I'm having problems using a Mackie CFX12 and Mackie Thump 12 active speakers as a PA in a
school. I set this up every week to run a 'showcase' in school usually using 2-3 mics.
It's always a race against time but I try to soundcheck. I set the main mix fader to 30,
have the channel faders down and the channels muted. The channels are assigned to sub 1
and 2 and they are set to unity. I get the performers to sing and adjust the gain till it
peaks and back it off a bit. I then unmute it and raise the fader to unity. When I try to
raise the main mixer fader to an acceptable level, I can never get it high enough without
getting feedback. The space is very uneven by the way.
Am I setting it up
wrongly or are there any suggestions as to how I can improve this?
Any advice would
be much appreciated!
