Custom Audio Components
Many Marantz custom audio components that have
been carefully selected for their exquisite sound quality
are used on the PM7004. Two 15,000 µF high-capacity
capacitors are used in the power amp power supply
circuit that is vital for supplying the current, and two
capacitors for the 3,300 µF high-grade audio diode
are used in the preamp power circuit. In addition, as
in the high-end model, the PM7004 contains many
high-grade components, such as a Schottky barrier
diode with high response speed and low noise and a
Marantz original noise-killer element.
Short Power Line Layout
A short power line layout that integrates the power
circuit and power amp output stage is used to improve
the instantaneous current supply performance. This
layout connects the large current line by the shortest
distance in a left/right symmetrical layout.
Tri-Tone Control Function
This is a 3 band (Bass, Mid, Treble) tone control function
that in addition to controlling the low frequency and
high frequency bands, also controls the mid frequency
band, which is the band of vocals and fundamental
instrument pitches to which the human ear is most
sensitive. Use this function to adjust the sound quality
to that preferred for the conditions of various sound
sources. The tone control circuit employs an active fi lter
that gives priority to sound quality. All of the frequency
characteristics in the center position are fl at.
Fully discrete current feedback amplifi er
Improved instantaneous current
supply capability
Even if the amps have the same power specifi cations,
the actual speaker drive capability differs among
products. Marantz reasons this is due to the difference
in instantaneous current supply capability from the amp
to the speakers. This power amp was given the ability
to instantaneously pass a current of 25 ampere or more
by optimizing the overall circuit by improving the
components, such as by using a powerful power supply,
short power line layout, and low impedance circuit.
This accurately drives the speakers at high speed.
