Marantz PREMIUM STEREO POWER AMPLIFIER

The new SM11S1 is powerful. Very powerful. That’s because it takes as much as possible from the highly acclaimed Reference Series MA9S2. The result? A powerful, highly dynamic stereo main amplifier, offering an open, transparent, and precision sound.

As you would expect, this current feedback technique amplifier can easily handle demanding Loudspeakers. For extreme set-ups, the bridge mode (BTL mode) can convert the stereo amplifier SM11S1 to a 400 W mono amplifier. The two-stage circuit construction (voltage amplification first to increase audio signal, buffer amplification second to ensure high current delivery) guarantees an excellent signal to noise ratio and the full control of any speaker. Thanks to the adjustable gain factor the SM11S1 can also upgrade the PM11S1 integrated amplifier, creating an excellent bi-amp system set up.

Switching on/off can be remote controlled via a DC trigger from SC11S1 or other sources. Prepare to be exhilarated to a scintillating audio experience with crystal clear transparency
