- NOOOOOOOOOOO!!!!!!!!!!!!!! Dolby B and C have similar ways of compensating
- for the hiss on a tape (assuming a zero noise source). B compensates by
- 10dB and C; by 20dB. Hence if you record Dolby C, and play it back on Dolby
- B, just use the treble control to cut 10dB (oh well - till it sounds less
- "shrill"), and you'll be all set !!
