1 DAP-1781 8 Channel Digital Audio Processor
1.1 Introduction
The DAP-1781 is an eight-channel high quality digital audio processor designed to work alone or with a
wide range of video converters, frame synchronizer proc/amps of the Densité series.
The card features two distinct processing blocks: Input and Output. The input processing includes Dolby
detection, Tone generator, delay adjustments, level controls and phase correction. Delay components
include a fixed delay of up to 2 seconds as well as a video tracking delay that will automatically track the
varying saw tooth delay introduced by an associated video frame synchronizer.
The output processing block includes full channel shuffling, an additional gain/attenuation stage and
mixing. Each odd output channel is a mix of any two input channels, and a 4-channel mixing is available
on the even output channels.
Additional audio functions such as a 16 channel dynamic processing (compressor/limiter and expander)
and/or Downmixing (5.1 to LtRt) and Upmixing (2.0 to 5.1) are available as options.
The DAP-1781 offers the possibility to integrate a Dolby-E encoder, a Dolby-E and AC-3 decoder, a Dolby
Digital AC-3 encoder or an upMAX
The use of a 16 channel card-to-card audio bus allows the DAP-1781 to work with one video card and one
other audio processor card. When connected to a video card, the DAP-1781 can process 8 channels of
audio originating from the video card; once processed, the signals are sent back to be embedded, and are
also available at the digital outputs.
Along with the audio channels, the Audio bus carries the timing, delay signaling and Dolby Metadata.
When combining cards together all audio processing is synchronous and in phase, ens ur ing pr op er
alignment and matched delay.
User-defined channel identification data may be encoded in the AES status bits. An input audio signal
status is also available indicating input signal presence or overload.
The card is housed in a (DENSITÉ) frame, with a single or double width rear connector panel. Based on
the rear module installed, the DAP-1781 is compatible with the AES3 or AES-3id digital audio standard.

GUIDE TO INSTALLATION AND OPERATION
3 Local control using the Densité frame c ontrol panel
Push the SELECT button on DAP-1781 card edge (see Section 1.6) to assign the local control panel to
operate the DAP-1781. Use the control panel buttons to navigate through the menu, as described below.
All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all
interaction between the cards and the outside world. There are no operating controls located on the cards
themselves. The controller supports remote operation via its Ethernet ports, and local operation using its
integrated control panel.
The local control panel is fastened to the front of the
CPU-ETH2 controller card, and when installed can
be accessed by opening the front door of the frame.
The panel consists of a display unit capable of
displaying two lines of text, each 16 characters in
length, and five pushbuttons.
The panel is assigned to operate any card in the
frame by pushing the SELECT button on the front
edge of that card.
• Pushing the CONTROLLER button on the
control panel selects the Controller card itself.
• The STATUS LED on the selected card flashes yellow
The local control panel displays a menu that can be navigated using the four pushbuttons located beneath
the display. The functionality of the pushbuttons is as follows:
[CTRL] Selects the controller card for status monitoring and adjustment
[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button
once enables modification of the value using the [+] and [–] buttons; a second push confirms the
new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC]
causes the parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC]
does not exit the menu system. To exit, re-push the [SELECT] button for the card being
controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the
selected card’s STATUS LED reverts to its normal operating mode.
3.1 Status LED a nd Report
The status monitor LED is located on the front card-edge of the DAP-1781, and is visible through the front
access door of the DENSITÉ frame.
This multi-color LED indicates m odule status b y color, and b y flashin g/s tea d y illumination, according to the
following chart. The state flashing red is the highest error level; the green state represents no error.
The chart also indicates fault reporting for this card on the DENSITÉ frame’s serial and GPI interfaces.

Move the cursor over an icon to see its current status in the message area below the icons. If there is an
error status, the message will appear automatically. If there are multiple error messages, the display will
cycle through them.
Green if the card is controlled remotely (iControl).
Yellow when locally controlled.
Green if OK,
Red if an AES error is detected (the error can be
Validity, CRCC, Parity, Biphase or No Lock)
Grey if detection is disabled (card used with a
single rear panel for a decoder card)
Note: Each input error can be masked
independently
Green if OK,
Red if an error has been detected or there is no
reference connected. The error message is

