Introduction

Multi-Zone Audio Matrix System

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.

It is standard equipped with 8 analog line inputs and 8 analog line outputs, but the flexible
structure of the device makes it easy to extend this number to an appropriate solution for
each specific situation.

If desired, it is easy to cascade multiple R2’s with the fiber interconnection modules. This
makes it possible to transfer up to 8 stereo channels and to extend to an nearly unlimited
number of zones.

But it is much more than that, due to the extremely powerful DSP processor, it provides
greater flexibility, higher reliability and lower latency than any other amplifier of its kind.
Moreover, it ’s capable of doing complex calculations on the digital audio signals, which makes
it possible to integrate digital filters into the system and generate complex audio signals.

Every R2 is standard equipped with an integrated Ethernet control interface which makes it
possible to configure and control the R2 from any PC, laptop or PDA which is connected to
the internet. Just use your browser, go to the appropriate website and you have complete
control of the R2.

An optional touchscreen can be installed in the front of the amplifier and there are optional
wall control panels whereby the desired music source and volume can be selected for a
specific zone.

A RS232 interface is provided for configuration and control with peripherals from other
manufacturers which make use of an RS232 connection, like AMX, Crestron,… the control
commands are freely available which makes it easy to develop specific applications that
work in combination with the R2.

8 line level in- and outputs are provided in its standard
configuration. Each line input is fitted with stereo RCA input
connectors and a clipping LED which illuminates when the
signal reaches the clipping level. By means of the gain control
potentiometers, the level of the input signals can be controlled.

Each zone output is fitted with RCA stereo connectors for the
connection of external amplifiers. When the optional power
amplifier kit is installed (POW), each output zone has an amplified
stereo with a power of 2 x 60 Watt @ 4 Ohm or 2 x 30 Watt @
8 Ohm. The amplified zone outputs can be bridged by Hardware,
Using the L+ and the R- to obtain a power of 120 Watt @ 8 Ohm
for each output zone.

Audio in- and outputs

Priority & Fiber

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. There can be automatically switched 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.

The link in- and outputs are optical fiber connectors which can be
used for cascading multiple R2’s. For this feature, the optional fiber
interconnection module (OPT2) has to be installed.

Rear

14

Peripheral interfaces

10 RJ45 (RED) connectors for expansion with additional wall panels and
in- and output modules are provided. All these connectors carry RS485 data
signals. This allows the control of the Matrix from 10 different locations.

8 of these connectors are able to carry digital audio signals (RS485(1) to
RS485(8)) for Audac paging microphones (APM) and all-in-one wall panel
DW5066.

Control ports:

The RJ45 remote control input should be connected to a LAN network.
This makes it possible to control the R2 system over Ethernet, by means
of a web-browser or mart devcie when combined with a WIFI router and
Audac touch.

The RS232 connection can be used to control the R2 with external
control equipment supporting RS232. This allows to couple the R2 with
your home automation system, and control it through hardware of other
manufacturers, like AMX, Crestron, ….

Power inlet:
The main power supply (110~240V AC / 50~60 Hz) has to be applied to
this AC power inlet. The connection is made by an IEC power connector
and is fitted with a fuse. When replacing the fuse, make sure that the
value of the replacement fuse matches the value of the original fuse.
(T2AL/250V)

Emergency power inlet (24 Volt):

A 24 Volts emergency power supply can be connected to this 2-pin
Terminal block connector for keeping the R2 running on emergency power
when the mains power is shut down. When the R2 is running on 24 Volt
emergency power, the function of the power switch on the front panel is
bypassed and can’t switch the R2 off.

NOTE: When installing the optional Power Amplifier kit, the fuse needs to be changed
accordingly, and should be replaced by a T4AL/250V fuse (included with POW2).

R2 Quick start guide

This chapter guides you through the setup process of a basic project with one R2 audio matrix
and 8 standard DW3020/4020 wall panels.

Overview of the R2 setup

Connecting the R2

1) Connecting audio sources

Connect all your audio sources (CD-players, tuners, ... ) to the line inputs (RCA
connectors) on the rear panel of the R2. Adjust all input gains to the appropriate level so
no clipping occurs.

2) Connecting amplifiers and/or speakers combined with a WIFI router and Audac
touch

Connect amplifiers (100V or low impedance) to the line outputs (RCA connectors) on
the rear panel of the R2. When the optional power amplifier kit (POW2) is installed, low
impedance loudspeakers can be connected to the loudspeaker outputs (Euro-Terminal
block connectors) on the rear side of the R2.

