General Information

The long years of experience at the top level of broadcasting technologies, as well as the
undisputable expertise of our engineering team have brought forth a brand new audio processing
tool - the DB6400 FM and Digital Radio 4-Band Audio Processor.

The DSP-based Stereo Encoder guarantees precision of the MPX signal with advanced peak

control and two independently-congurable composite MPX outputs. The DB6400 offers perfect

audio clarity no matter what the source material is. A complete processing architecture: Wide
band AGC with “Intelligent Gating”, 4-band Parametric EQ, Advanced Bass and Treble Controls,
4-Band High Quality Sound processor with Fidelity control and Sound Impact, 4-Band Limiter,
FM Limiter with advanced distortion & pre-emphasis control and HD Lookahead Limiter.

Another feature that distinguishes the DB6400 from other products of its category is its Fallback
function. This cutting-edge device is able to detect signal loss. In the case of silence at the main
audio input, it automatically switches over to a backup source, thus ensuring a constant audio feed.

What is more, an e-mail notication is immediately sent which allows for an instant response on

the part of your technical support team. Through the use of a standard FTP client, you have the
opportunity to update the backup content at will via any PC. An additional asset is the automatic
return to the main audio source as soon as the default input is restored. All silence sense parameters

are user-dened.

Needless to say, the DB6400 comes with a user-friendly, comprehensive and well-organized
user interface. Access is available through the front panel, remotely via TCP/IP and by using the
WEB interface through iOS, Android or any other mobile device.

This one-of-a-kind device is the peak of DEVA’s engineering achievements combining simplicity
of use, affordability of price and top performance and employing an array of technical parameters
not found in any other device of its class.

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 70 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 DB6400 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 DB6400 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 DB6400 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.

DB6400 Power Supply Factory Settings are:

- 100 - 240 VAC

- 1 Amp Fuse

CAUTION: Permanent damage will result if improper AC supply voltage is applied to DB6400

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 DB6400 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.

DB6400 Location

The best location for DB6400 is as near as possible to the transmitter, so that its stereo encoder
output can be linked to the transmitter through a circuit path. It is mandatory that the cable used for
connection between DB6400’s MPX output, and the MPX input of the transmitter be as short as

possible. This will prevent any face distortion. If this conguration is not possible, the DB6400’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 DB6400 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 DB6400 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 DB6400’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 Main Level and Input>Analog
Aux Level. The reference level that could be set is between -8dBu to +24dBu.

As a general rule, when the Ref. level is properly selected, DB6400’s front panel AGC indicator
should vary from +10/-10 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 DB6400’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.

DB6400 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 Main Level and Input>Digital Aux Level.

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 DB6400 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 DB6400’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 DB6400’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.

SETUP WITH ANALOG PROGRAM INPUTS

DB6400 is fed with analog audio. The main program output is sent to the DB6400 Audio
Processor via XLR Connection. The MPX composite output is sent via BNC connection to the
transmitter’s MPX input. The audio processor output used is MPX OUT -1.

IMPORTANT RECOMMENDATION: It is mandatory that the cable used for connection
between DB6400’s MPX output, and the MPX input of the transmitter be as short as possible. This
will prevent any face distortion.

ANALOG CONNECTION WITH DEVA SMARTGEN 6.0

The DB6400 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 DB6400’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 DB6400 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.

Factory and User presets

FACTORY PRESETS

The DB6400 has an extensive set of factory presets and provision of 20 user ones. In order for
a preset to be selected/used, navigate to the desired preset and press the soft button labeled [Load],
and then [OK].

How to create and save a User Preset or How to customize your sound

As the factory presets cannot always suit every format and market, each of them can be used as

a basis for the creation of e new user-dened preset. Once you are satised with the result all the

changes could be saved.

IT IS RECOMMENDED the user presets to be created prior to the installation of the DB6400

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. Start by choosing an empty preset, or a factory preset that you would like to use for a basis of

the new one. The menu path is Main screen> Presets select preset and press the soft button labeled

[Load], then [OK] to conrm the change;

2. Go back to the main menu and select the Process icon - modify the parameters that you think

would improve the enhancement of your signal and will make your station’s sound unique.

Specifying the new preset name is mandatory. If not, the DB6400 will not assign a name and
the newly created preset will be saved as U10:DANCE (for example, if a factory preset is used as
a basis) or U7:-empty- (if user preset is used as a basis).

3. Once you have nished with the creation of your customized sound/preset, go back to the

Presets page and nd the modied preset. An symbol indicating that some changes are being
made will appear.