GUIDE TO INSTALLATION AND OPERATION
4.1 Audio Processing
4.1.1 Audio Processing - CH 1-4 to CH 13-16 tabs
The channels 1 to 8 represent the AES1 to AES4
digital inputs. When a video card is present, eight
extracted audio channels are available as channel 9
to channel 16. See Audio Processing/Config tab
for the input selection from the video card.
Signal Presence: At the top of this window are 16
indicators; they monitor audio presence and are
related to the No Signal Detect parameters defined
in the Config sub-tab (see details below). An
indicator is green when a signal is present and
yellow when a silence is detected according to the
Threshold and Delay settings.
It turns gray for a No Lock AES Input status.
• Note: these indicators appear in green for
non-PCM content.
CH 1-4 to CH 13-16 sub-tabs: each of these tabs
controls the input processing (Levels, Fixed Delays
and Configuration for the absence signal detection)
for two pairs of channels; each channel is provided
with a set of controls.
4.1.1.1 Levels sub-tab
Each channel has the following controls: a Level
slider (from -96 to 12 dB), an input box where the
desired level may be input directly, a Mute icon
button and a Phase Invert checkbox.
At the bottom are three checkboxes:
• Swap – allows channel swapping inside a pair, available only on channels 1 to 8. .
• Lock – locks both channel sliders together for levels and delay, so that moving one slider moves the
other one as well.
• Test – replaces the input signal with a stereo test tone.
Note: the Level sliders, the Phase Invert and the Swap checkboxes are inactive on non-PCM signals.
• Sample Rate converter – a manual selection of the input sample rate converter is available through
a drop down menu. Its primary use will be to turn off the sample rate converter to handle Non-PCM
data with an incorrect channel status (PCM/non-PCM bit).
26 | DAP-1781
27
4.1.1.2 Fixed Delay sub-tab
For each channel, two sliders allow delay to be
adjusted, with two levels of precision:
• Coarse – adjusts the delay in ms, from -250
ms to 2400 ms
• Fine – adjusts the delay in sample
increments, from -47 to 47.
Input data boxes are available to enter numerical
values directly.
The displayed value gives the delay between a card
input and a digital output.
The negative values will be applied only when the
DAP-1781 is slave of a video card via A-BUS. The
positive small values desired have to be larger than
the minimum processing delay to be effective.
If only one channel is non-PCM, the input sample
rate converter is bypassed for both channels
together; the remaining audio PCM chan n el w i ll
pass with its original sample rate, and possibly not
synchronized to the reference.
When a pair of channels is non-PCM, the even
channel setting is masked and the odd channel
setting is applied to both channels.
Note: an access is given through the Metadat a tab
to apply a fixed delay to the selected input
Metadata signal only.

4.1.1.3 Config sub-tab
This tab sets the card’s behavior in the event of a
loss or absence of audio signal.
• A signal absence is declared when the signal
level is lower than the signal threshold
during the selected period. The threshold
can be set through the pull-down box to –72, 66, -60, -54 or -48 dBFS, the default value is
–60 dBFS.
Delay: the amount of time for which the signal must
be below the threshold before a signal absence
error is reported can be adjusted from 0 to 255
seconds. The default value is set to 15 s, and an
input box is available to enter a numerical value

The pull-down box allows selection of the feed for
the 8 internal processing audio channels 9 to 16.
The two possible selections are A-BUS IN CH1-8 or
A-BUS IN CH9-16.
4.1.3 Dolby-E Alignment sub-tab
When a Dolby-E encoded signal goes through the
card, its timing versus the video reference is
controlled and can be adjusted manually.
The “Guard Band” refers to the number of audio
samples that do not contain Dolby-E audio data
around the defined video switch point. It is
intended to be aligned with the vertical interval
switch point of the video as defined by SMPTE
RP168 and is also restricted to odd fields, allowing
the Dolby-E data to be switched without
corruption.
• A click on the Auto Align button will
automatically adjust the audio timing delay to
ensure a perfect zero delay with the video.
This is equivalent to changing the audio delay
manually in the Fixed Delay sub-tab.
• This alignment implies that the DAP-1781 is
locked to a video reference either via A-BUS
and a XVP-1801 card or via a REF-1801.
• The measurement will reflect the Dolby-E
position at the outputs of the card.
The following table shows typical encoder output
positions, in time from the SMPTE RP168 reference
point to the SMPTE 377M header:
Note: without A-BUS, a consistent measurement
implies a minimum delay of one video frame applied
to a Dolby-E signal (33 ms + 18 samples @29.97
Hz, 40 ms @25 Hz).

