The Integrated Amplifier which carried out the
digestive development of the know-how for the super-low-pass representation
obtained by M-07, the disposal method of the very small signal acquired by C-06
or E-06, etc.
The power amplifier part has adopted the pure Class-A
Since the bias current which was fixed to the maximum output is
supplied, there is no variation of the point of operation by a signal, and the
high-definition power quality of a Class-A operation no one but has been
Compared with the amplifier of this usual class, the mass
large power transformer is adopted as a power-source part no less than 30%.
The constant-voltage regulated power supply of each stage independent coil
is adopted, thorough low-impedance-ization is attained, and instant response
capacity is improved.
Especially the current capacity to the power stage
gives 1.5 times [ usual ] as many margins, and is carrying out
The signal path in which it results to a speaker termination has a structure which carried out thorough exclusion of complicated leading about or the excessive part from the input terminal.
the selection termination was made the change of the input with the remote
switching in the minimum location near an input terminal also including the
grounding side, and the nitrogen gas enclosure money contact relay is adopted as
The speaker termination is directly linked with the power stage,
without special-purpose-izing without an A/B switching, and also losing even a
headphone jack, and passing an excessive circuitry.
Product-line material is
using PC-OCC of the measure against a tone quality for the key point.
absent-resonance bottom chassis is adopted as a bottom chassis, and
absent-resonance-ization is conjointly attained with the construction with a
symmetric weight balance.
The amplifier for MC cartridges and the amplifier for man-month cartridges are special-purpose-ized, respectively, and
are carried independently.
With MC amplifier, the power-source part has
realized the very low-noise power source by a low-impedance output by adopting
the low-noise reference-voltage power source which combined constant current and
a constant voltage by carrying out the parallel using of the super low-noise
high gain FET.
Moreover, an equalizer amplifier is also considered as a
Class-A operation, and enables the high-definition analog-disk play.
ultimate Attenuator is adopted as a volume control functionality.
Since the conventional general succession good transformation volume was
the way a metals carries out the contact slide of the carbon skin film
top, there was a threshold on a tone quality according to the stray current,
the contact quality of the material, etc. of a slide part. With however,
an ultimate AttenuatorBased on the newly developed slide rotary switch,
every piece is mounted on a glass epoxy gilding substrate, respectively,
and the non-magnetic-material resistor is used as 32 contact rotary switch
type Attenuator constituted from a shielding case by die-casting extrusion
This is suppressing
the tone-quality failure in a volume.
In order to guarantee the stable
operation, the Hy Effie Shen See radiator which adopted the fin of the high pure
copper of the heat-dissipation effect is newly developed and adopted.
using everywhere the same material as a resistor and the power amplifier M-07 of
a gilding cap, the improvement in a tone quality is aimed at further.
Furthermore, tone-quality measure parts, such as a highly efficient styrene
capacitor and a pure Focus type electrolytic capacitor, are adopted.
tone Compensation is adopted as a tone-quality correction controller.
sound-recording output is separated from a signal system, and the recording
selector for a sound-recording output switching prevents a tone-quality failure
in an OFF location.
It is possible to have adopted the line phase sensor
and to unite correctly a power-source polarity (orientation which
