About Encore 1
Welcome to the Encore family!
Encore is a modern, high-quality range of products designed around a common hardware and software platform.
The Encore family includes:
§ Audio processors
§ RDS coders
§ Stereo generators
§ Rebroadcast receivers
§ Audio backup devices
§ Modulation analysers
§ …and is growing all the time!
Encore uses high-quality components, robust hardware and an innovative user interface, which provides many benefits to broadcast technology users.
Modules and components are common to all products in the range – meaning ease of service and minimal need to stock replacement parts.
For example, if you have an RDS coder, a modulation monitor and a backup audio device, the same power supply, the same audio board and the same DSP board is used in each one!
The rear panel is the same on every product. This means wiring can be standardised, installation is simple and easy.
Front panels are consistent across the range – with OLED screens, LED displays, a scroll knob and a few soft-keys, every products is easy to operate.
Encore has been designed to be very simple and intuitive to set up and operate – everything is where you’d expect it to be and is easy to understand and use. Once you’ve used one Encore product you can use them all!
The user interface is designed around the concept of ‘System’ and ‘Presets’ menus, where the System menu is the same for every product and contains all the audio level settings, the versatile and exclusive ‘Events and Alarms’ section as well the communications, monitoring and telemetry system.
1 - 2
All product-specific settings are contained within the ‘Presets’ menu – providing an automobile radio -like interface which works just as well for profiles in an RDS encoder as it does for settings in an audio processor, a modulation monitor or rebroadcast receiver.
The web remote control interface is common across all products, as is the API and the internal language, so it’s simple to interface the whole Encore range of products with your common monitoring and telemetry system.
Every Encore product includes, as standard:
§ Backup audio
§ Events and Triggers –based Telemetry
§ Comprehensive communication section
§ Analogue and Digital audio interfaces
§ Ethernet, USB and RS232 connectivity
§ Interactive Web remote system
§ SNMP and TelNet support
A common hardware and software family of products, which are easy to set up, easy to use, easy to maintain and easy to service.
Innovation, usability, quality, and confidence are what you get from Encore!

The RBRX Encore 2
The award winning RBRX1 was widely regarded as the best rebroadcast receiver on the market, so improving on it has been no easy task. The RBRX Encore offers all the features of the RBRX1 - and then some.
This premium rebroadcast receiver has two tuner cards as standard and a whole host of new industry first features, including but not limited to dual tuner diversity blending using advanced polarisation multi-path cancelling techniques. There's still the multi-band L-R adaptive stereo noise reduction pioneered by the RBRX1.
The user has full control of dozens of audio and RF settings, including audio and IF bandwidths, de-emphasis and blending for stereo, HF and ultrasonic noise. Control of blending levels and attack & release times is also possible.
For re-transmission applications, the RBRX Encore adds DSP enhanced MPX outputs that reconstruct a clean peak level and bandwidth limited waveform, eliminating worries about studio transmitter link overshoots. We had amazing feedback from users about the RBRX1's sound quality. You'll be pleased to know the RBRX Encore is even better, thanks to its enhanced DSP audio limiter and stereo generator, both with continued industry leading levels of backend aliasing distortion.
§ 2 DSP tuners now offer full diversity reception from both antenna inputs.
§ Increased RDS encoder capabilities with more monitor and decode facilities if
you wish to use it as an analyser or monitor.
§ Enhanced DSP audio limiter & stereo generator for even clearer sound quality.
§ Unique ‘FMSI’ signal processing to recover good quality stereo reception from
noisy or weak signals.

NAVIGATING
The Encore products have an intuitive interface based around a pushable scroll knob, surrounded by a ring of LEDs, with a series of buttons. Some products have three buttons, some five and some six.
The buttons can be ‘soft keys’, and perform various functions denoted by icons shown adjacent to them in the displays, or may be function-specific - in which case the buttons are illuminated with the following symbols:
ONLINE
OFFLINE
DECODE
ENCODE
INPUT 1 INPUT 2
Audio is passing through the unit and is being processed.
Input is connected to output and audio is not being processed.
The unit is operating as a stereo generator, or
encoder, producing a composite (MPX) output
signal from the analog or digital inputs!
The unit is operating as a stereo decoder,
producing discrete left and right, analog and
digital outputs from a composite signal input.!
Switches the unit to tuner 1 or MPX input 1.!
Switches the unit to tuner 2 or MPX input 2.!
