INDEX OF ALL CASSETTES

Maxell UR (1994)  (what the deck was calibrated for)

Relative bias: (reference)
Relative sensitivity: (reference)
THD @ Dolby level: 0.42%
MOL400(THD=1%): +3.4dB
MOL400(THD=3%): +5.3dB
MOL1k(THD=3%): +2.9dB
SOL10k: -1.3dB
Bias noise: -49.5dB, -52.5dB(A)
Dynamic range: 57.8dB

Concerning sensitivity at 400Hz this UR seems a close match for the 1981 and 1994 IEC I references. At 10kHz UR sits between the old and the new reference.

Fuji ER (1982)

Relative bias: -3
Relative sensitivity: -0.2dB
THD @ Dolby level: 1.0%
MOL400(1%): 0dB
MOL400(3%): +2.4dB
MOL1k(3%): +2.0dB
SOL10k: -1.7dB
Bias noise: -50.4dB, -53.8dB(A)
Dynamic range: 56.2dB

Fuji FR-I (1982)

Relative bias: -1
Relative sensitivity: +0.5dB
THD @ Dolby level: 0.46%
MOL400(1%): +3.4dB
MOL400(3%): +5.9dB
MOL1k(3%): +5.1dB
SOL10k: -0.4dB
Bias noise: -49.2dB, -52.9dB(A)
Dynamic range: 58.8dB

There was a lot of difference between side A and B, possibly indicative of wear and azimuth instability. Bias was probably set a bit low in order to compensate for treble losses. Otherwise this would have been an excellent tape.

Fuji DR (1985)

Relative bias: 0
Relative sensitivity: -0.9dB
THD @ Dolby level: 1.0%
MOL400(1%): 0dB
MOL400(3%): +3.2dB
MOL1k(3%): +3.0dB
SOL10k: -1.0dB
Bias noise: -48.5dB, -51.8dB(A)
Dynamic range: 55.0dB

Fuji DR-Ix (1990)

Relative bias: -2
Relative sensitivity: -0.4dB
THD @ Dolby level: 0.82%
MOL400(1%): +0.7dB
MOL400(3%): +3.4dB
MOL1k(3%): +2.9dB
SOL10k: -1.6dB
Bias noise: -49.7dB, -53.2dB(A)
Dynamic range: 56.6dB
