PIONEER A-20 black

The Pioneer A-20 Stereo Amplifier uses symmetrical design and minimal signal paths to provide you with excellent sound performance with minimal noise. If you often listen to music at low volume, you will appreciate the Loudness feature which boosts the bass and treble frequencies, so that you can enjoy your music with all the details every time. There is also a Direct switch to bypass all non-essential signal processing and to ensure the most accurate and maximum reproduction.
The polished aluminium front panel features the classic controls for the stereo amplifiers. You can control the volume, bass, treble, balance and input switch here. Other several buttons complement the functionality of the equipment fully. There is also the possibility of connecting two pairs of speakers with the possibility of switching A/B and Bi-wiring. The rear panel feature inputs SACD/CD, Aux-in, Network, Phono (MM), Tuner, and Recorder. You will certainly appreciate your listening experience with the comfort of the provided remote control.
