UNPACKING AND INSPECTION

Upon receipt, the equipment should be inspected for possible shipping damages. If such are found or suspected, notify the carrier at once and contact DEVA Broadcast Ltd. The original shipping carton box and packing materials should be kept for possible reuse, in case of return for Warranty repair, for example. Shipping damages as a result of improper packing for return may invalidate the Warranty!
IT IS VERY IMPORTANT that the “Product Registration Card” on page 68 included in the
Manual be completed accurately and returned. This will assure coverage of the terms of the Warranty and it will provide a means of trace in case of lost or stolen equipment. In addition, the user will automatically receive SERVICE OR MODIFICATION INSTRUCTIONS from DEVA Broadcast Ltd.

RADIO FREQUENCY INTERFERENCE (RFI)

Although we have made provision for DB6000-STC installation in the immediate proximity of broadcast transmitters, please do practice some care using the unit near abnormally high RF elds.

Mounting

RACK REQUIREMENTS

The DB6000-STC mounts in a standard 19-inch equipment rack and requires only 1¾ inches
(1U) of vertical rack space. In order the painted nish around the mounting holes to be protected,
the use of plastic washers is recommended.

HEAT DISSIPATION

Having very low electricity consumption, the DB6000-STC itself generates negligible heat. The unit is intended for operation within an ambient temperature range, extending from freezing
to 120°F/50°C. But because adjacent, less efcient equipment may radiate substantial heat, be
sure that the equipment rack is adequately ventilated to keep its internal temperature below the
specied maximum ambient.

AC Mains Power

FUSE HOLDER

The fuse holder is placed inside the unit, next to the voltage selector. Apply downward pressure and pull the cap outward to access the 5mm mains fuse. The reverse process will release the cap.

MAINS VOLTAGE SELECTOR

Before connecting the AC Power, make sure that the internal Power Switch and the fuse rating are in accordance with the mains supply at your location.
DB6000-STC Power Supply Factory Settings are:
- 100 - 240 VAC
- 1 Amp Fuse
CAUTION: Permanent damage will result if improper AC supply voltage is applied to
DB6000-STC device. Your warranty does not cover damages caused by applying improper supply voltage, or use of an improper fuse.

POWER CORD

The detachable IEC-type power cord is supplied with the unit. The individual cord conductors may be color-coded in either of two ways:
1) In accordance with US standards:
BLACK = AC “HOT”
WHITE = AC NEUTRAL
GREEN = EARTH GROUND
2) To European CEE standards:
BROWN = AC “HOT” BLUE = AC NEUTRAL GREEN/YELLOW = EARTH GROUND

GROUND LOOPS

Because the unbalanced MPX OUTPUTS of the DB6000-STC are chassis-ground-referenced, a mains frequency or RF ground loop could be formed between the input or output cable shield grounds and the AC power cord ground. A ‘ground-lifting’ AC adapter may well remedy such a situation, although the chassis somehow must be returned to earth ground for safety. Generally, being screwed-down in the equipment rack will satisfy the safety requirement.

DB6000-STC Location

The best location for DB6000-STC is as near as possible to the transmitter, so that its stereo
encoder output can be linked to the transmitter through a circuit path. If this conguration is
not possible, the DB6000-STC’s AES3 digital audio output can be fed through an all-digital, uncompressed path to the transmitter exciter.
The usage of left and right analog audio outputs is recommended in the situations when the stereo encoder and exciter are under the jurisdiction of an independent transmission authority, and the programming agency’s jurisdiction ends at the interface between the audio facility and the link connecting the audio facility to the transmitter. (The link might be telephone / post lines, analog microwave radio, or various types of digital paths.)

Source Material Quality

The DB6000-STC is designed to achieve perfect sound quality, regardless of the source material. Though, it is very important that the source audio to be as clean as possible, as upon processing the poor-quality source material will cause distortion and unpleasant audio defects.

