Commentary
Stereo pre-main amplifier equipped with super stable A circuit.
To achieve high-quality playback, it is equipped with a super-stable A circuit that stabilizes the operation of the power transistor.
The operating point of the power transistor, which fluctuates with temperature changes, is always controlled to the ideal state, and stable playback from minute level to full power is achieved.
The S. L. D. C. (Signal Level Divided Construction) structure that separates the small signal circuit, large signal circuit and microcomputer circuit is used to minimize interference between the circuits.
In addition, the adoption of a double-structured chassis and large transformer base for higher rigidity completely eliminates adverse effects on sound quality from the outside.
Uses a low-impedance volume that greatly improves the SN ratio at the listening level.
It is equipped with a phono equalizer for both MM and MC cartridges.
It comes with a system remote control that supports DENON CD players, cassette decks and tuners.
There was a gold model PMA-715RG with side wood and a black model PMA-715R.