4. In order to save the changes, using the front panel keyboard, select one of the user presets

then press the [Save] button. A window requiring verication will appear. Conrm the changes by

pressing the [OK] button. The newly created preset will be automatically chosen as ‘active preset’.

NOTE: Unless the new preset is created by a qualied/experienced broadcaster, it is

recommended no general changes to the base preset to be applied, as this can lead to unwanted
signal distortion.

To set static IP, MASK, GATEWAY and DNS addresses, the DHCP should be disabled. In order
for the built-in DHCP client to be activated, the function should be enabled. When the DHCP

client is activated, all assigned values will be shown in the relevant elds on the “Status Screen”.

If due to any reason, the DHCP procedure cannot be completed, DB6400 will use Auto IP and will
generate an IP Address.

SNMP Agent

Specify Agent ID, Agent Port, Read/Write Communities, Manager IP, Manager Port and
Session Timeout.

Agent – enables/disables SNMP Agent.

PRESETS

The DB6400 has a set of 17 factory presets and provision of 10 user ones. A preset contains
all the audio processing path parameters that can be changed in the following tabs – AGC, EQ,
Enhancer, Multiband 1, Multiband 2, and Final Limiter. In order for a preset to be selected/used,
the [Load] button should be pressed (the active preset is illuminated in green).

Each of the factory presets can be used as a basis for creation of new user-dened preset. Once
you are satised with the result all the changes could be saved.

If the Presets are to be triggered via GPI, the option should be enabled via the relevant menu.
The same is applicable for the Dayparting. Edit dayparts is a shortcut to “Dayparts” settings page.

How can a user preset be made?

IT IS RECOMMENDED the user presets to be created prior to the installation of the DB6400

in the broadcasting chain. Otherwise, any drastic changed 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, or factory preset that you would like to use for a 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’.

NOTE: Unless the new preset is created by a qualied/experienced broadcaster, it is

recommended that no general changes to the base preset (if such is used) to be applied, as this can
lead to unwanted signal distortion.

Preset Lock

As many of the stations prefer to use the services of qualied personnel when creating the

perfect preset, the DB6400 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.

Presets Export

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.

INPUT

General – Several types of Main Audio Sources could be set – Main Analog, AUX Analog,

Main Digital, AUX Digital, MP3 Player and IP Stream.

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.

Fallback – DB6400 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).

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 DB6400 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. Up

to 3 URLs can be dened. Up to 63 characters can be entered.

• 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 DB6400 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.

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.

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.

AGC

The rst processing stage is the AGC. It works across a large band of frequencies, and is intended

to normalize the difference in the audio levels fed at DB6400’s input. The AGC effectively reduces
the volume if the signal is strong and raises it when it is weaker. Having the task is to even out the

variances and to create a consistent performance, the AGC has inuence over all the subsequent

processes.

AGC Gate – if turned [On], in the event of audio drops below the user set limit (in dB), this

threshold will pause the operation of the audio processor. Hence limiting the unwanted oor noise

when the signal is too low.

AGC – this section allows you to set the Drive, Attack and Release. When setting these

parameters, have in mind:

- Drive (dB) – depending on the value set, it will increase or decrease the gain at the AGC input.

Increasing the drive will compensate for the very low levels, and vice-versa - the low drive will
prevent the low level corrections at the input.

- Attack – set in dB per second, this value will dene the AGC’s speed of reaction to unexpected

volume increase.

- Release – sets the AGC correction speed in dB per second. It is not mandatory high Release

speed to be set, as the AGC is powerful enough tool. It is widely recommended the speed to be set
to 1dB/s and 1.5dB/s for classical music, and to 2dB/s for all other commercial programs.

High Pass Filter – this sections allows you to turn [On] and [Off] the HP lter that passes

signals with a frequency higher than the set HPF Freq (High Pass Filter Frequency), and attenuates
signals with frequencies lower than the set HPF Freq (High Pass Filter Frequency). If the Stereo
Link is turned [On], the audio processor will check for differences between levels of the left and
right audio channel, and if need be, will restore the levels at the output. This feature is very useful
for jazz and classical programs, as when applied to pop/rock programs it may lead to sound power
loss.

EQUALIZER

DB6400 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. 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. 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.

The graph placed on the bottom of the tab, 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.

ENHANCER

The DB6400 is equipped with real stereo enhancer intended to improve the existing stereo
image. However, bear in mind that it will not create stereo from mono sources.

The Stereo Enhancer can be either turned [On] or [Off]. The Stereo Width parameter sets the

stereo enhancement rate. The sufcient value widely recommended is between 20 and 40%.

