Marantz PM8100SA ver.2 75,000yen(July, 2003 release)

Description
 
The Integrated Amplifier which supplied the circuitry high speed technology according PM8100SA to Absolute SA Technology original with a Marantz to the base, and raised completeness to it.

The multichannel input/output terminal is carried and it can develop into a multichannel play by adding power amplifier, such as SM6100SA ver.2.

The capacitor only for an audio is adopted as 17 decoupling capacitors of a pre part and the Power part. Moreover, the newly developed high-quality sound film capacitor is adopted everywhere. Furthermore, the schottky-barrier diode of the low-noise adopted with separate amplifier is used for a power-source block, and low-noise-ization is attained as it is efficient.

Grand potential is improved completely, repeating a tone-quality study, and the shake of potential is suppressed.

A six-channel preamplifier is carried.
Low-noise-izing and a high slew rate are realized by adopting a current feedback type as all the circuitry of six channels, and using a high precision low-noise metal film resistor and a film capacitor.

The motor-drive 6-unit volume of a die-casting frame is adopted as a volume.
From the conventional thing, this volume has little deflection between channels, and has obtained tone-quality performance higher than an electronic volume.

The current feedback type circuitry is adopted as a stereo power amplifier block. The phase compensation was made light by lowering a feedback impedance, and high speed amplifier is realized.
Moreover, in PM8100SA ver.2, parts which carried out with separate amplifier and it had, such as a film capacitor and a resistor, are adopted. Furthermore, the power device has adopted the transistor LAPT for audios excellent in the high region property.

The oscillation and the thermal crosstalk are reduced by making a heat sink on either side become independent.

The super ring-core toroidal transformer with little leakage magnetic flux is adopted as a power-source part. Moreover, the schottky-barrier diode is adopted as a rectifier circuit.

compact disk and the DVD input serve as a direct input design linking directly to a preamplifier part from the input terminal by the exclusive relay.

The speaker terminal made from German WBT is adopted as a speaker termination.

The full REC serector with the Lec buffer is carried.

The double layered chassis is adopted.

The phone equalizer amplifier corresponding to man-month cartridge is carried.

The inlet type AC cable is adopted.

Wireless remote control is attached.
