General Precautions

When siting the equipment ensure that:

— the ventilation holes are not covered; — air is allowed to circulate freely around the equipment — it is on a vibration free-surface; — it will not be exposed to interference from an external

source;

— it will not be exposed to excessive heat, cold, mois

ture or dust; — it will not be exposed to direct sunlight; — it will not be exposed to electrostatic discharges

Never place heavy objects on the equipment. If a foreign body or water does enter the equipment, contact your nearest dealer or service centre. Do not pull out the plug by pulling on the mains lead, hold the plug. It is advisable when leaving the house, or during a thunderstorm, to disconnect the equipment from the mains supply.

3. Main feature of product

●

The concept : Instantaneous current

delivery capability

Even if amplifier have the same power specifications, their performance may not be the same due to a difference in current delivery capability. The delivery capability of 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 push-pull balanced construction, for the final buffer amp of 6dB.

●

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 separated module operating as a buffer for the amplifier.

●

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.

ENGLISH

●

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.

■ Installing the SACD multi-channel

ENGLISH

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.775-1 recommendation.

●

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.