DJ Bass can be either turned [On] or [Off]. It is intended to enhance the sound in the low-audio

frequency range.

Brilliance can be either turned [On] or [Off]. It is intended to control the output level of the

tweeter for proper relative volume between the treble and the low audio frequencies.

MULTIBAND 1 (MULTIBAND LIMITER)

Split-band ltering is a great technique where audio signal can be separated into different

frequency bands so that each band can be processed separately. Upon completion of the procedure,
the respective bands can be combined together to form a more coherent and dynamic sound.
Graphic visualization of the frequency bands is also available.

Processing – the multi band processing an unique algorithm that controls the gain in each band

so as to assure sound stability. The sound color is controlled by the Fidelity parameter. It allows
either a pure or a colorful sound texture to be obtained. The Sound Impact algorithm will keep
the original authenticity of the sound attacks (peaks). The [On] and [Off] buttons in this section
enable or disable generally the Gate, Sound Impact and Fidelity options for the bass, low, middle
and high bands.

NOTE: The Multiband process is very powerful and can absorb the important sound variations.

That is why is it not always necessary to use the AGC stage.

The Multiband limiters are used to restrain in limits each of the bands to prevent distortion in the
processing control system. Each of the parameters can be changed as per the user’s requirements.
The settings to be applied are identical for some of the subsections and are described in details
below.

Gate – When the audio drops below this user dened threshold limit, the DB6400 will freeze

operation band. When the signal is too low, this function will limit the oor noise.

Fidelity – This function controls the spectral balance between bands. For example:

• if the Fidelity = 0%, the bands will work independently and the sound will be more colorful;

• if the Fidelity = 100%, the bands will be linked to the spectral distribution at the input, and the

sound will be purer.

Sound impact – As explained, this option keeps the original authenticity of the sound attacks

(peaks). Pay attention when using the Sound Impact with value bigger than 6dB, as the average

power of the sound will be signicantly increased. In such cases, you may need to lower the band
limiter or nal limiter drive.

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’

• If you are not using the wide band AGC, we recommend the drive to the bands to be pushed,
so that the reduction to be sufcient and correct low levels.

Threshold – sets working limits for each band. It can also move bands from the background to

foreground and vice versa.

Attack – Adjust in dB per second to set the processors’ reaction speed for each band. When

setting the attack parameter bear in mind that:

• If lower value is set, the slower will the processor react.;

• If higher the value is set, the faster the processor react, thus controlling the rapid variations.

Release – is often associated with density. Indeed, the higher the release time is, the higher the

spectrum density within the band will be. When setting this parameter, bear in mind that the Band
processor is very powerful. Therefore, it is not necessary high release time to be set in order for
high density levels to be obtained.

MULTIBAND 2 (MULTIBAND LIMITER)

Multiband 2 (Multiband Limiter) is intended to prepare the processed audio for the nal limiter.

The applicable settings for each band have been simplied so as not to complicate the process with

useless parameters. For each of the limiters you can set Drive and Threshold.

Drive – It is intended to create more or less gain at the band limiter input.
Threshold – sets the limit for each limiter band.

Band Mix – This section allows you to dose the output level for each band, hence, obtaining

the best sound balance.

FINAL LIMITER

Stereo Limiter – set the stereo image reduction percentage required, compared with the

maximum rate of 100%. If you are already using the Stereo Enhancer, we recommend you use a
percentage value between 10 and 15%.

HF Limiter – set in dB the HF limiter is intended to increase or decrease the amount of high

frequencies to be processed.

HD Limiter – is developed and dedicated for high quality digital applications such as HD /

DAB / DRM. This is a ‘Look-Ahead’ type of limiter, the delay of which can be adjusted. When
used in this mode, the outputs are not limited to 15 kHz.

FM Limiter – as the HD Limiter, the FM Limiter is intended for the FM applications. In its

core, it is a very powerful clipper that controls the gain at the FM limiter input. Bear in mind that

increasing the FM limiter drive may lead to signicant sound distortion.

FM Pre-emphasis – set the preferred pre-emphasis type - Flat, 50μS for Europe and 75μS for

USA. This setting is applicable for the FM output only

RDS DATA

All basic elements of the RDS/RBDS are displayed on the screen – PI, PS, RT, TA/TP and etc.
The Alternative frequencies are also available, 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 DB6400. 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 ‘----’.

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.’

OUTPUT

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 USA).

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 DB6400 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

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 DB6400, 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:
