what speaker selector switch?

[onthewater1]

i have a pair of speakers in one room and another pair in another room, i want a switch to make one pair will be the left and the other pair the right, then be able to switch back to one pair L R and the other L R. Do I simply need a 2 channel speaker switch? Thanks

Yes, an A/B switch is all you need. Some of them have an A+B option; be careful using that unless your amp can handle the lower impedance . (Some switches can adjust the impedance for the A+B selection.) And if you haven't purchased the amp yet, many have A/B built in.

I don’t think it’s quite that easy. Normally, each pair is L+R. It is most unorthodox to make a pair of two mono L channel and likewise R channel, which is literally what you asked.

Can you explain why that would be remotely desirable as it sounds a bit of a muddled idea to me?

Good point. I didn't understand that either and decided it was just a request for two stereo channels. But I meant to ask and forgot.

You can't just combine two channels "raw", but there are switches for that too (but not an A/B switch). On Amazon look up, "2 in 1 Out Bi-Directional Audio Switcher."

That would a great solution to the typical problem, but the OP has phrased it in a different way, on which I trust they will clarify!

Thanks for the replies!

My open concept small house has a living room, kitchen and back living room without walls separating them. When I'm in the living room ( which is not where I usually listen to music) I want to hear just those two speakers, when I'm in the back living room which is often, I like to hear those two speakers but... when I'm in the kitchen, which is between the two living rooms I thought it would be nice to have the right channel in one living room and the left channel in the other living room so I could hear the separation which I enjoy so much. Hope this clarifies. I love music but not really a stereo tech guy. Thanks!

In summary you want:
Stereo speaker pair A or B or A and B
or Left channel only to pair A, at the same time as Right channel only goes to pair B.

If you find a single switch able to do that, I'll buy it for you.

Seriously, if you really wanted to do it, you could, using multiple switches, appropriately connected.

If so:
Would you know the minimum impedance of each of your speaker pairs?
And the lowest impedance that your amp will be happy with?

 

[onthewater1]

speakers are 4 ohm and amp says use minimum 4 ohm speakers.
Using a multi meter set for ohms set at 20k and connected to speaker outputs of the amp the reading is 34.
does this help?

It just seems like this should be easy. By simply switching the wires on the back of the amp I get the desired effect but don't want to have to pull out the cabinet and switch the wires every time.

is the 2 in 1 Out Bi-Directional Audio Switcher the answer or the Fosi?

Thanks!

That's a guide, keep that figure in mind....

No, that doesn't give you anything meaningful.

Do you?
Presumably by connecting a pair of speakers to the same channel.
Now go back to your first sentence.
Your amp wants to 'see' an impedance of 4 ohms on each of its channels.
If you connect two 4 ohm speakers in parallel to the same channel, the amp only sees an impedance of 2 ohms - and that is not good.

If that's how you've been achieving your (unique) objective, then the answer to your next question:
'Is the 2 in 1 Out Bi-Directional Audio Switcher the answer or the Fosi?'
The answer is no.

Like I said, a combination of switches could achieve your objective, but I wouldn't want to encourage you to drive your amp into impedances that are too low for it.

I'm starting to understand. Thank you!

Hello, I appreciate your time on this discussion with me. I've been thinking about this.I think maybe I haven't been clear on what I'm trying to accomplish.

When I switch the wires in the back of my amp to get the desired affect of left channel in living room 1 and right channel in living room 2, I take the living room 1, right speaker wires and switch them with living room 2 right speaker wires at the amp. So far as the amp is concerned it's wired exactly the same. it doesn't know where the end of the wire goes so there's no change in impedance or ohms correct? Thanks

I'm just looking for a switch to accomplish this so I don't have to pull the cabinet out and do it manually.

Fosi is making nice switches, not as cheap as the passive ones but feature laden. Not sure he'll be able to configure separately L & R and there's the Ohms issue. Maybe there's a bespoke device from another seller. OP can check this out.

Ha ha - See Juzzie Wuzzie@ has got there first! 😊

 

[onthewater1]

I think I have figured out the confusion, my Rotel RKB-D8100 amp has 8 channels so can accommodate four sets of speakers. Clearly I have should have mentioned that at the beginning.

So will the Fosi work for what I want?

Thanks

No, it won't work. You need 4 pairs of speaker selection - see below link

Rotel makes class D, nice. Anyway when I checked the specs, there were four speaker terminal pairs. The Fosi only covers two, not unless they have another model that does four.

I run four sets of speakers from my Rotel amp. The set in the garage and the set in the lanai are fine. It's the two sets in the house ONLY that I want to be able to switch so the Fosi should work correct?

So it's a case of having two sets of speakers on standby and the other two sets working right off the amp. It's complicated 😊
In theory you can have two sets running to the Fosi but leave switched off as it is powered by mains and allow the other two running directly from the amp.

For the sake of simplicity I would go for the device that accommodates all four sets and select the speakers you wish to hear?

thank you! all four sets of speakers are hard wired but they are also all wired to four sonos connects so they are all controlled by my phones sonos app