Basic Setup/Connection Example

REFERENCING ANALOG AND DIGITAL INPUTS LEVEL

In order for the proper work of DB6000-STC to be guaranteed, and due to the variability of the signal levels, the right reference levels of the digital and analog inputs should be set.
The process of aligning the signal levels to the needed boundaries is called referencing inputs.
The Reference level is specied depending on the intended source device and typical program
material fed at the input.
The Reference level (Ref. level) represents the amplitude of the input signal applied at DB6000-STC’s analog input, which after ADC (analog-to-digital converter) will be considered as 0dBFS. The set Ref. Level value must be conformable to all operating conditions, as the level of the analog program material at the input should not be higher than that. Setting Reference level that is unnecessarily high may affect the dynamic range of the input and to increase the noise level.
Depending on the dynamics of the audio program, fed at the input, we recommend the Ref. Level set to have headroom from 4dBu to 12dBu above the audio program. For example:
Audio program level at the input: 6dBu
Headroom: 10dBu
Ref. Level to be set: 16dBu = 6dBu + 10dBu
In case of sudden amplitude transients or unanticipated loud events in the program, the material reserve guarantees that the signal will not be clipped.
For the analog inputs the reference level is set in the Input> Analog Inputs Reference Levels> Main Level and Analog Inputs Reference Levels> Aux Level. With default values as follows:
- Main Level - 12.0 dBu;
- Aux Level - 12.0 dBu.
The reference level that could be set is between -8dBu to +24dBu.
As a general rule, when the Ref. level is properly selected, DB6000-STC’s front panel AGC indicator should vary from +6/9 during continuous operation.
If AGC indicator is constantly at its lowest value, the set Ref. Level should be increased. If the maximum possible value of 24dBu is met, the level of the audio program fed at DB6000-STC’s analog input should be reduced.
If the AGC indicator is constantly at its highest value, the Ref. Level should be reduced. If the minimum value of -8dBu is met, the level of the audio program at the input increased.
DB6000-STC digital inputs have pre-dened reference level of 0dBFS, but in order for the signal
to be reduced or increased to values guaranteeing the best performance of the audio processor, user
dened values of the main and auxiliary digital inputs could be set. The preferred levels are set in
the Input> Digital Inputs Reference Levels> Main Level and Digital Inputs Reference Levels> Aux Level. With default values as follows:
- Main Level - 0.0 dBu;
- Aux Level - 0.0 dBu.
Please have in mind that when applying these settings, if need be, the signal received from
the corresponding digital input can be amplied. The excessive increase, however, can lead to
unwanted signal clipping.
IT IS VERY IMPORTANT the signal fed at the any input of DB6000-STC not to exceed the
specied reference level, otherwise it will cause clipping, distortion and unpleasant audio defects.

REFERENCING ANALOG AND DIGITAL OUTPUTS LEVEL

These settings dene the value of 0 dBFS when converted to dBu. Similarly to the input Ref.
Level, the output Ref. Level determines the amplitude of the respective output, which corresponds to 0dBFS. The value is set depending on the level requirements of the device connected to DB6000-STC’s digital output. Having the proper Ref. level set at the output of the audio processor, guarantees that the signal amplitude at the input of the subsequently connected device will be within the required optimal range. As a general rule, the amplitude of any of DB6000-STC’s outputs cannot exceed the Ref. Level set for this output.
For the analog output, the Ref. Level could be set in the range of -12dBu to +24dBu with
0.5dB step. For the MPX outputs, the Ref. Level is set in the range of -18dBu to +18dBu with
0.1dB step.
For the digital output, the Ref. Level is set in the range of -20dBFS to 0dBFS with 0.5dB step.
The preferred output values could be applied via the:
Outputs> Analog Out Level,
Outputs> Digital Out Level,
Outputs> MPX 1 Out Level,
Outputs> MPX 2 Out Level.

ANALOG CONNECTION WITH DEVA SMARTGEN 6.0

The DB6000-STC has built in basic RDS/RBDS Encoder, in case additional RDS/RBDS Encoder is added, a “Loop Through” and “Side-chain” connection with the audio processor can be made.

Side-chain

Side-chain – the RDS& MPX output is sent to the Input SCA input, while to provide the RDS encoder with a Sync signal for the 19 kHz pilot tone, the entire program can be taken out via MPX OUT-2. Make sure that you will not send the same signal as the one generated by the RDS encoder to the MPX OUT-2.
IMPORTANT RECOMMENDATION: It is mandatory that the cable used for connection
between DB6000-STC’s MPX output, and the MPX input of the transmitter be as short as possible. This will prevent any face distortion.

