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 Installation

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 R-

A110 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.

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.

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

DAP-781i | 11

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.

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.

The reserved part (T) of delay is subtracted from the accessible maximum fixed delay value. Up to four cards

can share the same tracking signal.

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.

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.

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.
