9
The Crest Audio CA9 professional power amplier is designed to achieve unsurpassed sonic performance and long-term reli-
ability— even when operating under extreme stress—in touring or xed installation applications. Absolute sonic accuracy is the
hallmark of every Crest amplier. Bass is solid and dened to the limits of audibility, with ample current reserves delivered by
an “over-engineered” power supply and advanced Class H circuitry. Wide-bandwidth output devices assure detailed, transparent
high frequency response. And, thanks to Crest’s exclusive IGM circuit, the CA9 will drive 2 ohm loads safely without compro-
mise in performance.
Construction and Quality Control
The CA9 is built exclusively in Crest’s own USA manufacturing facility, with internal components selected for premium quality
and proven durability. Each modular subassembly is pre-tested, and the assembled CA9 receives a rigorous “hot room” burn-in
before thorough nal checkout on precision test equipment.
CA 9 Features
• Crest’s legendary “overbuilt” power supply
• Toroidal power transformer
• Latest generation of high-speed, wide-bandwidth output devices
• Twin tunnel cooling with back-to-front air ow

Architect’s & Engineer’s Specifications
The power amplifier shall have two channels. At 8 ohms, 20Hz
- 20kHz, 0.1% THD, it shall deliver a minimum of 150 watts
per channel. At 4 ohms, 20Hz - 20kHz, 0.1% THD, it shall
deliver a minimum of 200 watts per channel. In bridged mono
mode with an 8 ohm load, 20Hz - 20kHz, 0.1% THD, it shall
deliver a minimum of 450 watts.
The amplifier shall have circuitry to protect itself from output
short circuits, thermal overload or other adverse load condi-
tions. The amplifier shall protect speaker loads from DC volt-
age on outputs. The amplifier shall have active clip limiting
and impedance sensing circuitry. Output relays shall protect
the speakers from amplifier failure.
Two rear panel mounted variable speed DC fans (filters
detachable without tools) shall provide back to front air flow
through the chassis.
Each channel shall have a standard (factory-set) input sensitiv-
ity of 0.775 Volts, and shall be fitted with an internal jumper
which allows the gain to be altered to X20 or X40. The hum
and noise level shall be 105 dB below rated output, “A”
weighted. SMPTE IMD shall be less than 0.01% at rated
power, 60Hz and 7kHz. The amplifier shall have a class AB
output stage. The frequency response shall be 20Hz-20kHz,
+0, -0.3dB (1W/8Ω).
The amplifier will operate at 100V-240V, 50-60 Hz AC (config-
ured at factory). Maximum current draw shall not exceed 9
amperes at 120VAC (limited by front panel breaker for bench
tests).
Front panel indicators shall include Active, Protect, Signal,
and Clip LED’s for each channel. Front panel attenuators
shall be recessed and detented.
Rear panel input connectors shall be female TRS and XLR
type, internally dealer-configurable for pin 2 (factory setting)
or pin 3 positive. Output terminations shall be 5-way output
binding posts or Speakon output connectors (market depen-
dent). A ground lift switch and a Stereo/Parallel/Bridged Mono
mode operation switch shall be provided.
A rear-panel IEC AC mains socket (with power cord) or single
AC mains cord having an appropriate AC plug for the intended
operating voltage shall be provided (market dependent).
The packaging of the amplifier shall allow for standard rack
mounting without requiring space between similar units.
Optional rack mount handles will be available. Dimensions
shall be 19" (483mm) wide, 3.5" (89mm) high and 18"
(457mm) deep. The amplifier shall weigh 33 lbs. (14.98 kg)
net, and shall be designated the Crest Audio model CA2.