3) Connecting wall panels

Connect the DW3020/4020 wall panels to the Peripheral Interface (PI) inputs (RS485
connectors) on rear panel of the R2. Multiple DW3020/4020 wall panels can be connected
to one single PI input by using bus cabling (connecting all the wall panels in parallel), or
each wall panel can be connected to an PI input by a separate cable. It doesn’t matter
which PI port is used for which zone.

when connecting the DW5066 wall panels only one can be connected to any one RS485
port at any one time, these limits the total connectable DW5066 devices to 8.

It is recommended that the DW5066 is connected to the a port number that matches the
output it is controlling, this will make configuring the R2 and input naming easier during
the installation.

4) Connecting a computer
A computer can be connected to the R2 through true ethernet. If the computer is directly
connected to the R2, a crossed network cable is necessary. If the R2 is connected to
a local LAN network (connected to a router / switch / hub) a straight network cable is
necessary. Ask your IT administrator for help.
To get access to the user interface, enter the following address in your internet browser
address bar: “http://192.168.0.191” (This is the factory default IP address of the R2, can
be changed in the user interface). The default administrator password (gives you access
to all functions) is “R2” and the default user password (gives you only access to the basic
functions) is “user”. If you want to make any changes to the settings, you should log-in
with the administrator password.

Configuring the R2

1) Changing the IP address

You can skip this step when the default IP address “192.168.0.191” is not used by another
device in your network, and is OK for you. If you like to change the IP address, go to
the “Setup” menu (click the icon in the upper right corner of the main screen) and click
“Network Settings”. Now you can change the IP address, and click “OK” to apply the
changes and save. Afterwards, your browser will be automatically redirected to the new IP
address of the R2, and the default IP address is not longer valid.

2) Changing the password
You can skip this step if the default password “R2” for administrator and “user” for users
is OK for you, buy we always recommend to change these passwords, especially when
your R2 is connected to a public network where external users have access to. If you like
to change the password, go to the “Setup” menu and click “Password settings”. Here you
can change the passwords. First, the old password needs to be entered, and subsequently
the new password needs to be entered twice (Max 10 characters). Press the “OK” button
to save the new password. Now, you always need to log-in with the new passwords and
the default passwords are not longer valid.

3) Configuring wall panels and sources

Go to the “Setup” menu and click “System configuration”. Now you have the possibility
to choose between “Paging”, “DW5066” and “DW3020/4020”. To configure the settings
for the DW3020/4020 wall panels, click the corresponding button. By the dropdown list
on the left side, you can choose for which zone you want to configure a wall panel. After
the desired zone is selected, you can assign one of the connected wall panels with that
particular zone by clicking “Set Address”. The displays on all wall panels will start blinking
with the selected zone number. Push the “Program +” button on the wall panel if you
want to assign that particular wall panel with the selected zone. After the “Program +”
button is pressed, the wall panel will be linked with the selected zone, and the display will
stop blinking.

The R2 contains many different inputs which can be selected to link with a zone. 8
of those inputs are accessible through the “Quick menu” (dropdown list on the main
page). The same inputs which are available in the “Quick menu” can be selected on the
DW3020/4020 wall panels. The other inputs are accessible through the settings menu if
you are logged-in as administrator.
You can choose the inputs which are selectable in the “Quick menu” and with the
DW3020/4020 wall panels through the “Input selection” menu in the “Zone Settings”

Settings >> Priority settings

The priority settings menu makes it possible to configure the priority channels. On top of this
window, all priority inputs are displayed ranging from Priority 1 to Priority 4. The input selected
for Priority 1 has the highest level of priority, the input selected for priority 4 has the lowest.
Note: On all Audac devices, priority settings always have priority over paging.

Priority input selection
You can select the desired priority channel by clicking on the corresponding button on
top of the window, and switching them on and off can be done by clicking the “Enabled”
button. When the priority is enabled, this button will turn green.

On the left side of this window, there are a “Trigger” and a “Input” dropdown list displayed.
In the “Trigger” dropdown list are all the inputs shown on which the priority can be triggered.
This ranges from the direct line inputs to the fiber and wall panel inputs as well as the internal
test signals. In addition to these input signals four priority inputs are displayed (two priority
signal inputs and two priority contact inputs). Here you can select on which input signal the
priority needs to be triggered. When an priority audio input is selected, there will be switched
to priority when an audio signal is present on these inputs. When a contact input is selected,
there will be switched to priority when a contact is made between those two pins.

In the “Input” dropdown list below, there can be selected which input signal has to be patched
when a priority situation occurs. In this list, the two direct priority audio inputs, the regular
direct RCA inputs, the Wall panel inputs, the Fiber inputs, but also the DSP and other input
signals are displayed.

On the right side of the window is a list of all output channels displayed. In this list can be
selected to which output zones the priority channel needs to be patched. This can be done
by simply clicking the button next to the channel. When the priority signal for this zone is
enabled, the button will turn green.

