Mixers, Source Selectors & Switchers - RB- SS10

1 RB-SS10 10 Way Stereo Analogue Source Selector/Mixer
Introduction
Fig 1-1: RB-SS10 Front Panel
The RB-SS10 10 Way Stereo Analogue Source Selector/Mixer is a 1U
rack-mount unit that produces a stereo analogue audio output from 10
selectable stereo analogue sources. There are 10 illuminated front panel
push buttons, which select and indicate the current channel selection. The
selection and indication is also available through a remote connector on the
rear panel. To stop accidental front panel selection there is a remote input
to inhibit the front panel buttons.
As well as being able to act as a source select module, the RB-SS10 can act
as a mixer, by enabling the mix mode (using the remote input).
The front panel headphone output has its own volume control, which
is independent of the level adjustment for the main outputs, and has a
maximum output level of +12dBu. The volume control can be made to also
alter the output level of the main XLR outputs by using a switch on the rear
panel to enable/disable this feature.
There is a designation strip on the front panel, useful for giving the buttons
a meaningful description. The strip covers the input gain controls so that
once configured, they can’t easily be altered – ideal for installation work.
The LED on the front panel is used to indicate that power is present on the
unit.
The gain for left and right inputs can be individually adjusted by using the
preset potentiometers on the front panel.
As well as routing the selected audio signal, the unit will also route a
remote signal input through the remote connector to the selected input
source, for starting external audio equipment such as a CD player.

Illuminated Push Buttons
The front panel contains 10 illuminated push buttons, used for selecting an
analogue source. The push button illuminates when the input is selected.
The status of pin 12 on the remote connector determines whether the unit
is in the selector mode, or the mix mode. When pin 12 is connected to 0V,
mix mode is enabled.
In selector mode, one push of a button will select the desired analogue
stereo source and pushing the button again will turn it off.
In mix mode, each button you press will select that source allowing
multiple sources to be mixed to a single output. Pressing the button again
will switch off a source.
There is also a remote input to inhibit the front panel switches. When the
front panel inhibit is active, pressing the front panel switches has no effect
on the current channel selection.
Front Panel Gain Controls
The input gain can be individually adjusted for left and right channels
through pre-set potentiometers which are accessible through the front
panel. The gain range of the input is -8dBu to +20dBu.
Headphone Output
The front panel headphone output is a ¼” stereo jack socket and is designed

Volume Control
The volume control is used to alter the headphone output. It can also be
used to alter the main XLR output levels by using a rear panel switch to
enable/disable the control.

mode and Protected Alternate mode: Alternate Mode
In this mode the channels are selected and deselected by a press of the
button, as described previously.
Latched Mode
In this mode the selected channel is active only while the button is pressed.
As soon as button is released the channel becomes inactive.
Protected Alternate Mode
Operates in a similar manner to the Alternate mode, but a channel cannot
be turned off unless switching to another input or while operating in mixmode and there is more than one channel active. In other words, there will
always be a channel routed to the output. NOTE: after setting this mode
there will be no channel selected.
Configuring the Additional Modes
While the unit is powered, hold down the input 10 button and press the
input 5 button five times. Once completed, the input 10 button will start
to flash and the first 3 input buttons will display the current operating
mode (as shown below). To change the mode, simply press the input 10
and the buttons will indicate the newly selected mode. Once the required
operating mode has been set the unit will restart within five seconds from
the last button press.

Inputs
Two of the stereo analogue audio inputs are on XLR-3 pin sockets (female)
so that they can be used for equipment which you may want to plug/unplug
on a regular basis and isn’t
pre-wired, e.g. portable recorders.
The four XLR-3 inputs can take balanced professional levels, or unbalanced
by using the front panel gain controls, and by connecting the non-phase to
the signal ground. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Outputs
The two XLR 3 pin outputs are electronically balanced, and can be wired
unbalanced. Each output is individually buffered so that a short circuit on
one output will not affect the others. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase

Altering the Master Output Level
When the Output Level Control push-switch is Enabled (pushed in) on the
rear panel, it changes the functionality of the front panel volume control to
also alter the level of the master output, as well as the headphone volume.
RB-SS10 Additional Audio Input Connectors
There are 2 off 25 way D-type sockets (female) used for the remaining audio
inputs.

2 RB-DSS10 10 Way Stereo Digital Source Selector
Introduction
Fig 2-1: RB-DSS10 Front Panel
The RB-DSS10 10 Way stereo Digital Source Selector is a 1U rack-mount
which produces an AES/EBU and S/PDIF level digital audio output from 10
selectable AES/EBU or S/PDIF digital input signals. There are 10 illuminated
front panel push buttons, which select and indicate the current channel
selection. The selection and indication is also available through a remote
connector on the rear panel. To stop accidental front panel selection there
is a remote input to inhibit the front panel buttons.
The digital receivers in this unit are fully 24 bit, 96kHz capable. When an
input is selected from the front panel, or remotely, the unit will attempt
to capture the incoming signal on either the AES/EBU or the S/PDIF signal
inputs, with priority given to the AES/EBU input. If the AES/EBU signal
becomes locked while the S/PDIF signal is routed, the unit will automatically
switch to the incoming AES/EBU signal.
The headphone output has its own volume control, which is independent of
the level adjustment for the main outputs, and has a maximum output level
of +12dBu.
As well as routing the selected audio signal, the unit will also route a
remote signal input through the remote connector to the selected input
source, for starting external audio equipment, such as a CD player.
There is a designation strip on the front panel, useful for giving the buttons
a meaningful description.
The LED on the front panel is used to indicate that power is present on the
unit. However, it also has a secondary role to indicate whether the selected
channel is routing the AES/EBU (red LED) or S/PDIF input (amber LED).
Once the receiver has successfully locked to a digital input, the LED
illuminates, the tally is made, and the audio is routed simultaneously
to both the digital audio outputs and converted to analogue audio for
monitoring on the front panel headphone socket. If the incoming audio
signal is not present, the push button LED and remote tally flash to indicate
that the incoming digital signal is missing.

Power Indicator
The LED on the front panel is used to indicate that power is present on the
unit. However, it also has a secondary role to indicate whether the selected
channel is routing the AES/EBU or S/PDIF input:
Red indicates AES/EBU input.
Amber indicates S/PDIF input.
The LED and remote tally flash, if the incoming audio signal is not present,
to indicate that the incoming digital signal is missing.
Illuminated Push Buttons
The front panel contains 10 illuminated push buttons, used for selecting a
digital source. The push button illuminates when the input is selected and
flashes when the selected input loses lock.
There is also a remote input to inhibit the front panel switches. When the
front panel inhibit is active, pressing the front panel switches has no effect
on the current channel selection.
Headphone Output
The output available on the front panel through a ¼” stereo jack socket, is

Volume Control
The headphone output has its own volume control and has a maximum
output level of +12dBu.
Additional Modes
An option to set the unit in different modes of operation is available and
can be configured at anytime while the unit is powered.
2
Alternate Mode
In this mode the channels are selected and deselected by a press of the
button, as described previously.
Latched Mode
In this mode the selected channel is active only while the button is pressed.
As soon as button is released the channel becomes inactive.
Protected Alternate Mode
Operates in a similar manner to the Alternate mode, but a channel cannot
be turned off unless switching to another input. In other words, there will
always be a channel routed to the output. NOTE: after setting this mode
there will be no channel selected.
Select & Confirm Mode
In this mode, input button 10 acts as a CONFIRM button for input selection
1 to 9. Once one of the inputs is pressed, this selection will then flash along
with button 10. You must press button 10 within 5 seconds to confirm the
selection or the original input selection times out. Only inputs 1 to 9 are
selectable and there is always an input channel routed in this mode. NOTE:
Initially, after setting this mode there will be no input selected.
Configuring the Additional Modes
While the unit is powered, hold down the input 10 button and press the
input 5 button five times. Once completed, the input 10 button will start
to flash and the first 3 input buttons will display the current operating
mode (as shown below). To change the mode, simply press the input 10
and the buttons will indicate the newly selected mode. Once the required
operating mode has been set the unit will restart within five seconds from
the last button press.
There are currently three modes of operation: Alternate mode, Latched
mode and Protected Alternate mode: -

