Description
 
The stereo Integrated Amplifier which carries a Si Perth table A circuit.

In order to realize a high-definition play, the Xu Perth table A circuit which stabilizes operation of a power transistor is carried.
The operating point of the power transistor changed to a temperature change is always controlled in the ideal state, and the play stabilized from a minute level to full power is realized.

The S.L.D.C. (Signal Level Divided Construction) structure of separating a small signal circuit, the Taishin number circuit, and a microcomputer circuit is adopted, and an interference mutual [ between circuits ] is suppressed to the minimum.
Furthermore, the bad influence which it has on sound quality from the exterior is also thoroughly eliminated by high rigidity-ization by the chassis of double structure, and adoption of a large-sized transformer base.

The low impedance volume which raises sharply the signal to noise ratio in a listening level is adopted.

The phone equalizer corresponding to a MM/MC car cartridge is carried.

The system remote control corresponding to CD player made from DENON, a cassette deck, and a tuner is attached.

There were PMA-715RG of the gold model to which side wood was attached, and PMA-715R of a black model.
