Customer Q&A

Crutchfield asked: Why did you buy this?
The one I ordered from Amazon was terrible. I heard Crutchfield has quality electronics. I will provide kudos if true. Thanks [ Stephen  Sep 13, 2019 ]
To switch between 2 amps and 1 set of speakers. [ Michael  Aug 07, 2019 ]
Bought this to hook up a second class a amp to my system [ Robert  Mar 18, 2019 ]
I have outside speakers, and my old A/V receiver had the capacity for 9 speakers, the new A/V system I purchased only had room for 7 speakers, so I needed the A/B switch to accomodate my outside speakers. [ Robert  May 28, 2018 ]
Doug (4342186120) recommended it [ Theresa  May 05, 2018 ]
Have one, like it so much, I ordered a another one. [ W  Mar 07, 2018 ]
It was suggested by Nemo and I have another Russound product in a more complex set up (two receivers and two sets of speakers) that works perfectly. Thanks for the help. [ Charles  Mar 05, 2018 ]
Simple [ Stuart  Nov 26, 2017 ]
I had a somewhat complicated situation trying to feed multiple sets of speakers from one receiver and OZZY was a HUGE help in steering me to exactly what I needed to solve my problem!!! [ Joe  Aug 04, 2017 ]
I trust Crutchfield to carry a good product line, and this item meets my current need. [ Terry  May 04, 2017 ]

2 questions already asked

can you use two sets of speakers from one source at the same time or do you have choose between A or B?

If Russound AB-2.2 is being used to switch 2 sets of speakers from one source, only one set of speakers can be used at a time. This device is actually used to switch two sources or amplifiers between a set of speakers, a speaker selector would be more inline with what you're trying to do and some can run more than one set of speakers from a source at a time when properly hooked up.
[ Jesse  Feb 02, 2018 ]
The box itself is one or the other.
[ JEREMY B  Feb 02, 2018 ]
It's designed to play one or the other. You cannot play two sets of speakers at the same time. This is to avoid the situation where you have two sources feeding one speaker at the same time.
[ Stuart  Feb 02, 2018 ]
Can I still use this with two separate stereo systems which are bi-amped with active crossovers on one pair of speakers? Thanks.

If I understand you correctly you have 4 speaker wires for each speaker. The AB 2.2 can only switch two stereo pairs to one stereo pair output. You would need twice as many connections to do what you want.
[ Phillip  Feb 23, 2016 ]
The AB-2.2 selector allows you to power a single pair of speakers with either of two amplifiers (There are two input channels to the AB switch and one output channel.) The selector switch isolates one of the input channels (amps) preventing them from both being connected at the same time. I suspect that the AB-2.2 may not be exactly what you are looking for. Russound makes other products which might be closer to what you need. As a note, the internal construction of the AB-2.2 product is solid, but the wire connectors on the box are very small, probably 16gage or less.