RB-PMX4 10 Input, 4 Output Analogue Preset Mixer
Introduction
Fig 3-1: RB-PMX4 Front Panel
The RB-PMX4 is a high performance 10 mono input to 4 mono output
preset mixer. Each of the four outputs has a 10 way DIP switch associated
with it to select which of the 10 inputs are routed to it. So, by altering the
DIP switches, any of the input sources can be mixed to any of the outputs.
The DIP switches are enclosed by a screw-on cover on the front panel so
that the settings can not be accidentally changed for secure applications.
The RB-PMX4 has been designed for situations where a small mixer is
needed for installations where it will be configured and then only altered
occasionally, or never altered. Uses for this product are numerous including
a four bus mini-mixer, a 4 zone mixer for pubs and clubs, a multiple cleanfeed generator and a quad stereo to mono converter to name
a few.
The XLR-3 inputs and outputs are electronically balanced and can be wired
unbalanced. Each output is individually buffered so that a short circuit on
one won’t affect the others. Each input has its own gain control which is
a pre-set potentiometer accessible through the front panel. This provides
gain adjustment of -8dB to 18db. This is useful for normalizing consumer
and professional signals to give outputs of -15dBu and 0dBu respectively.
16
The front panel is held on by 2 off M3 x 6 stainless steel dome-head screws
and can be removed using a 2mm AF hex key (allen key). Each 10-way
switch represents an output and the individual switches represent the
inputs that will be mixed to that output. Switches are in the ON (down)
position to be mixed and the OFF (up) position for off.
The XLR-3 outputs are electronically balanced and can be wired
unbalanced. Each output is individually buffered so that a short circuit on
one won’t affect the others.
An LED power indicator on the front panel displays the power supply
connection.

Mixers, Source Selectors & Switchers - RB- DMX4
4 RB-DMX4 4 x 4 Channel Digital Audio Mixer/Router
Introduction
Fig 4-1: RB-DMX4 Front Panel
The RB-DMX4 is a digital mixer capable of mixing or routing 4 mono input
channels into 4 mono outputs, or 2 stereo inputs into 2 stereo outputs. The
inputs are sample rate converted to allow sources of different sample rates
to be mixed. The flexible Mix Matrix allows for a wide variety of mixing
options and creativity, using 4 blocks of 4 way DIPswitches to select which
inputs are mixed or routed to which outputs.
The RB-DMX4 has 4 x digital mono audio inputs, each one selectable in
pairs via front panel INPUTS 1 & 2 and INPUTS 3 & 4 push buttons, from
either AES/EBU balanced XLRs, S/PDIF unbalanced phonos or TOSlink
unbalanced optical inputs. Sample rate converters on each input mean that
sources of different sample rates can be used with the output sample rate
being defined independently. The colour of the INPUTS 1 & 2 and INPUTS
3 & 4 push-buttons indicate whether the input source is synchronised (no
colour) or not (flashing green and red).
Each input has a trim pot, which can be used to attenuate the input signal.
This allows for a perfect mix of channels at different audio levels. Audio
presence LEDS around each input button give an indication of input audio
level. There is one LED for each channel. There are also 4 presence LEDS
around the MONITOR button which give an indication of output level.
Additional gain can be added by accessing the OUTPUT GAIN mode.
There are 2 stereo outputs which are available as simultaneous AES/EBU
20
balanced XLRs, S/PDIF unbalanced phonos or TOSlink unbalanced optical
outputs. The output sample rates are selectable via rear panel DIPswitches
from one of 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz or 192kHz.
The unit has TTL wordclock BNC and AES/EBU XLR synchronising inputs
as standard and optionally, the RB-SYA and RB-SYD synchronisation
boards can be fitted to synchronise the unit to analogue or digital video
signals. A rear panel DIPswitch block is used to decide whether the unit
is synchronised to Input 1 & 2, Input 3 & 4, the AES/EBU sync input, the
wordclock sync input or an optional video sync board. The DIPswitch block
also selects the synchronisation mode of the unit and the MONITOR button
flashes whenever the unit is not synchronised to an incoming sync signal.
Selectable sync modes are as follows:
Master Mode
In this mode the digital output sample rate is simply set by, and locked to,
the internal on-board clock generator. No sync signal is used or required.
Auto Sync Mode
In this mode the digital output sample rate follows the selected sync input.
When the sync signal is not present the output sample rate will be set by,
and locked to, the internal on-board clock generator at the selected output
frequency.
Mixers, Source Selectors & Switchers - RB- DMX4
Auto Lock Mode
The digital output sample rate follows the sync input. If the sync signal is
removed then the output sample rate will be set by, and locked to, the
internal on-board clock generator at the closest frequency available to the
previous sync input.
Slave Mode
In this mode the digital output sample rate follows the sync input. When
the sync signal is not present the digital output is turned off.
There is a monitor socket on the front panel with a gain pot to allow you
to monitor the output of each channel. The monitored channel can be

AES
selected via a push button on the front panel which, when held, can also
supply up to 12dB of gain. If the level that is being monitored is close to
full scale, a 12dB attenuation can be added to the monitor channel via a
DIPswitch on the rear panel.
The unit can be placed in mono or stereo mode via rear panel DIPswitch.
Stereo mode allows you to monitor the two input pairs as stereo channels
as well as controlling the input gain as a pair, giving tied audio levels.
The RB-DMX4 has been designed to have a passive signal path through the
main input, so if power to the unit fails, signal inputs 1 & 2 are routed to
outputs 1 & 2 and signal inputs 3 & 4 are routed to outputs 3 & 4. This is

essential for applications such as installation at transmitter sites, where a
power failure to the unit should not prevent the audio input signal from
being output to the transmitter. Please note that this is not true for the
TOSLink outputs which are muted.
This allows many mixing configurations and maximum
flexibility. Adding to that, mixing can be achieved between all
the different input types at all sample rates. See page 24 for
applications for the product using different matrix settings.
The RB-DMX4 can be controlled using Sonifex free software, SCi. Contact
Sonifex for further information if you have a particular requirement that
isn’t catered for by the RB-DMX4 as standard.

Output Mix Matrix Selection Using The Front Panel DIPSwitches
The OUTPUT MIX front panel DIPSwitches are concealed behind the screw
panel located on the front of the unit and they decide which input channels
are mixed to which output channels. There are 4 banks of DIPSwitches,
each representing an output channel.
To mix an input to that channel, simply lift the DIPSwitch for the desired
input channel. In total, 4 mono channels can be mixed together on each
mono output channel.

button illustrate which source is selected. The button also
indicates whether the input is locked - it flashes green and red
if the input is unlocked and is unlit when locked.
The bicolour LEDs, marked ‘1’ and ‘2’ , show input presence
and give an indication of the input level using the AES digital
standard with the following colours:
-INF < -52dBFS = OFF
-52dBFS < -3dBFS = GREEN

INPUT GAIN Pots
These pots allow the gain of each individual channel to be trimmed so that
the perfect mix can be achieved. Simply turn anti-clockwise to attenuate
the level or clockwise to restore it. Fully clockwise is unity gain. Fully anticlockwise is muted.
In Stereo Mode, pots 1 and 3 control the gain for channels 1 & 2 and 3 & 4
respectively. See page 25 for further information.

MONITOR Button
The MONITOR button has three modes of operation with different
functions: Display Mode, Monitor Output Select Mode and Output Gain
Mode:
Display Mode
Display Mode is the default mode of the button. In display mode, the four
surrounding bicolour LEDs act as presence LEDs for the output channels.
Marked ‘1’ to ‘4’ , the LEDs give an indication of the output level using the
AES digital standard with the following colours:
Fig 4-6: RB-DMX4
INPUT Gain Pots
MONITOR Button & Output Presence LEDs
Normally, this button displays the external synchronisation status and the
four LEDS around it display output presence. If the selected synchronisation
source is unlocked, the button will flash green and red. A button press
allows you to choose which channel is output through the headphone
socket and to set-up the output gain.
For monitor selection, the button illuminates red, as does the LED of the
selected channel. For output gain, the LEDS around the button illuminate in
green sequentially indicating the level of gain applied.
-INF < -52dBFS = OFF
-52dBFS < -3dBFS = GREEN
-3dBFS <0dBFS = ORANGE
0dBFS/ CLIP = RED (AGC Operational)
Note re Clipping: The AGC is working on a channel if its output presence
LED is red. The mixing in this unit is achieved by the summation of 24 bit
audio values. The total of this summation could, if uncorrected, breach
the upper limit of a 24 bit number, which would lead to clipping. The unit
detects these occurrences and adds an instantaneous attenuation to bring
the signal in range again. This attenuation factor will decrease on a slow
decay until 0dBFS is achieved, or until another breach occurs. The slow
decay eliminates any breathing or pumping effects in the audio.
If the unit is set to be synchronized externally but is not synchronized, the
button flashes green and red continuously. If it is synchronised, or the unit
is set to MASTER sync mode, the button is unlit.

