DAP-781i

GUIDE TO INSTALLATION AND OPERATION

1 General

1.1 Introduction

The DAP-781i is a high quality, 24 bit digital audio processor that can process up to 8 discrete channels of audio.
Its I/O consists of 4 AES inputs and 4 AES outputs. The DAP-781i can be used as a stand-alone audio processor
for discrete audio signals or can be combined with a wide range of digital frame synchronizer/proc amps,
upconverters, cross converters, and the XVP-801i Cross / Up / Down converter. When working in conjunction with
a video card, the processed audio channels from the DAP-781i cards are made available to be embedded into the
video signals.

If the DAP-781i is equipped with the Dolby E™ decoder card option, it is possible to select any of the audio
channels coming from the video or the audio card to be decoded into 8 additional audio channels. A ribbon
connector carrying both audio and timing signals links the video cards with the audio card(s). Two audio
processing cards can be combined together to process a total of 16 audio channels.

The audio processors feature two distinct processing blocks: Input and Output. The input processing includes
delay level adjustments 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 delay introduced by an associated video frame
synchronizer. The output processing block includes mixing, an additional gain/ attenuation stage and full channel
shuffling.

2.1 Unpacking

Make sure the following have been shipped with your DAP-781i. If any of the following items are missing, contact
your distributor or Miranda.

• DAP-781i

• DAP-781i rear panel labels::

One for R-AX Symphonie rear panel

One for R-A110 rear panel

2.2 Mechanical installation

The DAP-781i must be mounted within a Quartet 2 or Symphonie housing frame equipped with an R-AX or R­A110 rear module in order to provide power and signal interfaces to the card.

It is not necessary to switch off the power on these frames when installing or removing the DAP-781i.

2.2.1 imaging Quartet 2 series frames

To install this card into Quartet follow these steps. For a closer look at card installation and removal, refer to the
frame’s technical manual.

1. Remove the frame’s front panel by rotating the thumbscrews counter clockwise. Pull on the handles.

2. Select an available slot. The rear module needs to be in place prior to the DAP-781i installation.

3. Carefully place the DAP-781i between a set of card guides and gently push the card towards the rear of
the frame until the card edge connector is secured to the back plane. The card's edge connector having
96 pins, it may be necessary to push lightly when connecting the two connectors. Pull lightly on the
card, verifying that it does not move.

4. Replace the frame’s front panel. Make sure to rotate the thumbscrews clockwise in order to secure it to
the chassis.

Note: When pairing the DAP-781i 8 Channel Audio Processor with an XVP-801i HD/SD Universal Video

Processor/Cross Converter to provide the XVP with external AES audio inputs and outputs, the ABUS cable
supplied with the DAP-781i card must be used to connect the 2 modules. When using a Quartet 2 housing
frame, only one DAP-781i card may be used. The XVP-801i must be installed in the top slot and the DAP-781i
in the lower slot (figure below) in either side of the frame. Use the ABUS cable supplied with the audio card to
connect the 2 modules.

GUIDE TO INSTALLATION AND OPERATION

2.2.2 Symphonie Housing Frame

It is not necessary to switch off the power when installing or removing a module from/to Symphonie. To install a

module, follow these steps. For a closer look at card installation and removal, refer to the housing frame's Guide
to Installation and Operation.

Rear Module Installation

Before installing, check that the rear panel corresponds to the card to install. If no rear module is present, follow

the procedure below to install it.

In order to maintain the inter-rear module spacing, make sure to remove and replace one rear module at a time.
That is, at all times, there must be at least 15 rear modules installed. To install a module, follow these steps.

1. Locate an empty compartment.

2. Make sure that the rear panel corresponds to the card to install, the Reference switch LK1 is used to
select the (75 Ω) reference source for the imaging module. Selecting LOCAL (LK1 position 2-3) drives
the reference signal, connected to the rear module, to the imaging module. However, sliding LK1 to
position 1-2, connects the imaging module to the Symphonie global reference.

3. Carefully place the rear module between the rear module guides (refer to Figure 2.4) and slowly push
the module towards the front until it rests against the rear panel. It may require a light pressure to
compress the EMI gaskets on.

4. Using a flat edge screwdriver, secure the top and bottom screws to the frame.

GUIDE TO INSTALLATION AND OPERATION

2.5 Applications

2.5.1 Synchronization

An external reference signal is required to synchronize the digital outputs.

The detection of the reference standard is automatic. An AES3 digital audio reference signal connected at the
AES Sub-D has a higher priority than any reference signal connected to the BNC jack.

