The HK 3390 was born to make beautiful music and, like all specialists, it's very good at what it does. It features high-current, ultrawide-bandwidth amplification, a signature Harman Kardon technology that delivers all the subtlety of an original musical performance, whether reproduced from vinyl or your MP3 player of choice. But even specialists enjoy a change of pace from time to time. So the HK 3390 also features four high-quality composite video inputs, and convenient front-panel inputs for video games and portable audio players. Bandwidth @ 1W (-3dB) - 10Hz - 110kHz Audio Inputs - 7 (1 on front panel); Video Inputs - 4 (1 on front panel); Video Outputs - 2; Input for turntable