Please be aware that this headphone amplifier has
been designed to cope with the varying different
headphone and full scale line-up set-ups that
are used. Consequently, the monitor attenuation
DIPSwitch 10 should be turned on if the output
sounds very loud and distorted at any time.
After choosing your required setting, press and hold the button until it
changes colour from solid green. This will return the button to the Display
Mode.

Fig 5-1: RB-SSML1 Front Panel
The RB-SSML1 is a 1U rack-mountable source selector for compressing or
limiting an incoming microphone or stereo line signal and mixing this signal
with a stereo monitor input, which can then be metered and mixed to
two headphone outputs. The unit is mainly used in situations where level
control is required, for example in voiceover applications.
The XLR-3 stereo monitor input has an adjustable volume control via a back
panel recessed pot, and has an additional 10dB gain increase via a switch
on the rear panel, for use with unbalanced equipment. The audio on this
input is only present on the headphone outputs, and is therefore suitable as
a return feed from a codec, a PC audio output, or similar equipment.
The mic input consists of an independent low-noise microphone preamplifier for converting microphone level signals to a line level. There are
independent switches to control a high pass filter (low frequency rolloff at 125Hz) and to provide phantom power at +48V to the connected
microphone. A preset pot on the rear panel allows adjustment of the mic
gain from 36dB to 75dB.
The compression ratio and threshold limits of the compressor/limiter
section are fully adjustable via linear pots situated on the front panel.
The threshold can be set between -30dBu and +20dBu. When the input
signal rises above the threshold level a soft-knee compression is applied
at the selected ratio. The compressor has an attack time of approximately
20ms and a release time of approx 400ms, and can operate at ratios of
ϭ͗ϭ;ŶŽĐŽŵƉƌĞƐƐŝŽŶͿƚŽь͗ϭ;ůŝŵŝƚŝŶŐͿ͘ĨƌŽŶƚƉĂŶĞůzW^^ƐǁŝƚĐŚĐĂŶ
be used, where no compression is applied. A rear-panel DIPswitch allows
compression only to be applied to the mic input and not the stereo line
input.
A front panel switch selects between mic and line inputs. Both mic and line
inputs have fully adjustable volume control via front panel pots, with the
line input having an additional 10dB gain increase via a switch on the rear
panel for use with unbalanced equipment. The mono mic input is converted
to a stereo signal before being passed to the compressor/limiter.
36
Mixers, Source Selectors & Switchers - RB- SSML1
The metering is carried out after the compressor/limiter section and
consists of two rows of 12 round LEDs showing levels between -17dB and
+11dB. An internal jumper allows the metering to follow either the stereo
output, or the headphone monitor outputs and a rear panel DIPswitch can
disable the peak hold display.
The XLR-3 stereo line output can be fed from either the mic or line input,
but not the stereo monitor input. The line output is electronically balanced
and can be wired unbalanced by grounding the non-phase signal, allowing
5
you to feed both balanced and unbalanced equipment. A pushbutton
switch is provided to reduce the output by 10dB for this purpose.
The headphone output volume control is on the front panel. Each

Stereo Monitor Inputs
The 2 x XLR 3 pin sockets used for the monitor input are electronically
balanced. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Note: The monitor input can not be mixed to the stereo line output, it is
only used for headphone monitoring.
Stereo Monitor Pad & Volume Control
A 10dB gain pad is available by depressing the rear panel switch, for
handling connection from unbalanced outputs. A MONITOR VOLUME
control is available as a pre-set potentiometer, located on the back panel.
The monitor input channel with the volume control fully up, has a gain of
+6dB.
Mic Input
The XLR 3 pin socket used for the microphone is electronically balanced. It
has the following connections:
38
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Mic Input Gain
A recessed GAIN pre-set potentiometer allows for adjustment of the gain
of the microphone input. This provides a gain range of 36dB to 75dB which
enables the use of dynamic and powered microphones. Connect the mic
input and adjust the gain until the line output is at the required level. The
front panel MIC VOLUME reduces the volume to –80dB.
Using Phantom Powered Microphones
For the microphone input channel there is a switch to provide phantom
power at +48V to the connected microphone. With phantom power
selected, a voltage of +48V is applied to pins 2 and 3 of the XLR connector
to power the microphone, supplied through 6k8 resistors giving a current
of 14mA. Phantom power is enabled when the switch is pointing towards
the arrow.

Bypass Button
The compressor/limiter section of the product can be switched in and out
by using the BYPASS button.
Applying Compression
Compression is applied by setting a threshold at which the compressor
begins to operate, and a compression ratio to which all audio above the
threshold will be compressed. To enable the compressor, release the unit
from bypass mode (ensure the bypass LED is off).
The compression ratio and threshold limits of the compressor/limiter
section are fully adjustable via the COMPRESSION and THRESHOLD linear
40
pots situated on the front panel. The threshold can be set between -30dBu
and +20dBu. When the input signal rises above the threshold level a softknee compression is applied at the selected ratio. The compressor has an

The compressor is temperature sensitive and in cold conditions may take a
short time for the threshold levels to settle. In any case you should always
allow the unit to fully come to its normal operating temperature before
setting the threshold level.
LED Metering
The metering is carried out after the compressor/limiter section and
consists of two rows of 12 round LEDs showing levels between -17dB and
+11dB.
The LED meter source can be set to either the output, or a mix of the
output and the monitor input (i.e. the audio present on the headphones).
The default setting is a mix of the output and monitor input. This can be
changed by altering the setting of jumpers J1 and J2 inside the unit.

Fig 6-1: RB-OA3 Front Panel
The RB-OA3 is a 1U rack-mount, unity gain on-air switcher, capable of
switching three stereo pairs between three studios. Each studio can control
the transmission path together with two peripheral paths for equipment
such as a codec or hybrid and there is also a last studio to offer (LSO) bus,
allowing for seamless and continuous broadcast from any multi-studio
radio network. A sustain mode allows for a sustaining system, such as a PC
automation system, to control the broadcast. Multiple RB-OA3 units can be
connected together to switch more studios or more stereo pairs.
The switching is achieved using relays, except the last studio to offer which
is switched by an analogue switch. The transmission path is switched using
latching relays. This means that if there is a power failure to the unit, the
transmission path will remain selected.
All studios are connected using 25 way D-types for electronically balanced
audio signals and control is achieved using 15 way D-types, connecting to
an external control unit such as the Sonifex S2-MTBS mixer control panel or
the RB-OA3R remote switcher panel.
A transmission mix connection is included to mix into the transmission
path audio which is generic to all studios. This could be used for jingles or
42
adverts for example. The RB-OA3 also allows for the control of a profanity
delay to be shared by all connected studios.
Each studio has the ability to offer the transmission. Once offered, the
transmission is fed to the other studios via the last studio to offer bus. By
adding the LSO bus as an input to the mixer, the next scheduled station can
then fade in the transmission and accept at the appropriate time meaning
the transmission can be continuous.
The sustain mode can be used to control an automated studio, such as a
PC based overnight music system which conventionally wouldn’t be in its
own studio and would therefore need external control to take transmission
back from it. Think of it as a studio which has no Offer and Accept controls
of its own, but which can still be put to and from transmission by the other
studios.
The RB-OA3 can be expanded to switch between up to 5 studios or up to 6
stereo pairs by connecting a multiple of units together. With the addition
of a single unit, expansion in studio mode allows for 2 additional studios
to take control of the transmission path and additional equipment. If the
expansion is made in bus mode, then three additional stereo channels can
Mixers, Source Selectors & Switchers - RB- OA3
6
be added. In total 4 x RB-OA3 units can be connected together to switch 6
stereo pairs between up to 5 studios. An optional cable kit, the RB-OA3C, is
available to connect expansion RB-OA3 units to a master RB-OA3.
The modes are configured by dip switches on the rear of each unit. Two dip
switches control the unit ID and two switches control whether the unit is in
studio or bus mode.
A master unit, defined by a preset ID, conducts all communication between
all units.

