Audio Cassette Level Calibration Test Tape

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

Specs:
- 315 HZ, 0 dB tone (IEC PRAGUE 1981 Spec, approx 250 nWb/m)

Level tolerance: +- 1.2dB

Notes
This test tape is recorded in 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.