The REF LED, when green, indicates that a valid reference signal has been detected. It will be orange if the AES
output signals are synchronized to the AES Input 1 and red in free-run mode.

When used in conjunction with a video processor, the reference source is the video module that delivers a 27
MHz reference signal (via the ABUS front panel connector). The REF LED will be green to indicate the validity of
this 27 MHz signal.

The relative phase between external sync signal and AES samples is respected for any case except for the Video
NTSC mode. For Video PAL mode, output samples are aligned with the start of the first line.

RA-110 rear panel The AES 110 Ω Sync input is located on "AES" Sub-D socket. The switch SW16 “REF110”

must be set on the LOZ position to properly terminate the line. Other syncs are connected on BNC "REF.IN". The
switch SW15 “REF75” must be set on the LOZ position to properly terminate the line. The second BNC is lined to
"REF.IN" input and may be used as loop-through. For this conditional use, the switch “REF75” must be set on the
HIZ position.

RA-X rear panel The sync signal must be connected to the "REF.IN" BNC connector. The switch SW15

“REF75” must be set to the LOZ position to properly terminate the line.

When used in a Symphonie frame, the module’s 75 Ω reference input can be connected to the global reference

signal (video or Word Clock only) instead of the signal on the REF IN connector by setting switch LK1 to position

1-2 (GLOBAL) on the rear panel.

GUIDE TO INSTALLATION AND OPERATION

2.5.2 Remote analog controlled tracking delay

For compatibility with previous video processors, like the DVP-101i and ASD-231i, the DAP-781i has an analog
tracking delay input on the rear RJ45 jack. An ABUS connection at the front of the DAP-781i overrides this input.
The module can delay the signal up to 2.73 sec (@48 kHz). A part (320 ms for 8 video frames) of the maximum
delay is reserved for the tracking delay.

The applied delay is the sum of a fixed user-adjusted delay (in 1 ms steps or on a sample-by-sample basis) and
a tracking delay coming from the video processor.

This signal is sent via an RS 422 path.

VPD signal VPD signal

Video Processing Module

Figure 14 : Tracking signal

The signal period corresponds to the maximum delay reserved by the main module (T) and the positive pulse
width (tproc) corresponds to the required delay. For a sudden variation, DAP-781i integrates this modification
within 15 sec for a variation of 40 ms.

2.5.3 GPI Outputs

Four open-collector GPI outputs (one for each channel) are available on the GPI socket. For each channel, the
output is dedicated to a no-lock condition on the digital input. In the absence of alarms, no current flows through
an output pin. These outputs are inactive when the alarms are disabled (ALRM menu, OFF selected).

3.3 Control

The DAP-781i can be controlled in three different ways:

• The card-edge push-buttons, 4-character display and status LEDs can be used to move through a

menu of parameters and to adjust parameter values.

• Miranda’s RCP-100 remote control panel can be used to access the same menu structure from a

remote location.

• Miranda’s iControl system can be used to access the card’s operating parameters from a remote

computer, using a convenient graphical user interface (GUI).

As the graphical interface is the most intuitive and easy-to-use method, it will be used as the basis for

describing the functionality of the DAP-781i is section 3.4. A full description of how to use the card
edge controls and the RCP-100 to access the menus is given in sections 3.5 and 3.6.

communication status, input signal and reference signal format and statuses. In some instances, they
relate to conditions defined through parameters settings.

Manual Card Configuration – green if the card is controlled remotely, yellow when locally
controlled.

Input Status – green if OK, red if an error has been detected

Ref Status – green if OK, red if reference is absent.

ABUS Multiple Card Configuration – green if configuration and card setup are OK, red if there
is a mismatch between the configuration and actual card setup.

The DAP-781i displays nine icons, which monitor these functions:

1 2 3 4 5 6 7 8 9

Icon Function monitored Icon Function monitored

1 Manual card configuration 6 On-board Dolby E Decoder presence
2 AES 1 input status 7 Dolby Decoder Bitstream status
3 AES 2 input status 8 Reference status (mouse-over shows source)
4 AES 3 input status 9 ABUS Multiple card Config/Presence
5 AES 4 input status

Move the mouse over an icon and a detailed status message appears below the icon. If the mouse is
not held over an icon, the message area below the icons cycles through all current error or warning
messages related to the icons.

2. The left portion of the window contains selection buttons for all the parameter groups, which

become highlighted when they are selected; the main panel then displays the group’s set of
parameters. Each of the groups is described in detail below. This section can be hidden/revealed
by clicking the arrow icon on the left side of the window.