Installation Guide for the RB-OA3
Setting the Unit’s Identity Using The Mode ID DIP Switches
Multiple RB-OA3 units can be combined to offer expansion of either
the number of studios (STUDIO EXPANSION), or the number of stereo
audio pairs available to switch (BUS EXPANSION), or both (STUDIO & BUS
EXPANSION). Up to 4 units can be connected together and each unit will
have a different Mode ID.
The identity of the unit is defined by setting the first two MODE ID DIP
switches as per the following table:

Fig 6-4: RB-OA3 Unit Identity Definitions
If you have just a single RB-OA3, define it as the MASTER, i.e. DIP switches
1 and 2 set to OFF. For more information on the expansion modes, see page
46.
If you would like to change the identity of a unit, it will have to be reset.
Note: The recommended time to change the unit ID is on power down.
44
Mixers, Source Selectors & Switchers - RB- OA3
Setting The Boot Up Mode
On first powering up the RB-OA3, the unit will default to giving transmission
control to Studio 1. The third DIP switch controls what studio the unit will
boot to on subsequent initialisations. The different modes provided are:
OFF
This will set the unit to Force Last Used Studio mode
ON
This will set the unit to Force Studio 1 mode
Fig 6-5: RB-OA3 Unit Identity Reset Settings
Force Last Used Studio Mode
When a studio is selected, the value of that studio is stored in the unit.
This is then recalled on boot up so that the last studio to transmit is
reconnected. This is useful in loss of power situations, since the latching
relays will remain in position on start up, leaving the transmission path
unaffected.
Force Studio 1 Mode
On boot up Studio 1 is given transmission control. This is useful for
returning the unit to a known position.
Note: When connecting multiple units together ensure that there is
only one of each type of unit. If you connect units of the same type,
communication errors will occur. For security, once initialized, the unit will
retain its ID until power down regardless of any DIP switch changes.
Configuring for Operation
The RB-OA3 can be used in both single (MASTER) and multiple expansion
modes.
6
Studio Connections
Each connector has a dedicated channel for the master transmission and
for each of the two additional balanced stereo channels. The connector
also provides the Last Studio to Offer (LSO) feed. The Transmission path is a
latched pathway so that it will remain even if there is no power supply. For
this reason, the transmission output of your mixer should always be routed
to this channel. The peripheral channels are non-latching.
Control Panels
Connect the chosen control panels, such as an RB-OA3R, one to each
STUDIO CONTROL port. The control ports are designed to allow 200mA at
15V from each chosen connector.
An excess will cause a polyfuse to cut the voltage supply which can be reset
by removing the load.
Profanity Delay Connector
You can control a profanity delay connected to the unit. The control pulses
are relay based and can be wired either normally open or normally closed,
to route a common signal.
Mix Input
If the mix input is to be used, connect the source to the unit. If not, the
socket must be terminated, or the MIX INPUT ON/OFF switch must be OFF,
otherwise the output signal may experience a loss of level (see page 53 ).
LSO Expansion Port
Leave disconnected.
Serial Ports
Leave these disconnected.
Single (MASTER) Mode
When used as a single (MASTER) unit, the RB-OA3 is used to switch 3 stereo
busses between 3 studios, allowing them to share the same transmission
path and peripheral devices such as hybrids or profanity delays. A single
unit must always be configured as a MASTER unit.

one unit as the MASTER and one unit as the STUDIO EXPANSION:
Studio Connections
Connect three studios to the master unit and connect the MASTER RB-OA3
TRANSMISSION OUTPUT to the STUDIO 1 AUDIO input of the STUDIO
EXPANSION RB-OA3 using a transmission expansion cable (available in the
RB-OA3C cable pack). Then connect studios 4 and 5 to the STUDIO 2 AUDIO
and STUDIO 3 AUDIO connectors on the STUDIO EXPANSION SLAVE unit.
The TRANSMISSION OUTPUTS port of the STUDIO EXPANSION unit is the
main output of this system.
Control Panels
Connect three control panels to the MASTER STUDIO CONTROL PORTS
1 - 3, one for each studio. The control panels for studio 4 and 5 need to be
connected to the STUDIO 2 CONTROL and STUDIO 3 CONTROL ports of the
STUDIO EXPANSION unit.
46
Profanity Delay Connector
A profanity delay can be connected to either of the two units. However, it
is recommended that it is connected to the MASTER. See Single (MASTER)
Mode set up for more information.
Mix Input
The mix input must be connected to STUDIO EXPANSION unit to ensure
that the mix input is on all five studios. Ensure that the MASTER mix input is
terminated correctly or that the MIX INPUT ON/OFF switch is OFF.
LSO Expansion
The LSO feed needs to travel between the units. Do this by connecting the
LSO expansion ports on each unit with an LSO expansion cable (available in
the RB-OA3C cable pack).
Serial Ports

TRANSMISSION OUTPUT to your transmission output destination. The BUS
EXPANSION SLAVE switches as the MASTER.
To access the three extra balanced stereo channels, connect to the
transmission and peripheral paths of the BUS EXPANSION SLAVE
STUDIO 1-3 AUDIO connectors. The outputs for these paths will be the
TRANSMISSION OUTPUT of the BUS EXPANSION SLAVE.
Control Panels
Connect three studio control panels to the MASTER STUDIO CONTROL
PORTS 1 - 3, one for each studio. If control panels are connected to the BUS
EXPANSION SLAVE the LEDS will simply follow the master control panels,
however no action can be initiated with a slave control panel.
Profanity Delay Connector
A profanity delay can be connected to either of the two units. However, it
is recommended that it is connected to the MASTER. See Single (MASTER)
Mode set up for more information.

Studio Connections
Connect the STUDIO EXPANSION SLAVE and the BUS EXPANSION SLAVE
as shown previously to give you a system of three units. The STUDIO &
BUS EXPANSION SLAVE is added as a bus expansion for studios 4 and 5. To
connect this unit, use a second transmission connection cable to connect
the TRANSMISSION OUTPUT of the BUS EXPANSION SLAVE with the STUDIO
1 AUDIO connector of the BUS EXPANSION SLAVE. The TRANSMISSION
OUTPUT from the BUS EXPANSION SLAVE acts as the I/O for all the bus
expansion paths.

connected to STUDIO CONTROL PORTS 2 and 3 of the STUDIO EXPANSION.
There is no need to connect control panels to the BUS EXPANSION SLAVE
and STUDIO & BUS EXPANSION SLAVE although, if connected, they will
reflect the situation shown by the control panels connected to the MASTER
and STUDIO EXPANSION SLAVE units.
Profanity Delay Connector
A profanity delay can be connected to either of the four units. However, it
is recommended that it is connected to the MASTER. See Single (MASTER)
Mode set up for more information.
Mixers, Source Selectors & Switchers - RB- OA3
Mix Input
The mix input must be connected to the STUDIO EXPANSION SLAVE to
ensure that the mix input is on all five studios. Ensure that the MASTER mix
input is terminated correctly or that the MIX INPUT ON/OFF switch is OFF
(see page 53).
LSO Expansion
The LSO feed needs to travel between units. This is achieved by connecting
the LSO expansion ports on the MASTER and STUDIO EXPANSION with an
LSO expansion cable (available in the RB-OA3C cable pack). For the BUS
EXPANSION SLAVE and STUDIO & BUS EXPANSION SLAVE, there is no
need to connect the LSO expansion cables since the LSO is not used in bus
expansion.
Serial Ports
6
Connect the serial ports of the MASTER and all the SLAVE units together
using a standard RJ45 network cable. It is recommended that a full ring
system is implemented by connecting each unit to two others.
This ensures that if one connection is lost, there is still a path for
communication for each unit. If the decision is taken to use three cables
rather than four, please ensure that there is a direct link between the
MASTER and STUDIO EXPANSION SLAVES.

