The Integrated Amplifier which supplied the separate amplifier technology of the Marantz.
The output stage has triple push
pull composition which adopted MOS FET.
MOS FET "can respond also to high
resisting pressure and large electrification, while it has a good RF property".
"in order to operate only by a majority carrier theoretically,It has the
distinctive characteristicses, such as implementation being" and "the turn-off
time being shortened extremely and a fast switching being possible, since there are few store-recording effects at the time of switching", for the high input
impedance more than J-FET, and the ideal operation is conjointly realized with
the quarter A original with a Marantz.
The original quarter A circuit is
adopted, one fourth of the maximum output performs a perfect pure Class-A
operation, and the maximum output beyond it shifts it to AB class operation
automatically. This auto shift is controlled by the electronic control, detects
the Output voltage of a main amplifier and is controlling the bias current by
the fast-switching circuitry.
In PM-94, rather than the conventional quarter
A circuit, the detection velocity is improved and the more smooth control is
In order to fully demonstrate the performance of MC cartridge, a two-piece right-and-left independency is achieved, and the highly efficient MC
transformer is carried in MC input.
With 2 coil stream compositions, the
double shielding of the orientation of a core and the orientation of a coil is
used for this transformer, and it has obtained the quality for which the
high-quality sound MC transformer "MC1000" is pressed.
Moreover, the boost
ratio serves as a High-Low change type.
The large-sized transformer and
the 90,000-micro F large-sized electrolytic capacitor are carried in the
The three-fold silicon-steel-plate shielding was
performed, and the measures against flux are thoroughly taken especially against
the toroidal transformer.
The material "raincoat tightness" of the
copper plating steel plate was extensively adopted as the chassis, and the
effect more than the conventional copper plating has been acquired by the
raincoat tightness of uniform copper plating finish on it.
tuning, such as adopting the parts examined in the hearing, is performed.
pair electrolytic capacitor equivalent also to a property and a tone quality and
each switchpoints which carried out the tone-quality modification by copper
plating were adopted, and also the 70-micron-thick circuit board and an
oxygen-free-high-conductivity-copper product-line code are supplied.
Moreover, in order to eliminate the tone-quality transition by a pewter, the
capacitor was used as the screw stop and all screws have adopted the copper
compact-disk direct position is carried. By this position, stages, such
as an input selector tapes monitor, are jumped and it is directly linked
with flat amplifier from a direct master volume. And most transitions of
an input impedance can disregard flat amplifier also to a resistor transition
of the master volume itself for an FET input.
HiFiVCR monitor position is carried and the music play by HiFiVCR can be enjoyed
with the same sensation as a tapes monitor.
