Features

Current feedback discrete power amp

This is equipped with a current feedback power amp that uses the
complimentary push-pull circuit used in the SM-11S1 Marantz Hi-Fi
power amp. This amp provides increased operating stability, and
high-speed, wide ranging high-density playback.
The current/voltage conversion amplifi cation section in the latter
part of the power amp is equipped with a Wilson current mirror
circuit that amplifi es to the high sound range with low distortion.

Improved instant power supply capability

The fi nal stage of the power amp is equipped with the same LAPT
(high effi ciency power transistor) that is installed in the SM-11S1
Marantz Hi-Fi power amp, providing improved instant power supply
capability.
The power section is equipped with a large-sized transformer.
As one of the essential parts of the power section, this unit is
equipped with Marantz original 33,000 μF / 71 V×2 (MM7055), and
15,000 μF / 71 V×2 (MM7025) block condensers, which have been
repeatedly tested for sound quality.
These improvements to the power supply capability provide a
powerful, presence-fi lled sound.

High sound quality design based on pure surround
philosophy

Equipped with a chimney-shaped heat sink to effi ciently process
the heat emitted from each channel amp , and exceptionally quiet
cooling fans. A high-sensitivity temperature sensor IC is used to
control the cooling fans, adjusting the rotation speed to match the
amount of heat generated by the amp.
These components provide the sound quality and low-noise you
would expect at a high-end theater.
In addition, this unit is designed for superb quality sound, and is
equipped with high quality components such as a high-end audio
condenser and fi lm condenser throughout.

BALANCED/UNBALANCED selecting function

Depending on the desired use, input for each channel can be
selected between BALANCED input and UNBALANCED input.

Remote Power Control

This unit is equipped with a remote power control function. When
a Marantz AV Pretuner AV8003 or AV7005 is connected to this
unit, this unit’s power can be switched ON/OFF together with the
AV8003 or AV7005 power supply.
Connection to the AV8003 or AV7005 is a ground fl oating
connection that prevents negative infl uences on sound quality as
far as possible.

Other Functions

Equipped with IR fl ash input that supports custom installations,
and DC trigger input and output terminals.

Cautions on handling

Before turning the power switch on

Check once again that all connections are correct and that there are
no problems with the connection cables.

• Power is supplied to some of the circuitry even when the unit is

set to the standby mode. When going on vacation or leaving home
for long periods of time, be sure to unplug the power cord from the
power outlet.

About condensation

If there is a major difference in temperature between the inside of
the unit and the surroundings, condensation (dew) may form on
the operating parts inside the unit, causing the unit not to operate
properly.
If this happens, let the unit sit for an hour or two with the power
turned off and wait until there is little difference in temperature
before using the unit.

Cautions on using mobile phones

Using a mobile phone near this unit may result in noise. If that
occurs, move the mobile phone away from this unit when it is in use.

Moving the unit

Turn off the power and unplug the power cord from the power
outlet. Next, disconnect the connection cables to other system units
before moving the unit.

About Care

• Wipe the cabinet and control panel clean with a soft cloth.
• Follow the instructions when using a chemical cleaner.
• Benzene, paint thinner or other organic solvents as well as

insecticide may cause material changes and discoloration if brought
into contact with the unit, and should therefore not be used.
