The Integrated Amplifier which improvement was performed based on PMA-390II and born.

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 circuit.
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.

When microcomputers, 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 possible.

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 record.

The sauce direct switch is carried.

Phono equalizer amplifier is carried.

Two kinds of color variations, gold and black, occurred.
