Features
Current feedback discrete power amp This unit 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 x 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.

XLR connector PIN arrangement
This device uses the European method for XLR pin arrangement. For devices using the USA method (where pin 2 is COLD and pin 3 is HOT), you may need to swap the plugs on one side of the balanced cable. Do not short HOT/GND or COLD/GND.
Speaker connections
Carefully check the channels of the speakers (L/R/SL/SR/C) and connect the positive (+) terminals (red) to positive and negative (-) terminals (black) to negative.
Connecting the speaker cables
Peel off approximately 0.03 ft (10 mm) of sheathing from the tip of the speaker cable. Twist the core wire tightly or use a terminal for connection. Ensure speaker cable core wires do not protrude from the terminal, as this could activate the protection circuit. Never touch speaker terminals while the power supply is connected to prevent electric shock. Use speakers with an impedance of 6 to 8 Ω.
Sets the connected input connectors
Use the input selector switch to choose between BALANCED (for XLR connectors) and UNBALANCED (for RCA connectors). If audio is input into connectors not set via the input switching switch, no audio will be output from the speakers.
