Architect’s & Engineer’s Specifications<br />
The power amplifier shall have two channels. At 8 ohms, 20Hz<br />
- 20kHz, 0.1% THD+N, it shall deliver a minimum of 350 watts<br />
per channel. At 4 ohms, 20Hz - 20kHz, 0.1% THD+N, it shall<br />
deliver a minimum of 500 watts per channel. In bridged mono<br />
mode with an 8 ohm load, 20Hz - 20kHz, 0.1% THD+N, it<br />
shall deliver a minimum of 1000 watts.<br />
The amplifier shall have circuitry to protect itself from output<br />
short circuits, thermal overload or other adverse load conditions.<br />
The amplifier shall protect speaker loads from DC voltage<br />
on outputs. The amplifier shall have active clip limiting<br />
and impedance sensing circuitry. Output relays shall protect<br />
the speakers from amplifier failure.<br />
Two rear panel mounted variable speed DC fans (filters<br />
detachable without tools) shall provide back to front air flow<br />
through the chassis.<br />
Each channel shall have a standard (factory-set) input sensitivity<br />
of 0.775 Volts, and shall be fitted with an internal jumper<br />
which allows the gain to be altered to X20 or X40. The hum<br />
and noise level shall be 105 dB below rated output, “A”<br />
weighted. SMPTE IMD shall be less than 0.01% at rated<br />
power, 60Hz and 7kHz. The amplifier shall have a class H output<br />
stage. The frequency response shall be 20Hz-20kHz, +0,<br />
-0.3dB (1W/8Ω).<br />
The amplifier will operate at 100V-240V, 50-60 Hz AC (configured<br />
at factory). Maximum current draw shall not exceed 18<br />
amperes at 120VAC (limited by front panel breaker for bench<br />
tests).<br />
Front panel indicators shall include Active, Protect, Signal,<br />
and Clip LED’s for each channel. Front panel attenuators<br />
shall be recessed and detented.<br />
Rear panel input connectors shall be female TRS and XLR<br />
type, internally dealer-configurable for pin 2 (factory setting)<br />
or pin 3 positive. Output terminations shall be 5-way output<br />
binding posts or Speakon output connectors (market dependent).<br />
A ground lift switch and a Stereo/Parallel/Bridged Mono<br />
mode operation switch shall be provided.<br />
A rear-panel IEC AC mains socket (with power cord) or single<br />
AC mains cord having an appropriate AC plug for the intended<br />
operating voltage shall be provided (market dependent).<br />
The packaging of the amplifier shall allow for standard rack<br />
mounting without requiring space between similar units.<br />
Optional rack mount handles will be available. Dimensions<br />
shall be 19" (483mm) wide, 3.5" (8.9mm) high and 18"<br />
(457mm) deep. The amplifier shall weigh 44.0 lbs. (19.98 kg.)<br />
net, and shall be designated the <strong>Crest</strong> <strong>Audio</strong> model CA6.<br />
