    This has never caused me any problems but has baffled me for ages.

    My Pioneer Ax5i receiver is usually set between -15 and -20 on the volume control and this is very loud. Any higher than -15 is just too loud. But my hifi amp is usually set to +40 or above. So is my AV volume set correctly, or should that also be in the +db range. Why is one -ve and the other +ve?

    0dB = full volumn, so anything less is measured as -xdB

    Not quite right actually - 0db = THX ref level on the AX5 (and any THX receiver for that matter). Your volume showing -15 or -20db is actually that figure below THX ref level (which is all channels at 75db from the listening position). If there is a + in the figure, then it's obviously that figure above reference level.
