SM-11S1
Stereo Power Amplifier
“Music is what feelings sound like.”

Many early Marantz power amplifiers produced comparatively modest
power. In that light, the SM-11S1 – with its 110 watt per channel power
rating – holds to this tradition. But Marantz tradition also mandates
innovation. And so the SM-11S1’s output doubles to 220 continuous
watts per channel when delivering power to low impedance speakers.
A “bridging” circuit lets you configure the SM-11S1 as a monaural amplifier
delivering 420 watts. In any mode, the SM-11S1 generates truly exception-
al control and delineation of the most complex sources.
But brute force without finesse serves no real purpose for the sonically
sophisticated. To that end, Marantz engineered many new techniques. At
the circuit board level, precise signal path positioning minimizes channel
interference for superior ambience reproduction and soundstaging.
The SM-11S1 also boasts the newest SA3 version of Marantz’s Hyper
Dynamic Amplifier Module (HDAM®) technology so it instantaneously
responds to any signal.
And the SM-11S1, as do all Marantz Reference
components, resists the kind of destructive interaction with loudspeakers
that can degrade audible performance.
The high-current power supply boasts a toroidal transformer fully as
large as that used in our flagship MA-9S2 monaural power amplifier.
Configured for stereo use, this transformer feeds innovative power supply
circuits that allow the SM-11S1 to perform optimally under even the most
demanding conditions.
Of course, the SM-11S1’s high quality parts – even the precision WBT
speaker cable terminals – were chosen only after extensive listening tests to
determine their positive contributions to overall sound quality.
The SM-11S1 benefits from more easily observed qualities also.
It accepts balanced XLR inputs and easily switches between
stereo and bridged-mono modes.
A remote power turn-on
circuit lets you activate the amplifier from a preamplifier or
surround processor. And the front panel digital power meter
monitors output with magnetic sensors that do not interfere
with the audio signal.
The subtly-curved front panel echoes the SM-11S1’s internal
sophistication with a substantial yet décor-conscious design
equally at home in a custom cabinet or on an open shelf.
Performance. Design. Appearance. The SM-11S1 is a Reference
in every way.
and our demanding love of it.
