My XPA-5 was purchased new 4-5 years ago. I never hooked everything up until recently. My wife and I were playing acrobats half way in the air hooking up speaker wires. In one occasion +/-ve of one set of speaker wires touched each other. I saw a SPARK. I saw a "pop". It happened twice. Protection kicked in. Amp was shut off. I thought it was safe. Then we realized that channel stopped working. I switched speaker wire to confirm the finding. I wrote Emotiva to no avail. Can someone offer some help pls? Thank you in advance.

Fuses are the first place to start after cleaning up your loudspeaker connections.

You can open it up to check the fuses or try calling Emotiva directly. It's faster than emailing. And you might want to check the RCA/Balanced output switches on the back to make sure one didn't inadvertently get knocked out of position.