31

Next to every output zone is a dropdown list displayed whereby the volume can be selected
in steps of -1dB.

The switching to and from a priority signal is done according to the HARDIN - FADEOUT
principle. This means when a priority situation occurs (signal present on the priority audio
inputs or connection between priority input contacts) , immediately will be switched to the
selected priority action. When the priority situation is over (no more signal present on the
priority audio inputs or no more connection between the priority input contacts), the status
of the R2 will return to the previous status by fading the sound in.

Click the “OK” button to confirm the priority settings.

Peripheral interfaces

The R2 offers the possibility to connect many additional input and control units in addition
to the standard direct line inputs.
To connect those additional units, peripheral interface ports are provided on the rear side
of the R2. In the further explanations of this user manual, we will refer to the peripheral
interface ports (RS485) with the letters “PI”, followed by a number ranging from 1 to 10,
each representing one PI port on the rear side of the R2. As this already suggests, there
are 10 PI ports available on the rear side of the R2, each of them performed with an RJ45
connector. 8 of these PI ports are capable of transporting bidirectional audio and data
(ports PI 1-8), while the remaining two ports are only capable of transporting data (ports
PI 9-10).

Devices possible to connect to the PI ports:

DW3020/4020 Basic wall panel with routing and volume control

Multiple DW3020/4020 wall panels can be connected in a bus structure. This wall panel
is only using digital data transfer and no audio transfer, so it can be connected to all
peripheral interface ports from PI1 to PI10. The assignment of the wall panel with a zone
should be done in the user interface.

DW5066 Advanced wall panel with graphic display stereo line input and
microphone input

This wall panel can control multiple zones and has a direct digital audio link to the R2.
Only one DW5066 wall panel can be connected on one PI port, and only PI1 to PI8 can be
used for connecting DW5066 wall panels.

APM Paging system
The APM paging system can be used to page to different paging zones of the R2. Paging
to zones on other R2’s is also possible when multiple R2’s are linked with each-other
through the (optional) fiber interface OPT2.
APM paging consoles can only be connected to PI ports PI1 to PI8. Multiple APM paging
consoles can be connected to one PI port, using a bus structure with ARJ03P junction
boxes. When multiple APM paging consoles are connected to one PI port, only one APM
console can announce messages at a time, so the paging is priority based. Paging with
different APM consoles in different zones is possible when the APM’s are connected to
separate PI inputs.

38

Connection possibilities

Working connections:

- Multiple DW3020/4020’s on one PI input (PI1 to PI10)

- One DW5066 and multiple DW3020/4020’s to one PI input (PI1 to PI8)

- One APM and multiple DW3020/4020’s to one PI input (PI1 to PI8)

- Multiple APM’s (priority) and multiple DW3020/4020’s to one PI input (PI1 to PI8)

Connections that don’t work:

- DW5066 and APM to one PI input

- DW5066 to PI9 or PI10

- APM to PI9 or PI10

- Multiple DW5066 to one PI input

Important

Always make sure the R2 is powered off when connecting or
disconnecting devices to the PI ports.
When an audio signal is transmitted to the peripheral inputs from an
external input device (e.g. DW5066 wall panel or APM paging console)
the used cabling should always be UTP/FTP CAT6 cable or better.

Wall mounted control panels

The R2 installation can be expanded with additional wall control panels. There are two kinds
of wall panels available, one standard wall panel (DW3020/4020) which allows to adjust the
routing and volume for a particular output zone, and one All-In-One wall panel (DW5066),
which provides the possibility to connect an additional Line of Microphone signal source in
a specific zone.

DW3020/4020 (Left) & DW5066 (Right) Wall panels

The wall panels should be connected with the peripheral ports on the rear side of the
R2, by means of Twisted pair UTP/FTP CAT5 (or better) cabling for DW3020/4020 and
UTP/FTP CAT6 (or better) cabling for DW5066. It is possible to connect multiple standard
(DW3020/4020) wall panels on one single peripheral port (Up to 32 wall panels according
to RS485 specification). Only one All-In-One wall panel with audio inputs (DW5066) can
be connected to each peripheral port.

DW3020/4020 Basic wall panel

Functions

The DW3020/4020 is the basic wall panel which allows to control the routing and the
volume of the R2. A selection out of up to 8 input signals can be made by means of the
DW3020/4020 wall panel. The inputs which are selectable by means of the wall panel can
be configured in the user interface under ‘Zone settings’ and ‘Input Selection’. How this
works is extensively described in an earlier chapter of this user manual. First read the PI
connection principles in the beginning of this chapter before making any connections.

Change routing
In normal conditions, the DW3020 display will show the routing by indicating the number
of the selected input signal which is routed to the related zone. If the “Prog +” button is
pressed, the next pre-defined input will be selected, if the “Prog -” button is pressed,
the previous pre-defined input will be selected.

