welcome
Congratulations on your purchase of a new CD Series professional power amplifier and thank you for your confidence in Crest Audio products.You are among the growing 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 befor e installing and operating the amplifier .The Crest
Audio CD Series amplifiers are designed for high operating efficiency and accurate sonic perf ormance acr oss the full
audio bandwidth,even under stressful conditions.
The Crest Audio CD series amplifiers utilize Class D amplifier technology which greatly improves the efficiency of
the amplifier and reduces the power demand from the mains supply.The CD amplifier incorporates a linear power
supply design and are built to uncompromising standards.This, combined with major advances in amplifier technology provides for extreme reliability and sonic accuracy for which Crest products are renown.
linear-toroid power supply
A traditional linear power supply is used in the CD Series.Because of the amplifier section’s efficiency,(approx
80%) the transformer does not need to be as big or as heavy.This gives the CD Series an advantage in delivering more power in a more compact package.
The efficiency of the output stage also gives the power supply the ability to handle hea vy-duty cycles without
compromising sonic integrity.
In order to maintain strict quality assurance standards,all Crest Audio power amplifiers are built in our state-of-theart USA manufacturing facility. Internal components are the finest available and key sub-assemblies are pre-tested
before final assembly. Each amplifier is “burned in” and thoroughly tested (using precision audio test equipment)
before shipping.In addition,all CD Series amplifiers incorporate Crest’s exclusive TourClass
®
protection features to
safeguard both internal circuitry and connected loudspeakers.
This proven combination of advanced design,quality construction and comprehensive circuit pr otection is your guar-
antee of fail-safe reliability. You can depend on consistent,stable performance even when your CD Series amplifier
is subjected to punishing extremes in the most demanding fixed or mobile sound reinforcement applications.

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 carrier’s 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.
mounting
All CD Series amplifiers mount in standard 19-inch racks and occup y tw o rack spaces.
Four front-panel mounting holes are provided on each amplifier. Rear mounting ears
give additional support and use of rear supports is highly recommended in all mobile
and touring sound systems.Handles are available as an option (P/N:C32000010).

installation
Make certain that there
is enough space around
the front and rear of the
amplifier to allow the
heated air to escape.
When mounting 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 stan-
dard-rack-space opening
for every four amps.
a
cooling and ventilation
CD 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 cooling fins and then
exhausts through the front panel vent.
Heat sink temperature is monitored and controls the variable speed fan. Fan speed
increases only as required, keeping fan noise to a minimum.
Keep this unit 8” from any combustible surface on all sides.
If the heat sink surpasses its maximum allowed temperature , the thermal protection
circuit will activate and open the output relays allowing the amplifier to cool to a safe
temperature. Normal operation will resume once the amplifier cools to a safe level.
Thermal protect activation only occurs under extreme thermal conditions and is not
part of normal operation.
powering
Unless otherwise specified when ordered,CD amplifiers are supplied factory set to
following voltage options :
Option 1 US domestic nominal 120Vac 60Hz for rated power output
(safe operating range 100 - 132Vac )
Option 2 export models nominal 230Vac 50Hz for rated power output
(safe operating range 200 - 253Vac )
maintenance
On some CD amplifier models the fan is supplied with a removable f oam filter.This filter should be cleaned periodically with compressed air.
If the amplifier is used in an extremely dusty or smoky environment ,the unit should
be periodically blown free ( using compr essed air ) of an y for eign matter that ma y ha ve
built up inside the unit.
Users will not need to make an y adjustments to the amplifier during its lifetime.There
are no user-serviceable parts or adjustments that require opening the amplifier.
