DENON 3800 red blinking protect mode

Hi, 

I have faced a production incident where a power surge tripped the entire setup below (power got disconnected, breaker didn't got tripped but the power source suffered an outage for few seconds disrupting the setup below and after that DENON receiver went into the red blinking mode (protect mode) and faced a complete shutdown, I tried doing a complete reset by following denons guideline, that did restored the system but wiped all the existing configuration - upon enabling all the channels and speaker setup to back to its orginal config, DENON again went into protect mode and faced a shutdown. Please advice what you think may be going on. 

The architecture diagram is attached with this email. here is my setup below: 

• Please note I have bought EMOTIVA XPA 3 GEN3 and EMOTIVA BAS X A2 via emotiva, AV Receiver 3800 from DENON, AudioFiles 4 ZONE ALEXA powered speaker selector, DENON 9080 Front/Center Speakers, Harmon Kardon 2 small and SubWoofer

   

• Please refer to the architecture drawings attached: 

   

• Emotiva XPA 3 GEN3 are only powering BP 9080 and CS 9080  on Zone1 of DENON 3800 Receiver 

   

• Emotiva BAS X A2 is powering all zone 2 outdoor speakers Definition Technology DT AW6500 

   

• Power Source distriubuting the power is from sundovo (power conditioner -> PMX-3300 Power Conditioner/Sequencer (Black Panel Version)
