Crown Com-Tech 210 Power Amplifier w PIP2 High-Performance Vintage PRO audio

Description: CROWN CT-210 Vintage PRO Audiophile gear, working great!We pulled this amp when we upgraded a church sound system. It's never been pushed hard and always been in a air-conditioned, non-smoking environment.Info from Crown: Designed from the ground up exclusively for the professional sound contractor, Com-Tech® offers incredible features, flexibility, and the best long-term value in commercial audio today. The Com-Tech 10 Series amps offer the same features and performance of the original Com-Techs while delivering upgraded features to help make your job easier. In a profession where unplanned service calls quickly wipe out profits, Com-Tech 10 Series is designed to be the most reliable amplifier you can install. Specifications The following applies to 120-VAC, 60-Hz units in Stereo mode with 8-ohm loads and an input sensitivity of 26 Db gain unless otherwise specified. Specifications for units supplied outside the U.S.A. may vary slightly at different AC voltages and frequencies. Power Output Power *1 kHz **20 Hz-20 kHz Power Power 4-ohm Dual (per ch.) 150W 135W 8-0hm Dual (per ch.) 110W 105W 70-V Dual (per ch.) 110W 105W 8-ohm Bridge-Mono 300W 270W 70-V Parallel-Mono 210W 140-V Bridge-Mona 205W 200W *1 kHz Power: refers to maximum average power in watts at 1 kHz with 0.1% THD. **20 Hz–20 kHz Power: refers to maximum average in watts from 20 Hz to 20 kHz with 0.1% THD Load Impedance: Safe with all types of loads. With 8/4-ohm output, all Com-Techs are rated for 4 to 8 ohms in Dual mode, 8 to 16-ohms in Bridge-Mono mode, and 2 to 4 ohms in Parallel-Mono mode. With 70-volt output, rated loads vary among the different models for each dual/mono mode. Voltage Gain to 1 kHz, 8-ohm rated output: 90:1 ±12% or 39 dB ±1 dB gain at 0.775-volts (70-V) sensitivity. Required AC Mains: 60 Hz, 120 VAC onl. AC Line Current: Current, voltage and frequency requirements are provided on the unit’s back panel. At Idle: All units draw 35 watts or less when idle (in energy-saving mode). AC Line Connector: NEMA 5-15P plug is provided on 120 VAC, 60 Hz North American units. Plug illuminates when unit is powered. Performance Frequency Response: ±0.1 dB from 20 Hz to 20 kHz at 1 watt. Phase Response: ±10 degrees from 10 Hz to 20 kHz at 1 watt. Signal-to-Noise Ratio, A-weighted: Better than 105 dB below rated 1 kHz power. Total Harmonic Distortion (THD): 1 kHz rated power, 0.05% or less true THD. Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) Less than 0.05% from rated power to 35 dB below rated power at 8 ohms. Damping Factor: Greater than 1,000 from 10 Hz to 400 Hz. Controlled Slew Rate: (Slew rates are limited to useful levels for ultrasonic/RF protection.) Greater than 17 volts per microsecond. Controls Enable: A front-panel three-position switch used to select local, off or remote. Level: A 21-position detented back-panel rotary potentiometer for each channel used to control the input level. Sensitivity: A three-position switch located inside the PIP2 compartment used to select input sensitivity: 0.775 volts in 8/4-ohm mode or 0.775 volts in 70-volt mode for full rated output, or a 26-dB voltage gain. Dual/Mono: A three-position back-panel switch used to select Stereo, Bridge-Mono or Parallel-Mono mode. Reset: A back-panel push button used to reset the circuit breaker that protects the power supplies. Indicators Enable: An amber front-panel LED that shows the on/off status of the low-voltage power supply. Signal: A green front-panel LED for each channel that flashes to show amplifier output. IOC: An amber front-panel LED for each channel that flashes to show distortion if a channel’s output waveform differs from its input by 0.05% or more. ODEP: A green front-panel LED for each channel that shows thermal-dynamic energy reserve. Normally, each ODEP indicator is lit to show available reserve energy. In the rare event that a channel has no reserve, its indicator will dim in proportion to ODEP limiting. Input/Output Input Connectors: Balanced three-terminal barrier block connectors with test points are provided on the factory-installed PIP2-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. ConstructionSteel chassis with durable black powder-coat finish, front panel Lexan overlay, and specially-designed flow-through ventilation from front to side panels.
