Amplifier Audio Research reference 110 For sale Power amplifier Audi? Research REFERENCE high definition.220 v. POWER OUTPUT110 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.3% at 110 watts, below .003% at 1 watt. Approximate actual power available at clipping: 120 watts (1 kHz) (Note that the actual RMS power output is dependent upon both line voltage and condition ie: if the power line has high distortion, the maximum power will be adversely affected, although a listening standpoint this is not very critical.) POWER BANDWIDTH( -3dB) 12Hz to 60kHz.FREQUENCY RESPONSE(-3dB at 1 watt) 0.6Hz to 90kHz. INPUT SENSITIVITY1.8V RMS BAL for rated output. (24dB Bal gain into 8 ohms.) INPUT IMPEDANCE300K ohms Balanced.OUTPUT TAPS4, 8 and 16 ohms OUTPUT REGULATIONApproximately 0.7dB 16 ohm load to open circuit OVERALL NEGATIVE FEEDBACK12dBDAMPING FACTORApproximately 12DISTORTION-SLEW RATE10 V/µsRISE TIME3.5 µsHUM & NOISELess than 0.2mV RMS -106dB below rated output (IHF weighted, input shorted). POWER SUPPLY ENERGY STORAGEApproximately 520 joules.POWER REQUIREMENTS105-125VAC 60Hz (210-250VAC 50Hz) 630 watts at rated output, 800 watts maximum, 410 watts at idle. For those confused by the variety of devices from AR, I will explain that only the REFERENCE series actually plays,all the rest just sound somehow.This machine plays!You could even say it sings!Yes, AR has its own sound and its own vision of the process, but if youve ever heard the right path with AR, you wont exchange it for any other.It is not for nothing that the company actually stood at the origins of Hi End, like McIntosh, Krell, etc. and still exists. In general, you need to select the right components for it at its level and you will get sound of such quality that I think audio happiness is guaranteed to you. The amplifier is in excellent condition, no breakdowns and has no problems and I am sure will not have any.
