Integra ADM-20.4 - 2 Channel Amplifier Product Details Expand your A/V receiver’s audio distribution capabilities in the home theater and beyond with this powerful two-channel WRAT component, featuring auto power on and Three-Stage Inverted Darlington Circuitry. 75 Watts per Channel at 8 Ohms, 1 kHz, 0.08% THD, 2 Channels Driven, FTC WRAT (Wide Range Amplifier Technology) Three-Stage Inverted Darlington Circuitry to Reduce Distortion All Discrete Output Stage Circuitry Features Three-Stage Inverted Darlington Circuitry An important upgrade to the core WRAT concept is Integra’s Three-Stage InvertedDarlington Circuitry, a low negative feedback topology featuring a discrete tripletransistor array to cut distortion and boost current flow to the speakers. Discrete transistors also run cooler, extending the life of your output stage for more years of trouble-free service. All-Analog Circuitry Delivers Ultra-Clear Sound A standard integrated amplifier has the dual task of both processing and amplifying audio signals, and is therefore susceptible to interference from digital circuitry. As a dedicated power amp with all-analog circuitry, the ADM-20.4 is protected against digital interference. When partnered with a quality pre-processor, this unit offers all the benefits of pure analog amplification: a warm, musical, and full-bodied sound.
