[quote name='UNITY GAIN' post='1228311' date='May 12 2011, 12:51 AM']So is your average bar band PA system mono then?
As far as I can tell what is being said is that if I use channel/amp A for the audience speakers and channel/amp B for monitors for the band the whole thing will be mono, right?[/quote]
Some are, some aren't. If using A for audience & B for monitors then it's an obvious choice to have everything panned either centre or towards A.
If my band are using monitors then it's either a small 2nd pa system (a small power amp & 2 10" tops) or an active wedge that's hooked up to the main desk (it's only a 16 ch Yamaha mixer, nothing big).
We usually pan the drums around a bit & have a little spread on the rest of the band (no, not primula!).
