The Integrated Amplifier which hits the succeeding
machine of model PM-80 which continued long-term seller.
The technology
adopted from high order models, such as a full-scale 3 amplifier stream
composition, the new model MOS FET, 4-unit active volume, is introduced.
In order to press down distortion also to the input of the high-level
sources, such as compact disk, and to maintain stability, 3 amplifier stream
compositions which became independent about each amplifier block of a pre, a
tone, and power are adopted.
Moreover, the first rank of each amplifier of
an equalizer, a pre, and power serves as the same circuitry as HDAM.
Large-sized MOS FET is used for the ensemble of a power block by the
parallel push pull, and high electric-current drive capacity is secured.
Moreover, the same circuitry as HDAM is constituted in the phone equalizer
treating minute level.
The 4-unit active volume which has improved S/N
of a real busy condition sharply is carried in the volume.
The same pre part
of circuitry as HDAM a volume unit and really has composition, performed the
copper shielding treatment and has gained high S/N.
The large-sized
power transformer, and the special edition and the low double foil electrolytic
capacitor of 15,000 micro Fx2 are adopted as a power-source part.
Moreover,
the noise-killer element which absorbs a RF noise is adopted as an output power
source and a voltage amplification part power source.
In order to
improve rigidity, the chassis is pinched from both sub-s by the die-casting side
panel.
There was also a black model besides a gold model.
