Architect's & Engineer's Specifications

The power amplifier shall have two channels. Each chan-

20Hz-20kHz, <0.1% THD+N

nel shall deliver a minimum of 720 watts at 8 ohms, 1200

720W

watts at 4 ohms and 1400 watts at 2 ohms; per channel,

1200W

both channels driven, 20Hz-20kHz, <0.1% THD+N. In

2250W

bridged mono mode, it shall deliver 2250 watts at 8 ohms,

1400W

and 2800 watts at 4 ohms, 20 Hz-20kHz, <0.1% THD+N.

2800W

The amplifier shall be rear-to-front tunnel-cooled, with a

105 CFM AC fan.

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 1.75V 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 37.5 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 XLR type, one female

per channel. Output connectors shall be 5-way binding

posts, two pair per channel. Octal sockets for optional

accessary 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 19" (483mm) wide, 5.25"

(133mm) high and 15" (381mm) deep. It shall weigh 80

lbs. (36.0kg) net. The amplifier shall be designated the

Crest Audio Model 8001.
