I have installed 14 zones in a large custom home. Each zone consists of the following setup:
Sonos Port → DEA 704D Amp → JBL Pro Control 322C (x4)
I have had a slight buzz in all the speakers, some zones very subtle and some zones extreme. I have tried everything from grounding the rack, ground loop isolators, changing cables, checking software upgrades, changing breakers, outlets, etc … I even considered installing an entirely new breaker box to separate the audio equipment from the rest of the house.
Then I discovered when I change the source of the audio from the Sonos Port to direct cables to my iphone NO BUZZING.
I installed a Sonos Connect Series II and NO BUZZING.
The internet search shows similar issues and dissatisfaction with the Port having noise. I would prefer to use the Port due to is having more features than the Connect, mainly the dual mono option.
Does anyone know if there is a fix to the noise and/or a newer version of the Port coming out?
