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.

Left 0.2 m

(7-7/8 in) or more

Above 0.2 m

(7-7/8 in) or more

Right 0.2 m

(7-7/8 in) or more

Rear 0.2 m (7-7/8 in) or more

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.