Indications – How The LEDS Are Used
FRONT PANEL LEDS
The unit is supplied with 7 LEDs on the front panel. These LEDs are used to
indicate all the various states of the unit:
CONTROL PANEL LEDS
Each of the control panel connectors has the ability to switch on four LEDS.
In the case of the S2-MTBS and the RB-OA3R, the LEDS are built into the
buttons.
POWER
This LED is used to indicate whether the unit is currently powered. It is
illuminated RED if the unit is powered and extinguished if not.
OFFER
This LED is used to show whether the system is currently in OFFER mode. This
LED is illuminated while the unit is on offer and extinguished otherwise. If this
LED flashes this means that the unit is currently in SUSTAIN ACTIVE mode.
DELAY
This LED is used to show whether the Delay function has been activated.
Its operation is momentary and each burst will last for approximately half a
second. If the button is illuminated RED this means that the delay pulse has
been activated.
DUMP
This LED is used to show whether the Dump function has been activated.
Its operation is momentary and each burst will last for approximately half a
second. If the button is illuminated RED this means that the dump pulse has
been activated.
OFFER
This LED is used to show whether the system is currently in OFFER mode.
This LED is illuminated YELLOW while the unit is on offer and extinguished
otherwise. If this LED flashes this means that the unit is currently in
SUSTAIN ACTIVE mode (see page 51 ).
STUDIO 1-3
These LEDS are used to indicate which studio is currently switched to the
transmission path. Each one is illuminated RED to represent each specific
studio when that studio is switched in. When the unit is operating as a
STUDIO EXPANSION SLAVE, if one of the MASTER unit’s studios is routed
to the transmission path, STUDIO 1 LED will always be illuminated. If one of
SLAVE’S studios is selected, the MASTER unit’s studio indications will all be
extinguished.
50
ACCEPT
This LED is illuminated if the studio is currently on the transmission path. In
SUSTAIN ARMED mode this LED will flash repeatedly until the specific studio
is selected. The ACCEPT LED will always flash to indicate SUSTAIN ARMED
mode.
DELAY
This LED is used to show whether the studio has activated a delay pulse. It is
illuminated when a delay pulse is activated.
DUMP
This LED is used to show whether the studio has activated a dump pulse. It is
illuminated when a dump pulse is activated.
EMERGENCY MODE
If the MASTER loses contact with any of the SLAVES, the SLAVES will enter
emergency mode. In emergency mode all the LEDS except the power led will
flash repeatedly until contact with the master is re-established.
Operational Modes
OFFER
If a studio is transmitting, this mode is used to offer the transmission path
to other studios. When the OFFER button is pressed, the OFFER button in all
studios is illuminated. This unlocks the operation of the ACCEPT button in all
other studios. To remove this mode, simply press the OFFER button again.
Pressing this also switches the current studio to the LSO bus.
Mixers, Source Selectors & Switchers - RB- OA3
ACCEPT
This mode is used to accept the transmission path. To do this, press
the ACCEPT button once the offer has been made. Once the studio has
accepted, this switches the OFFER, DELAY, DUMP and SUSTAIN functions to
that studio.
SUSTAIN
This mode is used to switch to a sustaining service, for example, a PC
automation system, which conventionally wouldn’t be in its own studio and
would therefore need external control to take transmission back from it.
Think of it as a studio which has no Offer and Accept controls of its own,
but which can still be put to and from transmission by the other studios.
The sustain studio is Studio 3 by default and this cannot be changed. Once
the sustain function is activated, the transmission path switches instantly to
Studio 3 and is automatically offered back to all studios. To enter SUSTAIN
mode, press the OFFER button to enter offer mode then hold the ACCEPT
button for three seconds. DELAY and DUMP modes are inactive in SUSTAIN.
The SUSTAIN mode has two phases:
SUSTAIN ACTIVE
In this phase, studio 3 is transmitting and the offer is made to all studios.
The offer button flashes in all studios to let the controllers know that
the sustain mode is active. To retrieve the control, a studio must press
the flashing OFFER button. SUSTAIN mode then enters phase 2, SUSTAIN
ARMED.
6
DELAY/DUMP
These functions are used to control a profanity delay. To use these functions
route the transmission to the delay unit control input and setup the delay
unit accordingly. The output is then taken from the delay unit. The unit has
both a normally closed and normally open relay trigger. When the DELAY
or DUMP button is pressed, a half second pulse triggers the specific relay
which will either connect to, or break, the connection with a Common
signal (supplied from the delay unit).
EMERGENCY
In the multiple unit cases there is an EMERGENCY mode. This mode is
activated with the SLAVE units to alert the user that communication with
the MASTER has broken down. In this mode, all LEDS associated with the
unit will start flashing (except the POWER LED).
While the unit is in this mode it will not respond to any commands. Once
the unit re-establishes a connection with the MASTER, the unit will return
to the position it was in prior to the disconnection, if the MASTER is
unchanged, or it will update if the MASTER has changed. As an extra safety
feature, if the STUDIO EXPANSION SLAVE loses communication while
studio 4 or 5 is transmitting, the MASTER will lock all ability to change
transmission studio until contact is re-established. If the MASTER loses
power or all communication paths, all SLAVES will display emergency mode.
In addition if any SLAVE loses power it will automatically reboot into the
correct state.
SUSTAIN ARMED
In this phase, a studio is ready to take control. The OFFER button is
constantly lit in the studio that triggered this phase and the ACCEPT will
flash in both the arming studio and Studio 3. In the other studios, all the
buttons will be inactive and the LEDS will all be off.
The arming studio can now accept the transmission path by pressing the
ACCEPT button. If the arming studio wants to return the unit to SUSTAIN
ACTIVE phase, the OFFER button should be pressed.

Profanity Delay Control
A profanity delay unit can be attached and controlled to the unit via this
interface. The control is achieved using a relay. Each relay has a common
input pin and two possible output pins (open or closed). The relay can
then be configured to route the applicable voltage to it’s output pins. For
example for an active low triggered input, 0V would be connected to the
relevant Common pin and the profanity delay input pin would be connected
to the Normally Open pin of the relay.
Serial Ports
There are two parallel serial ports on the back of each unit to enable the
connection of multiple RB-OA3 units. These use standard RJ-45 connectors.

The RB-OA3 has been designed for installation in a central technical area
with cabling to custom panels, or selection switches, in each studio. If you
don’t have any custom switch panels available, you can use an RB-OA3R in
each studio. The RB-OA3R is a 1U rack mount switch unit for use in each
studio that needs to be connected to the STUDIO 1-3 CONTROL connectors
on an RB-OA3. It takes it’s power from the RB-OA3 unit so needs no power
supply itself.

9 RB-MM1 Mix Minus Generator
Introduction
Fig 9-1: RB-MM1 Front Panel.
Whenever programming originates from outside of the studio, or if
listeners/viewers are calling up a phone-in using telephone hybrids or
codecs, mix-minus feeds are required. Most telephone lines incur delays
which prohibit off-air monitoring, because the caller, or remote talent,
would hear their own voice in delay which is very disconcerting. The
solution is to feed a mix back to the caller minus his or her own voice. Some
mixing desks do not have a dedicated telco channel to generate a cleanfeed, or mix minus, so the RB-MM1 can be used.
The RB-MM1 is a unit for generating a suitable mix to send to a telephone
hybrid or codec. A stereo output is taken from a mixer, together with a post
fader output from the mono telephone fader on the mixer. The caller audio
is removed from the station output so that it can be sent to the telephone
line via the hybrid.
Analogue audio inputs and outputs are via Neutrik XLR connectors.
The output level to the TBU can be adjusted using a rear panel pre-set
potentiometer. To control the cancellation null, 2 multi-turn potentiometers
are provided, one for the LF null and the other for the full-band null.
Additionally, a band pass filter can be switched in and out, via a rear panel
switch, to condition the signal for the telephone hybrid. To use the RB-MM1
unit with full-band ISDN codecs, the band pass filter can be switched out.
For stereo codecs, or conference calls, multiple RB-MM1 units can be used.
A red LED indicates when power to the RB-MM1 is on.