Loop through

The output of the DB6000-STC is wired directly to the PILOT/MPX IN of the SmartGen 6.0. The output of the RDS encoder will be connected to the composite/MPX input of the FM transmitter. This connection is not recommended, because the composite signal/MPX passes through the RDS encoder, and the transmission of the program will be interrupted in case of failure of the RDS encoder. If you are using SmartGen 6.0, such failure will be prevented, as the DEVA technology includes a Hardware Bypass between RDS & MPX OUT and MPX Input of the FM Transmitter. The RDS Subcarrier phase will be locked to the MPX stereo FM Signal on the outside.

How can a preset be made?

IT IS RECOMMENDED the presets to be created prior to the installation of the DB6000-STC
in the broadcasting chain. Otherwise, any drastic changes of the audio quality and enhancements will be audible for the listeners.
The procedure is quite simple. Below you will nd a step-by-step description of the process:
1. Choose an empty preset that you would like to use for basis of the new one;
2. Modify the parameters that you think would improve the enhancement of your signal and will make your station’s sound unique;
3. Once you are satised with the result, go back to the Presets page. You will notice that in front of the currently selected preset, a ‘pen symbol’ indicating that some changes are being made will appear. In order to save the changes select one of the user presets and press the [Save] button. The following message box will appear:
Specify the preset name and press [OK].
4. A window requiring verication will appear. Conrm the changes by pressing the [OK] button;
5. The newly created preset will be automatically chosen as ‘active preset’.

Preset Lock

As many of the stations prefer to use the services of qualied personnel when creating the
perfect preset, the DB6000-STC supports the function the newly created preset to be locked. The preset can be locked upon its export. The following options are available:
Key – the preset will be locked with a key known only by the creator. Thus, only users familiar with it would be able to import it into devices different than the one used for the purposes of creation;
Serial – you can specify the serial number of the device on which the preset can be used. Only the unit with this serial number will be able to import this preset. If the preset should be used only by the current device, press [This device] button and the serial number will be automatically assigned.
Depending on your preferences, both, one or none of the above explained options can be used.

In order for a user preset to be exported the following procedure should be completed:
1. Select the preset to be exported via the [Export] button. The following message box will appear:
2. If the preset is to be lock – complete the needed information. If not, press the [OK] button to continue;
3. Conrm to save the le on your computer.

Presets Import

1. Press the [Import] button on the desired position. The following message box will appear:
2. Browse the le to be imported and specify Key if it has been locked. Then press [OK] to continue;
3. The newly uploaded preset will be automatically chosen as ‘active preset’.
If the preset has been protected by password, or has been assigned to a specic device (via the
Serial function) the following message will appear:

General – Several types of Main Audio Sources could be set – Main Analog, AUX Analog,
Main Digital, AUX Digital, MP3 Player and IP Audio Client.
When setting the Input Gain level, have in mind that the applied settings have inuence over the processed signal after the Input bargraph, thus meaning that the bargraph values will not change when altering the value of the Input gain.
Test Generator – There are several modes of operation– Left+Right, Left–Right, Left and
Right. Set the Level and the Frequency of the signal at which the generator should process.
The ‘Test Generator’ will generate a test signal with which the DB6000-STC and the equipment connected to its outputs could be examined.

