I have two 1210s and a behringer ddm4000, i have 2 hifi speakers for now (untill i get my new amp and speakers) plugged into the monitor ports on the back of my mixer and my right turntable plays out of both speakers and the left turntable plays out the left speaker but sort of muffles on the right speaker and i cant figure out why it i have tried swapping round the turntables..etc no luck. do you think it will work fine when i get my new power amp and speakers?
