I have often pondered this question,maybe some of you can help.On my Denon each channel has volume adjustment from -12 to +12.If this is set to +12, max output,would this signal be over driven?If it is set to -12 is there excess noise?If it is set to 0 am I losing lot,s of volume for no reason?So what is the max ch level vol. from -12 to +12 for cleanest signal,does it matter? p.s. with this ? I am not concerned with calibration,Thanks in advance!