GUIDE TO INSTALLATION AND OPERATION
4.6.2 UPMIX/DOWNMIX – UPMIX tab
This feature is used to create from a stereo source a
multi-channel compatible audio signal with up to six
channels, mapped on channels 9 to 14: Left, Right,
Center, Low Frequency Effect, Left Surround and
Right Surround. The stereo input signal is routed to
channels 15 and 16.
The selection of the stereo source is done with the
two pull down boxes Left Source and Right Source.
The pull down box Type offers three different
standard mixes and a custom position. The proposed
standard mixes are named Speech, Music and
Movie. For each standard, an Effect slider allows to
keep the Effect very light, with the slider down to 0, or
emphasized when going to 10.
The Custom position leaves all the settings available
to the user for specific needs.

4.6.3 UPMIX/DOWNMIX – DOWNMIX tab
This tab provides resources to control the downmix of a
“5.1 channel” surround-sound audio signal into an LtRt
or LoRo stereo pair. The 5.1 terminology refers to six
discrete audio channels, with the low-frequency channel
of limited bandwidth designated as the .1 channel. The
downmix can be done using any of the 16 audio
channels processed by the audio processor using the
Input Channels controls in the interface.
Input Channels: The default source channels are
CH1 to CH6, but the input shuffler allows any
combination of the input channels.
Downmix:
Operation Mode: Use the pull-down to select the
downmix operating mode:
• Manual: Downmix follows the downmix
parameters manually conf igured b y the user.
• Follow Metadata: Downmix follows the
downmix parameters of the Metadata.
Level Normalization: use the pull-down to select the
type of normalization to be applied on the downmix
output level.
• OFF: Downmix output level is not normalized. Clipping may occur depending on the input
channel levels and the selected mix levels.
• Level A: Downmix output level is normalized based on the applied mix levels to provide a
uniform output over the range of mix levels available. Clipping will never occur, even with full
scale input channels and mix levels.
• Level B: Downmix output level is normalized based on the channel configuration to provide a
uniform output loudness between 3/2 and other programs (2/0, 3/0, 2/1, 3/1, 2/2). For example,
downmixing a 3/2 program produces a loudness attenuation compared to the same program in
2/0 at the same input loudness. To provide a uniform output loudness, a loudness attenuation
is applied on all programs except 3/2. If the operating mode is Follow Metadata, the channel
configuration is given by the AC-3 coding mode parameter in the metadata. If the operating
mode is Manual, the channel configuration is given by the selected mix levels.
Table 2: Channel Configuration in Manual Mode
Level-B normalization also includes Level-A normalization, based on the applied mix levels.
Clipping will never occur, even with full scale input channels and mix levels.
Output Channels: The downmixed stereo pair is mapped into the channel pair selected in the pull-down
menu
Reversion Mode: Used only when Operation Mode is set to Follow Metadata. It determines which
downmixing configuration to revert to when there is no valid Primary (external input) Metadata. Downmixing

