All-discrete current-feedback amplifi er

Marantz’  proprietary  current-feedback  circuit,  using  discrete 
components, is adopted in the pre amplifi er and power amplifi er. 
It is a high-speed amplifi er using the latest technology developed 
for the higher-grade amplifi ers.

HDAM-SA3 Technology

The  V/I  converter  circuit,  which  is  the  key  block  of  the  current-
feedback  pre-amplifi er  and  power  amplifi er,  is  equivalent  to  the 
HDAM-SA3 ampmodule developed for such higher-grade models 
as the PM-11S2.

CD direct buffer amplifi er

An  input  buffer  amplifi er  exclusive  for  CD  is  mounted  near  the 
CD  input  jacks.  This  is  a  high-speed  buffer  amplifi er  made  with 
discrete  components,  which  avoids  interference  between  right 
and left channels and can send the signals to the pre-amplifi er with 
very high fi delity.

Improved momentary current supply ability

It is generally known that the sound quality is not necessarily the 
same even if amplifi ers have the same specifi ations. 
Marantz considers the cause to be the power to drive speakers. 
The  power  amplifi er  of  this  unit  has  the  ability  to  momentarily 
supply current of 25 A or more to drive speakers strongly.

Short-power-line layout

For  strong  momentary  current  supply,  a  short  power-line  layout 
unifi es the power circuit and output stage of the power amplifi er 
section. 
This layout allows connecting the large-current lines via the shortest 
route while to arranging the left and right channels symmetrically.

Main features

All-Discrete current-feedback phono equalizer

As  a  phono  equalizer  amplifi er  for  MM  cartridges,  a  constant 
current-feedback PHONO equalizer of quality equal to that of the 
higher-grade model PM-11S2 is used.

Double-shielded triodal transformer

The unit is equipped with a toroidal power transformer to minimize 
vibration and leakage fl ux specifi c to the transformer. 
Especially to reduce leakage fl ux, which affects sound quality, the 
periphery is double-shielded, using a core ring and a short ring.

Block condenser of large capacity

A large-capacity condenser of 18,000μF is used in the power circuit 
of the power amplifi er. In the preamplifi er, a 4700μF condenser is 
used.

High-performance volume

Capacitor for high quality sound

Double-layered chassis

High-grade speaker terminals

Tri-tone control

This unit has a 3-tone control function for adjusting the midrange 
sound in addition to the bass and treble sounds so that you can 
make a more variable sound adjustment according to source and 
system.
