Integra ADM-20.4 2-Channel Amplifier

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,  a low negative feedback topology featuring a discrete triple transistor 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.

High Output Power Supply

DTS Play-Fi is the most widely adopted Whole Home Audio Technology in the marketplace- it puts you in complete control of your Music and allows you to effortlessly stream from your smartphone, tablet, or PC to DTS Play-Fi speakers and devices throughout the home. Easy to set-up, easy to expand, and easy to enjoy- DTS Play-Fi and Integra- a smart solution.
