DENON PMA-7.5
¥ 49,800 (around 1993)
Commentary
A full-scale pre-main amplifier that uses a large toroidal transformer in a compact size.
The power supply section uses a toroidal transformer to provide a stable supply of current, reduce leakage flux, and prevent vibration.
With a source direct switch, it is possible to bypass the tone control circuit.
It uses low-impedance volume control that greatly improves the SN ratio at general listening levels.
It is possible to develop the system by connecting an AV preamplifier, graphic equalizer and processor.
With the included remote control, you can control DENON CD player, cassette deck and tuner in addition to the control of the main unit.
