DENON PMA-390II

Commentary

A pre-main amplifier developed as a successor model of PMA 390.

The signal line leading to the input terminal and speaker terminal has been simplified by ensuring the proper placement of switches and volumes and by the proper placement of parts using DENON's unique short signal technology.

Equipped with three tone controls for bass, treble and variable loudness, you can adjust the bass and treble ranges.
In addition, there is a source direct switch. When this switch is turned ON, it bypasses the tone control circuit and balance circuit and is directly input to the power amplifier circuit via the main volume.

It is equipped with an equalizer amplifier compatible with MM cartridge.

It comes with a system remote control that supports DENON CD players, cassette decks and tuners.

There are 2 kinds, gold and black.
