The Integrated Amplifier of the limited model announced in October, 2001 in
commemoration of having changed the name into DENON (Denon) from DENON (Denon).
Large current type magnification element UHC-MOS used for highest-class
monophonic amplifier POA-S1 of DENON was adopted, the UHC single push pull
circuit was strengthened further, and high power has been obtained, giving power
The toroidal transformer which has a large-sized
magnetism circuit in the power transformer of a power supply circuit is adopted, and the flattery nature to a music signal is improved by performing the design
which has a large dynamic range to a magnetic saturation domain. Moreover, in
order to suppress the influence of vibration of a toroidal transformer, the
method of fixing an S.B. (Stable Based) system using an aluminum sand casting
case is adopted. Furthermore, it becomes independent about the winding wire of
the power source of a power-source magnification stage or a phone equalizer, and
the mutual intervention between each circuit is suppressed.
In order to
have adopted the newly developed thing as a block condenser and to suppress the
influence by vibration, it is fixing with the stabilizer made from an aluminum
In moreover, the rectifier circuit which changes into a
direct-current power source the AC power outputted from the power transformer, and is supplied to an amplifier partThe Schottky barrier diode developed for
high frequency rectification is carried by parallel connection, and the
low-noise, low loss, and improvement in the speed of the power supply circuit
are attained by the low-noise characteristic and the large current
characteristic by high-speed operation.
Furthermore, improvement of the
characteristic and stable current supply in a play frequency all zone are
planned with the combination of the capacitor by which the mass electrolytic
condenser which uses low impedance electrode foil differs from a frequency
OFC wiring material is used for wiring from a power transformer
output to a power amplifier output stage, and the energy loss is suppressed to
it to the minimum.
Sound quality degradation by the mutual intervention
between circuits or inflow of a noise is suppressed by adopting the twin
monophonic composition which became independent by right and left about the
power amplifier block, and also adopting 6 block structures which put into
practice separation and cover of the circuit where signal levels differ.
Furthermore, a power amplifier circuit / power radiator is separated with a
power transformer, and, also mechanically, it is covering.
order to suppress generating of the noise by vibration, while adopting as a
chassis the sheet steel with a thickness of 1.6mm which performed black paint
and securing rigidity, equalization of the temperature in a chassis is attained.
While adopting the newly developed product made of cast iron as an
insulator, the vibrational absorption effect is heightened by adopting hybrid
construction with the high new materials of vibrational absorption nature.
Each of the volume circuit, the tone circuit, and the power amplifier
circuit was improved, and the maximum of the frequency response at the time of
real use is improved to 100kHz. Furthermore, the noise generated within
amplifier by improving a volume circuit at the time of real use is stopped, and
correspondence to the large frequency response and dynamic range which
next-generation media have is aimed at by improving resolving power.
Precision Signal Ground circuit is carried and inflow of noise current, such as
a constant current circuit, is reduced to the grand circuit used as the
origin/datum of signal magnification.
what carried out brass shaving
appearance, plated with gold at the part, and reduced the transmission loss is
adopted as a speaker terminal.
Moreover, the bore diameter of a clamp part
is made large-sized with phi6mm, and correspondence to a very-thick speaker
cable is aimed at.
The phone equalizer which adopted the first rank
circuit of discrete composition of having used low-noise FET is carried in the
phone equalizer part. High-quality sound-ization is attained by the regulated
power supply only for a phone equalizer.
Moreover, the changeover switch is
prepared in order to correspond to each cartridge of MM/MC.
and carrying out large-sized shaving appearance of the 40 type 4-unit volume --
a gilding pin jack,Complete reexamination of parts adopted by PMA-S10III, such
as OFC internal wiring material, an inactive gas enclosure type relay, a
high-quality sound film capacitor, a high-quality sound electrolytic condenser, and an attachment-and-detachment type OFC power cable, was performed, and the
newly developed part is adopted.
