M2

Below we can see an example setup using three matrix units in a medium-sized business.

First of all there is the main offices building with its own matrix, four XMP44 Professional modular audio system. Each zone in the building has its own local DW5066 wall panel for adjusting their zone settings according to their own preference or adding their own music sources to the system. A paging console is positioned near the front desk.

The warehouse has paging consoles setup across the building for easy communication between various parts of the supply and processing chain. Paging calls can be made globally or to specific departments. Local music choice and volume can be edited using DW3020 panels.

Finally the meeting room and its surrounding offices have a more advanced setup. Not only does the room have a powered M2 connected with two wall panels and a microphone, a paging console is also setup to control lighting, projection and window blinds using an ARJ and ARU relay system. Computers throughout the building allow authorised personnel to access the matrix unit's advanced options.

Microphones connected to the M2 using one of its 8 balanced inputs can benefit from the M2’s signal processing to reduce or eliminate feedback. With a flexible system such as the M2, it is important that it can be used to its full potential without feedback. For example, when a microphone is connected for an unannounced speech, you no longer have to worry about unwanted feedback. The M2 makes sure that the speaker only has to focus on his speech.

The M2 allows any number of inputs to be mixed, letting you combine one or multiple microphones with other audio sources in a single zone. The talk over function even dynamically lowers the volume for a certain source when other selected sources are activated. For instance by having the music level lowered when a microphone is in use.

Prerecorded messages and signals can be played directly from the SD card slot on the front of the unit and recalled by either timed actions, triggered actions or control buttons such as those on an AUDAC APM paging console. This can be used for applications such as an automatically triggered doorbell or evacuation.

Playing intelligible audio messages in exceptionally large spaces calls for specialized measures and the M2 is up to the task. In large venues such as arenas or train stations, sound often takes over a second to reach its audience. By using a custom delay, the M2 can assure that each zone plays with a progressive delay, assuring that your message comes across, even to the people in the back. 

 Remote control & RS232

The main remote control input is an RJ45 connector which should be connected to a LAN network. This makes it possible to control the M2 system using a web browser.
The RS232 connector can be used to control the M2 with external controllers. This allows you to control the system using hardware from other manufacturers like home or industrial automation systems.

 Peripheral interfaces

10 RJ45 connectors are provided for expansion with additional wall control panels and in- and output modules. All these connectors contain RS485 control signals so they allow you to control the amplifier from multiple locations. 8 of these connectors are capable of carrying bi-directional digital audio transfer signals for expansion of the input channels and remote output duplication.

 Link in- and outputs

An optional link in- and output allows connection of multiple matrix systems in cascade. This way, audio channels can be transmitted over fiber and installations can be extended over large distances (optional OPT2).

 Priority & contact inputs

Two priority audio inputs are provided, as well as 2+8 input contacts which can be used for triggering a wide variety of actions such as playing voice file messages or recalling mixing presets (scenes, ...).

 Input 1-8 / Output 1-8

The M2 offers 8 balanced stereo inputs that are all software selectable between line and microphone level. A 9th input can be selected from 4 stereo line inputs, useful for switching between multiple sources with a single application such as video or radio.
The M2 also offers a relay output with NO and NC contacts for each of the 8 output zones. These can be used for bypassing analog volume controllers and much more such as activating emergency lights when a message is played, powering up beamers or operating automated curtains.
When the optional power amplifier kit is installed, each zone has an amplified stereo audio output with a power of 2 x 60W at 4Ω.
