I'm referring strictly to SS. Amp has both offset and bias pots. I understand anything up to 50mv offset on each channel is acceptable, 0 being ideal. However, the best I can get is 16mv on the left, 26mv on the right. Bias set at 150ma on each channel. My question is, does the stilted offset skew the bias adjustment? I could just change up the left channel offset to match the right, but not all SS amps have offset pots. I have others with dc servo control and still others with discreet components for the offset but they are never identical on both channels either. So I guess what I want to know is should there be a bias compensation on either channel to accommodate the difference in offset?
Influence of DC offset on bias
Hi everyone. I'm usually an observer here and hopefully learn something along the way. Can someone shed some light on my question of what if any influence or affect dc offset has on the bias of an amp. I know how to check both and have never come across an amp with identical offset on both sides; well within acceptable levels on both sides, but never the same. Also impossible to adjust them to the same level. Does this render identical bias on both sides incorrect in terms of channel balance as it affects your ears? I would greatly appreciate some insight into this.
Thank you
Thank you
