Rockville VOL7035 35W 70V Wall Volume Control, 1-Gang, White, Mono Audio, Easy Install, Dust-Protected, for Commercial Audio Systems

funciona tal cual lo indica el proveedor. excelente manera de controlar el volumen de tu amplificador en bocinas.

I had never installed one of these before but it was very easy to use and works great. The connector is a little bit loose but it didn’t cause an issue. Installed with JBL 70v speakers. The markings on the front are very easy to understand and seems to be well-made and durable. Very happy with this.

Great quality 70v volume control! Does what it needs to!Sturdy!

I changed my ratting from 1 to 4 stars. I found my missing control in the mailbox across the street.I installed it and it works good.

Updated Review after 6 months:Inexplicably it just stopped working. Warranty is only 90 days so I am out of luck. We used it (changed the volume) just 2-3 times a day.Original Review: I needed a control for a radio in my steam shower (the switch is *outside* the shower). This worked well for me (so far, I've had it 2 weeks). I needed to use an existing double gang switch plate (rather than the single plate that comes with the unit) & the fit was really tight but it worked. Regarding fit in the electrical box, it was also pretty tight. I had to force it a little since it was hitting the top of my retro blue box.Two downsides: 1) the volume range is a little bit limited but "ok", and 2) the knob as physical stops and therefore doesn't turn smoothly & takes a little effort to turn it unlike a typical volume knob.

If you have a stereo system you will need TWO of these each one only handles one channel.

Placed these in a house for whole house speaker system. They are easy to install and work great!
