The Integrated Amplifier which carries a digital
A version LSI (TDA1541A) which Philips is proud of is
adopted as a digital analog converter, and the digital signal is made to link to
a highly precise analog circuit.
Thorough serious consideration of the
S/N was carried out at the volume part, and the 4-unit master volume is adopted.
Moreover, the final stage of an amplifier part has adopted the three-step
Darlington parallel push pull.
A large-sized transformer and capacitor
are carried in the power-source part.
In order to prevent the wraparound of
a digital noise, the D/A independent-source circuitry is adopted, and the analog
system serves as a high stable high speed power source which made full use of
high-integrated IC of a low-noise wide band.
The side panel of
die-casting is adopted as a sub-.
Furthermore, die-casting framing which
eliminated the ill effect of the oscillation is adopted, and the fine
oscillation of the circuit board is also effectively controlled by the newly
developed vibration suppression substrate material.
corresponds to three optical 1 coaxials, and the input unit supports all
sampling-frequency 32/44.1/48kHz signals.
Moreover, the analog input serves
as a design corresponding to the multi-source having those with seven line, and
a Phono equalizer (MC, man month). The tapes circuitries are two analogs which
can do mutual dubbing freely.
A tone control circuit is the shelving
type which set center frequency as 60Hz and 15kHz, is suppressing an elevation
of an unnecessary band, and it is considered so that a distorted incrementation
and inflow of a noise may be prevented.
The Source-Direct functionality
is carried, each stage to flat amplifier is jumped, and not only the output of a
digital analog converter but analog output can be directly linked with a master
The Jitter absorbing circuit is carried so that the fluctuation
of the optical digital signal by oscillation of an optical cable etc. (Jitter)
may be rectified.
The remote control which summarized the functionality
compactly is equipped standardly.
