ENGLISH
The PM7001 is an integrated amplifier developed on the design
concepts of Marantz’s PM-11S1 high-end model amplifier.
• CD Direct Buffer Amplifier
The PM7001 incorporates a specialized input buffer amplifier
nearby the CD input jack. This buffer amplifier faithfully transmits
the CD input jack signal by preventing interference from
between the left and right channels, and from the effects of
other circuits. A discrete configuration high-speed buffer
amplifier which is built on the HDAM
®
SA technology is
incorporated into the buffer amplifier circuit.
• CD Direct Selector
The output of CD direct buffer amplifier has a specialized relay
switch, which directly transmits the input signal by the shortest
path to the pre-amplifier.
• Improved Momentary-Current Supply
Capability
It is known that sound quality differs between amplifiers that
use the same spec, and Marantz believes that this is caused
by differences in speaker drive capability. The PM7001 main-
amplifier has the capability to momentarily pass 25 amperes
or more of current, providing high-powered drive to the
speakers.

• Short Power Line Layout
In order to improve the momentary-current supply capability,
a new layout which places priority on making the large current
line connections as short as possible was adopted.
In this layout the power supply circuit, main-amplifier output
stage, and heatsink are unified, and the large current line is
arranged to be as short as possible while still achieving
symmetry on the left and right sides.
• Current Feedback Amplifier
Both pre-amplifier and main-amplifier incorporate a high-speed
current feedback amplifier circuit, which faithfully amplify
signals from the CD player. Moreover, the high-speed current
feedback amplifier reproduces a natural sound field space.