Change volume

The volume in the corresponding output zone can be changed by pressing the “Vol +”
and “Vol -” buttons. Logically, the volume will be increased after pressing the “Vol +”
button will be decreased after pressing the “Vol -” button. When the volume is changed,
the display will show the volume level for two seconds, and after those two seconds, the
routing will be displayed again.

Configuration
Before the DW3020/4020 wall panels can be used, the wall panels needs to be assigned
to one particular zone. Perform the procedure described below to make sure this is done
correctly.

Go to the “Setup” menu and click “System configuration”. Now you have the possibility
to choose between “Paging”, “DW5066” and “DW3020/4020”. To configure the settings
for the DW3020/4020 wall panels, click the corresponding button. Now a window with a
dropdown list is shown, displaying all the available zone names. Select the zone whereto
a wall panel should be assigned, and click the ‘Set Address’ button. All connected wall
panels will start blinking, and after pressing the upper button on the desired wall panel,
it will be linked to the selected output zone. If multiple wall panels should be assigned to
one zone, simply repeat this action.

Maximum cable length
The maximum cable length depends of the number of connected wall panel. When only
one wall panel is connected, a maximum cable length of 600 meters can be reached. The
table below gives an overview of the maximum cable length, depending of the connected
wall panels.

DW5066 All-in-one wall panel

Functions

The DW5066 is the advanced All-in-one wall panel for the R2. This wall panel has a
graphic display and can control the routing, volume, bass, treble and mute for multiple
zones (up to 8) on one R2. Besides those control functions, it also provides the possibility
to connect a microphone and a stereo line input source. The DW5066 wall panel should
be connected to the R2 by means of a UTP/FTP Cat6 (or better) cable. First read the PI
connection principles in the beginning of this chapter before making any connections.

The following functions of multiple zones of the R2 can be controlled:

- Volume within a range of 0dB to -70 dB

- All inputs can be selected

- Mute can be activated

- Bass within a range from -9dB to +9dB

- Treble within a range from -9dB to +9dB

Configuration
Before the DW5066 can operate, the configurations should be made. First of all, an
address need to be assigned and the available inputs need to be defined.

Follow these steps to configure:

1) Go to the “Setup” menu and click “System configuration”. Now you have the possibility
to choose between “Paging”, “DW5066” and “DW3020/4020”. To configure the settings
for the DW5066 wall panels, click the corresponding button. Now a window is displayed
which provides all the configuration possibilities for the DW5066. On the left side, a
dropdown list is displayed whereby the address for the DW5066 can be selected. The
address can be selected between “W001” and “W008”. Logically, you start with address
“W001” for the first wall panel, and increases for every additional wall panel. After the
desired address is selected, click the “Set address” button. After this button is pressed,
the DW5066 will start blinking. To confirm the selected address with the wall panel,
click the big rotary button on the front of the wall panel. When this button is pressed, the
address will be assigned to the selected wall panel.

NOTE

It is recommended that when assigning the DW5066 an address the number matches
the socket location on the back side of the R2. In this was W001 will also represent
RS485(1)

2) The zones which you want to control with the selected wall panel can be selected by
means of the “Controlled zones” dropdown list. When selecting a zone in this dropdown
list, the zone name will appear in the listbox below. The zones can be removed again from
this listbox by selecting them, and clicking the “Remove Zone” button.

3) The inputs which are selectable with the selected wall panel can be selected by means
of the “Selectable inputs” dropdown list. All inputs which available on the R2 can be
selected in this dropdown list, such as the direct line inputs, the peripheral inputs, the
fiber inputs, the priority inputs and the integrated DSP signals. When selecting an input
signal in this list, the signal name will appear in listbox below. The input signals can

41

be removed again from this listbox by selecting them, and clicking the “Remove Input”
button. A maximum of 24 signal inputs can be selected. The inputs which are selected in
this listbox, are available for all zones which can be controlled by this DW5066 wall panel.
Those inputs are not linked with the quick menu like the inputs on the DW3020/4020 are.

4) Certain actions such as Volume change, Input change, Mute change, Tone control
change and settings change can be blocked by checking the checkboxes.

5) The microphone input has the possibility to provide +15V phantom power for powering
condenser microphones. The phantom power can be switched ON and OFF by clicking
the “Enable Mic Phantom” checkbox. This setting can also be changed in the DW5066
settings menu. (If “Block settings menu” is not checked)

Paging

1 Zone paging example

The most basic example of an R2 paging system is an R2 audio matrix, in combination
with an APM101MK2 paging console. This setup makes it possible to announce messages
in 1 or more pre-defined zones, and with a pre-defined volume for every zone.

