RockvilleVOL7035 35w 70v Black Wall Volume Control Zone Controller Box 1-Gang

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.

Excellent

The easiest install of a product that I have done in some time. It seems like there is always something extra that you didn't know about to complete the installation correctly. This product was straight forward and worked well.

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.

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.
