I plugged an Alesis sr18 into two channels and everything was playing great.
The sr18 was running on batteries and they weren't going to last very long so, I plugged in a power supply. The wrong power supply and the xp1000L let out a screech. Now the first speaker output doesn't work. The second and the monitor speaker outs work.
Do you think I blew a fuse? Is this something I can fix?
