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.

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.

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.

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.

PM-11S1 specifications

The Marantz PM-11S1 is a high-performance integrated amplifier that embodies the brand's commitment to delivering exceptional audio quality and craftsmanship. Launched as part of Marantz’s premium series, the PM-11S1 is designed to meet the demands of audiophiles and music enthusiasts alike.