8 Zone paging example
A second paging example of an R2 paging system is an R2 audio matrix, in combination
with an APM108MK2 paging console. The difference between the previous example (with
APM101MK2) are the amount of paging zones. The APM108MK2 console contains 8 zone
selection buttons, which makes it possible to page separately to all zones, or to page to
multiple zones at a time.

Priority

Paging is always priority based. When multiple APM consoles are connected to one R2,
and multiple APM’s give a command to announce a message at the same time, it depends
of the priority settings which message will be announced. The priority level is related to
the address of the APM table by default but this is configurable.
For voice files and messages which are stored inside the APM memory, the priority works
differently. A priority number can be assigned to each stored message, making it possible
to give emergency messages a higher priority.

Connection possibilities

Two different connection methods are possible for connecting multiple APM’s to one R2.

1) Bus structure
Multiple APM’s can be connected in a bus structure, on the same PI Input. Only one APM
paging console is able to page at a time, so this is always priority base.

44

2) Separate PI input
Multiple APM’s can be connected to the R2, each of them using a separate PI Input. If the
selected paging zones are different, paging to different zones can be done at the same
time. If multiple APM’s are trying to page to the same zone at the same time, then paging
is priority based, and only the message coming from the APM with the highest priority
(lowest address) will be announced.

Paging over fiber

When multiple R2’s are cascaded with each other through the fiber interconnection
interface, paging messages can be transferred over the fiber conductor, making paging
possible in multiple zones of multiple R2’s. When this option is enabled, audio channel
one (FB1) is dedicated for paging purposes, whereby this channel can’t be used for other
purposes.
Paging over fiber is always priority based, and only one APM can page to multiple R2’s at
the same time.

Limits

When multiple APM’s are connected on one PI port using a bus structure, a maximum of 6
APM’s can be connected to one PI port, with a maximum cable distance of 300 meter for
the total APM bus.

Connection limits summary

- Maximum 9 APM’s on one PI port

- Maximum 72 APM on one R2

- Maximum 300m when Cat 6 cable is used

- Always use ARJ03P junction boxes with external power supply when multiple APM’s
are connected using Bus structure.

- Use CP43ARP when distance exceed 300m

Configuration
To make the entire paging system work acording to the needs of your project, a
configuration procedure should must be followed.

Paging volume

The paging volume can be different for every zone, and should be configured individual
for each specific zone. To configure the paging volume, go to the “Setup” menu, and click
the “Paging volume” button. By means of dropdown boxes, the paging volume for every
specific zone can be set. Any changes must be saved.

APM configuration

The paging settings are stored inside the APM’s internal memory. For configuration, the
APM should be connected to the R2, and the configuration should be done through the
web based user interface of the R2 or via the Audac system manager. You can find the
paging configuration settings in the “Setup” menu, under “System configuration”, and
“Paging”. On the left side of the window are the settings for configuration of ARU’s shown,
while on the right side the settings for configuration of the APM’s are shown. Follow the
procedure below to make your paging system work successful.

1) Select the address which you want to assign to your paging console.
Select the address by the dropdown box, and click the “Set Address” button. Now, the
“PTT” (push to talk) button on all connected APM’s will start blinking. After pushing the
“PTT” (Push to talk) button the address will be assigned to the selected APM. For more
information regarding the APM address, see “Priority in chapter 6”.
When multiple APM’s are connected to one R2, it’s better to assign an unique address to
every APM, before continuing with the configuration procedure.

2) Select the APM and the amount of layers (only applicable for or APM116MKII)for your
configuration.
Press “New Configuration”. After pressing this button, you will be redirected to a new
window where you can select which APM you want to configure. Two dropdown boxes
are shown, by means of the upper one the R2 whereto the APM is connected should be
selected. When only one R2 is used, only “R001” will be shown. By the lower dropdown

46

list, the peripheral port on which the APM is connected can be selected, ranging from
RS485(1) to RS485(8). When APM108MK2 or APM116MK2 are connected, the number
of layers for your APM configuration can be determined by means of the dropdown list on
the right side of this window.

When the desired APM (and the amount of layers) is selected, click the save button, and
you can proceed to the next window.

3) Configure the APM buttons
This window gives an overview of your APM keypad. The number of buttons displayed in
this window depends of the type of APM which is connected to your system. On the left
side, a dropdown list allows you to browse between the layers (when available).
Just click the button to which you want to assign a function.

After this button is clicked, a windows comes up allowing you to select the function which
should be performed after pressing this button. The available functions shown in the
dropdown list on the left side are “Zone Select”, “Play Message”, Toggle Relay and Pulse
Relay.

