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.

Works great to control the volume levels in different areas. I am using it in a bar and can control the volume levels in the bar area, kitchen, outside, etc. With 70v no need to worry about impedance. The only thing I noticed is that when I have it at a very low volume is sounds a little staticky, but I'm still happy with it. I used the line out to a powered subwoofer when you want some extra bass. Like one user said, the zone control is not linear, it is stepped, but I do not have any issue with that. If you want a little finer control just adjust the master volume.

Fast shipper!! Came on time for the job

At first, this device looked cheaper than other options, which is why I decided to buy it. I purchased it for my business, expecting it to be a commercial-grade product. During the first week of testing, it worked very well. However, after running it for about 10 hours a day, problems started to appear. The sound cuts in and out, and when the volume is increased, the audio becomes very noisy and distorted. Eventually, the unit stops working. Another serious issue is the screen. As you can see, the device is powered on (the red power light is on), but the screen does not work at all. The unit has power, but the display is completely dead. I originally thought this was a commercial device, but based on my experience, it is not suitable for commercial use. The build quality and performance do not support long operating hours. Important note: my business is not even open yet. I was only testing the equipment in preparation. Once my business opens, it will operate around 15 hours per day, and this device clearly cannot handle that workload. Because of these issues, I do not recommend this product for commercial or business use.

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

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!
