GUIDE TO INSTALLATION AND OPERATION

1 AAP-1741 Four Channel Analog Audio Processor

1.1 Introduction

The AAP-1741 is a four-channel high quality 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 dynamic processing (compressor/limiter and expander) and/or Down
and Up mixing are proposed as options.

With a card-to-card Audio bus, the AAP-1741 provides processing for 8 channels originating from a video
card. Once processed, the signals are sent back to be embedded, and are also available at the analog
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, ensuring proper
alignment and matched delay. The AAP-1741 can work with one video card and/or one other audio
processor card.

An input audio signal status is also available indicating the input signal presence or overload.

The card is housed in a (DENSITÉ) frame, with a single or double width rear connector panel.
.

2 Installation

2.1 Unpacking

Make sure you have ordered and received the AAP-1741 and its associated rear panel. If any of the
following items are missing, contact your distributor or Miranda Technologies Inc.

• AAP-1741 4-Channel Analog Audio Processor

• One of the AAP-1741 Rear Panels (see figure)

• An ABUS flat cable

2.2 Installation in the Densité frame

The AAP-1741 must be mounted in a DENSITÉ frame. The installation includes both the AAP-1741
module, and the rear panel module. It is not necessary to switch off the frame’s power when installing or
removing the card.

When the AAP-1741 is used in conjunction with a video module such as FRS-1101 and/or another audio
module like AAP-1741 or UAP-1783, the ABUS flat cable must be installed between the ABUS
connectors.

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

middle one unplugged.

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

GUIDE TO INSTALLATION AND OPERATION

3 Operation

3.1 Control options

The AAP-1741 has two primary control interfaces:

• The local control panel attached to the Densité frame’s controller

• Remote control using Miranda’s iControl system

These will be explained in detail in the following sections.

3.2 Local control using the Densité frame control panel

Push the SELECT button on AAP-1741 card edge (see Section 1.5) to assign the local control panel to
operate the AAP-1741. 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 controller
card by a hinged connector, and when installed is
located in the front center of the frame, positioned in
front of the power supplies. 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.

3.2.1 Status LED

The status monitor LED is located on the front card-edge of the AAP-1741, and is visible through the front
access door of the DENSITÉ frame. This multi-color LED indicates module status by color, and by
flashing/steady illumination, according to the chart. The chart also indicates fault reporting for this card on the
DENSITÉ frame’s serial and GPI interfaces.
