Architect's & Engineer's Specifications
20Hz-20kHz, <0.05% THD+N
The power amplifier shall have two channels. Each chan-
550W
nel shall deliver a minimum of 550 watts at 8 ohms, 715
715W
watts at 4 ohms and 850 watts at 2 ohms; per channel, both
1510W
channels driven, 20Hz-20kHz, <0.05% THD+N. In
850W
bridged mono mode, it shall deliver a 1510 watts at 8
1600W
ohms, and 1600 watts at 4 ohms, 20 Hz-20kHz, <0.05%
THD+N.
The amplifier shall be rear-to-front tunnel-cooled, with two
variable-speed DC fans.
The amplifier shall have circuitry to protect itself and the
speaker load from output short circuits, DC voltage on out-
puts, and thermal overload. The amplifier shall include cir-
cuitry to gradually increase gain to attenuator setting lev-
els when the amplifier is turned on, and circuitry for
impedance sensing and clip limiting.
The amplifier shall have a voltage gain of X40 with an
input sensitivity of 1.4V for rated power at 4 ohms. The
hum and noise level shall be greater than 100 dB below
rated output, "A" weighted. SMPTE IMD shall be less
than 0.1%, rated power at 8Ω, 60Hz &7kHz. The amplifier
shall have a class H output stage with a modulated power
supply. The frequency response shall be greater than
20Hz-20kHz, +0/-0.3dB (1W/8Ω).
The amplifier shall operate at 100-240V, 50-60 Hz AC
(configured at factory). Maximum current draw shall not
exceed 21 amperes at 120VAC, (circuit breaker limited),
with both channels driving continuously into a 4 ohm resis-
tor.
The amplifier front panel shall include Active, Temp/DC,
Signal Present and Clip/Limit LED indicators for each
channel, a combination power switch/magnetic circuit
breaker and recessed and detented gain pots.
Rear panel input connectors shall be actively balanced and
have female XLR-type, 3-pin connectors (pin 3+). Output
connectors shall be 5-way output binding posts. Octal
sockets for optional accessory modules and a
signal/ground lift jumper shall be provided.
A rear-panel 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. Dimensions shall be 3.5" (89mm) high x 19"
(483mm) wide x 15" (381mm) deep. It shall weigh 52.0 lbs.
(23.6kg) net. The amplifier shall be designated the Crest
Audio Model 7001.
