Architects’ & Engineers’ Specifications:
The power amplifier shall consist of 2 chan-
nels. Each channel will deliver a minimum of
(280 / 400 / 560 / 800) watts at 8 ohms, (500 /
750 / 1000 / 1500) watts at 4 or 2 ohms, 1 kHz.
In bridged mono mode, it will deliver a mini-
mum of (1000 / 1500 / 2000 / 3000) watts at 8
or 4 ohms, 1 kHz. It shall weigh (30 / 35 / 38 /
41.4) lbs. The amplifier shall incorporate pro-
tection circuitry against output short circuits,
DC voltage on outputs, thermal overload and
load protection due to any form of amp failure.
It will include impedance sensing circuitry, and
RMS clip limiter and Auto-Ramp signal control.
The amplifier shall have a sensitivity of .775V
at the input, which will deliver full rated output
power at 4 ohms. Gain can be changed to x20
or x40. The hum and noise level shall be
greater than 100dB below rated output at 4
ohms, "A" weighted. The amplifier shall have a
class D output stage with a linear power sup-
ply. The frequency response shall be greater
than 20 Hz - 20 kHz, +/-1 dB, at full rated out-
put power @ 4 ohms, 1%THD. The amplifier
will operate at either 120 VAC, 60Hz (safe
operating range 100-132VAC) or at 230 VAC,
50Hz (safe operating range 200-253), voltage
selection determined at factory. Maximum cur-
rent draw at 120V shall be no greater then 15
A (CD3000), both channels driven continuous-
ly into 4 ohm load at 1/3 power. Front panel
indicators shall include LED indicators for
Protect, ACL / IGM (automatic clip limit), Signal
level, and Active status. Front panel attenua-
tors will be recessed and detented. Input con-
nectors shall be Neutrik Combo
™
connectors
featuring balanced inputs on female XLR and
1/4" TRS, and unbalanced inputs on 1/4” TS ,
one per channel. Output connectors shall be
5-way binding posts and Speakon, per chan-
nel. A switch shall enable the signal ground to
be lifted from the chassis. The packaging of the
amplifier shall allow for standard rack mounting
without requiring space between similar units
as long as rack is properly ventilated.
Dimensions main chassis shall be 17" wide
(front panel is 19" wide), 15.3" deep (16.55"
including rear rack ears), 3.5" high. The ampli-
fiers shall be designated the Crest Audio Model
CD1000, CD1500, CD2000, and CD3000.