Stereo Inputs From Mixer Main Output
These inputs should contain the main mixer output which will be a feed of
the programme plus the audio that you want to remove by the mix-minus
unit. Ideally, the input should be presented at 0dB. The XLR 3 pin sockets
used for the left and right channel inputs are electronically balanced

Input From Mixer Telephone Fader
This mono input should contain the audio that needs to
be removed by the RB-MM1, usually from the telephone/
telco fader of a mixing console. Ideally, the input should
be presented at 0dB. The XLR 3 pin socket used for the
mono channel input is electronically balanced and has an

Output Null Adjustments (LF and Full-Band)
The 2 x null preset potentiometers are used to adjust the
null between the input from the telephone fader and the
main stereo input. The telephone input is made anti-phase
and used to cancel out that signal in the main stereo signal.
So, the nulls adjust the level of anti-phase signal required to
achieve the best mix-minus null.
Band Pass Filter Switch
The band pass filter, when in the ON position, is used
to limit the audio bandwidth of the output to the TBU
between 200Hz and 4kHz. When using the RB-MM1 in full
bandwidth equipment, e.g. for ISDN audio codecs, set this
switch to the OFF position.

Talkback & Communications - RB- MM1
Output Level Adjustment
The TBU output gain can be adjusted from -15dB to +12dB, ref 0dBu by
using the LEVEL preset potentiometer.
Operation of the RB-MM1
Before you receive your RB-MM1, it is calibrated at Sonifex by using two
signals of equivalent amplitude and frequency. In some cases it may require
recalibrating for use on a mixer to match the properties of that mixer. In
order to do this make the following connections:
1. Mixer left output to the RB-MM1 left input .
2. Mixer right output to the RB-MM1 right input.
3. Mixer post fade output from the relevant input channel (usually telco) to
the RB-MM1 telephone fader input.
Then apply a signal to the input channel and raise the fader to its maximum
level. To get the best results connect a level meter to the “Output to TBU”
connector. Alternatively monitor the output acoustically and tune by ear.
Then adjust the NULL potentiometer until the output is as low as possible, if
there is still some low frequency output adjust the LF NULL as well. The null
available on this product is >40dB at 1kHz.

The RB-MTV1 contribution voiceover monitor is a 1U rack-mount designed
to be used in voice-over booths, news booths, commentary locations, for
continuity announcements and for any other similar applications where
voice needs to be added to programme content and then monitored.
Programme feeds, auxiliary feeds and a talkback feed can be taken in and
monitored.
The RB-MTV1 has a microphone input, two main mono outputs, two
external stereo monitoring inputs plus a 4-wire. It has a mono microphone
input on XLR with switched coarse gain and variable fine gain control using
a multi-turn preset potentiometer to give an overall gain range from +20dB
to +80dB. There is also a switched LF rumble filter, switched +48V phantom
power and switched level limiting control. A rear-panel multi-turn preset
potentiometer allows adjustment of the threshold at which the limiter
begins to operate, from -8dBu to +26dBu. There is an indication of the
limiter activity using a blue LED and the microphone level is monitored by
a simple 5 LED meter. The meter can be configured to either show the MIC
signal activity in normal operation, i.e. when TALK is pressed the meter is
off, or the meters can permanently show the MIC activity even when the
TALK button is on or the MIC button is off.
There is a mono balanced TALKBACK input on XLR. There are two balanced
XLR stereo inputs, CUE and programme (PGM) each with a 10dB input gain
switch to facilitate the use of unbalanced sources such as from PC audio
cards, domestic CD players, etc.
Each of these inputs, MIC, TALKBACK, CUE and PGM can be mixed and
monitored in the front and rear headphone outputs with individual volume
controls. Which of the inputs is presented to the headphone outputs can
be configured using two banks of DIPswitches on the underside of the unit,
65

Talkback & Communications - RB- MTV1
one bank for audio that is heard in the left ear piece and one bank for audio
monitored in the right ear piece. For example, the left and right PGM inputs
can be sent to the right ear-piece and all other signals to the left ear-piece,
or the TALK signal could be sent to the right ear-piece and all other signals
to both ear-pieces. In this way, you can configure the unit for your particular
application on installation. If a presenter doesn’t like to hear themselves
in their headphones when using the TALK button, there is also a DIPswitch
option to mute the mic signal to the headphones.
There are two mono balanced outputs. The processed microphone signal
is fed to the two outputs when the electronically latching front panel MIC
button is active - the button illuminates when active.
The two main outputs can be independently switched to be at ‘Line’ or
‘Mic’ level outputs using rear panel push switches. Setting the output to
a microphone level allows the unit to be inserted into the microphone
channel of a mixer. There is an option to permanently enable the MIC

The limit level control is a multi-turn preset potentiometer to set the
maximum output level when the limiter is enabled. The level can be set
between -8dBu and +26dBu and as standard is set at +8dBu.
Mic Input Gain Control
This is a multi-turn preset potentiometer to adjust the gain of the
microphone input. The gain ranges from +20dB to +80dB when used with
DIPSwitch 1 on the rear panel.
Microphone Input
The microphone input is an electronically balanced mono mic level input
that is routed directly to the MIC headphone level control on the front
panel, to adjust the mix into the headphones. The microphone audio
appears on the two main outputs whenever the electronically latching
MIC button has been pressed and illuminated. The microphone signal is
switchable on to the ‘lazy’ talkback output by pressing the TALK button. The
XLR socket has the following connections:
Pin 1: Screen.
Pin 2: Phase.
Pin 3: Non-phase.

Options are available to add phantom power at +48V to the microphone
input (DIPSwitch 3 ON), switch a low frequency rumble filter in (DIPSwitch
3 OFF) and to add an additional 20dB of gain to the microphone input: The
microphone gain range is adjustable from +20dB to +80dB and this is done
as +20dB to +60dB via the MIC GAIN rotary potentiometer with DIPSwitch 1
OFF, or +40dB to +80dB via rotary potentiometer with DIPSwitch 1 ON.
Switching Options
TALK button - On pressing the TALK button, set DIPSwitch 4 to ON to mute
the microphone signal to the headphones, for the situation where you are
using talkback and don’t want to hear your own voice in the headphones.
MIC button - The MIC button can be permanently latched, i.e. always on,
70
by setting DIPSwitch 5 to ON. In this mode, the microphone can not be
switched off or remotely switched off, but all other operation is normal, for
example, pressing the TALK button mutes the mirophone to the Outputs
1 and 2. This is useful in situations where you need to leave the unit
unattended and want to ensure that the microphone is always on, e.g. for
covert operations, or where the operator may be unfamiliar with the unit’s
operation.
Metering Option
The meter can be made to permanently show the level of the MIC input.
With DIPSwitch 6 set to OFF, the metering is disabled whilst the TALK button
is pressed. With DIPSwitch 6 set to ON, the metering permanently shows
the microphone input level.
Remote Option
The Remote Mic switch input (Pin 1 of the Remotes) can be controlled by a
latching or momentary switch. With DIPSwitch 7 OFF, a momentary switch
will operate it. With DIPSwitch 7 ON, the remote switch needs to be a
latching type.
Output Option
By setting DIPSwitch 8 to ON, the CUE stereo input can be mono mixed to
Outputs 1 and 2.
DIP Switch Settings (On The Underside Of The Unit) For Headphone
Channel Mix Options
The DIPSwitches on the underside of the unit can be used to define which
of the sources (MIC, TALKBACK, PGM and CUE) are sent to which side of
the headphone output (left or right).. There are two sets of switches; the
ones on the left represent the left earpiece of the headphones, the right
switches represent the right earpiece. Setting the DIPSwitch to ON enables
the selected source to the selected earpiece.