6-2
The icons that can be shown against the softkeys are as follows:
If the ‘scroll screen left’ or ‘right’ icons are displayed, this indicates that there are additional screens available. Pressing these buttons slides the displays to and from these other screens.
Back’ will move back up one step in a menu tree.
Undo’ and ‘redo’ are typically used in an audio processor to perform an
‘A/B comparison’ between two presets, or between a modified and an unmodified preset.
The ‘headphone’ button, when pressed, will cause the icon to flash indicating that the headphone level may be directly adjusted by rotating the scroll knob
(rather than having to enter the System | Audio menu as described in Section 8).
This mode will time out after 5 seconds of inactivity, or when the button is pressed again.
The ‘delete text’ and ‘accept text’ buttons are used when the virtual ‘qwerty’ keyboard is being employed to add or modify text, perhaps to name a preset or to enter other alpha-numeric strings such as email addresses etc.
While navigating the menus, if an ‘info’ help-text is available for that parameter, the ‘i’ symbol will illuminate next to a softkey. Pressing this softkey will show the
information; pressing it again (or pressing ‘back’) will dismiss the info.
The Encore’s high-quality OLED displays show various levels and parameters, plus allow selection and editing of the various settings throughout the unit.
The menu system is navigated by rotating the knob to highlight an item and pushing it to open a submenu, or to select the parameter for editing.
While in a submenu, pressing the ‘back’ softkey will return to the parent menu.
6-3
EDITING A PARAMETER
To edit a parameter, navigate to it in the menu using the knob - square brackets [ … ] will surround the currently highlighted parameter. Press the knob to select the parameter, then rotate the knob to change it.
Changes happen immediately as you turn the knob; press the knob again to keep the change; alternatively press the ‘back’ softkey to revert without changing.
The parameter setting will be shown on the OLED screen, numerically and with a progress bar, as shown below:
EDITING A TEXT FIELD
When editing a text field, such as the system name or a preset name, a ‘qwerty’ keyboard will be shown on the OLED display.
Highlight the letter to be used by turning the knob and press to select. To delete a letter, use the softkey adjacent to the ‘X’ icon .
To switch to a numerical keyboard, select the ‘123’ button with the scroll knob and press to select.
To accept and save the new text, press the softkey indicated by the ‘check' icon .

7.1 QUICK SETUP
To get you started, here is a description of the unit’s configuration with some common uses:
CONFIGURING AS A MONITOR RECEIVER
1. From the home screen, highlight ‘presets’ and push the knob to enter the presets submenu.
2. Preset 1 will be highlighted, along with the frequency that tuner 1 is currently set to. Press the knob to enter the preset 1 submenu.
3. Scroll to highlight ‘tuner 1 frequency’, press the knob to select, then turn it to enter the desired frequency. Press the knob to save this, then press ‘back’ three times to return to the home screen.
4. Enter ‘system’, ‘audio i/o’. Highlight ‘outputs’ and press the knob to open the submenu.
5. If you’re using the analog outputs, change ‘an output source’ to ‘tuner 1’; if using the digital output, change ‘dig output source’ to ‘tuner 1’. You may also need to change the ‘digital sample rate’ to that the equipment to which is connected requires.
6. If you’d also like to monitor via headphones, set ‘headphone source’ to ‘tuner 1 audio’.
7. Connect a receive antenna to the rear-panel ‘FM1 IN’ connector.
8. Connect the analog, or digital outputs to a suitable amplifier/speakers or mixing desk etc.
Note: The diagram shows only one antenna connected; The RBRX Encore has two antenna inputs and two separate tuners – later in this manual we will learn the benefits and applications of this.
Listen with pleasure!
7 - 3
CONFIGURING AS A REBROADCAST RECEIVER
…with the received composite audio feeding the transmitter.
1. Carry out actions 1 through 3 in Section 7.1 above, to set tuner 1 to the frequency of the transmission you wish to rebroadcast.
2. From the home screen, enter the ‘system’ menu and navigate to the ‘audio i/o’ submenu.
3. Enter the ‘outputs’ submenu.
4. Set the ‘mpx 1 source’ to ‘mpx generator’.
5. Set ‘mpx out level’ to your desired level.
6. Navigate to ‘MPX generator’, enter that menu and set the source to ‘tuner 1 audio’.
8. Set the pilot level to your desired level, probably 9%.
9. Press ‘back’ three times to return to the home screen.
Note: You could set ‘mpx 1 source’ to ‘tuner 1 mpx’ – then the received mpx signal would pass through the unit unmolested; however you will not then be able to feel the benefit of the complex ‘FMSI’ dsp-based signal processing, which can recover very good stereo audio from a poor or noisy receive signal.
