What's in the Box: Multi Source / Multi Zone Matrix Routing The Rock Matrix 4 is a 4 zone commercial amplifier that allows you to route any source to a specific zone(s) and also route any microphone input to a specific zone(s). For example, you can play Bluetooth on zones 1 and 2 and route microphone 1 to zones 1 and 2 while playing something in Zone 3 using an RCA input, and playing something else in zone 4 using the ¼” input. You can also route the other mic input to whichever zones you want. Power and Flexibility Each zone has 5 sets of speaker terminals depending on what kind of speakers you have. You can use 70 volt, 100 volt, 16 ohm, 8 ohm, and 4 ohm. No matter what you will get 110 watts RMS per channel. That is 440 watts of total RMS power. For example, you can have (2) 8 ohm speakers on zone 1, (30) 70 volt speakers on zone 2, 16 ohm speakers on zone 3, etc. Lots of input options This model gives you Bluetooth, USB, SD, (2) Sets RCA AUX inputs, (4) XLR Mic inputs, (2) ¼” TS inputs, (4) ¼” TRS LINE outputs (one per zone), Fire input, and a Siren input. There is also a backup DC24V power input in case of a power outage. Flexible controls The controls are really easy to use. You can easily route any source to any zone(s) and select the volume levels for that zone. There is bass and treble EQ controls to customize the sound. There is also a built in 1 watt speaker that allows you to drop in onto any zone and listen to the music playing. Safety first The built-in clipping limiter function protects your speakers and the amp from overheating. For further protection, there is also a cooling system in this amplifier that will keep the components running cool making the amplifier durable and reliable. There is a Fire input and a Siren input. This allows you to easily integrate a fire alarm and play a pre-recorded message that will override any music playing in case of an emergency. There is also a backup DC24V power input that allows you to connect a backup 24V battery that will kick in and power the unit in case of a power outage.

Wonderful simple matrix amplifier combo.
This unit does exactly what it claims. All functions seem to work well without any quirkiness to it. This turned out to be the perfect solution to a 4 way split dividable classroom arrangement.

great feature packed PA system for a restaurant. Has bluetooth, plays MP3s.
Bought this for a small restaurant and used the 70-volt output for ceiling speakers. Had everything I needed for multiple microphones, paging override, zoning for different rooms. Solidly built heavy unit. I liked it so much that I bought another model for another use. I am a pro A-V guy used to installing complex systems, and this one box was great for the small restaurant. ... show more

Four zones at 110watts each.
So far so good. There are four zones in the back with 110 watts each. Took a while to troubleshoot why there was no sound when using Bluetooth. There’s a button in the back that needs to be pressed. Duh! Downside- when you plug in a USB, it starts up the music file right away. I would like the option to press play when I’m ready to. Then if you take out the usb and reinsert it, it starts up in the same place it left off mid-music. Other than that, it works for now. ... show more

NOT GOOD
The unit was no good added (6) of the same brand pendant speakers the sound was horrible. You could not turn the volume up more than a quarter way. I checked all configurations 75 V 120 V. I even changed all the settings on the speakers and still no good. Highly recommend you stay away from this particular unit. The pendant speakers from this company is OK. And will get the job done On another system but this receiver is no good ... show more

VERSATILE AMP
Very versatile power amp. for commercial use. Easy to install. Easy to program. Hard to find a 4 zone amp with 110 w per zone. Unless you are willing to dish out $2,000. There is even a "Rockville" with 6 zone distribution. Great, Great, Great. Also, "Rockville" customer support very efficient.
