Input/Output
Input Connectors: Balanced three-terminal barrier block connectors with test points are provided on the factory-installedPIP2-BB module.
Input Impedance: Nominally 20 k ohms, 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.
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
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.

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.
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.