This is because, in the RBRX Encore, the ‘FMSI’ dsp signal processing is carried out in the demodulated audio domain. We recommend you take advantage of this powerful feature.
Connect the rear-panel ‘mpx1 output’ socket to your transmitter, and connect a receive antenna to the rear panel ‘FM 1 IN’ connector.
Of course, if you’re using the RBRX Encore as a rebroadcast receiver, you can still configure it as a monitor at the same time. You could also configure the audio and/or headphone outputs to carry audio from tuner 2, which could be on another frequency, including the frequency you’re transmitting, so you can hear your transmitted audio!
7 - 4
The two tuners in the RBRX Encore are fully independent and can be set up on two different frequencies (unless you’re using the ‘Diversity’ feature).
This gives you the opportunity of having a main and a backup frequency for rebroadcast.
To do this, connect an antenna pointing at your main site to tuner 1, and set that tuner to the main frequency.
Connect another antenna to tuner 2, pointing at your backup site, and tuned to that site’s frequency.
Set the audio routing as above, but in addition, navigate to System | Events, and set up an event the trigger of which is RSSI 1 – the signal strength being received by Tuner 1.
Set the condition to be ‘less than’, and the value to be one below which you consider that signal to be too poor to use – say 30dBuV.
Set On Delay to maybe 5s, leave Load Preset at ‘none’, and set Revert to ‘delay’. Set this delay to 5s.
In Set/Change, select ‘mpx gen src’, and set the To field to ‘tuner 2 audio’.
Now, when the signal being received by Tuner 1 drops below 30dBuV (such as when that transmitter has gone off air) the RBRX Encore will wait 5 seconds, then switch to relaying the signal being received on Tuner 2.
When the transmitter Tuner 1 is listening for returns, the RBRX will wait 5 seconds and then return to relaying the main transmitter.
We suggest using delays of around 5 seconds to preclude false switching because of noise bursts or if the transmitter takes time to stabilise when it returns to air.
In the same Events section, you could also set up the RBRX Encore to email you when the main transmitter’s signal fails.
More anon.

7 - 5
CONFIGURING AS A STEREO GENERATOR
1. Go to ‘system ‘, ‘audio i/o’, ‘outputs’, and set ‘mpx 1 source’ to ‘mpx generator’.
2. In ‘system’, ‘mpx generator’, set source to ‘analog audio’ or ‘digital audio’ depending on how you’re feeding the unit.
3. Scroll to, and set your desired pilot level.
If you wish to add or modify RDS information to your composite stereo signal, please then do the following:
4. From the home screen, navigate to ‘presets’, ‘preset 1’, ‘rds’… and set the RDS parameters as you need.
5. Then back in ‘mpx generator’, set the RDS level to the percentage you need, probably 2-4%.
And that’s it.
A more detailed description of the configuration of the RBRX Encore follows:
!
THE SYSTEM MENU
This menu contains all the fundamental unit configuration settings, and should be the first place you go after taking the Encore out of its box!
These settings are peculiar to the installation, perhaps the transmitter site itself, as opposed to the following ‘Presets’ section (Section 9) which are particular to the exact usage and model of the unit.
Power the unit up, and from the home screen, highlight and press the ‘system’ button:
You’ll now see a list of submenus:
Audio i/o: Contains all audio input and output settings, as well as output routing selections. (Not present in all Encore products)
MPX generator: Settings for the mpx (‘composite’) generator. (Not present in all Encore products)
Events: A comprehensive events/alarms/scheduling system.
Time: Manually setting the unit time and date, or automatically setting
this via ntp.
Users: Set up admin user and standard users.
Communication: A sub menu containing settings for identity, ethernet,
email, web remote, snmp, telnet, logging and RS232.
About: Unit information and power supply status.
Note: Certain menu items will be different or not present in some products, as appropriate to their features.
Let’s take some time to discuss the contents of each of these menus:
8.1 AUDIO I/O
(Certain menu items are omitted in some products in the Encore range).
Within this there are two submenus – ‘inputs’ and ‘outputs’.
‘Inputs’ allows you to set the operating level of the unit when referenced to the rest of
your installation. For both analog and digital reference level, please set these to your maximum normal operating level.