IP Audio Client – Set Decoder from the drop-down menu, and URL of the stream server.
• Decoder (+ Sample rate) – Select decoder and sample rate. It can be set to Auto or set manually to preferred decoder and sample rate. In Auto Mode, the DB6000-STC will adjust decoder and sample rate, using stream supplied information. For PCM (uncompressed) sample rate can be 32, 44.1 or 48 kHz. For MPEG1 the sample rate is determined automatically from the stream.
• Pre-buffer – The minimum amount of time in which the unit will prebuffer before playing starts in order for problems with the connection to be prevented.
MP3 Audio Player – The Playback Order can be changed from here. The following options
are available: A-Z, Z-A, Shufe, Playlist, and Shufed Playlist. Information on the used and available SD card storage respectively, could also be found in this section. [Repeat] and [Next] button to navigate through the playlist if need be, are also available.
MP3 Files Upload via FTP – Through the use of a standard FTP client, you have the opportunity
to update the backup content at will via any PC. The supported format is .m3u. An important
requirement for the MP3 Player conguration is that all MP3 les should be stored in a folder
named Audio (no sub-folders are allowed). The folder should be located in the root of the SD Card.
The playlist le must be named playlist.m3u.
For information on how the connection between the DB6000-STC and an FTP Client should be
congured, please refer to “APPENDIX B” on page 70.
IMPORTANT NOTE: Use a plain text editor to create a le named playlist.m3u.
Analog/Digital Inputs – Set the peak levels of the analog/digital inputs. This corresponds to
the absolute maximum level that the input could receive i.e. the user guarantees that the fed level
will not exceed the one specied. The specied level in dBu corresponds to 0 dBFS. Levels can
be set for each input. For the analog input, 2 input level ranges are available, +12 or +24 dBu, set with jumpers directly on the sound processing board.
Fallback – DB6000-STC supports up to 3 fallback sources. In order for a source to be used a
backup should be specied. The following options are available - Main Analog, AUX Analog, Main Digital, AUX Digital, IP Audio Client, MP3 Player. The conditions when backup source
has to be used should also be specied (Loss Threshold and Loss Timeout). This is how the backup works - upon loss of the Main source, the device will switch to Backup 1. If Backup 1 fails also, the DB6000-STC will switch to Backup 2 and etc. The DB6000-STC does not return to the previous source if it is restored. When the Main source signal is restored the device will automatically switch back to it.
Pre-emphasis – set the preferred pre-emphasis type - Flat, 50μs for Europe and 75μs for USA,
and Drive.

DB6000-STC has four separate sections of ‘parametric’ equalization, which can be attributed to any combination of Freq (frequency), Q Factor (bandwidth) and Gain (amplitude). These may be assigned to any combination of low frequency EQ, mid-band EQ and top-end EQ chores. However, all four sections are identical and each of them may be programmed in frequency between 50 Hz and 15 kHz. (15 000 Hz) Of course, there is an option the equalizer to be enabled or disabled.
Within each section of parametric equalization, the Freq, Q Factor and Gain are individually adjustable. The sliders of the EQ Section panel select the frequency range, and identical ranges are available in each equalizer section.
Freq – Parametric band center frequency;
Q Factor – Applied lter quality - width of the parametric band;
Gain – gain of the parametric band.

As each EQ slider is moved, the resultant change in response, both in that EQ section and its overall contribution, is shown on the graph, placed on the bottom of the tab. It displays the individual frequency response of each of the four equalizer bands and the summary frequency
response of the entire EQ section, including pre-emphasis. Each band has a pre-dened color
visible on the bottom right of the graph.
[Undo] erases the last change applied to the settings reverting them to their previous state. Please note that not only the last applied setting will be undone, all settings that are not saved will be disregarded. The opposite of [Undo] is [Redo].

To disable the processing and evaluate and the difference between the processed and raw signal, there is an incorporated [Bypass] option in the form of a button. When the [Bypass] option is enabled, the entire process will be stopped.
AGC Is intended to normalize the difference in the audio levels fed at the input. The AGC
effectively reduces the volume if the signal is strong and raises it when it is weaker. Input Gate setting is the level below which the ‘gate’ closes and the AGC gain gradually returns to 0dB (its resting value). Gating prevents increase in the very low-level background sounds during pauses in the program. The threshold level is referenced to the AGC corrected signal, and recommended settings are typically around -20dB (the default value). A Gated Flag will appear next to the LED
indicator in the top section of the WEB interface, if the signal at the input is below the specied. The Rate and Max Boost are also user-dened settings.
Clipper detects and removes (almost) any distortion that is audible by the human ears. This
results in an extremely clean sound. A brief explanation on the clipping controls can be found below:
Attack – Controls the attack rate of the clipper. It represents the time needed for a response to
increase in the input level.
Release – Controls the release time after the “attack”. For most applications (including this one), the recommended attack time is shorter than the release time.

