DENON PMA-390 Integrated Amplifier
Product Details
This is a DENON integrated amplifier PMA-390.
This is a valuable early model from Nippon Columbia.
An integrated amplifier that pursues a genuine sound quality exceeding its class, featuring a large toroidal transformer.
The power supply unit employs a large toroidal transformer with minimal magnetic flux leakage.
Furthermore, by adopting a low-impedance volume control, the impedance of the volume adjustment circuit is lowered, preventing deterioration of S/N ratio and frequency characteristics at general listening levels.
It is equipped with a tone control circuit that allows for boosting of low and high frequencies, and loudness enables powerful playback even at low volumes.
It also features a source direct switch, which, when turned on, bypasses the tone control circuit for purer playback.
It is equipped with a wide-range equalizer amplifier that can switch between MC/MM.
[Condition]

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
