Hi 

 

I am trying to figure out a way to use my existing set up to project movies in my backyard using a projector 

 

I have 3 Sonos amps 

— 1 amp is for 6 speakers and a sub for the left part of the yard 

— 2nd amp is for additional 6 speakers and a second sub for the right side of the yard 

— 3rd amp if for the family room inside the house

and I have some complementary Sonos moves and Sonos 1 around the house 

 

I investigated the proper setup with bets buy geek squad in 2022 and the final outcome was to get the Sonos bridge and connect everything wirelessly, however I never pulled the trigger and it appears that not the bridge/port and other options are no longer available. 
 

what are my options here ? Wireless? Wired ? Can I connect 2HDMI (amp 1&2) to the projector outside ? It’s a long way for an HDMI cable. Just saying.

You would run analog audio from the projector to a PORT or AMP Line-In, then “Group” this unit to the other AMP’s. Note that there will be a slight lip sync delay for projector audio. This is intrinsic to how audio travels on a SONOS system.

There will always be some lip sync issues in a large system such as this. Sound is pokey, traveling at about one foot per millisecond. Consider listener ‘A’ standing next to speaker ‘A’ and listener ‘B’ standing next to speaker ‘B’ separated by 30 feet, playing the same amplifier output. Listener ‘A’ will claim that ‘B’ is 30ms late. Likewise ‘B’ will claim that ‘A’ is 30ms late, while listener ‘C’ standing at the midpoint, will claim “time aligned”. All three listeners will be correct.

Long story short, I purchased that port and connected it to a turntable in for a three hours. I was trying to hook it up to the system so that we can connect the speakers on the large system that I explained before, and it was not possible because the port is just like another device individually, but no speakers were able to be, added to the port itself to play music on the output from the turntable or any suggestions how to fix this problem

Have you added your Sonos devices to your network? Have you used the Sonos app to group the Amps with the Port? Or, how were you trying to “hook it up”?

All of my devices are connected to the network via Wi-Fi The port is connected to my computer, which I would like to add the speakers to it but when I group it with the other amps, nothing works I guess I’m not using it correctly. I don’t know what’s going on.

For a Room or Group, select  PORT’s Line-In as the source of music.

I tried to hook up the port to a turn table and plugged it in to both line in and out and it seems the port did not recognize the turn table out line.  Are there any specific requirements for the turn table that needs to be used to connect to the port ?

Many turntables require a preamp to get their phono level output to the line level that the Sonos is expecting. Some turntables have one built in, and just require flipping a switch from ‘phono’ to ‘line’, which is sometimes hidden under the platter, rather than on the back of the turntable. But most turntables don’t have one built in, and you need to get an external version. Fortunately, they’re fairly common, and inexpensive.