Tel: +359 56 820027, Fax: +359 56 836700
The Soft and Hard limiters are used to restrain in limits each of the bands to prevent distortion in the processing control system. The limiters precede the main clipper and as per the other processes, each of the parameters can be changed as per the user’s requirements. As when audio processing is considered most settings are an ‘artistic’ choice, there are no recommended values.
The settings to be applied are identical for each of the subsections and are described in details
below,except for the look Ahead and Limiter Link options that are available in Soft Limiter only.
Drive - it is intended to create more or less gain at the input of the band. When setting the drive, note that:
• Increasing the drive will lead to reduction in the gain created by the band process. This will make up for the very low levels.
• A very low drive will prevent low level corrections’
Attack – controls the time needed for the reach of full compression once the threshold level has been exceeded. For instant compression, fast attack time should be set. In order for the compression to be increased gradually, slow attack time, allowing for more variations in the signal should be set.
Release – controls the time needed for the compressor to stop, once the level has fallen below
the specied threshold. Setting short release time will make the compression much more
adaptable to the input signal, but on the other hand may cause fast changes in the gain that may sound unpleasant. Setting longer release time will produce even signal with less distortion, but the small variations in signal level will be ignored.
The Attack and Release times should be conformed to the type of the used audio material.
Plat Drive – Sets the drive into the multi-band that precedes the main clipper. The range is -10 to 10 dB.
Plat Attack – controls the time needed for the reach of full compression once the threshold
level has been exceeded.
Plat Release – controls the time needed for the compressor to stop, once the level has fallen
below the specied threshold.
Threshold – Sets the dB level at which the compressor will start working. Once the threshold is reached, compression will reduce the gain of the input signal according to the current Attack and Release settings
The Look-ahead function available in the Soft Limiter, allows for smoother gain changes with quicker attack rates. The longer the amount of look-ahead time is, the smoother the dynamics processing will be. This is great for preventing of unwanted transients, but must be used with caution so as not to remove desirable transients, such as the percussive music like drum hits. An option to turn [On] or [Off] the limiter is also available.
Limiter Link is a setting related to the Left and Right Audio channels. If set to [On] the channels will be processed together. If set to [Off] the channels will be processed independently. As when audio processing is considered most settings are an ‘artistic’ choice, there are no recommended values.
[Undo] erases the last change applied to the settings reverting them to their previous state. Please note that not only the last applied setting will be undone, all settings that are not saved will be disregarded. The opposite of [Undo] is [Redo].

The settings of the Stereo generator are applied through this section of the Web Interface.
General – three modes of operation are available. The output can be set to [MPX], [Stereo] and
[Mono]. The option [Bypass] is also available.
Stereo Adjustment – from here you can change the level and phase of the PILOT tone.
RDS Encoder – The DB6000-STC has a built-in RDS generator which, depending on your
preferences can be [Enabled] or [Disabled]. The RDS subcarrier level can also be changed.
Output Mode – Select the preferred output mode for Output 2– [MPX] or [Pilot]. Output 1 is
by default always set to [MPX].
MPX Clipper – intended to obtain the positive effects of the MPX limiter (the loudness)
without the unwanted side effects - uncontrolled noise levels. This process works directly on the audio signal. From here you can enable or disable the clipper. The MPX Drive is adjustable from
0dB to 10dB via the interactive slider.
MPX ITU Limiter – Limits the MPX Power as per the ITU BS412 directive. The authorities in
each country have set different parameters that should be observed. It is recommended your local authorization to be checked.

All basic elements of the RDS/RBDS are displayed on the screen – PI, PS, RT, TA/TP and etc.
Alternative Frequencies are represented as a list. The number of the AF can be set via the AF
Count slider. Once the needed quantity of AFs is set, the frequencies for each of them should be
specied.

Basic RDS

PI/CALL (Program Identication) – The PI code is your station’s ‘digital address’. It is a hexadecimal code that is assigned by an appropriate broadcasting authority in most countries, but in the United States the PI code is numerically calculated from the station’s call sign. We have provided a calculator utility within the DB6000-STC. An in-depth discussion of the mathematical calculation is given in RDS/RBDS Standard.
To use the PI calculator for US ‘K’ and ‘W’ call signs, simply enter call letters into the CALL box. The hexadecimal code will automatically be calculated into PI box. If the hexadecimal code for a US station is known, you may enter it under PI, and then the call sign will be calculated automatically into CALL box.
When PI calculator fails to calculate PI or CALL the corresponding box will be lled with ‘--
--’.