47

Zone Select:
This function should be selected when the button is meant for paging purposes. The
zones where the message should be audible after pressing the button are displayed in
the “Selected Zones” listbox. Zones can be added to this listbox by selecting them in the
two dropdown lists on the right side followed by clicking the “Add”’ button. Zones can be
removed from this listbox by selecting them, and clicking the “Remove” button. Up to 40
zones, from 5 cascaded R2’s can be programmed under one button.

Play message:
By means of this function, messages stored in the APM memory, such as emergency
or commercial announcements can be announced. The stored messages are shown in
the “Message” dropdown list from where the desired message can be selected. The
priority of the message is based on the priority number which can be set in the “Priority”
dropdown list, and is not related with the APM priorty. This way, high-priority emergency
messages can be played with a low-priority APM.
The lower the priority number is, the higher the priority of the related message.

Chapter 7

Cascading the R2

This chapter explains the fiber interconnection possibilities between several R2 matrixes,
and guides you through a setup process of a project with 5 R2’s cascaded with each other
by means of the fiber interconnection interface.

Principle

The (optional) fiber interconnection interface makes it possible to transfer 8 stereo audio
signals and one data channel over one single fiber optic conductor. The data channel
is transmitted automatically and can’t be configured by the user. The 8 stereo audio
channels which should be transfered over the fiber conductor can be configured by the
user.

The fiber interconnection interface of the R2 works like a ring network. This means that
every R2 has one fiber input and one fiber output. This ring must be closed in all cases and
this can be done by connecting the output of the first R2 with the input of the second R2.
The output of the second R2 should be connected with the input of the third R2, and so on.
At the end, the output of the last R2 has to be connected with the input of the first R2. This
way, a ring is closed and the network is completed.

To control all the functions of all the R2’s in one network, only one connection with the
ethernet network of one R2 in the ring network is required. When multiple R2’s are connected
in a ring network, first a selection box will be displayed whereby can be selected which R2
you want to control.

Each R2 can transfer one or multiple of his input channels through the fiber ring network.
This can be any input of the R2 (Line input, PI audio input, Digital input, ... ). The selection
of which input signal should be transfered over the fiber ring network can be selected in the
“Setup” menu, after selecting the “Fiber settings” window.

Every signal which is received through the fiber ring network can be used as a regular input
just as all the other inputs, can be selected through the wall panels, and can be patched to
any of the output zones.

When an R2 transfers an audio signal over the fiber ring network, there is the possibility to
transfer the signal to all R2’s in the same ring network, or to transfer the signal only to the
next R2 in the ring network. If the signal is only needed for the next R2 in the ring network,
the second R2 can use this channel to transfer another signal to the third R2, and so on...

Fiber audio flow

The diagram shown below shows an audio flow of an example project with 5 R2’s cascaded
through the fiber interconnection interface where every R2 has an address going from “R001”
to “R005”. Next to every R2 are shown which signals are received and transmitted over the
fiber, while next to the connection line is shown which signals the fiber is carrying at this point.

Diagram explanation

Every R2 is indicated with a different colour, and next to every R2 is a table shown with 8 incoming
fiber audio channels and 8 outgoing fiber audio channels. Between two devices, a connection
line is shown representing the fiber conductor, and next to this connection line is always a table
shown which indicates the audio channels the fiber conductor is carrying at this point. The
audio channels between the output from the previous device and the input of the next device
are always unchanged. This is clearly displayed by means of the text colour inside the tables.
When APM paging consoles are connected and paging over fiber enabled, then channel “Fb
1” is dedicated for paging use and can’t be used to exchange other audio channels. For this
reason, channel “Fb 1” is always marked with “Paging”.

An overview of the audio signals transmitted over the fiber interface:

- Fiber channel 1 (Fb 1): This channel is dedicated for paging purposes

- Fiber channel 2 (Fb 2): The Red R2 (R005) transmits an audio signal over fiber

channel “Fb 2”. This signal reaches all devices and can
be used by all devices.

- Fiber channel 3 (Fb 3): Same as channel “Fb 2”, the Red R2 (R005) transmits an
audio signal over fiber channel “Fb 3”. This signal
reaches all devices and can be used by all devices.

- Fiber channel 4 (Fb 4): The Yellow R2 (R001) transmits an audio signal over fiber
channel “Fb 4”. This signal reaches all devices and can
be used by all devices.

- Fiber channel 5 (Fb 5): The Blue R2 (R003) transmits an audio signal over fiber
channel “Fb 5”. This signal reaches all devices and can
be used by all devices.

- Fiber channel 6 (Fb 6): Channel 6 is used by two R2’s. The Orange R2 (R004)
transmits an audio signal over fiber channel 6 “Fb 6”, and
this signal reaches the Red R2 (R005), the Yellow R2
(R001) and the Green R2 (R002). The Green R2 (R002)
replaces the signal on fiber channel “Fb 6” by another
audio signal, and this audio signal reaches the Blue R2
(R003) and the Orange R2 (R004).

