How can I switch 1 source to two amps/receivers to 1 set of speakers

[contoursvt]

Ok I know it sounds odd but I'd like to conduct some kind of listening test where I can, while having the music play, switch between two amps or receivers and have the output go to the same set of speakers? If I can do this via a remote, that would be good. I've seen plenty of speaker switch boxes but that doesn't help me. Neither does an input selector because the speakers wont switch over.

Its basically something to switch between two amps which have been adjusted to the same volume level and seeing if there is much or if any audible difference between the amps themselves. Better if a friend connects the inputs and doesn't tell you what you're switching between (ie source 1 or 2). Any help appreciated.

Copy the source to both amps with a simple Y connector. It's not the "best" method possible, but it will work for 99.9% of the reasons you might want to do this.

Then, build something like my A/B switcher:

You would connect the speakers to the common connector and each amp to the A or B connectors. I could consider loaning this to you or selling it if needed.

Thanks guys. Actually I'm kind of interested in that QSC unit. Might definitely do the trick. PM sent

Couldn't you get a 3 or 6 channel Adcom speaker selector, except use the "in" on the selector as the "out" to the speakers, then run one amp to "A", and the other amp to "B"? You can get those selectors on eBay for less than $30 usually. You would need 2 preamps going this route.

Hmm never thought of that, but I think I will try the QSC item and see how it goes