Tel: +359 56 820027, Fax: +359 56 836700
PS (Program Service Name) – This is the station’s “street name” that will appear on the receiver faceplate display. The PS can be up to eight characters in length (including spaces) and can be as simple as the station’s call letters: KWOW or KWOW FM, or a slogan: NEWSTALK or LIVE 95.
RT (Radio Text) – This is a 64-character block of plain text that the listener can select for visual display on the faceplate of the radio by pressing an INFO button on the receiver. This function is not available on many automobile radios for safety reasons, which has precipitated the frowned-upon practice of scrolling the PS eld instead. The Radio Text can announce song titles and performers, run special promotions or contests, or broadcast sponsors’ messages.
PTY (Program Type) – The PTY data ag identies the station format from a pre-dened categories. Many RDS receivers are able to seek the listener’s preferred format automatically. This means that a car radio can switch from a fading station to a stronger one that carries the same variety of music, though not the very same program, as provided by AF switching. The PTY function of RDS helps a broadcaster catch ‘transient audience’ share. The PTY code is not meant to change from song to song or to accommodate a top-of-the-hour newscast, however.
MS (Music/Speech Switch) – This ag simply indicates whether music or speech is the primary
broadcast programming.
TP (Trafc Program Identication) – The TP ag identies the station as one that routinely broadcasts trafc bulletins for motorists as part of its normal, everyday programming. When the TP ag is displayed on the receiver faceplate, the radio is searching for trafc announcements. The
radio keeps track of TP stations offering this service to speed up the search-and-switch process.
TA (Trafc Announcement) – This is a temporary ag added to the RDS data stream only when a trafc bulletin is being aired. Some RDS car radios can be set to search for trafc bulletins
among various TP stations while tuned to a listener’s preferred program, or even while playing
a tape or CD. As soon as any TP station broadcasts a trafc bulletin, the receiver temporarily switches-over to receive it. When the bulletin is nished, the receiver switches back to the original
program, tape or CD.
DI (Decoder Information) – This is one of several ‘ags’ that convey yes/no or other very basic data. This particular ag tells the receiver whether the broadcast is monaural, or is being
transmitted in any of several methods of stereo or binaural broadcasting.
List of Alternative Frequencies – A network broadcaster, or one with low-power rebroadcast
transmitters (translators) to ll holes in his coverage area, can include a list of all frequencies where
the identical program can be heard simultaneously. The RDS receiver (particularly the upscale car radio) constantly searches for the best signal that carries the very same program. When a better signal is found, the radio re-tunes with no noticeable interruption. The principal utility of this RDS function is with European radio networks and US stations with ‘translators.’

Dynamic PS ‘marches’ the message across the display screen one character at a time. The
message requires a much longer transmission time in this mode, but a glance at the radio display a few seconds still allows the driver to get the full message without missing words.
Scroll Speed – The speed of dynamic PS messaging is set here, or dynamic PS messaging can be turned off entirely. When 0 - DPS Disabled is selected, the dynamic PS message remains in the nonvolatile encoder memory, but only the 8-character default static “street name” typed into the PS eld (Basic RDS) will be displayed on the receiver faceplate. Setting the speed at 1 - Slowest will result in the slowest refresh rate of the ‘block’ message, or slowest safe scrolling. 9 - Fastest is the fastest speed, but many RDS radios display gibberish at high speed settings. The display should be stable with any radio at a speed setting of 7 or lower.
Parse Mode – sets the scroll step to be used in the “block” mode message transmission, more popular as ‘grouped-word’ method. Once Parse Mode option is set, this encoder function is valid for any scrolling-PS message, whether it is entered into the static DPS register, or received as ASCII text from station automation. Very short words are sent together in groups. For example, THIS IS constitutes seven characters that can be sent as a group. The same is applicable for OF THE or NOW HERE, also. Longer words, up to and including 8 characters, are sent individually: WARNING or DOUGHNUT or BICYCLE. The device can either center words that are sent individually on the radio display or left-justify them. This will be covered along with the function of the ‘DPS Scroll Step’. Words that exceed the available 8 characters are ‘sidestepped’ through two or more consecutive displays. Examples: EMERGENC followed by MERGENCY, or SUPERMAR followed by UPERMARK and PERMARKE and ERMARKET. This method of splitting words gives a good

