 on proper cooling procedures. Check the signal lights on the rear of the 

amplifier to see if the signal is overdriving (the clip light flashes red frequently). Overdriving 
the amplifier for extended periods of time can result in a thermal shutdown. 

Output sound is distorted or cracking. 

 

Check all cables for damage or loose connections and reduce the gain on the input signal at 
the mixer or preamp level. Replace the cables and loudspeakers temporarily to see if this 
resolves the problem. If problem still exists, contact your Authorized Dealer for service.
