Current feedback type of discrete power amplifier with high sound quality
The MM8003 features in all 8 channels the current feedback type of power amplifi er, which uses the complementary
In the rear section the power amplifier is a current/ voltage conversion amplifier unit that employs a Wilson current mirror circuit for amplifying sound up to the treble range at low distortion levels.
Improved instantaneous current supply capability
In the rear section of the power amplifier is the LAPT
Copper bus bars are featured in the unit that supplies the power to each channel.
The power supply unit has a large toroidal transformer that delivers low levels of noise and leakage fl ux thanks to its internal structural features such as its laminated core, silicon
Original Marantz parts with a combined capacitance of 100,000 µF (50,000µF/71V × 2), which have been specially crafted to achieve the maximum in terms of sound quality, are employed in the block capacitor, a key component of the power supply unit.
Thanks to the improvements in the current supply capability of these parts, you can enjoy
A
These features together make for lavish specifications well suited to the amplifier's use in
The amplifi er's chassis is
In addition,
BALANCED/UNBALANCED switching function This function makes it possible to select BALANCED or UNBALANCED input each channel depending on the application.
Remote power control
By connecting the amplifier to Marantz's model AV8003 AV
A fl oating ground connection that doesn’t form a ground loop is used for the connection with the AV8003 so the sound quality is not adversely affected.
Other functions
Also provided are an IR flasher input connector to support customized installation, and DC trigger input connector and output connectors.
