This is a compact MD recorder from the "Avino/PRO-7 series" released in 1997, which was a high-end model that cost 60,000 yen when it was first sold. The sound quality was so high that it was indistinguishable from a CD upon first listen, thanks to the "20bit REC D.R.I.V.E." technology, making it incomparable to the more common MD component systems. Basic operations such as power on, disc loading, playback, disc ejection, and digital input recording were all confirmed to be working. However, since there is no remote control, the operation of analog input recording and erasing could not be verified. There are two spots of dirt and slight warping on the top panel.
