Review: Works as promised. Easy to install. Appears to be of utmost quality.
Review: I researched many different volume control knobs offered on desertcart and decided to give this one a go! The installation was a breeze! You will need a box extender as these units are quite deep but they’re easy to find on desertcart! When it comes to the knob itself it is very well built, there’s no pausing in the audio when adjusting the level (as others have mentioned) and you won’t be disappointed! Note: The instructions could have been a little clearer when setting the impedance matching toggle... also, I didn’t see this mentioned anywhere but the higher you set the toggle example 1/2x -> 4x -> 8x you’ll notice a drop in the volume output from your speakers however that is to be expected! Overall, I was very happy with this control knob! Like the title says I ended up purchasing another one! The second one was a little temperamental at first but that was due to some wiring that needed to be replaced and due to a more powerful amplifier! I replaced some wires and reduced the volume on the amplifier and now all is awesome with this one too!

## Features

- HIGH POWER: The SKR120 is rated at 150 Watts per channel with minimal bass roll-off, and is often used with multi-channel amplifiers and impedance-matching speaker selectors. Perfect for home theater systems.
- VOLUME CONTROL: The controls allow you to adjust the volume of a pair of speakers independently of other speakers in a house audio system. The last “click” completely disconnects the audio signal from the source.
- FREQUENCY: The SKR120 offers one of the widest frequency responses of any volume control resulting in audiophile sound quality. It delivers an 11-step rotation pop-free control for a wide range of volumes.
- SWITCH: This non-impedance-matching slider volume control features 2 oz. double-sided G10 glass epoxy PCBs, a non-shorting design utilizing a switch to prevent the amplifier from seeing a dead short.
- DESIGN: For dedicated audio zones, the décor plates install easily into a wall and work with almost any system. It accepts 12-14 gauge wiring and fits in a standard gang box with a 2.9” depth.

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.