For example, if you will be feeding analog audio into the unit that may reach but never
exceed +12dBu, set the ‘analog ref level’ to +12. (For PPM users, PPM4=+4, PPM5=+8,
PPM6=+12).
Similarly, if your digital levels may meet but not exceed -10dBFS, set ‘dig ref level’ to -10.
‘Outputs’ allows you to set output levels from each physical output, and choose what source feeds those outputs.
The sections of this submenu are:
An (analog) output source: none analog audio digital audio tuner 1 audio tuner 2 audio test tone (a 1kHz sine wave) diversity
Analog output level: -18dBu to +24dBu
Dig (digital) output source: none analog audio digital audio tuner 1 audio tuner 2 audio test tone diversity
Dig output level: -20dBFS to 0dBFS
Dig output sample rate: 48kHz 96kHz 192kHz
MPX 1 source: none mpx in 1* tuner 2 mpx* mpx generator pilot tone rds
MPX 1 out level: 0dBu to +12dBu**
MPX 2 source: none mpx in 1* tuner 1 mpx* tuner 2 mpx* mpx generator pilot tone rds
MPX 2 out level: 0dBu to +12dBu**
Headphones source: none analog audio digital audio tuner 1 audio tuner 2 audio test tone diversity
Headphone level: 0 to 100%
For convenience, the headphone source and headphone level settings are duplicated directly under the ‘audio i/o’ menu.
* Note that if ‘tuner 1(or 2) mpx’, or ‘mpx in 1’ is selected as the source for an mpx
output, the received signal merely passes through the unit, unaffected by the ‘fmsi’
signal processing (please see section 9 of this manual).
** The mpx output level adjustments only affect the output of the internal mpx generator. If the mpx (1 or 2) output source is set to ‘tuner 1 (or 2) mpx’, the output level is fixed at +6dBu.
8.2 MPX GENERATOR
(Not present in all Encore products)
This menu controls the on-board stereo generator (‘MPX’ meaning multiplex, sometimes known as ‘composite’).
The stereo generator includes a composite clipper. With a drive level of 0dB, this has no effect; above that it will become active and clip the MPX signal. The clipper contains RDS/SCA protection filters, also there is a pilot protection filter option.
The audio clipper protects the MPX generator from peak excursions and overshoots in the source audio. It is distortion-cancelling and anti-aliased.
Furthermore, there is an ‘overshoot compensator’ which handles any overshoots from
the main clipper, and restricts the audio bandwidth to 15kHz.
The MPX generator menu contains the following parameters:
Source: none analog audio digital audio tuner 1 audio tuner 2 audio diversity test tone Preemphasis: 50uS, 75uS, off.
Pilot level: 0 to 12% in 0.1% increments
RDS level: 0 to 5% in 0.1% increments
Audio clip drive 0 to 12
O-sh compensate drv -3 to 9 (overshoot compensation drive)
Comp (composite) clipper drive: -0.5 to 2
Pilot protection no / yes
8.3 EVENTS
This is a very comprehensive monitoring, events and alarms section. It allows changes to be made to the configuration of the Encore unit resulting from external sources via the Events and Triggers port, or from conditions detected from incoming signals – be they via the tuners or the audio inputs.
It is really a telemetry system in itself. As events can be triggered from external sources, you can use it to monitor other equipment in your facility, even door-open sensors, intruder alarms, in fact anything that can pull one of the four input pins to 0v.
The system is designed in a very intuitive, conversational way. “When this happens, for this long, do these things. Then when it’s stopped for this long, do that.”
In the ‘events’ menu, the first sub-menu is ‘GPO pin config’. In this section, with the ‘mode’ parameter, you can determine what each of the four GPO pins do:
1. Switch as an event action (see later);
2. Track tuner 1 signal strength;
3. Track tuner 2 signal strength;
4. Track analog input level;
5. Track digital input level.
6. Track unit temperature.
With option 1, the pin is a ‘digital’ output (i.e. either ‘on’ or ‘off’). With options 2 through
6, the pins act in an analog manner, outputting 0 – 5v which will track whatever signal you have selected.
The other option available in this menu is ‘polarity’ – where you can set each pin to output either active Hi-Z (high impedance) or active low (i.e. connected to 0v).
The Events and Triggers port pinouts are:
Next is the list of the 8 available events, each of which can perform a variety of actions when triggered.
Please highlight and select one of the events.
To set up an event:
1. For now, leave the ‘active’ setting ‘off’.
2. Select from the list what you want to ‘trigger’ the event; the choices are tuner signal strengths, tuner audio levels, analog and digital inputs and outputs, unit temperature and the status of the GPI pins.
