Panasonic RQSX11 is a stereo cassette player with various features such as auto reverse, Dolby noise reduction, and tape program sensor (TPS).

Auto reverse allows for continuous playback with both sides of a cassette being played back automatically. Dolby noise reduction enhances the sound quality by minimizing background noise, particularly noticeable with higher volume listening or with lower quality tapes. The tape program sensor function makes it easy to find the beginning of a song by automatically skipping silent sections of the tape during fast forward or rewind.
