Panasonic RQ2102 is an audio cassette player with both playback and recording capabilities. Besides the built-in microphone, it can be connected to an external microphone or another sound source. The device can play both sides of a cassette tape in sequence thanks to its auto-reverse function. It can also fast forward and rewind the tape, as well as pause the playback. The recording can be started both at the beginning of a blank tape and during playback. It's possible to monitor the recording through headphones connected to a dedicated jack.
