Expertly tuned by a Marantz Sound Master, the AMP 20 12-Channel 200W Power Amplifier from Marantz is designed to provide reference-level, home-theater audio. A total of 12 channels are available, each made to support a high-powered 200W at 8 ohms with no loss to fidelity. You have the choice of connecting each channel to an optional preamp, such as the Marantz AV 20, using unbalanced RCA or balanced 3-pin XLR to reduce noise. Speakers can be connected normally, or they can utilize BTL or bi-amp mode. The front of the power amp is sleek and sophisticated, with an analog porthole level meter and a metal front panel that has soft side lights that add a warm glow.

BTL Mode

BTL is also called Bridge Mode, which uses two channels on the AMP 20 to connect to a single speaker, combining them to increase the power to 400W at 8 ohms.

Bi-Amp Mode

In this mode, signals to your speaker’s high- and low-frequency drivers are split and driven independently, helping to reduce interference and improve overall sound quality.
