2-Way Amp Amplifier Receiver to 1 One Pair of Speakers Selector Switch Switcher Splitter Combiner

It's a rather long story and I don't want to bore you with too many details, but in our upstairs den, I now have two amplifiers, both of which I like very much.One is a Yamaha A-S300 2-channel amplifier and the other is a new Onkyo TX-NR696 Smart AV Receiver.I received the Onkyo earlier this month and I could have replaced the Yamaha with the Onkyo but I really like the sound quality the Yamaha delivers and I did not want to do that.I now wish to use the Yamaha with music only and I wish to use the Onkyo for watching movies (in conjunction with an LG video projector) as well as listening to music on occasion. (I had previously used the Yamaha for watching movies but, as it has no HDMI input, running my Blu-ray and/or DVD player through it and combining all that with the projector was rather cumbersome.)My Yamaha amplifier is attached to two Mordaunt-Short Pageant Series II loudspeakers (originally purchased in 1980 but still producing superb sound quality). When I received the Onkyo earlier this month, I attached it to two Dayton Audio MK402X bookshelf speakers (also superb). I thought that this would solve my "problem" (as to what to do with two amplifiers in the same room).Unfortunately, due to space limitations in the room, the Dayton Audio speakers had to be placed in the stereo equipment stands and this proved to be totally unsatisfactory. The stands would vibrate (buzz) during scenes with low bass sound in movies as well as music with deep bass notes (especially organ music).So, even though the Dayton-Audios are amazing speakers (they are the very best small bookshelf speakers I have ever heard), they had to "go" in this particular situation.I searched here on Amazon for a device which could combine the output from the two separate amplifiers to one pair of speakers (the Mordaunt-Shorts) and I found this < 2-Way Amp Amplifier Receiver to 1 One Pair of Speakers Selector Switch Switcher Splitter Combiner > sold by Specialty-AV.Frankly, it is EVERYTHING for which I had hoped.It is very well-designed, very well-made, and performs in a superb fashion.Another reviewer here commented that the ports are cheaply made and, more importantly, are too close together. That has NOT been my experience. I am using two types of connectors: speaker pin connectors (from this device to the speakers) as well as banana plugs (from the amplifiers to this device).The AmazonBasics banana plugs are the "fat" type yet they do not touch each other. The speaker pins, though of the "slim" type, also work perfectly and, fully connected to their respective sockets, are not even close to touching (that applies to the connector bodies as well as the pins themselves).The cables I am using are 16-gauge speaker cables (connected at both ends by the banana plugs) except for the cables actually connected to the speakers themselves which are 12-gauge speaker cables (connected at both ends by speaker pin connectors).All I can say is that everything works perfectly. I have no doubt that the other reviewer experienced the problems he described, but this has NOT been my own experience.Is the unit overpriced?At its current price of less than $60.00, I truly don't think so. It actually has little competition and it is, as I have written, very well-constructed. Especially the front switches for selecting the amplifiers are of the type which do not get "noisy" in use (at least in my own experience over many years). The design is also exemplary. The connections are conveniently placed and are easy to use. I had absolutely no difficulty in connecting the speaker pin connectors nor the banana plugs.For all that you get, not only do I think that this unit is not overpriced at all, I really think that it is a relative bargain.Therefore I must say that, in conclusion, I am completely satisfied with this device and I think that, if you have need for such a device, you will be completely satisfied too.I give this unit my highest recommendation.I do apologize for this rather long review. and I thank you for reading it. I hope that it has been of some help to you.Lawrence H. Bulk

Got this in the mail today and my first impression was that it seems incredibly well built, at least from the exterior. Banana plugs are standard size and I had no issues using audioquest bananas or crutchfield. Both had a snug fit. For bare wire there were sizable holes, but what I bought it for was its banana plug friendly setup.It works phenomenally! The way the switches work I was able to run both amps and test each on different speakers. It might seem silly to those that complain about two vs one switch but I find 2 switches the smarter choice considering flicking two isn’t really different from switching one and it adds functionality to hear two amps side by side.The main reason I bought this, is to switch my mains between AV Receiver and Stereo Receiver. Before this I had to weigh either manually unplugging and replugging speakers (gross) or having a second set occupying more space (and blocking the TV) which is what I had before this unit (I live in a small apartment)This thing seems like an absolute life saver. It seemed a bit expensive for what it is, but honestly seeing it in person I’m reassured that it was well worth the money as it doesn’t seem at all like they skimped on the details. It feels very sturdy and doesn’t look half bad either.

When I acquired a Technics Network CD player with its own amplifier, I was faced with the question of how to integrate it into a 5.1 system where my current home theatre receiver/amplifier was using all of the speakers. The solution was this box, to which I connected my pair of front speakers and both amplifiers. Now I can choose whether the CD amp or home theatre amp is using the speakers with a flip of the switch. (The box is on the shelf above the CD player in the photo.)The box is small but solid and heavy enough such that the six wires attached to the back do not upend it, unlike a somewhat less expensive similar device I saw elsewhere. The construction of this box is excellent, and I see it lasting the lifetime of my system.The one thing it does not have (but neither does any other switchbox I found) is a set of RCA inputs with an output for my subwoofer. For that, I had to buy a separate switch box. But everything works great.

This is a very simple product that meets a niche need. In my case I have an A/V receiver that’s I use watching movies, and a high end stereo amp system For music and I want to use the same set of front stereo speakers (an expensive pair of JBL’s).The switching box has a built in 100 Ohm load at each set of amplifier inputs just in case you accidentally had the unused amplifier On. Solid state amps are designed to operate safely with no load, but many classic tube amps cannot operate with no load, they can self destruct in that case. The built in 100 Ohm loads are enough in most cases to prevent the problem while wasting only a small amount of your audio power in an 8 Ohm system.The box seems sturdy enough. The connectors on the rear can either be used as binding posts with plain end speaker wiring or with individual banana plugs - but only straight in bananas, no right angle bananas. The terminals are fairly close together.The switching allows you to theoretically separately select the Left or Right from the A or B amplifiers. Not really a practical function, but I understand why it’s wired that way - As is the separate switches are DPDT (both the positive and negative sides of the signals are switched). 4PDT high currents switches are not that available. So you have to throw two switches, one for Left one for Right. It’s not a big deal.The device is exactly what I needed. The quality seems good and the price seems fair for what it is.
