The Integrated Amplifier which gave tune amplifier
based on the chassis construction of PM-90.
The unification part of SE
series and newly developed technologies including a high-speed module are
supplied, and S/N on Hearing impression and the further improvement in speaker
drive capacity are aimed at.
A total of ten HDAM which is the high-speed
voltage amplification modules which realize an exact signal amplification in
several seconds is adopted.
Thereby, a feeling of density and speediness of
play sound are improved.
The new model MOS FET was selected carefully to
the power block, and it has adopted by the parallel push pull.
electric-current drive capacity to exceed the time of a triple push pull using
of conventional MOS FET by this is acquired.
By combining HDAM with
4-unit active volume, the volume part has expanded the gain variable span
sharply. Moreover, by adopting a resistor rotation type as volume component
partses, and considering it as a low-impedance specification, S/N at the time of
a real using is raised.
The low double foil chemicon with a copper shielding, the top cover of the 70micro foil printed circuit board, a silicon steel board shielding board, a sub- die-casting panel, a copper plating die-casting chassis, and 3mm thickness, etc. are adopted, and shielding capacity and vibration suppression nature are raised.
The large-sized toroidal power
transformer is adopted as a power-source part.
