Magnetic Reference Lab 243-287-512-109 1/4" Calibration Alignment Tape with Chromatic Sweep (1 kHz, 10 kHz, 100 Hz - 355 nWb/m)

Short Calibration Tapes with a 1 kHz tone for calibrating gain, a 10 kHz tone for calibrating phase (azimuth adjustment) and the highfrequency equalizer, optionally a 100 Hz tone for the low-frequency equalizer, and a Chromatic Sweep for verifying the response over the whole audio range. All are recorded with fringing compensation; with 250- or 355-nWb/m reference fluxivity; and 4- or 8-minute duration at a single tape speed, or 5.5- or 11- minute duration at two speeds, 15 and 30 in/s.
