Audio Cassette Level Calibration Test Tape

Brand new test tape for checking the playback levels of your cassette decks.

Specs:
- 315 HZ, 0 dB tone (IEC PRAGUE 1981 Spec)
- Simulated to produce results like the Teac and Sony test tapes.
- Recorded on reel-to-reel duplicator
- Level tolerance: +- 1.2 dB

Notes
This test tape is recorded in stereo quarter-track mode, not full track. It is not 100% accurate because of potential head height misalignments. The results when used with 4-track machines will vary a bit due to a different head configuration on those machines. It will not work for 6 and 8-track machines. This is an amateur tape for quick checks, not a pro laboratory-grade tool.
