OSD Audio 100W in Wall Volume Control Impedance Matching for Home Speakers, Slider White VMS100

Works great! I installed this for my outdoor speakers. Installation was easy and instructions were easy to follow.

Is as stated good quality. Quick delivery

Works perfectly

I installed 4 volume controls this weekend. They replaced NXG-70 rotary knob controls. Contrary to what some users have reported, these fit into a standard plastic gang box without any issue (They take up the same amount of room as the NXG models), however if you have a lot of extra speaker wire in the gang box it can be a tight fit. My advice would be to trim up the wires to the minimum required anyway. For me, installation was a breeze and looks MUCH nicer than the rotary versions. The slider does have a slight cheap feeling from the off position, but tightens up quickly. Not enough to concern me. Great Purchase for the money!!! If you're a business installing these, I would go with the Dayton Models, they look and feel a bit nicer. They are double the price though.

Easy to install

The screw connectors are small, but provide solid contact and are well-marked to know which wires go with which connector. The slide bar is smooth and provides a good range of volume. No static sounds when adjusting volume, which is nice compared with some knob controls I've tried in the past. Comes with different color faceplates and even different color screws. Good product for a fair price.

I would say 14ga is pushing it for max wire size. It says 12ga, but man is it tight in the 2 gang box with this and the push button source switcher. Had to make sure all excess wire was pushed back into the wall. I prefer the OSD Slider versus the OSD knob for volume control. I bought an OSD push button source selector, but I have decided to change to the OEM Systems because the button is larger and there is a graphic on the front showing A vs B source. I have a small 50x2 amplifier to power a couple Polk Audio in wall speakers. This switch supports the 100w total I need for this solution. If you need more wattage to larger speakers, you need to move up to the 300w model. Its much heavier, and you will have even less space in your gang box. Consider cutting off the back of your deep gang box to make the installation easier. It was too late for me. Also you can pull the black and red connectors out and make your wire connections first, then plug it back in. Thats much easier.

These are nice little units. The screw-secure terminal blocks are nice. They do fit in a standard single-gang box, but they are TIGHT in the boxes, so if you have a lot of heavy-gauge wire (14 and up), you might want to use a different solution (dual gang or low-volt type, etc). Because the walls were cellulous-filled, we had to use electrical boxes, and while they worked, it was - as noted - TIGHT. That being said, they work nicely so far. Two months in and no issues. Different (included) faceplate color and slider colors are a nice touch. Units seems nicely made of quality components, and will hopefully last a long time.

Works well and looks good too! Will be buying another for my dining room. It easy to install and the wire connections at the back pops off for easy install, then clips back on. A deep electrical box would be beneficial as the item is quite deep and would make arranging with wires much easier.

Fastest shipment I've seen. Seems like good, solid, heavy unit. Seems to work very well. But do urself a favour, install in a very deep box, saves stress on the connections and headache.

These work great and a good value compared to similar options. Definitely recommend.

The unit itself is solid. The internal electrical is solid, but you do need a fairly massive gang-box to house it. The detachable wire connectors are very helpful, but could stand to be a little larger or spread out a bit better. The volume control is better than expected, although if there is any problems with grounding, there is a predilection for static/squelch. The extra face plates are a nice bonus. You will likely need a very fine tipped screwdriver, electrical tape, and fine tipped connectors/soldering skills to complete the job to a professional and foolproof level. Other than that.... they worked as well as to be expected. And, it's such a great thing to be able to control volume levels to different areas.

Great product. Previous switch would let sound through even at the lowest level and this new switch turns the volume off completely. Good product!
