The

DENON PMA-7.5
49,800yen(around the 1993 time)

Description
 
The formal Integrated Amplifier which adopted the large-sized toroidal transformer as compact size.

The toroidal transformer is adopted as a power-source part in order to aim at prevention of the stable supply of current, leakage flux reduction, and vibration etc.

It is possible to carry the sauce direct switch and to bypass a tone control circuit.

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

It is possible by connecting AV preamplifier, a graphic equalizer, a processor, etc. to develop a system.

It is possible to control CD player of DENON, a cassette deck, and a tuner with attached remote control besides control of a main part.
