OSD Audio 100W in Wall Volume Control Impedance Matching for Home Speakers, Rotary Knob White SVC100

What I liked 1. It came with different color face plates - wasn't a separate purchase 2. The input and output wiring blocks were different colors - great aide to preventing miswire the volume control. 3. it works! What I didn't like 1. the wiring blocks once installed put the wires in towards the center of the volume control pressed up against the transformer creating a 90 degree angle to get the wires to clear the cut in mud ring. This puts strain on the wires to the wiring block, as well as strain on the wiring block to the mounting pins. 2. the exposed circuit board. this is potentially a serious issue if your installing in a commercial environment that have metal mud rings. Definitely not cool What I'm on the fence about The quality of the electronics is good, the nob and potentiometer doesn't feel like quality. But then again these aren't Niles or Russound and come in a 1/4 of the price. You get what you pay for.

This volume control works perfectly. I replaced my 19 year old volume control that was making a distortion sound and is outside on my patio. This one was the same dimensions exactly so it fit right in the receptacle. The connectors are clearly marked input and output and are removable so you can make your connections easily and then connect them up to the unit. It also comes with three color knobs and cover to match your decor. Very satisfied as my sound is back to high fidelity. The instructions were clear also. Highly recommend.

Would have been perfect except for my ignorance. This volume control is rated at 100 W. My receiver's output is 250W. It worked for about 24 hours and then it "blew". I did not understand the significance of the wattage of the unit vs the wattage of my receiver. Amazon was nice enough to allow the return of the unit. I ordered the same product - same company , but the 300W model. It works perfectly! Lesson to be learned. Make sure that the wattage of the volume controller is more than the wattage of your receiver. Would definitely recommend for purchase - just get the right wattage model.

I have installed a lot of volume controls, and I think I may have found my new favorite. The compact size makes it easy to fit in electrical boxes where some volume controls will not fit. I had a job where I needed to fit a volume control into a double-gang box with a mud ring on the front, and the height of the opening was an issue for some other controls that I tried. This unit is probably the most compact one that I have installed yet, as far as height, width, and depth. The easy impedance switch on the front was a pleasant change from jumpers too. This way if you ever add on another pair of speakers to the same amp channels in the future and need to change the impedance settings, you just take off the faceplate and flip the switch instead of having to pull the whole thing out of the wall and change jumpers. I can't say anything bad about this product. The price is fair, I am happy, and I would recommend it to anyone.

There’s a lot to like in this volume control. I love the design, and for the most part I like the implementation. I love the fact that they designed in removable terminal blocks (4-pin ea.) for input and output. This makes wiring this control much easier than a lot of others I’ve used which have fixed terminal connection. The terminals are also nicely silkscreened. The one thing that keeps this product from getting that fifth star, however – is that the retention force of those removable connectors is not that great. I would guess that these are Chinese terminal blocks, as the retentive force of most German terminal blocks are much better. Of course, German brand terminal blocks (ie Phoenix, Wago) cost a lot more as well. So my suggestion would be wait to tuck this unit into its gang box until you know that the total system is operating perfectly - and you can play music while buttoning up. In my case, I had a left speaker that was not working. After tracing the entire system, I finally checked the volume control and sure enough, one of the terminal blocks was loose. That being said, I would absolutely recommend this volume control. Just watch out for that one gotcha, and you’ll end up being very happy.

Works well. Now I can easily turn down my outdoor speakers when I sit on the patio to visit. I made a custom wood box to mount it into. When I built the patio cover there was a short space my speaker wires were accessable. 3/4 conduit held the 4 sets of wires. Everything worked great.

Easy R&R of old volume control which had become staticky. Easy to connect and fit nicely into my existing outlet.

I installed 6 of these. Each one was only controlling one speaker so I only used one channel. One of the speakers didn't work and when I switched the wires on that controller to the other channel it worked. Besides that they seem nice. They fit well in a remodel low voltage ring.

excelente, me fui muy util

My old controls had yellowed and were crackling when turned so I bought these as replacements. Very happy with the decora style and the soft touch when turning the controls. Quality seems excellent. I would buy again.

I read the comments on this item and my only concern at purchase was the possibility the white cover and facing was not truly "white". Not a problem. If it was at some point, the manufacturer has addressed it. The white facing is spot on. The unit had the wiring connections well marked and installation was easy. I bought this unit as a test and I'm now going to buy two more.

Nice in / out layout Good price Fast ship

I bought this in order to be able to control speakers within a pool cabana. With the outside speakers set at appropriate listening level, the speakers inside the cabana were way too loud! This does a great job of allowing me to dial down the volume inside without killing the volume for people around the pool. As other reviewers have indicated, a standard electrical box is not going to be your friend. I bought a standard width box but went with the 3" depth and it made all the difference for me. I punched out the circular, washer looking things (Sorry I don't know what they are called) on both the top and bottom and was able to run the input wires (from the amplifier) in through the bottom holes and the output wires (to the speakers) through the top holes. This left me enough room within the box. I had no issue with 14 gauge speaker wire but I found the secret is to keep the amount of speaker wire exposed to the absolute minimum. The wire slid in nicely and the screw tightened them up firmly. It does a great job but I only gave it 4 stars because of the finickiness of installation and the need for the larger box.
