Crown COM-TECH 810 Power Amplifier for sale in Saint Anne, IL
CT-810 Power 4-ohm Dual (per ch.) 490W 305W 8-ohm Dual (per ch.) 460W 70-V Dual (per ch.) 975W 8-ohm Bridge-Mono 915W 70-V Parallel-Mono 920W 140-V Bridge-Mono *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 power 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; 20:1 ±3% or 26 dB ±0.25 dB gain at the maximum level setting. C O M - T E C H Features o Unique power supply allows channels to be independently operated in either 70-V or 8/4- ohm mode. o Remote feature allows amplifier to be turned on and off from a remote location by adding an optional R.S.V.P. accessory. o Crown's Grounded Bridge(TM) design delivers large voltage swings without using easily stressed output-transistor configurations like conventional amplifiers. The results are lower distortion and superior reliability. o Patented ODEP Protection) circuitry compensates for over- heating and overload to keep the amplifier working when others would fail. 64:1 ±12% or 35 dB ±1 dB gain at 0.775-volt (8/4-ohm) sensitivity; Voltage Gain to 1 kHz, 70-V rated output; 90:1 ±12% or 39 dB ±1 dB gain at 0.775-volt (70-V) sensitivity. Required AC Mains: 50/60 Hz-, 100-, 120-, 220-, 240-VAC (±10%) units are available. North American units are 60 Hz, 120 VAC only. AC Line Current; 20 Hz-20 kHz Current, voltage and frequency requirements Power are provided on the unit's back panel. At Idle: All units draw 35 watts or less when 460W idle (in energy-saving mode). 295W AC Line Connector: NEMA 5-15P plug is provided on 120-VAC, 60-Hz North American 455W units. Plug illuminates when unit is powered. 935W Performance Frequency Response: ±0.1 dB from 20 Hz to 20 kHz at 1 watt. 905W
