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.

2.1 Unpacking

Make sure you have ordered and received the DAP-1781 and its associated rear panel. If any of the
following items are missing, contact your distributor or Miranda Technolog ies Inc .

• DAP-1781 8-Channel Digital Audio Proces sor

• One of the DAP-1781 Rear Panels (see figures on page 6)

• An A-BUS flat cable

2.2 Installation in the Densité frame

The DAP-1781 must be mounted in a DENSITÉ frame. The installation includes both the DAP-1781
module, and the rear panel module. It is not necessary to switch off the frame’s power when installing or
removing the card.

Detailed instructions for installing cards and their associated rear panels in the Densité frame are given in
the Densité Frame manual.

When the DAP-1781 is used in conjunction with a video module such as XVP-1801 and/or another DAP­1781, the A-BUS flat cable must be installed between the A-BUS connectors on the front card edges.

• Note: for a two card installation, use the two end connectors of the flat cable and leave the
middle one unplugged.

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.
