Suitable for Playback Output Level alignment of Pioneer (ST-F1250 etc.) and Philips Cassette Tape Decks. Set Playback Output Level of each channel to match with "0 dB" marks on the "VU"-meter's scale.

The Cassette Tape is a Full-track Master tape (not a copy). Cassettes are recorded OFF SHELL using an OTARI 0.15" (3.81mm) Reel-to-Reel MX-5050BIII-F-P4 Production full-track tape recorder and professional test equipment. The Capstan motor of the tape recorder is controlled by digital Quartz- Locked PLL. This can work at standard speeds with 0.01% accuracy, and at any speed from 1-7/8 to 30 ips using an external clock generator. (If required a cassette can be recorded at 30 IPS)
Reproduction or Playback Head of the tape recorder is a 4-track 4-channel head to measure Level unevenness @ 400 Hz.
PLEASE NOTE. Level unevenness is checked totally across the tape (not along the tape) before recording. Tapes with difference in Level more than 0.2 dB are discarded
Reproduction Equalization is calibrated using a Constant Magnetic Field Transducer which has been designed by GennLab
Duration 10 min recorded at the BEGINNING of the Tape from 00 min 10 sec to 10min 10 sec
