Features

Current feedback discrete power amp

This is equipped with a current feedback power amp that uses the complimentary push-pull circuit used in the marantz Hi-Fi power amp. This amp provides increased operating stability, and high- speed, wide ranging high-density playback.

The current/voltage conversion amplification section in the latter part of the power amp is equipped with a Wilson current mirror circuit that amplifies to the high sound range with low distortion.

Improved instant power supply capability

The final stage of the power amp is equipped with the same LAPT (high efficiency power transistor) that is installed in the marantz Hi-Fi power amp, providing improved instant power supply capability.

The power section is equipped with a large-sized transformer.

As one of the essential parts of the power section, this unit is equipped with marantz original 50,000 μF / 71 V × 2 block condensers, which have been repeatedly tested for sound quality. These improvements to the power supply capability provide a powerful, presence-filled sound.

High sound quality design based on pure surround philosophy

Equipped with a chimney-shaped heat sink to efficiently process the heat emitted from each channel amp , and exceptionally quiet cooling fans. A high-sensitivity temperature sensor IC is used to control the cooling fans, adjusting the rotation speed to match the amount of heat generated by the amp.

These components provide the sound quality and low-noise you would expect at a high-end theater.

In addition, this unit is designed for superb quality sound, and is equipped with high quality components such as a high-end audio condenser and film condenser throughout.

BALANCED/UNBALANCED selecting function

Depending on the desired use, input for each channel can be selected between BALANCED input and UNBALANCED input.

Remote Power Control

This unit is equipped with a remote power control function. When a marantz AV Pre Tuner AV8801 or AV7701 is connected to this unit, this unit’s power can be switched ON/OFF together with the AV8801 or AV7701 power supply.

Connection to the AV8801 or AV7701 is a ground floating connection that prevents negative influences on sound quality as far as possible.

Other Functions

Equipped with IR flash input that supports custom installations, and DC trigger input and output terminals.

Cautions on handling

•Before turning the power switch on

Check once again that all connections are correct and that there are no problems with the connection cables.

•Power is supplied to some of the circuitry even when the unit is set to the standby mode. When going on vacation or leaving home for long periods of time, be sure to unplug the power cord from the power outlet.

•About condensation

If there is a major difference in temperature between the inside of the unit and the surroundings, condensation (dew) may form on the operating parts inside the unit, causing the unit not to operate properly.

If this happens, let the unit sit for an hour or two with the power turned off and wait until there is little difference in temperature before using the unit.

•Cautions on using mobile phones

Using a mobile phone near this unit may result in noise. If that occurs, move the mobile phone away from this unit when it is in use.

•Moving the unit

Turn off the power and unplug the power cord from the power outlet. Next, disconnect the connection cables to other system units before moving the unit.

•About Care

•Wipe the cabinet and control panel clean with a soft cloth.

•Follow the instructions when using a chemical cleaner.

•Benzene, paint thinner or other organic solvents as well as insecticide may cause material changes and discoloration if brought into contact with the unit, and should therefore not be used.
