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.
Sony Low Noise (1970)
Relative bias: -1.5Relative sensitivity: -1.0dB
THD @ Dolby level: 1.6%
MOL400(1%): -1.3dB

This entry level tape was made from 1978 till 1981. My sample is probably a later one. Performance is very basic, but no worse than early D or UL.

Comparable to Maxell UD 1980. Higher MOL, but also higher noise.
Sony HF-S (1985)
Relative bias: 0Relative sensitivity: +0.5dB
THD @ Dolby level: 0.44%
MOL400(1%): +3.6dB

BHF became HF-S. This tape provides excellent MOL, SOL and noise. At least as good as some versions of AD and UDI, and still quite compatible with IEC 1.

THD @ Dolby level: 0.45%
MOL400(1%): +3.4dB
MOL400(3%): +6.4dB

Very nice MOL/SOL balance, and overall somewhat better than the 1986 HF-S.
Sony HF-ES (1988)
Relative bias: +2Relative sensitivity: +1.0dB
THD @ Dolby level: 0.45%
MOL400(1%): +4.8dB

With performance figures and colour virtually the same, this tape seems to be identical to 2002 HF.
