The amplifier shall consist of two channels. Each channel shall deliver a mini-
mum of 300 watts into a 70 volt, 100 volt, or 4 ohm load, per channel, both
channels driven 40Hz - 20kHz. In bridged mode, the amplifier shall deliver 600
watts at 8 ohms, 40Hz - 20kHz. The amplifier shall be convection-cooled. It
shall have circuitry to protect itself and the speaker load from output short cir-
cuits, DC voltage on outputs, and thermal overload. It shall have RMS clip lim-
iting, Auto-Ramp™ signal control, and impedance sensing circuitry. Output relays shall protect the speak-
ers from any type of amplifier failure. The amplifier shall have a voltage gain of 40x with an input sensitiv-
ity of 0.87V for rated power at 70 volts. The hum and noise level shall be greater than 100 dB below rated
output, “A” weighted. SMPTE IND shall be less than 0.02% at rated power, 60Hz and 7kHz. The amplifier
shall have a class AB output stage, a bi-polar power supply and a combination power switch/magnetic cir-
cuit breaker. The frequency response shall be greater than 40Hz - 20kHz, +0, -.3dB at rated power. The
amplifier will operate at either 100, 120, 220, or 240 volts, 50-60 Hz AC (configured at factory). Maximum
current draw shall not exceed 13 amperes at 120VAC or 7 amperes at 240VAC (limited by front panel
breaker for bench tests), both channels driven continuously into a 4 ohm resistor. Front panel indicators
shall include Active, Temp/DC, Signal Present and Clip/Limit LED’s for each channel. Front panel gain
pots shall be recessed and detented. The inputs shall be actively balanced, with female XLR-type 3-pin
connectors (pin 3+) and barrier strips. Output connectors shall be barrier strips. Octal Sockets for optional
accessory modules and a signal ground lift jumper will be provided. The packaging of the amplifier shall
be modular and allow for standard rack mounting without requiring space between similar units.
Dimensions shall be 5.25" (13.33cm) high x 19" (48.26cm) wide x14" (35.56cm) deep. The amplifier shall
have a net weight of 54.5 lbs (24.74 kg). The amplifier shall be designated the Crest Audio Model CV301.

The amplifier shall consist of two channels. Each channel shall deliver a minimum
of 625 watts into a 70 volt or 8 ohm load, per channel, both channels driven 20Hz -
20kHz. In bridged mode, the amplifier shall deliver 1250 watts at 16 ohms, 20Hz -
20kHz. The amplifier shall be convection-cooled. It shall have circuitry to protect
itself and the speaker load from output short circuits, DC voltage on outputs, and
thermal overload. It shall have RMS clip limiting, Auto-Ramp™ signal control, and
impedance sensing circuitry. Output relays shall protect the speakers from any type of amplifier failure. The
amplifier shall have a voltage gain of 40x with an input sensitivity of 1.77V for rated power at 70 volts. The
hum and noise level shall be greater than 100 dB below rated output, “A” weighted. SMPTE IND shall be less
than 0.02% at rated power, 60Hz and 7kHz. The amplifier shall have a class H output stage, a bi-polar power
supply and a combination power switch/magnetic circuit breaker. The frequency response shall be greater than
20Hz - 20kHz, +0, -.3dB at rated power. The amplifier will operate at either 100, 120, 220, or 240 volts, 50-60
Hz AC (configured at factory). Maximum current draw shall be no greater than 20 amperes at 120VAC or 10
amperes at 240VAC (limited by front panel breaker for bench tests), both channels driven continuously into a
8 ohm resistor. Front panel indicators shall include Active, Temp/DC, Signal Present and Clip/Limit LED’s
for each channel. Front panel gain pots shall be recessed and detented. The inputs shall be actively balanced
and have female XLR-type, 3-pin connectors (pin 3+) and barrier strips. Output connectors shall be five-way
binding posts and barrier strips. Octal Sockets for optional accessory modules and a signal/ground lift jumper
shall be provided. The packaging of the amplifier shall be modular and allow for standard rack mounting with-
out requiring space between similar units. Dimensions shall be 5.25" (13.33cm) high x 19" (48.26cm) wide x
14" (35.56cm) deep. The amplifier shall have a net weight of 50.5 lbs (29.90 kg). The amplifier shall be desig-
nated the Crest Audio Model CV601.
