need switch to alternate L & R channel in different rooms

[onthewater1]

I’m going to try this one more time…but this time I’ll try to include all the necessary information...i hope.

I have a Rotel RKB-D8100 amp with 8 channels pushing four sets of speakers.
I have two speakers in room 1 and two speakers in room 2, the other two sets are not important for this discussion.
When I’m in room 1 I have stereo sound, when I’m in room 2 I have stereo sound. In my open concept house between rooms 1 & 2 is my kitchen. When I’m in the kitchen I’d like to have the left channel coming from room 1 and the right channel coming from room 2.
I can accomplish this by manually switching the left wires for room 1 with the right wires from room 2 in the back of the amp but it’s inconvenient.
I’m wondering if anybody is aware of a switch that would accomplish this?
The Russound AB-2.2 doesn’t do this.
Not sure if this is pertinent but just in case...I have four sonos connects connected to the four sets of speakers all controlled by the sonos app in conjunction with spotify on my phone.
Thanks!

The switch that Vincent has linked to will do what you want.
It is wrongly described in the description as a 12 pole switch.
It is a switch with 12 contacts.
But, importantly for your purpose, it is actually a 4PDT (4 pole, double throw) switch.

You'd need to be handy with a soldering iron - if you're up for that I'll draw you a wiring diagram.....but it won't be pretty.

that would be great, thank you!!

It's past midnight now, so later today for the wiring to the switch

If you go for the switch, the use of the usual 2.5mm minimum stranded cable won't be practical for your soldering.
Ideally you want thinner, solid core, through the holes in the solder tags , maybe run to 8 chassis sockets (on the same box) for plugs from your amp and speakers.

The switch depends on two stereo outputs from your amp (we'll call them outputs A & B) being on simultaneously.
Then you can have stereo to both rooms OR Left in one room, Right in the other, depending on the 2-position switch.

...If you wire that switch like this:

You will end up with this:


I went with the flat toggle:
But the switch body is the same as yours would be:
Whites are the link wires.
(You can see why thin wire is a good idea)

That does your 2 speakers left in one room, 2 speakers right in the other.
But if you could settle for just one speaker playing each channel in each room - you could do it with a ready-made, source to A or B switch box.

Thank you Gray. Greatly appreciate your time, diagram etc!!! If your ever in Naples FL, US, beers on me.
Thanks again.
