R2

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.

Two audio priority inputs and two priority contact inputs are provided. Depending on the configuration, 4 priority signals can be used. The actions that need to happen when a priority signal occurs can be freely programmed. It can switch automatically to the priority audio inputs when an audio signal is applied or the internal routing can be adapted when a signal is available on the contact inputs. Each of the normal inputs can also act as priority inputs.

An internal DSP signal generator is provided which is able to produce sinusoidal signals with an adjustable frequency, white noise signals and pink noise signals.

Two or more zones can be linked so that they use the same source, volume, etc. This linking can be automatically activated using priority contacts so that multiple zones become linked when, for instance, a separating wall is removed.

It is possible to add a filter with freely selectable rollover frequency for up to 4 output channels. The rollover frequency is selectable between 10 Hz and 22 kHz and the filter response is selectable between a high pass filter, a low pass filter and a band pass filter. The filter settings can easily be made in the graphical user interface. When a subwoofer is connected, no more external crossover processor is needed.

The R2 features a full functional web based user interface. This means that the amplifier can be fully operated by means of a web browser, which makes it possible to configure and control it from any device which is connected to the internet, such as a PC, Laptop, PDA or even a smartphone, without requiring additional software.

To access the functions of the R2, just use your standard web browser and surf to the IP adress that is configured in the R2 settings. After logging in with your personal username and password, you have full access to all functions of the R2 amplifier.

The web based user interface is very user friendly, and points out his own. After you have logged in on the website with your personal username and password, a fader overview of all output zones is displayed. The configuration menu gives an overview of all settings which can be made, such as time settings, network settings, priority settings, paging settings and the ability to bridge the outputs of the amplifier.

 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 R2 system using a web browser.
The RS232 connector can be used to control the R2 with external controllers. This allows you to control the system using hardware from other manufacturers like home or industrial automation systems.

 Peripheral Interfaces

There are 10 RJ45 connectors 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 with additional wall line input units.

 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 inputs

There are two priority audio inputs provided, each with a gain control potentiometer. Furthermore, there are also two priority contact inputs provided.

 Input 1-8 / Output 1-8

8 line level in- and outputs are provided. Each audio input channel has a clipping LED which indicates when the input signal is distorted, a gain control potentiometer to control the level of the input signal and RCA input connectors.
Each zone output is standard fitted with an RCA line level output connector for the connection of external amplifiers. 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.
