ENGLISH
The PM-11S1 is an integrated amplifier developed on the con-
cepts of Marantz’s SC-7S1 and MA-9S1 flagship amplifiers.
• HDAM  SA2
The HDAM  SA2 is an evolved version of the HDAM  SA incor-
porated into the SC-7S1 and MA-9S1. It drives the phono
amplifier, balance buffer, line buffer, volume amplifier, voltage
amplifier and power buffer that comprise the PM-11S1.
Input Amplifier
• Current Feedback Phono Equalizer
The phono equalizer of the PM-11S1 supports MC/MM car-
tridges and incorporates the first-ever current feedback circuit
used with a Marantz product. The newly designed circuitry
employs both Marantz’s previous HDAM
 and the newly de-
veloped HDAM  SA2.
• Current Feedback Balance Buffer
The PM-11S1 incorporates an HDAM  SA2-driven current feed-
back balance buffer that faithfully transfers signals from de-
vices of quality balanced output such as super audio CD play-
ers and D/A converters.
• Individual Input Buffer for Each Line
Input Jack
Each the CD, LINE 1, LINE 2, RECORDER 1 and RECORDER
2 input jack has its own input buffer built on HDAM
 SA2 tech-
nology. By providing each line with its own buffer amp, it is
possible to prevent interference between input sources and
thereby faithfully transfer signals from the input source.
Preamplifier
• Linear Control Volume
The PM-11S1 incorporates linear control volume that carry
forward the design concepts of the SC-7S1. In combination
with the WM8816 by Wolfson and the HDAM
 SA2, these lin-
ear control varistors improve S/N ratio, enabling smooth con-
trol in
±0.5 dB steps across a 0 - -100 dB range.
• Tone Control Amplifier
The PM-11S1 incorporates an adjustable jack-type tone con-
trol amplifier for controlling bass and treble in 2 dB steps across
a
±8 dB range. The left and right channels can be separately
adjusted from the remote controller.
FEATURES
Power Amplifier
• Dual Amplifier Structure
The PM-11S1 carries on the dual amplifier design concepts of
the MA-9S1 with separate voltage and power amplifiers. With
this dual amp structure, the power buffer powerfully drives the
speakers whereby shutting out the effects of return current
from the speakers. The voltage amplifier drives the power buffer
with ultra low distortion.
Power
• Choke Input Power Supply
The PM-11S1 incorporates a choke input power circuit built
with a high capacity smoothing capacitor in order to thoroughly
eliminate high frequency noise from the rectifier circuit and
external sources. It delivers a distortion-free power supply to
the input amplifier and preamplifier.
Functions
• Bi-Amp Mode
The complete bi-amp connection proposed by Marantz with
the SC-7S1 and MA-9S1 reproduces a sound environment
never before experienced. This same bi-amp connection has
been made possible with the PM-11S1. Two PM-11S1s are
connected by FCBS in a bi-amp mode that enables each to
work as a monaural integrated amplifier.
• Floating Control Bus System
A Floating Control Bus System (FCBS) enables the user to
connect up to four PM-11S1s, making possible a diversity of
applications with complete bi-amp and multiple channel con-
nections. Moreover, a ground loop is not formed between mul-
tiple connected PM-11S1s, therefore sound quality is not ad-
versely affected.
• Display
The PM-11S1 adopts an LCD to display input source and vol-
ume level. Compared to other types of display panels, an LCD
generates less drive noise and radiated noise, hence the ef-
fect on sound quality is minimal.
