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” TRS 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.

What is 70 volt ?

70 volt systems are the number one choice for any application where you want to install multiple speakers. With 70 volt there are a lot of advantages over 8-ohm systems. One of the main advantages is the simplicity of the wiring as well as how easy it is to match up speakers with the amplifier. For example, with this 440 watt / 70 volt amplifier, you can install speakers that total close to 400 watts. It does not matter if it is 20 speakers that are 20 watts each or 40 speakers that are tapped at 10 watts each. You always want your 70 volt amp to have at least 15 or 20% more power than the combined watts your speakers are tapped at. When we say the word tap, what we are referring to are the selectors that many speakers in 70 volt have on them. For example, some speakers might have selectable options of 1.5w, 3w, 5w, 10w. What this does is limit how many watts the built-in transformer on the speaker will allow the speaker to get from the amplifier. What this allows for is full customization of your sound for your space. In a restaurant, for example, you can tap your dining room speakers at 5 watts, the speakers by the bar area at 10 watts, the ones in the hallway at 3 watts and the speakers in the bathrooms at 1.5 watts. Another great feature with 70 volt is you can mix and match any 70 volt speakers whether they are ceiling speakers, wall mounted speakers, subwoofers, etc.

70 volt systems allow you to run very long lines of speaker wire without signal loss. This makes it ideal when running long speaker leads.

The wiring is simple. You just wire all the positive terminals of the speakers to the positive 70 volt terminals of the amplifier. The negative terminals on the speaker simply get wired to the negative terminals on the amp. You do not have to worry about impedance. The power is constant.