will use the Default Metadata Configuration if the Reversion mode is set to Default, otherwise it will use the
metadata parameters in the selected Backup Metadata (Metadata panel) when set to Bac k up Meta data.
Downmix Settings:
The Current Settings status indicates the current set of configuration parameters used for downmixing
depending on the Operation Mode and Reversio n Mode. If the Operation Mode is Follow Metadata,
Primary (external input) Metadata parameters shown in the Follow Metadata Config will be used. If the
Primary or Backup Metadata parameter is not present or not indicated, the corresponding parameter from the
Default Metadata Config will be used. If the Operation Mode is Manual, then the Primary/Backup Metadata
is ignored and the Manual Downmix Config will be used.
Follow Metadata Config:
This section reports on Metadata presence if the Follow Metadata Operation Mode is selected. The four data
boxes below the Metadata Input Presence status icon indicate the current Mode, plus the values in use for
Dialnorm, Center Mix Level and Surround Mix Level.
Apply Dialnorm: This parameter allows the dialog normalization level to be applied to the downmix. The
reference level is -31 dBFS. If set to ON, the applied level attenuation is the difference between the reference
and the value indicated in the the Dialnorm data box.
Manual Downmix Config / Default Me tada ta Config:
The heading of this area of the panel changes depending on the selection in the Operating Mode pull-down
above, but the available controls are the same in both cases.
• Operating Mode = Manual – the controls are used to set up the manual downmix parameters.
• Operating Mode = Fol low Meta data – the controls are used to set up the default downmix parameters
for situations where the Primary/Backup metadata is absent or when certain metadata parameters are
not present or not indicated.
Mode: This pull-down menu selects the downmix mode:
• LtRt: Enables the downmix of 5.1 channels into an LtRt (Left total Right total) matrix surround
encoded stereo pair.
• LoRo: Enables the downmix of 5.1 channels into an LoRo (Left only Right only) stereo pair, which is a
conventional stereo signal.
Dialnorm: This pull-down selects the dialog normali zat ion leve l. Se lect OFF to prevent the downmix from
applying the dialnorm. The OFF value is equivalent to the reference level of -31 dBFS. If set to ON, the
applied level attenuation is the difference between -31 dBFS and the value of the Dialnorm parameter.
Center Mix Level: Sets the center channel downmix level to the selected value.
[+3 dB, +1.5dB, 0 dB, -1.5 dB, -3 dB, -4.5 dB, -6 dB, Mute]
Surround Mix Level: Sets the surround channels (Ls & Rs) downmix level to the selected value.

Downmix Modes: Additional Information
LtRt:
This mode enables the downmix of 5.1
channels into an LtRt matrix surround
encoded stereo pair.
This LtRt downmixing process adds a
16.7 ms processing (801/48000 samples),
the minimum delay becomes 18.9 ms
(16.7 ms + 2.2 ms).
To keep control on the latency, when
coupled to a video card, the tracking delay
has to be larger than 19 ms, and with a
stand alone card select a fixed delay
larger than 19 ms.

LoRo:
This mode enables the downmix of 5.1
channels into an LoRo stereo pair,
which is a conventional stereo signal.
The LoRo downmixing process adds a
latency of 41.7 µs (2/48000 samples)
through the card. To keep control on
the processing delay, the tracking
delay has to be larger than 3 ms and
with a stand alone card select a fixed
delay larger than 3 ms.

Additionally the channels selected at the C, LFE, Ls
and Rs inputs are summed with the outputs of the
upmixing process.
This mode also allows a 5.1 audio present at the input to pass through. It will auto switch between a stereo
and a 5.1 audio source to provide a 5.1 output at all times.
• Set up the transition between the two modes to be unobtrusive by selecting transition speeds for each
case – upmix-to-pass and pass-to-upmix – using the t wo Auto MAX -II Transition Speed pulldowns
• Use the 5.1/2.0 Detection Threshold slider to set the level at which some 5.1 channels are considered
to be silent, identifying the input as 2.0

• Metadata Follow Mode & Reversion Mode
This process may be useful for sources that switch between 5.1 and stereo. The Coding Mode parameter in
the first program of the Dolby metadata will set the Operating Mode between PASS and UPMIX.
Note: In Follow Metad ata mode, the metadata Generator will be automatically turned ON when the
upMAX
TM
module is upmixing. The goal is to provide a valid metadata stream for the upmixed audio
content. The Generator content must have been previously configured with valid 5.1 metadata
parameters. The content of the Generator will be static except for the Dialnorm parameter of the first
program that will be continually overwritten with the Dialnorm value in the Primary metadata source
(when present). It is important to select an appropriate Backup Metadata source other than
Generator, configured with 5.1 metadata values, in case the Primary source becomes absent. When
the upMAX
TM
module is set to Pass mode by the incoming metadata stream, the Generator will be
automatically turned OFF to let the incoming metadata stream pass through.
* Generator: the Coding Mode of the Program 1 should be set to 3/2 or 3/2L
Adjustments
The “surround field” can be adjusted with the Center Width control and the Surround Depth control. The
bass enhancement signal for the LFE channel is derived from the Left, Center and Right channels. The LFE
Enable checkbox and LFE Channel Level slider control the LFE output.
Latency
This upmix process increases the delay through the DAP-1 781 by 155 samples (3 ms + 11 samples). It will
be compensated as soon as the requested delay is larger than 5.5 ms.
Note: in mode UPMIX and AUTOMAX, the channels 15 and 16 are reserved for a future use and muted.
Note: when a non PCM signal, including AC-3 and Dolby-E, is detected at the L/R input, the six outputs of

