Architect’s & Engineer’s Specifications
The power amplifier shall have two channels. At 8 ohms, 20Hz
- 20kHz, 0.1% THD+N, it shall deliver a minimum of 350 watts
per channel. At 4 ohms, 20Hz - 20kHz, 0.1% THD+N, it shall
deliver a minimum of 500 watts per channel. In bridged mono
mode with an 8 ohm load, 20Hz - 20kHz, 0.1% THD+N, it
shall deliver a minimum of 1000 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 H out-
put 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 18
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. A ground lift switch and a Stereo/
Parallel/Bridged Mono mode operation switch shall be provid-
ed.
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" (8.9mm) high and 17.85"
(454mm) deep. The amplifier shall weigh 44.0 lbs. (19.98 kg.)
net, and shall be designated the Crest Audio model PL6001.
Power figures are watts per channel, both channels driven. Crest Audio reserves the right to make improvements in manufacturing or design which may affect specification.
