What does S.L.C. mean?(in NAD 3140 amplifier)
This may be a silly question, but, despite nearly 40 years of servicing radio &
audio products, I don't know what S.L.C. stands for, and can't work it out from the amplifier schematic. In addition I'm not too sure how the 'soft clipping' circuit in these amplifiers functions. Having just replaced transistors Q627 & Q628 in a 3140 which was distorting only with the 'Soft Clipping' switched on,
with 2 x 24v zener diodes(as per the service bulletin), I cannot now perceive any difference between 'S/C 'on' and 'S/C' 'off'.
