2-Channel A/B Speaker Selector - Black With Volume Control, Built In Independent Volume Controls, Accepts Wire Gauges Up To 14AWG

This is an excellent speaker selector. I was a little skeptical at first due to the price being so low (I found others similar to this one that sell for $150 and up), but this one works perfectly for my needs. I’m using it for two pairs of speakers connected to a single amplifier. The sound is not distorted and comes through loud and clear. I also like the option for fine tuning the volume for each pair.

I am using the Monoprice A/B Speaker Selector to drive a pair of rear living room speakers. One source is the rear surround of a 5.1 receiver and the the other source is a more powerful stereo amplifier. I can now choose the source that I want, one for surround sound movies, the other for music. I am buying second A/B Selector to do the same for the front speakers. The volume feature also allows me to balance the levels in the room easily. In conclusion, the build quality of the device is excellent and I do not hear any sound degradation at all. I highly recommend this Monoprice A/B Speaker and Amplifier selector.

I purchased this because we have two sets of speakers outdoors - one set mounted up in our patio and the other set being rock-looking speakers out in the yard (imagine the four speakers forming the corners of a square). Our receiver has A and B speaker connections but due to the difference in the brand and design of the speakers, the set under the patio was much louder. The receiver does not have a way to control the loudness of A vs. B speakers. So I purchased this as a way to control the volume of each set of speakers and get a nice balance. It works, but the unit introduces a lot of loss; with both sets of speakers connected and turned on I had to set the volume in the receiver at 90 out of 100 for a pleasant listening level. I ended up reconnecting the "B" (rock) speakers to the receiver's B speaker output and leaving this unit in for the "A" speakers so it serves as a sort of L-pad. With the Monoprice unit connected there is enough loss introduced so I only had to reduce the volume on the unit by one click. Ultimately, it provides what we need, but not as I had envisioned.

This is a good piece of equipment, although rather larger than it seems like it needs to be. I purchased a small Yamaha receiver for our kitchen and never thought for a moment about whether it had two separate speaker outputs. Imagine my surprise when I was hooking it up and couldn't find a place to connect the 2nd set of speakers! The whole point of buying this nice Yamaha receiver was to save space (it's barely wider than a CD case), but with this switcher, the two take up almost as much room as the old receiver this replaced :-( But anyway the switcher itself works great, and since there are actually "volume" knobs for each set of speakers, I can now choose the level I want in the kitchen and the family room (before I was at the mercy of the efficiency of the different speakers). I put "volume" in quotes because these knobs are not potentiometers but rather stepped switches (this is to be able to handle more power output from the receiver). I would give this unit 5 stars if it weren't for the cheap plastic knobs on the volume controls. And the fact that it's kind of big and clunky. But it does what I need it to and I would buy it again.

Two of the connections fell apart as I setup this machine. Calibration of volume is extremely difficult and not-at-all-intuitive. And the resulting sound quality from my speakers was spectacularly degraded. The many positive comments here suggest that if you are sophisticated with speaker technology, then this item works for you. For me, this item went to Goodwill the next day ... and yes, I feel guilty about my "contribution" there.

This is a solid component that solves a common problem at a reasonable price. I already had a distribution unit, but it sent the same voltage to each selected speaker set. In order to reproduce enough volume from an outdoor pair, it had been necessary to disengage the indoor pair, because the indoor volume would be unacceptably high. With this component in place, balancing the two pairs became simple. I doubt I’ll often touch the volume limiters going forward, and cutting out the patio pair when not in use is a simple matter of pushing one button. At least from external observation, this is a really well-made component, much heavier than I expected with few plastic parts. I disagree with other reviewers that the speaker wire connections are cheap or inadequate. They’re are merely designed to be semi-permanently connected with screw down closures, which is precisely what you want, in my opinion. I cannot inspect the internal circuits without disassembling the unit, of course, but there is no discernible tonal drop-off or detectable distortion from incorporating the device. The cabinet remains cool after hours of use. I have every reason to think that the internal quality is as high as the external. Highly recommended!

I bought this A/B speaker switch to replace an old Radio Shack one that occasionally would cut out a speaker while playing music. This Monoprice A/B switch is great. It allows you to have two different amps as inputs and two different sets of speakers. You can also control which input maps to which output. I used it with one Stereo Receiver/Amplifier as the input and a couple of pairs of speakers in my garage and patio. I love that I can control the volume of each output. Pros: * Two independent inputs and two independent outputs. * Individual volume controls for each output. * Well made and sturdy. * Comes with room labels. They could also be used for your cables. Cons: * Cannot use speaker wire larger than 14 gauge. Remember the smaller the gauge number the thicker the wire. 12awg is larger than 14awg.

I was in a situation where I need to use one amp with single speaker outputs to drive two sets of speakers. Unfortunately the speaker impedances are different and so they play at different loudness levels at the same amp setting. I found this product and figured for the price, why not try it; I know Monoprice and they'd never sold me a bad product before. When my selector arrived it was in pieces. The three long screws on the bottom and their nuts were loose or out. I took the metal casing apart, located the missing parts and re-attached them without issue the put the whole thing together. Hookups are straight forward but it would be nice if there were a little more room; one stray strand of speaker wire and you could short out both speaker channels. I only needed one input, two output so I've got room to grow with this two input system. Amp to input A. local speakers to output 1, remote speakers to output 2. Front source selectors to "A", turn both outputs "ON" and turn to full volume on the switch. A quick test or three with my DB meter at both speaker sets and turning the local speaker volume down by about ⅓ and output level of both pair is even enough to suit my needs. I don't think I could have build a rig for less than this and I get an all metal enclosure with dual inputs to boot.

I’ve been using it for over two years now to run two sets of speakers and it’s flawless in every way.

ce produit est parfait pour controler le volume entre mon amplificateur de guitare et les haut-parleur ainsi je peux équilibrer le volume entre les deux pour un petit local où je dois respecter un certain niveau de puissance sonore pour mon environnement c'est à dire pas trop élever ce produit est parfaitement adapter pour le faire de façon parfaite et précis.

muy útil para lo q lo necesitaba cubrió mis expectativas

This was bigger and heavier than I was expecting, which is a good thing and it works well. One minor gripe is the terminal block on the back is a quite small so it was a bit fiddly hooking it up.

Buen material, lastima q todavía no lo he podido usar ya que pensé q se conectaba a la luz y servía como amplificador, me equivoqué de producto
