[QUOTE="Dave Korman, post: 73629, member: 1894"] Re: Headphone jacks The effect of plugging in two sets of phones will vary depending on the impedance of the phones and the source impedance of the headphone amp. Specifically, plugging in low impedance phones may well result in a reduction of level as significant proportion of the available voltage swing will be dropped across the internal source impedance of the headphone amp. If the first set you used were say, medium impedance and then you plugged in a second set that are low impedance, you are very likely to notice the effect. The X32 documentation does not give any specs for the headphone amp; I'll do some tests to determine the characteristics when I get my 'scope etc. out to fix a faulty amp in the near future. [/QUOTE]
