Rockville VOL70100 100 Watt 70V Wall Volume Control Zone Controller, White, 11-Step Rotary Dial, Euro-Block Terminal, Dust-Protected Circuit, for Commercial and Home Audio

Straight- forward instructions, well- built. Functions as advertised. My use was to reduce the volume of 70v ceiling speakers in the restrooms of a restaurant. The speakers were not on their own zone, so the volume to the dining room was also the volume to the small quiet bathrooms. Way too loud, with the speakers set to their lowest tap setting of 7.5v. Putting this controller in the run from the amp to the bathrooms was the answer. Running it at the 6th detent, out of 10.My only request would be to make the position indicator dent on the knob easier to see. It's effectively invisible in a dimly-lit environment.

Control works as advertised….HOWEVER…..this does not fit a standard decora style faceplate……..you MUST use supplied faceplate ….just slightly larger opening…..multiple units in decora faceplates do not fit and must be opened up to fit

Works great....I've used two now for commercial applications. One for a new install of a 70v system running 12 speakers in a gym. The second was used inline for an older system where the old installed speakers had all but two of the taps removed... just dropped it inline from the amp to control a locker rooms worth of speakers. Not an ideal solution, but its was all they were willing to pay for and it worked.

God awful quality I ordered 16 of these controllers. The screws to hold the face plate onto the controller is too short. The screw on the top of the controller is long enough to push the Phoenix connector out of the control controller. The output polarity was mislabeled on half of the 16 units that I ordered since I had to get my own screws; They worked in all, but 2 of the controllers that I am now unable to install the faceplate since the wholes had no threads or were threaded poorly.Here I am trying to get multiple screws to fit properly.

👍👍👍👍does the jobJust need an extended box

I needed to replace several broken slider volume controls in my home. I’m not an electronics expert, so it would have been helpful if the product description had noted these controllers only work with MONO speaker setups (single in +/-, single out +/-), not with stereo speakers setups (L/R in +/-, L/R out +/-). Not knowing that I needed 8 connection points instead of 4 would have saved me from misordering this part.Otherwise, these controllers are sturdy and well-built. I wish they had worked for me.

Disappointed with the sound and the connector stickup in the top. Also the decora cover does not fit with other decora covers. Very frustrating.

Great product, fast delivery service