BUS is disabled, it is not possible to detect
other attached cards in the system.
• Slave 1 of Video Card – used for a two-card
system when the other card is a video
processor.
• Slave 1 of Video Card, Slave 2 is present –
used for a three-card system, with a video
processor and another audio processor
configured as Slave2.
• Slave 2 of Video Card, Slave 1 is present –
used for a three-card system, with a video
processor and another audio processor
configured as Slave1.
• Slave 2 of Video Card, Slave 1 is present, Serial Mode – used for a three-card system, with a video
processor and another audio processor configured as Slave1. The card Slave 2 is in Serial Mode.
• Master – the card is standalone, or used as a master for another audio processor configured as Slave.
This mode is not available when a video card is attached to the A-BUS.
• Slave of Audio Master Card – used for a two-card system when the other card is a audio processor
configured as Master.
Status:
• V Presence – turns green to monitor the presence of a video card in the A-BUS configuration.
• A2 Presence - monitors the presence of another audio card in the A-BUS configuration. The icon is
labeled A2 if this card is Slave1, and is labeled A1 if this card is Slave2.
Tracking Delay: When a DAP-1781 is a slave of a video card, the variable delay applied to the video signal
by the synchronization process is always applied to the audio signals. This tracking delay will also be applied
to a Metadata signal extracted by the Dolby decoder module; the Metadata output will stay synchronized with
its associated audio. The Tracking delay is not applied to a Slave car d in Serial Mode.

valid reference sources: one for a reference card
REF-17xx in slot 10 of the Densité frame, one for
a reference card REF-1xxx in slot 20, and one for
a valid AES1 input signal.
The URS is a single signal that is capable of
distributing to all cards in a Densité frame a
frequency reference and frame alignment
references for all video and audio signals.
Frame Rates:
The Frame rate is indicated for the A-BUS and URS sources of reference, as both types may be related to a
video frame rate.
When the external references are absent and the input signal to the Decoder is PCM, the Default Frame
Rate is used to output the Metadata stream generated for a PCM signal. See Dolby, PCM Control tab.
This Default Frame Rate is also used by an optional Dolby-E encod er card w hen a video ref erenc e is

also displayed in the upper left corner of the iControl Interface of the DAP-1781.
Note: "AES1 PCM Detected", "AES1 Non-PCM Detected", "AES1 Dolby-E Detected" and "AES1 AC3
Detected" appear as alarms when present. This is unusual, but it allows the user not only to select the exact
expected signal type for each AES input but also to select 2 or even 3 expected signal types.
As an example, the figure above shows the "AES1 PCM Detected" in red and "Disabled", in this case an
alarm will be raised if the AES1 signal is a Non-PCM, a Dolby-E or an AC3. No alarm will be raised for a
PCM type signal.
With the "standard" error generation, like "PCM absent" or "Dolby-E absent" errors, it is not possible to
watch a channel that would accept more than one specific signal type.
Activating Copy to other cards button opens a window which lists the similar cards, select the targets and
push Copy. A click on the column title will sort the cards accordingly.

GUIDE TO INSTALLATION AND OPERATION
Each alarm provided by a Densité card has an associated value, or key, that serves as a unique identifier.
An alarm’s URI, for example, contains its key. The Alarm Key can also be useful when creating scripts.
The Get alarm Keys button is used to save a list of the card’s alarms, the associated keys, as well as the
currently configured Overall and GSM contributions in a .csv file that can be viewed in any text editor or
spreadsheet application.
Refer to iControl 3.X User Guide for more information about Alarms Configuration.
4.17 Info
The Info panel provides information about the
DAP-1781.
The boxes titled Label, Short Label, Source ID
and Comments are editable – the user can
enter their own information.
The Advanced button displays the name of the
server within the iControl system, the frame in
which it is installed, the slot occupied by the
card and it’s ID.
The Remote System Administration button at
the bottom of the window opens a data entry
box titled Joining Locators, which lists remote
lookup services to which this DAP-1781 is
registered.
Add: Force the iControl service for this
DAP-1781 to register itself on a userspecified Jini lookup service, using the
following syntax:
jini://<ip_address>
where <ip_address> is the ip address of the
server running the lookup service
