3. Main features of this product

The concept: channel separation for super wide range & dynamic audio

We think it’s of the utmost importance to extend high frequency response as well as channel separation so you can hear the true meaning 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.

Fully balanced control amp with an linear volume control

The SC-7S1 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 (High Definition 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.

HDAM SA

The feedback impedance of the Current Feedback circuit was reduced to its minimum to make it faster. We developed a new High Definition Amplifier Modules (HDAM), a separeted module operating as a buffer for the amplifier. The SC-7S1 has four HDAM SAs on each inputoutput buffer and another four units on the V/I converter.

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.

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-7S1 and four sets of MA9S1 are connected in a bi-amped mode.

You will experience superb sound with unbelievable channel separation.

4. Connections

Connection 1–4 are recommended by Marantz for SC-7S1 with Marantz MA-9S1.

If using the MA-9S1s, Please read the instruction manual for the MA-9S1.

Name and Function P13

Standard set-up in using Marantz Monaural Power Amp

MA-9S1.

Please refer to this connection in the event of using other Power

Amps also.

SC-7S1 doesn't have a Phono equalizer. So in the event of using a turn table, please use a Phono equalizer to connect with the SC-7S1.

In the event that stereo L ch signal has been wired with A ch input, the signal will come out of the pre-out of the A ch. Please pay attention to L ch, R ch if SC-7S1 is connected with other equipment.

Balanced terminal

The balanced output connector uses a XLR connector.

The XLR connector is internally wired in either of the following two systems.

1. USA system (Pin 2 = COLD, Pin 3 = HOT)

2 . European system (Pin 2 = HOT, Pin 3 = COLD)

The SC-7S1 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 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.

This connection can have options i.e. You may connect the units using either balanced or unbalanced cables to connect your SACD/CD and control Amp. But you can not inter match.

Please select either way of connection.

Enhance the connection 1 to Bi-Amp connection, and drive the Bass speaker and Mid/High speakers with separate power Amplifiers.

Bi-Amp (connection)

The benefits of Bi-Wiring; drive the Bass speaker and Mid/High speakers with separate power Amplifiers. Bi-Amping will lessen the burden of Power Amp impedance, so that back electromotive force between the Low and Mid/High signal can be lessened. We can expect drastic improvement of sound quality.

4. Connections

This connection can have options i.e. You may connect the units using either balanced or unbalanced cables to connect your SACD/CD and control Amp. But you can not inter match. Your Control Amp & Power Amp can also be wired the same way. Please select either way of connection.

Complete Bi-Amp connection

Enhance connection 2, by having one more control Amp. SC7S1, this is a wiring which separates Mid/High signal and Low signal from the Pre-Amp section. In this event, the SC-7S1 is used as Monaural Pre-Amps. And separate Left/Right channels from the output terminal of CD player. As a result, influences between L channel and R channel Mid/High signal and Low signal will be eliminated.

By connection with the remote cable, a maximum of 6 SC-71s can be operated together.

Caution

In the event of setting the mode switch as <Bi-Amp>, B channel input can't be used.

Installing the SACD multi-channel audio speakers

In order to enjoy SACD 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).

SACD 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-

1recommendation.

On SACD 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.

The location of the sub-woofer in the picture is just an example. The Sub-woofer can be located any place in your room. (See the users manual of your sub-woofer.)
