balanced. Nominally 10 k ohms, unbalanced.
Input Sensitivity: Settings include 0.775 volts
(8/4-ohm) or 0.775 volts (70-V) for standard 1
kHz power, or a 26-dB voltage gain.
Maximum Input Level: 9 Vrms.
Output Connectors: A back-panel barrier block
with two terminal connections for each output
channel.
Output Impedance: Less than 10 milliohms in
series with less than 2 microhenries.
DC Output Offset: Less than ±10 millivolts.
RSVP: A back-panel RJ-11 modular connector
interfaces with an R.S.V.P. unit to provide
remote control of amplifier power on/off
functions.
Output Signal;
Stereo: Unbalanced, two-channel.
Crown's Three-Year, No-Fault, Full Warranty
Crown offers a Three-Year, No-Fault, Full Warranty for every new Crown amplifier—an unsur-
passed industry standard. With this unprecedented No-Fault protection, your new Crown
amplifier is warranted to meet or exceed original specifications for the first three years of
ownership. During this time, if your amplifier fails, or does not perform to original specifica-
tions, it will be repaired or replaced at our expense. About the only things not covered by this
warranty are those losses normally covered by insurance and those caused by intentional
abuse. And the coverage is transferable, should you sell your amplifier.
See your authorized Crown dealer for full warranty disclosure and details. For customers
outside of the USA, please contact your authorized Crown distributor for warranty information
or call 219-294-8200.
Bridge-Mono: Balanced, single-channel.
Channel 1 controls are active; Channel 2
controls should be turned down.
Parallel-Mono: Unbalanced, single-channel.
Channel 1 controls are active; Channel 2 is
bypassed.
Protection
Com-Tech amplifiers are protected against
shorted, open or mismatched loads; over-
loaded power supplies; excessive temperature;
chain destruction phenomena; input overload
damage; and high-frequency blowups. They
also protect loudspeakers from input/output
DC and turn-on/turn-off transients.
If unreasonable operating conditions occur, the
patented ODEP circuitry will proportionally
limit the drive level to protect the output
transistor stages, particularly in the case of
elevated temperature. Transformer overheating
will result in a temporary shutdown of both
channels; the transformer will automatically
resets itself when it has cooled to a safe
temperature. Controlled slew rate voltage
amplifiers protect against RF burnouts. And
input overload protection is provided by
CT-810
current-limiting resistance at the input.
Turn On: The four second turn-on delay
prevents dangerous turn-on transients. "Soft
start" circuitry provides low inrush so power
sequencers are rarely needed with multiple
units.
Accessories:
Crown PIP and PIP2 modules
including IQ-PIP modules; R.S.V.P.
Construction
Steel chassis with durable black powder-coat
finish, front panel Lexan overlay, and specially-
designed flow-through ventilation from front to
side panels.
Cooling: Internal heat exchangers with on-
demand, forced-air cooling.
Dimensions: 19-inch (48.3-cm) standard rack
mount width (EIA RS-310-B), 5.25-inch (13.3-
cm) height, 16-inch (40.6-cm) depth behind
mounting surface and 0.25 inches (0.6 cm) in
front of mounting surface.
Approximate Weight: Center of gravity is 6
inches (15.2 cm) behind the front mounting
surface. 47 pounds, 4 ounces (21.5 kg) net; 50
pounds, 8 ounces (22.9 kg) shipping weight.
