just noticed if I switch from the 900 to the 1200 all the bass dissapears? If Ipull down one of the channels all the bass comes back.?
So one input on its own gives great bass response, as you push up the faders from the desk the other speaker comes on but all bass nearly gone. Tried all combination of leads
speakers etc but as I said with the 900, same set up full sound. I am no electronics person but just need to know so i can take a decision whether to get it fixed.
