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

I decided to replace my previous knob volume control (based on impedance matching) after one of the amplifier's channel of my Onkyo Receiver didn't work anymore, and I suspect that the culprit was the inductive coupling. So I decide to replace it by this resistive type, and this one, works perfect. One of the features I like is that has full volume at one end (direct connection, no resistors), meanwhile on the other end, the last step is disconnected (fully isolation of speakers), for great control. It comes with three different colors of covers and knobs to match your taste. It was easy to install, replacement was straightforward. Inputs/outputs on the device are well labeled and the screw connectors make it fast work, connectors also can be detached from the knob control, for easier cable hookup. Product seems of excellent quality. Overall, Recommended.Review made by Handyman

Purchased twice!Very simple to install ! Work perfect!

I'm running Klipsch LaScala speakers along with Heresy speakers. If you know these speakers you realize the volume from the LaScalas will be substantially greater. So I used this volume control to help equalize the sound. Much less expensive than getting another amp! I was concerned about distortion and any sound degradation, but to my surprise there was none.

This volume control matched our switches very nicely in both color and appearance overall. I find that the slider matches the decora style switches better than a knob style control. The fit in the single switch sized box was snug and took some tinkering. But, once in, it looks great and functions very nicely. My only criticism is that the volume adjustment is only moderately smooth. The volume adjustment is not perfectly linear as you adjust up or down. That said, this is not a big issue in my application as I generally control volume via an iOS device.As we will be expanding to a second zone of outdoor speakers, the impedance matching is big selling feature and, while not presently in use, it will be very nice not to have to remove/replace this control when installing the second zone.For our application, it works fine and looks very sleek. If adjusting volume via the control is your primary method, I would add that the slider feels a little cheap in terms of construction and, as noted above, it is not super precise. It'll work and look great though.

Well made. Good quality. Instructions could be better WRT Impedance matching switch.

Works very well.

Works Great.

Easy installation. The wire terminals are removable and are the exact same as my previous volume controls. which made the swap quick by simply unplugging the input and output terminals and plugging them into the new speaker volume control. They also have an adjustable impedance selection, make sure you set this up correctly for your driver amp before install the switch plate. The switch comes with a really good install instruction sheet as well.