3. The lower section of the window’s left side contains a pull-down menu and 2 buttons to quickly

access user groups.

4. The main panel contains all the parameters specific to the group selected. It may contain several

tabs to help manage the different parameters.

3.4.1 Audio Processing

The Audio Processing window (see figure 18) provides full audio processing and delay parameters for
the audio channels.

Figure 18 : Audio Processing group

Specific behavior with non-PCM audio:

Dolby E audio is supported in the DAP-781i. During frame-sync mode, when input video and reference
signals are not synchronized, Dolby E frames may be skipped or repeated.

In addition, for non-PCM audio, all level parameters (gain and attenuation), input swapping and phase
inversion are overridden to prevent any modification of the audio data.

16 | DAP-781i

GUIDE TO INSTALLATION AND OPERATION

At the top of the window are three arrays of channel monitors, indicating the status of the audio inputs
and outputs.

Signal presence indicators monitor audio channel presence and are related to the No Signal Detect
parameters defined in the Config Tab (see details below). The channel indicator is green when a
signal is present and yellow when a silence is detected according to the Threshold and Delay settings,
and the AES Channel Alarm Reporting check box. The indicator is gray when the AES Channel Alarm
Reporting checkbox is not selected in the Config tab.

Signal presence indicators monitor the audio channel presence at the output of the Dolby decoder

card and are related to the No Signal Detect parameters defined in the Config Tab (see details

below): the indicator is green when a signal is present and yellow when a silence is detected

according to the Threshold and Delay settings

.

Describes the type of audio signal at the AES inputs. The options are identified by name, and color­coded for easy visual identification:

• PCM orange

• AC-3 (Dolby Digital) pink

• DOLBY E blue

• N-PCM (other non-PCM) yellow

CH 1-4, CH 5-8, CH 1-4 (E) and CH 5-8 (E) tabs

Each of these tabs controls Levels and Fixed Delays for four audio channels; each channel is provided

with a set of controls. The (E) refers to the extended channels corresponding to the Dolby Decoder
output.

Levels sub-tab:

Grouped in pairs of channels, each channel has the following controls:

Level (slider and input box): Sets the audio gain from -96 to 12 dB in 0.5 dB steps. For non-PCM

audio, the level value is overridden to 0 dB.

Mute (speaker button): Mutes the selected audio channel
Phase Invert: When checked, inverts the selected audio channel phase. This parameter is not

available for non-PCM audio.

DAP-781i | 17

GUIDE TO INSTALLATION AND OPERATION
Lock: When checked both channel sliders move together for levels and delay.

Swap. When checked, swaps the two corresponding channels. This parameter is not available for non-

PCM audio and for channels 1-4 (E) and 5-8 (E).

Figure 19 : Audio Processing panel – CH 1-4 sub-tab

Fixed Delay sub-tab

Although the DAP-781i automatically matches audio and video throughput timing, provision is made
for the user to insert an audio delay offset from the nominal value, in order to deal with problems such
as lip sync errors and audio phase alignment in the incoming feed. For each channel, two sliders allow

to adjust the delay. The Coarse slider adjusts the delay in milliseconds (ms), from 0 ms to 2000 ms
while the Fine slider provides audio sample increments, from 0 to 47 samples.

GUIDE TO INSTALLATION AND OPERATION

The Config Tab

This tab sets the card’s behavior in the event of a loss or absence of audio signal. The Signal
Presence indicators are then triggered according to these settings. Signal absence is not monitored for
non-PCM input signals.

Threshold: Signal absence is declared when the signal level is lower than the signal threshold during
the selected period. The threshold can be set to a specific value: -72, -66, -60, -54, -48 dBFS. The

default value is –60 dBFS.

Delay: The signal absence period can be adjusted from 3 to 255 seconds in preset steps: 3, 5, 7, 10,

15, 20, 30, 40, 50, 60, 90, 120, 180, 210, 240, 255 sec. The default value is set to 15 seconds

Channel Presence Alarm Reporting: select which audio input channels to monitor for audio silences by

checking their boxes. This enables the signal presence indicators to turn yellow when there is no
signal present which activates the audio silence alarm. Otherwise, when checkboxes are not checked,
the signal presence indicators turn grey.

3.4.4 Dolby Decoder

This window provides control and status information for the optional Dolby decoder card. The decoder
supports PCM, Dolby Digital and Dolby E bitstreams.

