Marantz Reference Series SC-7S1 - Manual (Page 7)

What Legends are made of.....
We’ll never forget the impact the introduction of the
Marantz Model 7 and Model 9 had on the industry more
than 40 years ago. These models fused original circuit design with
rational thinking and aesthetic appeal. Not only did these models help
establish the Marantz name and brand in the audio world, but also
influenced the direction that audio evolution has taken ever since.
Today, the Model 7 and Model 9 remain an industry standard
and have secured a place in the analog era. They continue to be the
audio components of choice by many people. Their rebirth is not for
nostalgia’s sake, but pride and pleasure. The Model 7 and Model 9
live again, a celebration to their essence.
That the Model 7 and Model 9 are still sought-after-components
is a testament to the fact that even though musical sources may have
changed, thoughtful design and engineering continue to endure,
defying the laws of music and audio history. Reviving these two
numbers will once again enrich audio history.
The distinctive voices of the Model 7 and the Model 9 have been
reborn in the SC-7S1 and MA-9S1. Each draws out the musical
potential of, for example, Super Audio CD and has therefore the
capability to superbly reproduce musical formats of the future.
Improvements while maintaining original integrity include:
• Enhancement of channel separation in the high frequency range
• Significant reduction of cross talk
• Low impedance drive capability
• High-speed signal handling capability
• High instantaneous current delivery capability
• Highest reproduction capability for super wide range & dynamic
range audio.
Even in this technological era you will understand why we’ve
assigned the numbers 7 and 9 to the nameplate of these products.
You will recognize their distinct voice when you listen to them.

MA-9S1
Instantaneous current
delivery capability
Even if amplifiers have the same
power specifications, their performance
may not be the same due to a
difference in current delivery capability.
The delivery capability of a power
amplifier depends on how instantaneous
the current supply is. That’s why
the power supply for the MA-9S1 was
completely revamped to give it a truly
instantaneous current supply capability
that has been increased three times as
much compared to any Marantz
product designed before. Fully balanced monaural power amp
To minimize the influence of strong
“return current” occurring from the
loudspeaker system, the circuit for the
power amp consists of two amplifiers
giving a voltage gain amp of 23dB,
in a 3 paralleled push-pull balanced
construction, for the final buffer amp
of 6dB.
Choke input system
The power supply of the voltage gain
amplifier’s adopted choke input system
has few ripples and is durable with load
changes. This can prevent noise from
the amplifier as well as reduce noise
from the primary winding, resulting in
a clean power supply.
Ultra low impedance amplifier
The buffer amplifier’s power supply
block, which supports the high current
delivery capability, uses a capacitance
input system to realize very low
impedance. The Super Ring power
transformer, the low impedance
electrolytic capacitors, the very large
gauge internal wiring, and the thick
pattern PCB all contribute in supplying
the required power.
