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!
