Integra ADM-20.4 Stereo Power Amplifier

Extend your stereo setup to additional zones

The Integra ADM-20.4 has plenty of power — 75 watts per channel into an 8-ohm load — to be the main amplifier in your home stereo system. If you choose to expand that system into multiple zones, it's ready for that, too. A stereo RCA output lets you daisy-chain additional amps to bring two-channel sound to one or more rooms throughout your home.

Multiple power-up options

Ordinarily, you'd turn on your main amplifier with a remote control or go the old-fashioned route and manually push the button on the front of the chassis. In a multi-zone system, it's convenient to have some automatic turn-on options, which the ADM-20.4 provides. A switch on the back of the unit lets you choose — daisy-chained units can power up when the first amp comes on (voltage trigger), or they can wait until music starts to play (signal sensing).