-Fiber channel 7 (Fb 7): Fiber channel 7 (Fb 7) is used by all R2’s. Every R2
receives and transmits an audio signal over this channel.
This way, every R2 can use a source of the previous R2
and replace it by another signal which can be received by
the next R2 in the ring network.

- Fiber channel 8 (Fb 8): Same as channels “Fb 2” and “Fb 3”, the Red R2 (R005)
transmits an audio signal over fiber channel “Fb 8”. This
signal reaches all devices and can be used by all devices.

Setting up the project

This chapter describes a step by step setup procedure which teaches you how to
configure an R2 setup with multiple devices as shown on the previous pages.

NOTE

Don’t make any ethernet or fiber connections until this point. The setup should be configured
in the same sequence as described in this step by step guide.

1) Configuration of R2 Address

The first thing which should be done, is configuring the IP and bus addresses of all
devices used in your setup. When devices are cascaded through fiber, the control can be
done in two different ways:

Method 1:

Connect one device to Ethernet, and control the other devices in your setup through
the same IP address. The data will be transferred between the devices over the fiber
conductor. The advantage of this method is: Only one Ethernet connection is necessary.
The disadvantage of this method is: you can only see the VU meters in the user interface
of the R2 which is directly connected to the Ethernet network. (All other settings can me
made, except the VU meter bar graph which is only visible for the direct connected R2)

To configure your system according to Method 1, proceed with the following procedure:

1) Connect the first R2 of your setup to your Ethernet network

2) Set the address for the first R2 to “R001”, this can be done in the “Setup” menu,
under “R2 Address Settings”.

3) Disconnect the first R2 of your setup from the Ethernet network

4) Connect the second R2 of your setup to your Ethernet network

5) Set the address for the second R2 to “R002”, this can be done in the “Setup”
menu, under “R2 Address Settings”.

6) Disconnect the second R2 of your setup from the Ethernet network

7) Repeat this procedure for all R2’s in your setup, and assign an unique bus address
to every R2 in your setup.

8) After this is done, all R2’s should have an unique bus address, and no R2 is longer
connected to the Ethernet network.

9) Connect one of the R2’s in your setup to the Ethernet network. (It doesn’t matter
which one you connect to the Ethernet network, but mind you can only see the VU
meter bar graph moving of the connected R2)

10) Connect the R2’s with each other through fiber conductors, using the loop
principle as shown in Figure 1.

11) Restart all R2’s

12) All R2’s should display now “Fiber OK” on top of their main page, next to the
connection status.

Method 2:

Connect all devices to Ethernet, and control them by their own IP address. The advantage
of this method is: you can see the VU meters of all connected R2’s. The disadvantage of
this method is: every device needs his own Ethernet connection and IP address.

To configure your system according to Method 2, proceed with the following procedure:

52

1) Connect the first R2 of your setup to your Ethernet network

2) Set the address for the first R2 to “R001”, this can be done in the “Setup” menu,
under “R2 Address Settings”.

3) Change the IP address for the first device to one which is available in your
ethernet network (For example 192.168.0.191). This can be done in the “Setup”
menu, under “Network Settings”.

4) Disconnect the first R2 of your setup from the Ethernet network

5) Connect the second R2 of your setup to your Ethernet network

6) Set the address for the second R2 to “R002”, this can be done in the “Setup”
menu, under “R2 Address Settings”.

7) Change the IP address for the second device to one which is available in your
ethernet network (For example 192.168.0.192). This can be done in the “Setup”
menu, under “Network Settings”. Make sure this IP address is different from the
first device’s IP address.

8) Disconnect the second R2 of your setup from the Ethernet network

9) Give all the R2’s in your setup an unique bus and IP address. This can be done by
repeating step 5 to 8 of this procedure. Make sure every device has an unique bus
and IP address.

10) Now, all devices have an unique bus and IP address, and no device is connected
to the Ethernet network.

11) Connect all devices to your ethernet network

12) Connect the R2’s with each other through fiber conductors, using the loop
principle as shown in Figure 1.

13) Restart all R2’s

14) All R2’s should display now “Fiber OK” on top of their main page, next to the
connection status.

Example setup with 5 R2’s, on the left side with only one Ethernet connection (Method 1) while on the right

side every R2 has a separate ethernet connection (Method 2)

2) Configuration of Fiber channels

The next step is the configuration of the audio channels transmitted over the fiber
conductor. This can be done in the “Setup” menu, under “Fiber settings”. Below, we’ll give
a step by step guide about the fiber configuration for one device in your setup. Let’s start
with the first R2 with address “R001” (indicated in Yellow) in your setup.

1) Open the user interface of the selected R2 “R001”.

