## Description

desertcart.com: OSD Audio 100W in Wall Volume Control Impedance Matching for Home Speakers, Slider White VMS100 : Electronics

Review: The resistive control deliver better sound quality - 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
Review: Perfectly suited. - Works as promised. Easy to install. Appears to be of utmost quality.

### ⭐⭐⭐⭐⭐ Very satisfied. Works perfectly.
*by E***. on September 11, 2025*

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.