11 RB-IPE IP Extender for GPIO & Analogue Control Signals
Introduction
Fig 11-1: RB-IPE Front Panel
The RB-IPE is a 1U rack-mount unit designed to provide remote control of
GPIO and analogue control voltages over an Ethernet network. Configured
using a built-in web server, two units can control each other across an
Ethernet network, or a single unit can be controlled via Ethernet commands
and the web server interface. The unit can be used in any position where
you need to remotely acquire GPIO signals or remotely control equipment,
for example controlling equipment at unmanned posts, outstations or
transmitter sites.
The unit connectivity is incredibly flexible, allowing a wide range of input
signals for both the digital and analogue ports. This flexibility continues
with many configuration options; each port can be configured to behave
independently and the webserver allows you to monitor and adjust the
status / configuration of all ports on any networked unit.
Each unit has 16 general purpose inputs on 8 RJ45 connectors, consisting of
8 opto-isolated current sink inputs and 8 pull to ground protected inputs.
There are 16 general purpose outputs on 8 RJ45 connectors consisting of 8
isolated relay changeover contacts and 8 opto-isolated contacts. The status
of each GPIO is indicated by LEDs associated with each RJ45 socket.
On another 8 RJ45 connectors are the analogue control voltage inputs and
outputs. Each input has 3 hardware fixed voltage ranges where 3 separate
pins allow for input ranges of 0 – 3.3V, 0 – 5V or 0 – 12V. The 8 analogue
outputs offer the same 3 ranges on a single pin controlled by software.
All output ports can be controlled by the inputs of a remote unit, Ethernet
commands (see page 78) or directly from the webserver.
This allows any tallies and control signals, together with potentiometer
movements to be sent across a network, e.g. for remote alarm points, to
trigger failure alarms at a transmitter site and to control remote equipment.
For example when two units are connected together at different sites
(remote and local), the pair can be configured such that, when a local
general purpose input state changes the unit sends the new status to the
remote unit where a corresponding general purpose output is operated.
Similarly the local analogue control voltage inputs can be monitored and
forwarded to corresponding output ports of the remote unit.
The signal routing and distribution options are numerous.
For the GPIO ports:
• Each local input port can be assigned to control any remote output port.
• A single local input can be used to control multiple remote outputs.
• Local general outputs can be configured to respond to a threshold
voltage on a local analogue input
• Local outputs can be status locked and the logic can be inverted.
73
11
Talkback & Communications - RB- IPE
For the analogue control voltage ports:
• Each local input port can be assigned to control any remote output port.
• A single local input can be used to control multiple remote outputs
• A local input port can be used to control any number of local general
outputs with respect to a preset threshold voltage (e.g. for sending an
instruction to a GPO when a volume knob is turned too high).
• Each local output can be locked off, or pinned to a programmable preset
voltage level.
• Any local input voltage range can be mapped to any remote output
voltage range.
• A local linear input can be converted to a logarithmic output voltage
scale.
The configuration of each unit is stored locally and in the event of a power
cycle the unit will continue to operate as previously configured. You can
also store a start-up state for each GPO and a start-up voltage for each
analogue output allowing more reliable recovery of external connected
equipment from a power-fail condition.
The web server in the RB-IPE can be configured with a static IP address or
by using DHCP.
The RB-IPE is powered from a universal mains input between 85-264V AC at
47-63Hz.

Reset Button
After completing a firmware update or in the unlikely event that the RB-IPE
becomes unresponsive, press the reset button to reboot the unit (see Fig
2-1 for location).
The reset button can also be used to perform a factory reset, to bring the
unit back to original defaults, including network settings:
• Notice that when the reset button is pressed, each of the three front
LEDs light up in sequence.
• You need to press the reset button four times in total:
• Press it once to start the sequence.
• The second press should be made whilst the first (Connected) LED is lit
up.
• The third press should be made when the second (GPIO) LED is lit.
• The fourth press should be made when the third (Analogue) LED is lit.
• Upon the fourth reboot the unit will load factory default settings and all
three LEDs will flash to signal that the factory reset has been performed.
Rear Panel
There are no physical controls other than the reset button. The LEDs on the
two banks of GPIO ports show the current state of each port (illuminated
when active) and are numbered accordingly. The green Ethernet LED shows
link status/activity, and the amber LED indicates Speed (On = 100Mbps, Off
= 10 Mbps).

Ethernet Interface Commands and Responses
Most of the commands follow the same structure: a 3 letter command
followed by a colon, followed by one or more parameters delimited with a
comma, and terminated by Carriage Return with optional Line Feed. A Line
Feed character may be sent but it will be ignored by the RB-IPE. Commands
are case sensitive.
Outputs 1 – 8 have 3 off software controlled voltage ranges.
Responses are CR & LF terminated and all commands may be issued by UDP
or TCP/IP to port 31781 on the RB-IPE.
Note: The maximum current per output is 5mA @ 12V / 30mA @ 5V /
25mA @ 3.3V.
Following are the commands and the expected responses. Because there
are quite a few commands, they are grouped into relevant subsections:

IP Address = 192.168.0.100
Net Mask = 255.255.255.0
Gateway = 192.168.0.1
Otherwise, DHCP can be turned on / off using the NOP: command. The
Static Network settings can be modified using the NET: command.
Communication Sequencing:
For tracking / debugging purposes the IPE will accept a 5 character
identifier in front of any command it receives. This identifier must be in the
form:
NNNN# - where N = any character, and # is the delimiter between the
identifier and the command itself.
An example Command might be:
30CB#GPI:? - which could be the 12491st request for GPI Statuses or a
single request from a source identified as “30CB”.
The IPE will automatically copy this identifier (if in the correct format) to its

Fig 12-1: RB-TGHDX Front Panel
The RB-TGHD is a 1U rack-mount, 8 channel audio tone generator that
provides line identification for multi-channel audio systems, including
5.1 and 7.1 surround sound typically used in high definition television
broadcasts. By using a range of widely accepted industry standard tone
sequences, channel identification and associated levels can be determined
easily. Correct channel configuration in fold-down mixes can also be
highlighted when a broadcaster needs to mix several audio channels into a
stereo feed.
The RB-TGHD caters for 2, 4, 6 and 8 channel configurations and all of
the available audio tone sequences for each channel configuration can
be cycled through automatically, or selected manually, and a loop mode
allows patterns of tones to be repeated. A bank of 4 pushbuttons on
the front panel sets these options and the associated LEDs indicate the
current setting. A set of 8 LEDs on the front panel indicate which channel is
currently outputting audio.
The audio line-up level can be adjusted from 0dBu to +24dBu in 1dBu steps
and the digital sample rate can be set from 32 kHz to 192 kHz in both 16
bit and 24 bit formats. As standard, the RB-TGHD has TTL wordclock input
synchronisation. This can optionally be upgraded to a digital audio input or
an analogue or digital video input.
The RB-TGHD is available in two variations. Both models provide 8 channels
of audio in both analogue and digital formats. The balanced analogue
outputs are via 3 pin XLR connectors. The RB-TGHDX has balanced AES/EBU
digital outputs via 3 pin XLR connectors. The RB-TGHDB has unbalanced
digital outputs via BNC connectors. When using the internally generated
master clock, Channel Status information is generated and encoded on
the digital output channels with the appropriate bits for sample rate and
sample width set accordingly.
The serial port allows the RB-TGHD to be connected to a PC running SCi the Sonifex Software Control Interface. This allows full control of the unit
and the ability to generate a user defined audio tone sequence of up to
60 seconds in duration. In addition, a remote port on the rear provides a
simple interface to control the unit and several outputs to indicate which
tone sequence is active.

Sequence Mode Button & LEDs
This button selects either auto or manual
sequence mode. Auto mode cycles through
all sequences that are enabled by the
current channel setting (see Table 1-1).
Manual mode allows individual sequences
that are enabled by the current channel
setting to be selected. The sequence mode
button illuminates red when it is pressed.
The default setting is auto mode.
All of the RB-TGHD’s user controls and
configuration settings are located on the
front panel. Each push button has a range
of LEDs associated with it that illuminate to
show the current selection.
The LED on the left of the front panel is
normally red to indicate that power is
present on the unit.
Channel Active LEDs
These 8 LEDs provide a visual indication of
which channels are currently outputting
audio tones.
Channels Button & LEDs
This button selects the number of channels
that output audio, from 2, 4, 6 or 8. If a
sequence is active when this setting is
changed, and the sequence is valid for
the new channel setting, the sequence
will automatically restart. Otherwise, the
sequence will stop. The channel button
illuminates red when it is pressed. The
default setting is 8 channels.