3. Then select what ‘condition’ should cause the trigger – more than, less than or in some cases equal to or not equal to.
4. Next, set the ‘value’ – the range here varies according to the trigger type.
5. Next is the time to wait after triggering before the event is activated (for example, wait for 15 seconds of silence before activating the event).
6. ‘revert’ determines what happens when the trigger condition ends – does the unit go back to its previous condition, and if it does, is it immediate or delayed?
7. Next you can set this revert delay.
The next parameters set what actions the event causes. You can set it to do any or all of the following:
load a different preset; change tuner frequencies; change various output sources; switch one of the GPO pins; send an email; send an snmp trap message.
Note that if you select ‘load preset’ as an action, the ‘revert’ function is greyed out and
not available. This is because a change of preset can involve a change of frequency of
both tuners, so in this case there’s no way the Encore can know when or if the event trigger has ended.
When you’re happy with the event setup, return to the top of the event menu, and switch it to ‘active’.
Exit from the ‘events’ menu by repeatedly pressing ‘back’ until you reach the home
screen.
8.4 TIME
This menu allows you to set the unit’s time and date, or if it has network access to an ntp
server, to use that.
The following parameters can be accessed:
uptime: A display of the time, in hours, minutes and seconds that the Encore has been powered up.
time: Allows manual setting of date and time.
ntp: off / on (whether to use ntp or not)
update now: ‘run’ – pressing this forces an immediate update of system time via the ntp server.
host: the ntp hostname, e.g pool.ntp.org or an IP address.
period: How often an ntp time update occurs – every 1hr, 12hrs or 24hrs.
8.5 USERS
This menu allows you to define parameters for people who will have access to the Encore unit, and who will be able to log in via the web remote.
There are four users available:
admin A ‘power-user’ who is able to edit/change settings as well as view all screens;
user 1, 2, 3 These users can be limited to either merely viewing settings and screens, or controlling them in the same way the admin user can. However, a non-admin user with ‘control’ privilege cannot add or change any other user’s details.
Within the users menu, you are able (if you’re an admin) to set the users’ password, their
email addresses and their privileges.
[In an imminent firmware release, ‘security’ will be implemented which will utilise these
settings more comprehensively].
8.6 COMMUNICATION
This menu contains the following submenus:
Identity: Allows a unit name, site number and lat/long (‘GPS position’) to be set. This is useful when managing multiple units via the web interface, and when receiving emails from the ‘events’ section, so it’s obvious where the email came from.
Ethernet: Allows you to set the following parameters, relevant to the IP network the Encore is connected to:
DHCP: ‘on’ if your network has a DHCP server from which the Encore
will be able to derive network parameters automatically; set to
‘no’ to define these settings manually.
DNS: ‘on’ to use the dns server derived above, or ‘off’ to manually enter a DNS server.
IP: Manually enter he unit’s IP number.
Subnet mask: Manually enter the unit’s subnet mask appropriate to your network.
Gateway: Manually enter the gateway IP number (usually the IP number of your router).
DNS 1: Manually define one DNS server IP number.
DNS 2: Manually define an alternate DNS server.
MAC: A display of the unit’s mac address
Link: Shows ‘up’ if the unit’s ethernet connectivity is working, ‘down’ if not.
Email: Allows you to set up the email communication of the
Encore:
Sender: the email address of the Encore, e.g encore- 01@stationname.com
Mail method: ‘BW’ to allow the unit to send emails via the BW Broadcast monitoring system; ‘SMTP’ if you wish to send the emails via your own SMTP server;
(if ‘SMTP’ is selected, further settings will appear allowing you to specify the name of this server, it’s authentication method and if necessary the SMTP password).
Test: This submenu allows you to send a test email to one of the users (previously defined in 7.1.5 ‘Users’ in this manual).
Web remote: Here you can turn on or off access to the Encore
by the ‘Encore web remote’ software, and to define the
port that this web remote will use – default is the common http port 80.
SNMP: Settings for using Simple Network Management Protocol, to allow the Encore to communicate with other telemetry and monitoring systems.
The SNMP ‘MIB’ file is accessible when the unit has an ethernet connection, by navigating to http://[unit IP]/Encore.mib
Telnet: Set Telnet access on or off, and define the port.
Logging: Sets up a UDP connection to an external logging server, and/or log to file o via a serial connection.
