First things first, it's a Numark DXM09..
What happens is i will have a mix in, and then one of channel 2 will cut out and only play out of the left speaker (its the channel for the left).. The problem fixes if you whack the gain up full then bring it back to normal, but then its louder?!
Its annoying because it used to do it on channel 3, then it fixed itself.. and now this!
Mixer is at least 2 years old.
Thanks in advance
