Rockville RCS350-6 350W 6 Zone 70V Commercial Amplifier, Bluetooth, USB, Optical, Rack Mount, for Restaurants and Offices

This thing is awesome - definitely worth the price for everything it can do. I'm using it to run multi zone ceiling speakers in my home but also use it for karaoke; 100% functioning off Bluetooth with my iPad/iPhone. The unit allows us to control volume for each zone as intended and it has a built-in equalizer. There is no on/off switch for each zone but by turning the volume all the way down you are essentially turning off the unwanted zone. We are using 6x 250W, 8in celling speakers. The best part is that there are three microphone inputs which allow you to karaoke over the music you are playing. LOVE this for house parties. The microphone input on the front is the primary, meaning it will always work over the two on the back. We want two people have their own mic's so we don't use the front input. The only fault is that the green plastic piece you insert the speaker wire is pretty flimsy (see pic). You need to make sure you don't push down on it while screwing in your wire or you will break it off.

It is an awesome improvement for our foyer! We were getting a buzz in the the sound and could not get any volume before but now it is great!

Installed this in a local VFW Post as a replacement for their 20+ year old mixer/amplifier. It sounds wonderful even with the crappy speakers in the ceiling, It's easy to use. One thing that could be improved upon, the knobs could be color coded or stamped for easy viewing. Bluetooth works great.

Easy enough to set up. Most of the controls are self-explanatory. I did find it tricky to set up the FM reception without using the remote control, which otherwise (given my setup) will be rarely used.The biggest issue I have is that I can't get the front mic (mic #1) to work adequately. If I plug my mic into #2 or #3 (on the rear panel) it seems to work fine. When plugged in to #1 your can hear the attenuation of the volume change (per the rear muting control) but you don't hear the mic. Take the same mic and plug it in to either of the rear plugs and it works fine. I called tech support and walked through this and they decided it was a bad unit and took it back. In the meantime, I ordered another new unit and it does the same thing. Since I was planning to mount a wall jack for #2 and #3 anyway I just kept it, as overall I think it works ok.Some minor things suggest the build quality may not be up to scratch, such as the fact that you almost have to strip out the screws that hold in the rack mount ears when you install them. I just should be that hard.Customer support did seem to cover the appropriate settings when I called them--just think it's weird that 2 of these could have the same problem.

Fast shipper!!Came on time for the job

Another fast shipment and having multiple zones controlled independently worked perfect for our shop

After playing for a while, it produces a strange noise. The sound system is not reliable.

This is amazing! We have hard wired speakers with about 6 zones and was told it would cost us over $1k between the amp and sonos connect to get the right sound. So not the case! We took the chance on this—hooked it up yesterday and the sound in each room is just what we wanted. No regrets as of now. If something changes, we will update!
