The Integrated Amplifier which improvement was performed based on PMA-390II and
The thought of an UHC single push pull circuit is inherited, and
HC (High Current) single push pull circuit developed according to the potential
of PMA-390III is carried.
HC-transistor which has current supply capacity
and the capability to be twice many as a transistor usual, in peak current in a
magnification element is adopted, and musical expression ability is raised.
The first recovery diode which working speed is quick in a power-source
part, and has high current supply capability in it is adopted as a rectifier
Moreover, in order to stop the power consumption of the standby at
the time of remote power-off, the power transformer for exclusive use is carried
in each of a microcomputer circuit and an audio circuit. This not only reduces
the power consumption at the time of standby, but the interference to an audio
circuit is eliminated and it is stopping the noise.
such as the time of listening, do not control, the microcomputer stop mode which
stops all the operation of a microcomputer is adopted. The clock oscillation of
the microcomputer stopped at the time of the usual listening, and inflow of the
noise to an audio system is canceled.
An inactive gas enclosure relay is
adopted as the input change of CD and Phono, and generating of the noise which
becomes a cause which soils sound is suppressed. Furthermore, the block
condenser for mass smooth, and the high-quality sound carbon resistance /
capacitor are adopted.
The pre-out terminal is carried.
Operation of the change of main volume and a function, muting, and
remote power on/off (three AC outlet linkage) is possible. Moreover, operation
of CD player and MD recorder of DENON, a tuner, and a cassette deck is also
Operation of dubbing from CD to MD etc. is possible, carrying
the Rec out selector and hearing the monitor of 3 head cassette deck, and a
The sauce direct switch is carried.
