we have 24 channel mixture gl2400 but i dont know use of foh & rev button &what are there functions ,so kindly give explaination how to use it thanx
RE: question regarding gl2400 - Posted by: John Gentry on 11/30/2010
The rev buttons on that console, enable you reverse the function of the aux sends and groups sends …as in the case if you chose to use the console as a monitor console , the aux mix is now sent to the rear group xlr sends ( whcich has inserts etc. and the groups are now control with the rotary dial control. This is so you have all fader controls to control all of your monitor mixes. Hope this helps. if you are using this as a FOH console you will not need to use this function.