Force Bootloader Mode – Bank 2 DIP Switch 8
This mode should only be used if the unit fails to respond after a firmware
upgrade attempt. With this DIP switch On, and all others in Bank 2 set to
Off, the RB-TGHD will force the Bootloader to run and allow initiation of
an update under any circumstances. Once an update has completed, this
switch should be returned to the Off position.
Reset Button
In the unlikely event that the RB-TGHD unit fails to respond, press the
recessed reset button via the small hole in the front panel.
Sequence Details
There are 6 pre-defined sequences on the RB-TGHD. Each channel that is
used in a sequence is assigned a tone frequency and an audio level. These
values remain constant while the sequence is active. When a channel
is un-muted, the corresponding LED on the front panel is illuminated.
All channels are muted at the start of a sequence. An additional ‘user’
sequence can be programmed into the unit via the SCi software.

Serial Interface Commands & Responses Protocol
SCH:n
Sonifex SCi remote control software handles all communication with the
RB-TGHD via a convenient graphical user interface. However, this protocol
is provided for those users who wish to develop their own remote control
applications.
SER:
For more information on how to install and operate the SCi software, please
see page 97.
SRQ:
Serial Data Format
Most of the commands follow the same structure: a 3 letter command
followed by a colon, followed by a parameter (if any) and terminated by
Carriage Return with optional Line Feed. A Line Feed character may be sent
but it will be ignored by the RB-TGHD. Commands are not case sensitive.
Responses will be CR & LF terminated.
After the Tone Generator has been powered-up, an initialisation string is
sent “Sonifex
RB-TGHD” followed by the version number of the currently installed
firmware.
Following are the commands and the expected responses:

control can all be accessed from this main panel. The channel active LEDs
across the top of the screen show the state of each channel. This screen
also shows additional information on the current DIPSwitch settings and
details of the type of external sync board that is fitted, if any. Please note
that SCi is continuously updated so the images may appear differently to
those shown.
User Sequence Programming
This screen allows the user sequence to be easily edited. The sequence
consists of up to 8 independently configured channels with a maximum
of 50 steps on each channel. The bottom of the screen shows a graphical
representation of the current sequence with the coloured regions showing
when the channel will be un-muted.
Fig 12-13: SCi Main Control Screen
Fig 12-14: SCi User Sequence Screen
To change a setting or start the currently selected sequence, simply press
the associated button.
The Sequence Load button reads the current user sequence that is currently
stored in the RB-TGHD memory and displays the details, overwriting any
user sequence that is currently being edited. When the user sequence
screen is selected, the current user sequence is automatically loaded.
The Sequence Save button performs a check on the user sequence data
before writing the details to the RB-TGHD. Once a valid sequence has been
written, it will be available for selection until it is overwritten or deleted.
98
Talkback & Communications - RB-TGHDB & RB-TGHDX
The Sequence Delete button clears the user sequence currently stored in
the RB-TGHD.
The Sequence Duration edit sets the total running time for the sequence in
milliseconds. The maximum duration is 60000 ms (60 seconds).
The Channel selector selects a channel to edit. As the channel is changed,
the relevant data will be displayed.
12
example, if there are 5 steps and the step selector is set to 3, a new step
will be inserted at position 3 and the current steps at position 3, 4 and 5 will
be moved to 4, 5 and 6 respectively.
The Step Delete button removes the currently selected step.
Firmware Updates
The Misc screen shows the Update Firmware option.
The Channel Frequency edit sets the tone frequency for the selected
channel. The Frequency value must be between 20Hz and 16000Hz.
The Channel Amplitude selector sets the audio amplitude for the selected
channel between 0 dBFS and -48 dBFS.
The Channel Copy button allows the settings on one channel to be
reproduced on a different channel. First select the channel to copy using
the Channel selector, then press the Copy button. Now select a channel to
copy to by clicking on one of the channel names in the lower half of the
screen.
The Channel clear button deletes all the settings for the selected channel.
The Step selector selects a sequence step to edit. Each step is a period
where the channel is un-muted.
The Step Position edit sets the point at which the channel un-mutes for the
selected step. This value is an offset from the start of the sequence and is
measured in milliseconds. The Position value must be between 0 ms and
59950 ms.
The Step Duration edit sets the length of the un-mute period for the
selected step in milliseconds.
The Step Add button adds a new step to the selected channel. A maximum
of 50 steps can be assigned to each channel.
The Step Insert button inserts a new step at the currently selected step. For
Fig 12-15: SCi Misc Screen
Occasionally, it may be necessary to upgrade the firmware on the RB-TGHD
to add new functionality and fix software bugs. New firmware updates will
be made available from time to time on the Sonifex website. Visit www.
sonifex.co.uk for details.
It is vital that neither the serial connection nor mains power to the RBTGHD should be interrupted during the update process. If this should
99
12
Talkback & Communications - RB-TGHDB & RB-TGHDX
happen, or the update is unsuccessful for any other reason, the RB-TGHD
will not operate normally and will instead enter a protected Bootloader
mode. In this mode, the unit has a limited command set and will await a
successful retry of the update process.
Installing the Optional Sync Boards
There are 4 sync boards which can be used to synchronise the outputs of
the RB-TGHD. The RB-SYW is installed in the unit as standard, the others are
options.
Should the firmware update appear to succeed but the unit not behave as
expected, the update may be repeated either via the DWN: command (if
the unit will respond to commands) or, in extreme circumstances, by setting
DIP switch number 8 in Bank 2 to ON. All other DIPSwitches in Bank 2 must
be off. This action will force the Bootloader to run and allow initiation of
an update under any circumstances. After completion of the update, the
switch should be returned to the OFF position.
RB-SYW
The Audio Word Clock sync board will accept a distributed clock running at
the desired sample frequency between 32 kHz and 192 kHz. The signal can
be differential or single ended TTL level.
To upgrade the firmware on the connected RB-TGHD, click on the Update
Firmware button and select the required firmware file. Once the firmware
upgrade has started, all of the LEDs on the front panel of the RB-TGHD will
turn off except for the sync LED which indicates the status of the upgrade
process as shown:
Sync LED State
Status Of Firmware Upgrade
Flashing Amber
Receiving firmware file
Constant Amber
Programming new firmware
Constant Green
New firmware installation successful
Constant Red
New firmware installation failed – try again
Table 12-9: Firmware Upgrade Status LED
The new firmware is transferred, and then the current firmware is erased
before programming the update. Please note: Firmware files can take
several minutes to transfer to the RB-TGHD at lower baud rates. To speed
up the process, select a higher baud rate prior to transferring the new
firmware.
100
RB-SYE
The AES/EBU sync board will accept a digital audio input signal with a
sample frequency between 32 kHz and 192 kHz. When using the RB-SYE
sync board, the Channel Status information that is encoded in the input
data signal is copied to all digital output channels on the RB-TGHD.
RB-SYA
The Analogue video sync board will accept a composite signal of NTSC
(525), PAL (625) & SECAM (625) signals covered by SMPTE-170-M (NTSC)
and ITU-R BT.470-6 (PAL & SECAM). The recovered sample rate is 48 kHz.
RB-SYD
The Digital video sync board will accept 270Mbps SD-SDI and HD-SDI signals
covered by SMPTE-259-M-C (SD) and SMPTE-292M (HD). The recovered
sample rate is 48 kHz.
Opening the RB-TGHD
Warning: The power must be switched off at the supply or the power lead
must be disconnected before attempting to open the unit. Removal of the
cover can expose dangerous voltages.
1. Remove the 4 screws in the corners of the rear panel.
2. Remove the 4 screws on the top and bottom panels which hold the rear
panel in place (2 on the top and 2 on the bottom).
3. Remove the screw in the centre of the front panel.
Talkback & Communications - RB-TGHDB & RB-TGHDX
4. Slide the rear panel and main PCB backwards out of the metal chassis
giving you internal access.
5. Remove the rubber grommet/bung on the rear panel which covers the
hole for the sync connector.
6. Remove the 2 screws from the bottom of the sync card pillars and,
making sure to keep the plastic washers in place at the bottom of the
pillars, fit the 20 way pin header into the 20 way connector on the RBTGHD motherboard.
7. Underneath the board, insert the 2 screws to fix the board in place.
To put the unit back together, slide the PCB back into the chassis and refit
the screws in reverse order.