2) Open the “Settings” menu and click the “Fiber Settings” button.

3) As shown in figure 1, “R001” transmits audio signals over fiber channel “Fb 4”
and “Fb 7”. For all the other fiber channels, “R001” just send the incoming data
to the next R2. So a source signal should be selected for fiber channels “Fb 4”
and “Fb 7”. All signals available on the R2 can be selected by means of the
dropdown list. For all other channels where the incoming data is just send to the
next R2, status “off” should be selected in the dropdown list.

4) Repeat this procedure for all R2’s in your setup

5) After this is done, all selected audio signals are transmitted over the fiber
conductor, and can be
used by other R2’s in your setup.

3) Set passwords

You can skip this step if the default password “R2” for administrator and “user” for users
is OK for you, but we always recommend to change the passwords. A detailed description
how the passwords can be changed can be found inside an earlier chapter of this user
manual. It’s convenient to give all the R2’s in your setup the same administrator password,
making it possible to swap between R2’s without constantly reentering the password. At
user level, it’s always necessary to reenter the password after swapping between R2’s.

4) Connecting sources

Connect all your audio sources (CD-players, Tuners, ... ) to the line inputs on the back of
the R2. Adjust all input gains so there is no clipping. More information about connecting
source is extensively described in an earlier chapter of this user manual.

54

5) Connecting wallpanels

Connect all your wallpanels to the Peripheral inputs on the rear of the R2. A detailed
description about connecting wallpanels is extensively described in an earlier chapter of
this user manual.

6) Ready

Your project is now ready for use.

Additional information

IP Basics

Many AUDAC products are controllable by Ethernet. The Ethernet connection which is used
on the AUDAC products is Transmission Control Protocol (TCP) & the Internet Protocol (IP)
(TCP/IP) based. There are some basics which you need to know to successfully make a TCP/
IP Ethernet connection.

Nearly all computers today support TCP/IP. TCP/IP is not a single networking protocol – it is
a suite of protocols named after the two most important protocols or layers within it – TCP
an d I P.

As with any form of communication, two things are needed: a message to transmit and
the means to reliably transmit the message. The TCP layer handles the message part. The
message is broken down into smaller units, called packets, which are then transmitted over
the network. The packets are received by the corresponding TCP layer in the receiver and
reassembled into the original message.

The IP layer is primarily concerned with the transmission portion. This is done by means of
a unique IP address assigned to each and every active recipient on the network.

TCP/IP is considered a stateless protocol suite because each client connection is newly made
without regard to whether a previous connection had been established.

The IP address is always a number in the following format “192.168.000.001”. As you can
see, this address consists of 4 separate numbers ranging from “000” to “255”.

In simple terms, only the latest number of an IP address can be different within a network,
so there is a maximum of 256 unique addresses within a network, ranging from “xxx.
xxx.xxx.000” to “xxx.xxx.xxx.255”. The first three numbers must be the same to make
communication between several devices possible, else the devices can not communicate
with each other.

Example:

Device 1: IP address: 192.168.000.001
Device 2: IP address: 192.168.000.002
Device 3: IP address: 192.168.001.003

In this example, Device 1 can communicate with Device 2, but not with Device 3, because
the first three numbers must be the same. These first three parts are called the “IP
range”, so the devices must be in the same “IP range” to communicate with each other.

The “IP range” of home and office networks are defined by the network administrator,
this means that the IP range of your home or office network can be different from another
network. AUDAC products have the following IP address as default: “192.168.0.xxx”, this
means the standard IP range of AUDAC products is “192.168.000.xxx”. If your network is
using a different IP range, the AUDAC products will not be accessible from your network.
You can change the IP address of the AUDAC products to make them work properly in

56

your network. This can be done in the settings menu, and is described extensively in the
“Settings” chapter of this user manual.

Of course, to make changes to the settings menu of the AUDAC products, you must have
access to the user interface on the products webpage. This can be done by temporarily
giving your computer an IP address within the IP range of the AUDAC product, for
example “192.168.0.200”. After the IP address of your computer is within the IP range
of the product, the user interface is accessible and the IP address of the product can be
changed to an IP address within the IP range of your network. If the IP address of the
product is within the IP range of your network, you can change the IP address of your
computer again to it’s former IP address and the product should work properly in your
home or office network.
Ask your network administrator for help if you are not familiar with networks.

Summary

- All devices must have an unique IP address

- All devices must be within the same IP range

Updating the R2

New features and improvements will be continuously added to the R2’s software.
It is therefor recommended to always keep your R2 running on the latest software version
to have optimal performance and most reliable experience under all circumstances.

For more information about the latest available updates and the step by step procedure
how this software update should be performed, please check our website.

The easiest way to keep your R2 device up to date is through the Audac System Manager.
