FEATURES
The PM-15S2 is a successor model for the PM-15S1, adopting
leading-edge technologies developed for the higher-grade
PM-11S2 model.
¶
HDAM-SA3 Module
The HDAM-SA3 is a key amplifier module for a current feedback
amplifier and is mounted on the voltage-current conversion
block, which is the most important part of an amplifier, for
further improved circuit stability and high-speed processing.
¶
Constant Current Feedback Phono Equalizer
The phono equalizer adopts a system that maintains the
current feedback at a constant level within the audible range,
and supports both the MC and MM cartridges. Thanks to
this system, extremely smooth sound over the entire band of
frequencies with less noise can be achieved.
¶
Linear Control Volume
This volume control amplifier is a combination of the MAS6116
from MAS and the inverse NF-type current feedback amplifier.
The amplifier section adopts a fully discrete design, combining
the HDAM-SA3 and the HDAM-SA2.
¶
CD Direct Input Buffer Amplifier
An input buffer amplifier that uses the HDAM-SA2 is mounted
directly after the input jacks in order to directly convey high-
quality Super Audio CD sound.
¶
V/I Servo Current Feedback Power Amplifier
To further improve the stability of the power amplifier, the
V/I Servo system has been developed. With this system,
fluctuations in the output offset voltage are converted into
currents and compensated in Current mode. Thus, the audio
quality and stability can be enhanced with this newly developed
V/I Servo system.
¶
F.C.B.S.
A Floating Control Bus System enables the user to connect
up to four PM-15S2 units for linked operation. A diversity of
applications, such as complete bi-amp with two units and 5.1
multichannel connections with three units, become available.
¶
Power Amplifier Direct Input
With this function, this unit serves as a power amplifier.
As this function can be turned ON or OFF with a button on
the front panel, this unit can be used as part of various audio-
visual systems.

EQUIPMENT MAINS WORKING
SETTING
Your Marantz product has been prepared to comply with the
household power and safety requirements that exist in your
area.
– Power requirements (U.S.A.) .......................AC 120V 60Hz
– Power requirements (Europe) ................AC 230V 50/60Hz
INAPPROPRIATE PLACES FOR
INSTALLATION
To keep your amplifier in perfect working order for the
longest possible time, avoid installing the unit in the following
locations.
• Wherever it will be exposed to direct sunlight
• Wherever it will be close to a heater or other heat-radiating
appliance
• Wherever the humidity is high or ventilation is poor
• Wherever it is very dusty
• Wherever it will be subject to vibration
• On top of a rickety stand or in an unstable location which is
tilted at an angle
• Near windows where there is a chance of exposure to rain,
etc.
• On top of an amplifier or other component which dissipates
a great deal of heat
To ensure proper heat dissipation, install the unit while leaving
clearances between the unit and wall or other components, as
shown in the figure below.

Do not place objects on top
• Refrain from placing any objects on top of the unit.
Do not touch hot areas, especially
around the “hot surface mark” during
and immediately after use.
During and immediately after use, this product is hot in areas
other than the controls and rear panel connection jacks. Do not
touch hot areas, especially around the “hot surface mark” and
the top panel. Contact with hot areas can cause burns.
