Integra ADM-20.4 2-Channel Amplifier

Expand your AV 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.

An important upgrade to the core WRAT (Wide Range Amplifier Technology) concept is Integra’s 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.