The Control Tab

Figure 26 : Dolby Decoder panel - Control tab

The Bitstream Detection Mode dictates the action taken by the decoder for each type of input
bitstream. In Auto mode, the decoder automatically recognizes and decodes PCM, Dolby Digital or
Dolby E inputs bitstreams. If Dolby E is selected, the decoder recognizes and decodes only this type of
bitstream, otherwise the decoder outputs are muted. The same applies for the Dolby Digital selection.
If Mute is selected, all outputs are muted for any type of input. Mute mode disables the Dolby decoder.

26 | DAP-781i

GUIDE TO INSTALLATION AND OPERATION

The Input Selection determines the Dolby decoder input channel pair. The Source can either be AES
In for the DAP-781i AES inputs or V for Audio Bus In channels pairs from the video card, if present.

The Delay Compensation tab allows frame adjustment of the audio vs. video delay, the default value is

one frame for the Dolby Decoder board.

The Decoder Status section indicates the type of bitstream detected at the decoder input.
The Dolby Digital section is available only if the input Bitstream Detection Mode is Dolby Digital or if

Auto is selected and the detected input bitstream is Dolby Digital.
The Stream Select parameter selects the stream number to be decoded when multiple Dolby Digital

bitstreams are embedded within a single AES pair.

The AES Channel Select parameter selects which AES3 channel to use as the source for the Dolby

Digital bitstream if the Dolby Digital data is configured in Professional 16-bit format. If the selected
channel does not contain a valid Dolby Digital bitstream, the channel data will be passed to the
decoder output as a PCM signal.

The Listening Mode parameter selects the main channel output listening mode. If EX mode is
selected, it will be activated only if the Dolby Surround EX Mode in the Dolby Digital tab, Dolby Digital
Status section is indicated as Surround EX Encoded. If not, the mode will internally default to Full

mode.

The Pro Logic Decode Mode parameter enables Pro Logic decode processing for Dolby Digital and

PCM bitstreams.

The Downmix configures the Dolby decoder's downmixed auxiliary output. This output is an additional

channel pair added to the 8 main outputs. When the output is activated, the 2 auxiliary channels
override audio proc channels 7 and 8 corresponding to AES In 4.

The Mode parameter activates or deactivates the auxiliary output. In Auto mode, the downmix output
will take the Preferred Stereo Downmix Mode indicated in the bitstream, if present (see Dolby E and
Dolby Digital tabs). If this information is not present in the bitstream or if Manual is selected, the type of
stereo downmix will be the one indicated by the following parameter Type.

The Type parameter selects the downmix mode for the 2-channel auxiliary output between Lt/Rt,

Lo/Ro and Mono.

The Dolby E Program Select parameter selects a Dolby E program for routing to the downmix 2-

channel auxiliary output. This parameter is only available for Dolby E bitstreams. The amount of

available programs depends on the Dolby E Program Configuration (see Dolby E tab).

3.5 Menu introduction

Most DAP-781i parameters can be accessed and changed via an easy-to-use menu, accessible using the push
buttons and display on the front card edge (see section 3.1). The flow chart below outlines the entire DAP-781i
menu path. Each menu item is described in this section. The following points should be remembered when
accessing the menu.

Automatic display turn off after 1-minute interval

If the menu is currently being accessed and no push-button has been pressed for 1 minute, the DAP-781i
automatically turns off the display. A press on any push button [-], [+] or [SEL] will turn on the display without any
change on the current parameter.

Navigating through the menu

This section describes how to use the front panel push buttons to navigate through the menu.

[+] Press [+] to move down in the menu or to increase the parameter value. For example, if you are currently

at {I-1&2}, pressing [+] will scroll downwards through the selection {I-1}. Depressing [+] during an
adjustment will increase the parameter value at faster rate.

[-] Press [-] to move up in the menu or to decrease the parameter value. For example, if you are currently at

{PHSE}, pressing [-] will scroll through the selections {LVL}, {SWAP}, {DLAY} and {STAT}. Depressing [-]
during an adjustment will decrease the parameter value at faster rate.

[SEL] Changes to a menu parameter are stored immediately to non-volatile memory. For example, after the L

gain value has been set, press [SEL] and the new value is stored for the current format and DAP-781i
returns to previous menu.

[ESC] If [ESC] is pressed after changes to a parameter, the parameter is reset to the value it had prior to the

change, For example, after changing L level, press [ESC] the previous value is reloaded and DAP-781i
returns to previous menu. When on root menu, a press on [ESC] turns off the display.

3.6 Menu organization

The architecture of the menus is built around main menus and secondary menus. Display disappears after one
minute and will reappear by pressing any of the [-], [+] or [SEL] push-buttons. Default values are written with bold
characters.
