Theater Solutions TS4D Four Zone Dual Input Speaker Selector Box 4 Pair Speaker Switcher

This is the only device I found for a reasonable price that does what I need - allow the connection of two *amps* into one of speakers. (It supports up to four sets of speakers, but I only needed one... with two amps.) Most other switch boxes support just one amp/receiver, and the few others that do what I wanted are generally a lot more expensive. This seems to be a pretty simple mechanically switched pass-through, and that's fine by me. It works just fine and I don't have to think about it. That's the best thing you could say about a device like this.I'm sure there are people out there like me who have two amps, but in case you're wondering why, I have a newer hybrid tube amp both because it supports Bluetooth and it looks cool, and I use that for music/video from my tablet and phone. This amp only has one input, and it's a line-level input. I also have a vintage Sony integrated amplifier from the 1960's that I use for its low-level phono input as well as for cassette. So I get the best of both the vintage and modern world, but only with this switchbox.

I ordered this control box to enable me to control my outdoor deck and patio speakers, indoor speakers upstairs, downstairs and in my jacuzzi room. They were easy to install and work flawlessly. As a matter of fact it has a lot of additional capacity if I wish to add additional speakers.The beauty of this system is you can have all the speakers on off and even control the volume of individual speaker pairs.Excellent system and great value!

works great, a lot of wiring

Works well but could use better wire connectors. The spring loaded clips are a little fragile but do work.

We needed a way to hook up my a/v receiver and a vintage stereo receiver to the same set of speakers without damaging either one.The Theater Solutions TS4D worked perfectly. Just don’t use too heavy a gauge speaker wire as the terminals won’t accommodate it. I found it easier to hook up the speaker wires to the Theater Solutions selector then run them to the amplifiers.An inexpensive solution to my dilemma.Oh I did use two of these for 2 sets of speakers in the same room.

I received a defective unit. The volume control worked on Zone 1, but it did not work for Zone 2 and 3 (did not try zone 4) - I returned it for a refund. I purchased another brand that costs more, but I need something to work.

This worked perfect. It was not the best I have ever used, but if you are on a budget, or just don't want to spend a lot on your system, this should do the job. Buttons and knobs worked fine, no cracking or static when turning up or down.

No it did not - volume controls don't seem to do anything - need volume on stereo way up to get speakers to work

Does what it's supposed to. We will see how it holds up and how long it lasts. As for now, 5 ⭐

Es un producto para conectar y alternar las bocinas, es muy bueno lo recomiendo .

Funciona bien, le doy cuatro porque puede algo de volumen al ponerlo por el aparato pero por el precio está muy bien

Quality and Price is amazing
