High quality sound
•All-discrete current-feedback amplifier
Marantz proprietary current-feedback circuit, using discrete components,
is adopted in the pre-amplifier and power amplifier. It is a high-speed
amplifier using the latest technology developed for the higher-grade
amplifiers.
•HDAM
®
SA3 Module
This unit includes the HDAM®SA3 which had been developed for high-
end models. The HDAM®SA3 is incorporated into many components,
such as the current feedback phono equalizer.
•Improved momentary current supply ability
It is generally known that the sound quality is not necessarily the same
even if amplifiers have the same specifiations. Marantz considers the
cause to be the power to drive speakers. The power amplifier of this unit
has the ability to momentarily supply current of 45 A or more to drive
speakers strongly.
•Short-power-line layout
For strong momentary current supply, a short power-line layout unifies
the power circuit and output stage of the power amplifier section.
This layout allows connecting the large-current lines via the shortest
route while to arranging the left and right channels symmetrically.
•CD direct buer amplifier
An input buer amplifier exclusive for CD is mounted near the CD
input jacks. This is a high-speed buer amplifier made with discrete
components, which avoids interference between right and left channels
and can send the signals to the pre-amplifier with very high fidelity.
•All-Discrete current-feedback phono equalizer
As a phono equalizer amplifier for MM cartridges, a constant current-
feedback PHONO equalizer of quality equal to that of the higher-grade
model is used.