RS232: Enable/disable the rear-panel RS232 (serial) connector, and sets the baudrate to be used.
8.7 ABOUT
A display of unit details, serial number, hardware and software versions etc. This information may be requested by a BW Broadcast support technician if you need live assistance. The OLED ‘sleep’ timeout is also set here.
RESTART AND FACTORY RESET
There is also a ‘restart’ and a ‘reset to defaults’ command in this menu. Beware – ‘reset to defaults’ will remove any settings you have modified in Presets, and everything you
have entered in System.
…which includes the Ethernet settings – so this isn’t a good thing to do if you’re connected remotely, as you may lose IP connectivity.
STATUS
This submenu shows values of current hardware parameters: PSU voltage; PSU current; PSU power; fan voltage; fan state; temperature; plus fan speed control – which should be left set to ‘auto’ unless otherwise advised by a BW Broadcast support technician.
9 - 1
Presets Configuration 9
THE ‘PRESETS’ MENU
This menu can be thought of the same way as a set of presets on a car radio or standard hi-fi tuner. These settings are particular to the stations or frequencies being received.
From the home screen, highlight the ‘presets’ button, and press the knob.
You will be presented with the following screen:
This shows the list of presets – those prefixed with the letter F are factory presets, the prefix U indicates a user preset location.
The rest of the preset locations will become visible if you scroll down the list.
To the left of each preset name is the ‘status block’.
The current preset is shown highlighted – if you scroll away from this, the status block to the left of the preset name remains filled to indicate that this is the preset that is currently loaded.
If this block shows the letter A, this indicates that the preset has been selected by an ‘action’ from the ‘events’ section of the RBRX Encore (see section 8 in this manual).
If the block shows the letter S, the preset has been selected by a ‘schedule’ event.
If a preset has been edited but not saved, an asterisk * is shown in this block. If multiple statuses are active, the priority is: A, S, *, .
In addition, in this screen, softkey 5 shows the i symbol. Pressing this will display extra information about the highlighted preset, such as tuner 2 frequency, RDS station name (if available) and date/time the preset was created and last used.
9 - 2
The factory presets cannot be overwritten, however they may be used as good starting points for you to create your own presets, which can then be saved in one of the user preset locations.
The factory presets are:
F1: Default: Contains a group of settings determined to provide good performance in strong receive signal conditions. F2: Soft: Settings which apply light processing designed to enhance the receive signal under less than perfect conditions. F3: Hard: Settings which apply much more signal processing, to enhance and restore extremely poor signals. F4: Measure: Signal processing is bypassed, to allow measurements of the incoming signal with it unaffected by any processing within the RBRX
Encore.
9.1 LOADING A PRESET
To load a preset, scroll to it using the knob, when your desired preset is highlighted, press softkey 6 – which you may have noticed is now displaying a ‘tick’ icon.
Or you can scroll to the preset and press the knob – this will load the preset and enter preset edit mode.
If you have a user preset loaded, and you then load one of the factory presets, the receive frequency and deemphasis setting is not altered. The RBRX Encore will in this case apply the rest of the processing and refinements contained within that factory preset.
!
9 - 3
9.2 EDITING A PRESET
To edit a preset, scroll to it and press the knob. This action will load the preset too – as the configuration is actually edited ‘live’.
As soon as a preset is modified, an asterisk * appears in the status block, and softkey 6 displays the undo icon.
An asterisk will also be shown in the top line of the edit screens as soon as any modification is made, to remind you that the preset is in a modified state.
Pressing the ‘undo’ button will revert the preset (and therefore the live state of the RBRX
Encore) to its unmodified and saved state. Once pressed, the ‘redo’ symbol is shown
against softkey 6. Guess what happens if you press it!
If you attempt to exit the preset edit menu and load another preset before saving your changes, a warning dialog box will appear, informing you that if you continue, your changes will be lost, and asking if you wish to continue, or go back to save your modified preset.
Once you press the knob to enter the preset edit mode, the first submenu shows:
Tuner 1 frequency: Allows quick-setting of tuner 1 receive frequency.
Tuner 2 frequency: Allows quick-setting of tuner 2 receive frequency.
Preset name: Selecting this brings up a ‘qwerty’ keyboard, so that an optional friendly name can be appended to the default preset name, which is U1 98.0, for example. The first part of the preset name is always the preset number followed by the frequency of tuner 1.
Save to: Allows the settings contained within the current preset to be saved back to itself (not if it’s a factory preset) or to any other user preset slot.
