The power amplifier shall consist of 2 channels and deliver a
minimum of 800 watts per channel into a 70.7 volt “constant
voltage” line without the need for external step-up transform-
ers, both channels driven, 20Hz-20kHz, 0.1% THD+N.
A variable speed fan, with the ability to completely turn off
under appropriate ambient temperature conditions, shall pro-
vide air flow through the chassis from front to both sides.
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 levels
when amplifier is turned on, and circuitry for impedance
sensing and active clip limiting.
The amplifier shall include an energy saving feature which
shall automatically remove the output stage bias current when
the amplifier is in an idle condition.
The amplifier shall have a voltage gain of X40, or a voltage
gain of X20, or an input sensitivity of 0.775V, for rated
power, internally jumper-selectable. The hum and noise level
shall be greater than 105dB below rated output, “A” weight-
ed. 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 at rated power. The
amplifier shall operate at either 100, 120, 220, 230, or 240
volts, 50-60 Hz AC (configured at factory). Maximum current
draw at 120V shall be no greater than 30A, both channels dri-
ven continuously into a 70.7V line.
Front panel LED indicators shall include Active, Protect,
Signal Present, and ACL (Clip Limiting) LEDs for each chan-
nel. The power switch shall have three positions; one to per-
mit power up from a remote location, one to permit local
power up, and an ‘off’ position. The fan filter shall be front
panel mounted, with no tools required for removal.
The rear panel shall be configured with three openings or
bays which will accept plug-in modules used to accomplish
input signal processing, network control, remote sequential
turn-on/off and other related functions. The output module
shall be fitted with the following connectors: 5mm, 4-pin
Phoenix for sequential turn-on/off wiring, and an output bar-
rier strip with 0.438" (11mm) screw spacing, and 0.320"
(8mm) lug space. The input module shall be fitted with an
input barrier strip connector with 0.320" (8mm) screw spac-
ing, and 0.270" (7mm) lug space, and two individual channel
attenuators with removable knobs.
A user re-settable AC mains circuit breaker and AC mains
cord with 30 ampere twist-lock plug shall be mounted on the
rear chassis.
The packaging of the amplifier shall allow for standard rack
mounting without requiring space between similar units.
Dimensions shall be 19" (483mm) wide, 7" (178mm) high and
17.13" (435mm) deep. It shall weigh 70.65 lbs. (32.08 kg) net.
The amplifier shall be designated the Crest Audio model
CKV1600.
