YAMAHA SOUND STATION Multimedia Amplifier
Model Number: RP-U100
Original Price: ¥60,000

Purchased as an amplifier for watching movies via PC DVD. Later used as an amplifier between the TV, video DVD player, and speakers. It produces sound. There is fading on the back. The knobs on the front are not sticky.

As shown in the photos, the power turns on and all buttons function.
