis ground. For the BRIDGE Speakon, CHANNEL
A appears on pins 1+ and 2+, and CHANNEL B appears on pins 1- and 2-.
Always check the Speakon connector wiring carefully before using.
11
Mode switch
This switch is used to select STEREO or BRIDGE mode operation. It is a con-
ventional push-push type, requiring a small "tool" to activate. The IN position is
BRIDGE mode; the OUT position is STEREO mode. Exercise care when
selecting the BRIDGE mode. Accidental selection of this mode could damage
loudspeakers, particularly in bi-amped systems. Amplifier BRIDGE mode theo-
ry will be covered later in this manual.
