Not sure what a ‘16 bit plug’ looks like. In general, the Sonos Amp is set up to connect a regular set of stereo speakers to it, with a ‘regular’ set of speaker posts (right and left).
You may need some sort of adapter, if this ‘16 bit connector’ is what I’m thinking it may be, or even pulling it off, and connecting the speaker wires directly to an Amp.
The Sonos Amp is designed to power up to four 8 Ohm speakers, although there is a special case only with some Sonance Architectural Speakers where one Amp can support six (3 pairs).
The other option would be, if there is still a Speakercraft (never heard of this) amp to power the speakers, to connect a Sonos Port to feed the line in on it with a Sonos signal. Then you’re not spending extra on an Amplifier when you already have one, don’t have to mess with this ‘16 bit plug’, and just have to feed the Port to the line in. You’ll get one Sonos signal out of it.
This is actually what I have only its just one multi conductor connector if I said that correctly >UNTESTED] SpeakerCraft S8 Multi-Room 8 Zone Speaker Selector Switch W/ Cables | eBay
Yea I was debating on using banana plugs but not sure how to go about that based on the picture I sent
So you don’t have the Amp that connects to that speaker switch?
Are the mzc 66 the keypads installed? Do they seem to work?
If you dig around you can find the manual and it seemed easy to understand — if you have a little audio experience and are willing to study it. The video inputs are essentially obsolete at this point. If you need to reconfigure the system, I don’t know if the software is available somewhere or if it can run on a modern computer.
I expect that the installed speakers are 8-Ohms.
I doubt that many pros will want to deal with this system, unless they just happen to be familiar with it. The risk of some hardware failures now or soon is very high. You could have fully defective keypads or a few bad keys. Maybe bad keys can be restored if you are patient and clever. You could also have issues in the main box.
likely, the speakers are still usable, but of course this is not guaranteed.
If the system seems operational, connect an analog stereo source and test the amplifiers and speakers.
The use of the 16pin connectors suggests that the original installation was done by an experienced pro. This is a good sign. The 16pin connectors will not be useful when connecting modern equipment. Check the documentation as you disassemble the 16pin’s so that you can label the wires in a useful manor.
If that is indeed the case, I’d be tempted (not knowing anything about the speakers at all) to try connecting the speaker ports on the Sonos Amp to the left and right inputs on that switch. Using regular speaker cable. But I wouldn’t want to ‘select’ more than two rooms for output at the same time…and honestly, I’d be nervous with that second room simultaneously. The Sonos Amp isn’t designed / have enough power to push that many speakers, I’d assume the SpeakerCraft MZC 66 is.
Ah, @buzz will take over from here.
Appreciate the help. I’m going to connect an analog stereo source to test the amplifiers and go from there
