The Panasonic RQ-L400 was a portable monaural cassette recorder released in the 1990s, specializing in recording functions.
It was a "thin and multi-functional" high-end model among the lineup at the time, and was popular mainly for recording meetings, language learning, and voice memos. The main features are as follows:
1. Auto Reverse (both recording and playback)
Unusually for this size, it supports auto-reverse for both recording and playback. There's no need to flip the tape, and when side A is finished, recording on side B automatically starts, making it less likely to be interrupted during long meetings.
2. Voice-activated recording (VOS) and fast-forward function
In addition to the "VOS (Voice Operation System)" explained earlier, it is equipped with a **"fast-forward function"** that speeds up playback.
This is very convenient when you want to check the recorded content in a short time.
3. Microphone sensitivity switching
The microphone sensitivity can be switched between "long distance (for meetings)" and "short distance (for memos)" with a switch on the main unit.
Long distance: Suitable for picking up speeches in a large conference room.
Short distance: Suitable for voice memos and interviews where you record your own voice.
4. Recording monitor & LED indicator
Recording monitor: By connecting earphones during recording, you can listen to the sound being recorded in real time.
REC lamp: During recording, the LED flashes and lights up in response to the sound, so you can visually confirm that the recording is correct.
5. Other specifications
Power supply: AA batteries (2) or AC adapter.
Built-in speaker: You can play audio from the speaker on the front of the unit without earphones.
Size: Compact design, palm-sized, designed to be carried in a chest pocket, etc.