Note: If you try to save to a preset slot other than the one you’ve modified, a pop-up will warn you that you are about to overwrite the contents of that preset, and asking you if you’re OK with that.
Copy t1 to t2: Causes the immediate copy off all tuner 1 settings to tuner 2.
This is useful if you have set up all your settings in tuner 1 and wish to duplicate them in the other – either for use in ‘diversity’ (see 8.4 in this manual) or if the second tuner is going to be used to receive a second frequency as a backup (obviously you’d only have to change the tuner’s frequency then).
Diversity: Sub-menu which contains ‘diversity active yes/no switch and the ability to adjust diversity weightings. Please see section 8.4, below, for a detailed explanation of this powerful feature.
9 - 4
9.3 TUNER 1 AND TUNER 2
The contents of the ‘tuner 1’ and ‘tuner 2’ menus are identical:
Frequency: Another place to set the tuner’s frequency.
Deemphasis: Set de-emphasis to suit your region, 50 or 75µS. For test and
measurement purposes, it’s also possible to select ‘off’.
Note: the following advanced functions allow access deep under the hood to the many complex and advanced processing parameters that makes the RBRX Encore unique in its performance as a rebroadcast receiver.
These parameters have been set up in the factory presets F1 to F4 by our design team, and do not necessarily need to be adjusted by the user.
We include them here for use by power users who wish to delve deep, and create extremely complex and specific presets.
Channel EQ: An adaptive filter to improve reception when multipath interference is being encountered. On/Off.
Mpath suppression: Reduced audibility of distortion caused by multipath interference. On/off.
Noise blanker: Detects and supresses noise pulses. On/off.
Audio trim: Fine adjust of the tuner’s audio level to account for
discrepancies in the deviation level of the received signal.
IF filter: Settings for the IF bandwidth of the tuner. Entering this submenu will allow you to manually adjust the bandwidth, or set it to ‘auto’.
Stereo blend: A system for the simple handling of stereo reception in weak signal conditions. Does not recover stereo signal, merely modifies stereo separation to mask the effects of the poor signal. Parameters are:
Time: Defines the weak signal handling for the level detector and noise/multipath detectors.
Mod: Enables modulation dependency and sets sensitivity.
Level: Sets level sensitivity and enables slow and fast timing.
Noise: Sets noise sensitivity and timing.
Multipath: Sets multipath sensitivity and timing.
Min: Optionally allows a minimum amount of stereo separation reduction under good signal conditions.
Max mode: Disables stereo blend function, for test and measurement purposes.
9 - 5
St improvement: A submenu containing controls for a complex, proprietary DSP- processing system (FM Stereo Improvement, ‘FMSI’) which improves stereo performance in less than perfect signal conditions.
You can select ‘hi blend’ or ‘FMSI’. The ‘hi blend’ setting provides settings for the traditional method of FM weak signal handling, in which the HF component of the left and right audio channels is ‘blended’ together to reduce noise, or hiss, which becomes prevalent in the stereo domain. The parameters for hi blend are:
Time: Defines the weak signal handling response times for the level detector and noise and multipath detectors. Fast and slow response times are available for dual timer functionality, with enable options for the level, noise and multipath parameters.
Level: Sets the level sensitivity and enables slow and fast timing.
Noise: sets the noise sensitivity and enables slow and fast timing.
Multipath: as above, for multipath.
Max: sets the maximum amount of blend to occur in very poor signal conditions.
Min: optionally defines the minimum amount of blend, as realised in good signal conditions.
The ‘FMSI’ alternative introduces an advanced, multiband processing system for recovering good audio quality and stereo performance from weak or noisy signals. The parameters are:
Blend time: Defines the weak signal handling response times.
Blend gain: Defines the weak signal handling sensitivity for the four available audio bands.
Blend bias: Defines how the system operates with good quality reception but low modulation levels.
The performance of the Stereo Improvement can be monitored on two screens (one for each tuner), which are available on the left OLED display:
!
9 - 6
Meters on this screen are:
IFBW: IF bandwidth. USN: Ultra-Sonic Noise – sometimes known as MPX noise. RSSI: Signal Strength. MPTH: Multipath.
..in the ‘blend’ section of the screen:
SM: Soft Mute. HC: High Cut. SB: Stereo Blend. HB: High Blend.
..in the ‘fmsi’ section of the screen:
LO: Low band.
2.2k: The 2.2kHz band. 5k: The 5kHz band. HI: High band.