sense of continuity and readability. Setting Parse Mode to 1 - Scroll by 1 letter will scroll the message one character at a time, as described. Other numbers also safe-scroll the message, but at 2, 3, 4, and up to 8 characters at a time. Selecting 9 - Left Justied will parse, as described, but text
will be left-justied rather than centered on the display. 2 through 8 may be useful in some special
RDS applications, but 0 and 1 are the primary Parse Mode selections. To recap: 0 - Centered will enable the more-popular, centered-auto-parsed block mode and 1 - Scroll by 1 letter the Dynamic PS, letter-by-letter option.
Radio Text
RT Speed – The Radio Text update rate is programmed by setting RT Speed =n , with n a number
between 1 and 9, corresponding to a refresh rate between slow and fast, respectively. Keeping the throughput tradeoff in mind, unless Radio Text is being used for contests or for other quasidynamic activities, it is best to use a lower number. A rate of 1, 2 or 3 will make little difference in the speed of other RDS functions.
Radio Text can be turned off entirely by setting: RT Speed=0. A zero value in this eld turns
the Radio Text message off, but does not delete any saved message from memory. The RT (Radio Text) is set in Basic RDS tab.
PTYN (Program Type Name) Settings
PTYN – Program Type Name is transmitted as 8-bit characters. PTYN must only be used to enhance Program Type information and it must not be used for sequential information.

HOW TO CONNECT TO THE RDS CONSOLE

The RDS console is used to edit the RDS settings in real time. It can be used with an automation software or a terminal program.
To use the console, follow the steps listed below:
1. Connect to the TCP port of the RDS console with a terminal program or an automation software;
2. A welcome message HELLO will be received if proper connection is established;
3. If password is needed, the following message will appear PASS?;
4. Proceed with entering the commands.

RDS Console syntax

HELLO
pass8
PASSOK
PI=12348
OK
PI?8
1234 OK
TP=38
NO
Depicted above is a sample RDS console conversation when a password is not set. The red text
represents the user input and the black text - the console’s responses. The 8 symbol represent the Enter key on the keyboard.
• First row – is the welcome message from the RDS console. Next the user types in the password (in this case ‘pass’), followed by Enter.
• Third row is the response meaning that the password is accepted and the user may proceed with commands.
• Fourth row is a ‘set’ command. These types of commands are used to set new value to RDS parameters. In the example above ‘PI’ is the Program Identication command, ‘=’ (equal sign) means set new value and ‘1234’ is the new value. The Enter key represents command’s end and signals the RDS console to execute the command.
• Fifth row is a positive response from the RDS console. It means the command is accepted and executed successfully.
• Sixth row is a ‘get’ command. These types of commands are used to return the current value of RDS parameters. In the example above ‘PI’ is the Program Identication command, ‘?’ (question mark) means return PI’s value. The RDS console responds with the current value (in this case ‘1234’) and positive response on the next row.
• Ninth row is again a ‘set’ command. In this case: Set Trafc Program to 3. The response is
negative because the parameter TP can only have value 0 or 1.

All the needed settings to the outputs can be applies through here. Each of the available outputs
is separated in different sections.
Digital Output / Analog and Headphones Output – is intended to control the peak output
level of the digital and analog output. A De-emphasis option is provided on both the analogue and digital outputs. The following control options are available – FLAT (off), 50μs (for Europe) and 75μs (for North America).
The Digital Output should be internally or externally synchronized in order to be functioning
correctly. This is specied by the Sample rate setting. If the synchronization should be made
internally, a value from the standard range of 32 to 192 kHz should be chosen. If the synchronization method is external, the relevant option should be selected from the drop-down menu. When External synchronization is chosen, Sync loss s.r. and Sync tout should be set in order for possible loss of the audio at the digital output to be prevented. If such is present, the DB6000-STC will
switch to internal synchronization (the value being specied in Sync loss s.r.) after the dened Sync Timeout expires.
MPX Out Level should match the one of the transmitter (or link device if one is used).

