MAIN FEATURE OF PRODUCT  
7 The concept: channel separation  
for super wide range & dynamic  
audio  
7 Fully balanced control amp with  
an linear volume control  
The SC-7S2 is a full balanced, two-channel control amp  
providing the channel separation you need for Super Audio.  
Based on our own high quality four-gang active volume control  
we have developed an even better linear control volume that  
reduces gang errors from 0 to 100dB, 0.5dB. By adding an  
additional HDAM SA (Hyper Dynamic Amplifier Module), we  
improved the Common Mode Reject Ratio (CMRR)  
dramatically, attaining an incredible ultra-wide frequency band  
of 150kHz and succeeded in producing the perfect control  
amplifier for Super Audio CD.  
We think its of the utmost importance to extend high frequency  
response as well as channel separation so you can hear the  
true meating of Super Audio.”  
This is why we have designed the input and output circuitry,  
volume control section, and power supply circuits according  
to this philosophy.  
The result: an astonishing channel separation of over 100dB  
at 20kHz.  
7 HDAM SA  
The feedback impedance of the Current Feedback circuit was  
reduced to its minimum to make it faster. We developed a new  
Hyper Dynamic Amplifier Modules (HDAM), a separeted  
module operating as a buffer for the amplifier. The SC-7S2  
has four HDAM SA on each input-output buffer and another  
four units on the V/I converter.  
7 Choke input system  
In the power supply section, the choke input topology was  
adopted to drastically reduce rectifier harmonic noise. This  
system is especially suitable for a control amplifier in which  
very small signal amplification occurs.  
7 Floating control bus system  
We make it possible to synchronously drive two or more control  
amps by using a floating control bus system connected to as  
many as 6 sets of control amplifiers. We also enable you to  
trim levels using the remote control, making it easy to set up  
the optimal sound field on a multi-channel configuration. The  
highest achievable stereo performance can be accomplished  
when a system configured with two sets of SC-7S2 and four  
sets of MA-9S2 are connected in a bi-amped mode.  
You will experience superb sound with unbelievable channel  
separation.

If using the MA-9S2s, Please read the instruction manual for the MA-9S2.  
Name and Function P13  
Standard set-up in using Marantz Monaural Power Amp MA-  
9S2.  
Please refer to this connection in event of using other Power  
Amps also.  
SC-7S2 doesn't have Phono equalizer. So in the event of  
using a turn table, please use a Phono equalizer to connect  
with the SC-7S2.  
In event that stereo L ch signal has been wired with A ch  
input, the signal will come out of the pre-out of A ch. Please  
pay attention to L ch, R ch if SC-7S2 is connected with the  
other equipment.  
BALANCED TERMINAL

following two systems.

e The SC-7S2 uses the USA system of 1.  
When a preamp or main amplifier adopting the European  
system is connected using a cable with XLR balanced  
connectors, the reproduced signal may be inverted of  
phase.  
In this case, correct the wiring of the one of the XLR  
connectors on the extremities of the cable to the USA  
system by exchanging the connections of pins 2 and 3.  
This will make it possible to play the signal with the correct  
phase.

Broadcasting Section.  
ITU-R BS in the recommendation which consists of standards  
relating to broadcasting (audio) operations, one of which is  
the ITU-R BS.775-1 which governs multi-channel stereo sound  
systems.”  
In order to enjoy Super Audio CD multi-channel sound with  
the best possible acoustics, it is recommended that the speaker  
systems be laid out in compliance with the ITU-R BS.775-1  
recommendation which is a standard formulated by the  
International Telecommunication Union (ITU).  
Super Audio CD multi-channel discs are recorded and mixed  
in such a way that they will achieve the optimum effects when  
the speaker systems are laid out as per the ITU-R BS.775-1  
recommendation.  
On Super Audio CD multi-channel discs, the music signals  
are basically recorded using 5 channels (or 3, 4 or 6  
channels in some cases). In some instances, however,  
LFE (for the sub woofer) is recorded as a sixth channel.  
Each disc indicates how many channels have been  
recorded on it.  
The basic settings are 3 speakers for front and 2 for back  
since multi-channel discs have basically 5 channels  
The 2-front, 1-center, and 2-surround speakers should be  
set on the circle from the listening point as shown below.  
When you use different sizes of speakers, please adjust  
the volume balances.