We recommend for normal use, FMSI is selected. Indeed, our factory presets ‘f1 default’ and ‘f3 hard’ employ this to good effect.
Please note that since Stereo Improvement (FMSI) operates in the demodulated audio domain, its benefits are not available if you select ‘tuner mpx’ as a source for one of the mpx outputs. Even if you are using an mpx output to feed your transmitter, we recommend selecting ‘mpx generator’ as the source for the MPX output, and ‘tuner 1(or
2) audio’ as the MPX generator source (see section 7.1).
Softmute: Settings to control how the signal will mute if the signal deteriorates.
High cut: Timing and quality sensitivity settings for a low pass filter, which can help
with weak signal handling.
Low cut: A high pass filter, useful for removing subsonic noise.

9.4 RDS
This submenu allows you to set the RDS/RBDS parameters of the MPX/composite output signals.
It’s very clever, in that it allows you, if you wish, to use some of the RDS parameters being received, and others locally generated.
This means that you could, for example, set a slightly different PS (station name) for the rebroadcasted signal, so you can tell by looking at the radio’s display which particular transmitter you’re tuned to, or to alter the AF (alternative frequency) list to make it more efficient by not including frequencies not audible within that transmitter’s service area – all the time maintaining the rest of the original RDS data.
To set all locally-generated RDS info, please set ‘source’ to ‘local’;
To set all received RDS info, set to ‘rec’d’ (the tuner which is supplying this data is the one set as the source of the MPX generator [see section 7.2]);
To set a mixture of the two, please set this parameter to ‘custom’, then enter the custom data you wish to use in the rest of the RDS parameters.
Please note: If the MPX generator is receiving it’s audio from either the analog or digital inputs (described in section 7.2), obviously there is no received RDS data. In this case, the
RBRX Encore will derive the RDS data solely from the ‘local’ settings.
So if you are using the analog or digital inputs as a backup source, it’s important that all the ‘local’ parameters are set, otherwise when you’re on backup audio there won’t be any RDS!
This does mean that you could be very clever, and slightly alter your station’s PS (station name) in the ‘local’ PS setting, maybe add a *, so that you have an indication on your radio that the station has gone to backup audio!
RDS SETTINGS
Encoding: rds/rbds (rbds for the US, rds for rest of world)

9.5 DIVERSITY
!
This powerful feature enhances the performance of the RBRX Encore, adding single frequency diversity.
In some circumstances, it is desirable to provide the receiver with two RF inputs carrying the same signal, and allow the receiver to dynamically and intelligently ‘choose’ which signal is the best one to use.
Situations where this may be beneficial include particularly distant reception, where atmospheric conditions may cause reception to deteriorate because of ‘ducting’ – causing fade-outs, situations where there is a tidal water path between transmitter and receiver, and sites where local topography or building clutter can cause polarisation changes and increase multipath distortion.
Such problems can be ameliorated by the installation of two receive antennas, perhaps one high up a tower and the other low down, or one vertically polarised and the other horizontal.
The RBRX Encore utilises powerful digital signal processing to analyse the signals being received by both tuners, and seamlessly switches between them to provide the best possible useable signal.
This decision is based on an average of certain criteria including signal strength, multipath, USN (ultrasonic noise, sometimes called ‘MPX noise’) over a rolling 1-second window; tuners are switched by crossfading from one to the other, this action taking 10mS.
The weightings of these criteria are preset, but can be adjusted if you require by entering the ‘weighting’ submenu under ‘diversity’.
If you wish to use the diversity feature, please switch ‘diversity’ to ‘on’, in the menu at presets | preset x (see section 8.0), and select ‘diversity’ in the source selections for the
9 - 10
mpx generator source and the audio output sources, as appropriate, as described in Section 7 of this manual.
Note that once ‘diversity’ is switched on, the frequency of tuner 2 will be automatically locked to that of tuner 1. A pop-up warning will appear if this action will change the frequency of tuner 2.
We recommend in this case that you use the ‘copy t1 to t2’ function (described in 8.2 above) initially, to ensure both tuners are setup identically; you can of course subsequently modify the parameters if you wish.
The performance of the diversity system can also be monitored on the tuner status display, by means of a sliding bar, which represents the ‘quality’ of the signal being received by the tuners.
The tuner with the best quality reception will be the one being routed to the ‘diversity’ output; on this display, the ‘active’ tuner and its frequency is highlighted.
This concludes the description of the ‘preset’ menu.
Take a few moments rest, you’ve earned it!
