im trying to set up my geq on my yamaha rx-v465 and need some help. the problem im having is that i cant change a geq setting for all of the speakers at the same time, i have to choose FL,FR,C,etc.. then change the setting. how i set it was i put in a cd, set the receiver to 2ch stereo, unplug the right speaker, tune the left one, then copy the setting for the rest. is there a better way of doing this because i cant set a eq for 1 speaker when all the other ones are playing, and my method isnt very efficient when i just want to make a quick change
