I am relatively new to the Control 4 system environment and is trying to help someone solve an amplifier issue. They have two 8 zone amps and one works just fine, from the same source. However the other one shuts down after about 10 seconds. All the zones will appear on the amp and music can be heard and then inexplicably it cuts off. Everything in on a UPS. Any suggestion on how to proceed with troubleshooting would be appreciated. Thanks.
