Multiplex 1100 power amplifier
The power amplifier shall have two channels.
Each channel shall deliver a minimum of
300
W
at 8
Ω
, 550
W
at 4
Ω
, 20
Hz
–20
kHz
,
<0.1%

. In bridged-mono mode, it shall
deliver 1000
W
at 8
Ω
, 20
Hz
–20
kHz
, <0.1%
THD+N
. The amplifier shall be front-to-side tun-
nel-cooled, with one 110
CFM AC
fans.
The amplifier shall have circuitry to protect itself
and the speaker load from output short circuits,
DC
voltage on outputs, and thermal overload.
The amplifier shall include circuitry to gradually
increase gain to attenuator setting levels when
the amplifier is turned on, and circuitry for
impedance sensing and clip limiting.
The amplifier shall have a voltage gain of
X
46.6 with an input sensitivity of 1.0
V,
for
rated power at 8
Ω
. The hum and noise level
shall be greater than 105
dB
below rated out-
put, A-weighted.
SMPTE IMD
shall be less than
0.1%, rated power at 8
Ω
. The amplifier shall
have a class AB output. The frequency
response shall be greater than 20
Hz
–20
kHz
,
+0/-0.3
dB (1W/8Ω)
.
The amplifier shall operate at 100–240
VAC
,
50–60
Hz
(configured at factory). Maximum
current draw shall not exceed 18
A
at 120
VAC
,
(circuit breaker limited), with both channels dri-
ving continuously into a 4
Ω
resistor.
The amplifier front-panel shall include
ACL
,
SIGNAL
,
PROTECT
LED
indicators for each chan-
nel and a combination power switch/magnet-
ic circuit breaker, and recessed and detented
gain pots.
Rear panel input connectors shall be TRS type,
one male and one female per channel. 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
13.33"
(339mm)
deep. It shall weigh 43
lbs.
(19.5kg)
net. The amplifier shall be designated
the Crest Audio Model Multiplex 1100.
