Product overview

The R2 is a multi-zone audio distribution system which is a truly polyvalent solution for commercial and residential applications, with the flexibility of a multizone router. It delivers a comprehensive and expandable powerful solution for nearly every situation. With its large number of extension modules and configuration modes, it provides a solution for an uncountable amount of installations – large or small, simple or complex.

In general, it is an 8 x 8 digital audio matrix system, which is based on a powerful DSP processor. It is fully digitally controllable, and the built-in digital matrix makes it possible to patch any of the input signals to any of the output signals.

Note: The AUDAC R2DIS interactive 7" touch-screen display kit shown on some promotional images of the R2 is an optional expansion kit not included in the standard R2. R2DIS units are currently not available.

Detailed product information



Remote control: The 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.

RS232: The RS232 connector can be used to control the R2 with external controllers. This allows the control of the system with hardware of other manufacturers.

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, this allows the control of the amplifier from 10 different locations. 8 of these connectors also contain digital audio signals for expansion of the in- and output channels with additional wall line in- and output units.

Input 1-8 / Output zone 1 - 8 There are standard 8 line level in- and outputs provided. Each audio input channel is fitted with a clipping LED to indicate 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 40 Watt.

    

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

Digital audio in- and outputs: There are digital audio in- and outputs provided which are both optical and coaxial provided.

Link in- and output: There is an optical link in- and output provided which is meant for connecting more amplifiers in cascade by means of a fiber interconnection. (optional)

The functions

Timer scheduling

An internal real-time-clock is provided which holds the actual time and date. This gives the possibility to create specific time schedules. The actions that can be programmed is to change the routing of a signal or adjust the volume of a zone, play a voice message and turn the amplifier on and off.

Single actions at a certain date and time or actions which repeat regularly (every day or week) can be programmed. A total of up to 256 timer presets can be made.

For example, this can be useful when installed in a shop, the system turns-on at morning, turns-off at night and remains off at the weekends and plays pre-recorded advertising messages hourly.

Internal DSP signal generator

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. These signals can be used as test signals, but in combination with the AUDAC ASL30 sound level meter the noise signals can be used to mask background noise in environments where silence is required. When the level of the background noise increases, the noise level will be adjusted inconspicuous. In this way, despite the increasing background noise, a quiet environment is maintained. This application is often used in libraries and reading rooms where a quiet environment is required.

Freely programmable DSP filters

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

Priority inputs

There are two audio priority inputs and two priority contact inputs provided. Depending of 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 a audio signal is applied, or the internal routing can be adapted when a signal is available on the contact inputs.

Web based user interface

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.