HD Time Alignment – Because of the time delay in the digital portion of the HD Radio audio
path, the analog and digital signals are supposed to be time-aligned. When the alignment is correct, the transitional blend from analog to digital or vice-versa will be almost transparent. When setting this parameter, have in mind that a time-alignment error of 1 millisecond will cause spectral notches during transition which will be audible by the listeners.
IT IS RECOMMENDED when the HD time Alignment is not used, the slider (value) to be set
to 0 ms as by default. Otherwise the result will be undesired audio delay.

APPENDIX A

RDS: EUROPE VS AMERICA

The European Broadcasting Union (EBU) and its member countries originated the concept of
“Radio Data” transmission. The European RDS specication, CENELEC Standard EN50067, was rst published in 1984. It was revised in 1986, 1990, 1991 and 1992.
European RDS has grown in use following initial adoption of the Standard. RDS is nearly
universal throughout Europe; it is almost impossible to nd a European FM broadcasting station
that does not carry a radio data subcarrier.
The popularity of RDS in Europe is very much in contrast with initial reluctance on the part of US broadcasters to embrace this technology. This can be ascribed to material differences in broadcasting practices.
Almost without exception, FM broadcasting in the United States is ‘detached’ and independent
- each station originates its own programming. America’s National Public Radio might be considered as an exception, though for most of the broadcast day even NPR stations originate, or at least schedule, their own programs.
Most of European broadcasting is similar to the concept of network radio that was common in the US prior to the 1950s. In Europe, a central program originator may have many transmitting facilities of modest power situated throughout the country, at several different frequencies to blanket a designated service area. The European disposition, toward lower-power transmitters can be found on the “local radio” level, as well.
The European concept of a service area equates to the US broadcaster’s market. The subtle difference between these designations further characterizes broadcasting practices and ethics.
RDS benets the European broadcaster through almost an altruistic endeavor to be of service to
his listeners. The US broadcaster is marketing his programming and is primarily interested in how he can create additional revenue from RDS.

THE RDS SYSTEM

RDS is a digital data channel, transmitted as a low-level subcarrier above the range of the composite stereo program signal in the FM baseband. The data transmission (baud) rate is comparatively low, yet it is quite robust because of data redundancy and effective error correction.
It is not within the scope of this Manual to cover the details of RDS subcarrier coding and
modulation. For this, the reader is directed to the Specication appropriate to his location either the CENELEC EN50067 Specication for Europe or the United States NRSC Specication. Since the Manual will deal with specic implication of RDS implemented with the DB6000-STC, it is
assumed that the user is familiar with the RDS concept.

APPENDIX B

HOW SHOULD I CONFIGURE THE CONNECTION BETWEEN MY DEVA DEVICE AND AN FTP CLIENT?

In order for a connection to be established the following setting should be applied:

1. FTP Server Settings

The built-in FTP Server has four important parameters that should be congured: Command
Port, Data Port, User name and Password. These parameters are to be used in the FTP client’s
connection conguration. Further information on how to change the FTP Server’s settings and
their respective default values can be found in the device’s User manual.
WE RECOMMEND the usage of FileZilla (https://lezilla-project.org). This is a widespread
open source software distributed free of charge, hence available for downloading from the Internet.
NOTE: The FTP Server can manage only one connection at a time. TheFTP Server works in
Passive mode. Hence, the FTP Client should also be set in passive mode.
2. IP Router and Port Translation Settings
If the connection to the device is made through a Network address translation (NAT) router or
rewall, the port forwarding feature of the router should be congured. The port forwarding is usually set in the rewall section of the router’s menu. As each router has different port forwarding procedure, we recommend you to refer to its complete manual. To allow proper data ow through
the router, the FTP Command and FTP Data ports should be open.
NOTE: The FTP port numbers to be used in the port forwarding feature conguration can be
found in the device.

3. Example of FTP Client (FileZilla) Settings
In some cases, FileZilla’s “Quick connect” feature is not able to connect with the DEVA unit. That is why we recommend the device to be assigned in the program manually.
Enter the FTP Client and go to: File > Site manager > New Site. A dialog box requiring obligatory information about the device will appear. Fill in the needed information and press “OK”.
Select “Transfer Settings” sub-menu and apply the settings as shown below:
