2 Way Speaker Switch, 1 in 2 Out Way Pair Stereo Speaker Selector W/Volume Control Metal Non-Slip Box - Black (61052), 9.0 x 3.25 x 1.5

No problems. Functional, it's doing its job in my home studio.

I bought this to run a 3rd set of speakers to my outside deck from my stereo system which only has an A and B for 2 pairs of speakers which are in use inside. Super solid with some weight, very well built. Easy to set up. I was shocked that after hooking this up, my system seemed to sound better and added some volume to all the speakers. I love the separate volume control which I'm using to lower the output on the rear speakers. Gives the soundstage a really good balance of while keeping my front speakers as the main stage. Highly recommended.

This control works really well. It is heavy and well constructed, the connectors are solid, the switches and speaker 2 volume control are heavy duty. The only thing that kept this from a 5-star rating is the somewhat confusing operation - If both sets of speakers are set to ON, they are both on. If one is ON and one is OFF, then that is exactly what you get (either can be off). However if they are both set to OFF, speaker 1 remains on. This happens to be exactly what I wanted, but might be confusing. I have my speaker 1 set as JBL L-100s which have a somewhat muted tweeter. I placed Advents on top as my speaker 2, set to extended high range. I can dial in just enough high response with this controller's volume knob to get exactly the sound I was looking for.

I bought this to replace a stereo L-pad from Radio Shack from the 1970's which was starting to fail. I had the L-Pad installed in a lightweight project box that would slide off my credenza if bumped. This is SO much better. This unit is metal and has some heft to it. The pads underneath keep it securely in place. I use it to attenuate (blend in) some metal Super Tweeters that run in parallel with my main speakers. Aesthetically, this device is much nicer than my old project box, and is easier to operate.All the controls and inputs/outputs are clearly and neatly marked in white font. The binding posts are metal and are solid. Initially, I was going to use banana plugs, but realized there were holes in the sides of the posts which allow the speaker wires to be connected directly, and screwed down securely using the caps. The volume control only works with the B set of speakers, which is how I am using it. The A set has a switch, like the B set, to turn the speaker sets on or off. For my application, I did not need to connect any speakers to the A side.I am not sure why this unit was flagged as frequently returned. Thus far, this controller is working great, exceeds my expectations, and is worth its cost.

It cleared up the problem with 4 sets of speakers, both indoor and outdoor.

Don’t buy!!!! No sound on speakers. As I was troubleshooting the clasp that holds the wires in all broke. Ridiculous. Don’t waste your money.

Only had it for a few days so far but works good. It's in a sturdy metal case so I'm assuming it will last a long time. Needed something to use with my sonos amp so it could be used with multiple "zones" No issues found so far using it with both zones on or only 1/no zones on (obviously better to not have anything playing if both zones are set to off). Terminals take up to 14 gauge speaker cable. It would be nice if it had terminals so I could use banana plugs but that would probably add to the size/cost of the unit.

This device works, but there is a noticeable loss of audio quality when using it vs bypassing it.
