MODULE OVERVIEW

The 7600 module is an eight channel audio embedder or disembedder for 1.5 Gb/s high
definition or 601 serial digital video. Four AES ports automatically configure as inputs or
outputs depending on if the module is configured as a multiplexer or demultiplexer.

When configured as a multiplexer, the 7600 has one SDI video input that can accept
either HD or SD video and four AES audio outputs. These four audio streams are
embedded into the SDI video stream. AES inputs are sample rate converted, allowing the
use of asynchronous audio. The output of the module is an SDI video stream that contains
the original video signal and four AES pairs.

When configured as a demultiplexer, audio signals present in the incoming SDI video are
extracted and delivered as standard AES output streams on the AES BNCs on the rear of
the frame.

The 7600 includes a full-featured, eight channel audio mixer. The channel swap and
shuffle capability allows complete rearranging and remixing of audio channels. it provides
precise control over audio level, with up to 12 dB of gain to compensate for low level
sources. All audio processing is performed at full 24 bit resolution by a digital signal
processor (DSP).

Because the 7600 has simultaneous embedding and disembedding, it is an in-line
processor for embedded audio. It can take embedded content, adjust levels and re-map
channels, and deliver it to the output as an embedded signal.

The 7600 can be configured in one of four basic operating modes:

• 8 Channels AES Audio in, Embedded HD or SD Out

• Embedded HD or SD In, 8 Channels AES Audio Out

• Embedded HD or SD In, Embedded HD or SD Out

• 4 Channels AES Audio in, 4 Channels AES Audio Out

Modes are defined by how the Audio inputs are defined (AES or SDI) in the Audio In A
and B menus as described later in this data pack. Refer to the Applications section for
examples of each of these modes.

As shown in the block diagram on the following page, an HD or SD signal is fed to the
module for embedding of audio or audio extraction, depending on the mode chosen by the
user.

The module provides eight channels of digital audio processing. Digital audio inputs can
come from four AES ports and/or be disembedded from the HD or SD SDI input stream.
After processing, digital outputs in both AES and embedded form are possible.

There are four AES ports, consisting of the four AES BNC connectors on the rear of the
chassis. These BNCs become bi-directional ports. Each of them can either be an AES input
or an AES output. These four AES ports are associated with pairs of channels: Ch 1/2,
Ch 3/4, Ch 5/6, and Ch 7/8. A port will become an output if it has not been chosen as an
AES input in the Aud In A and B menus.

There are two disembedders on the input side referred to as A and B. These disembedders
are being fed the SDI video input stream in parallel and each of them can be independent­ly targeted to any of the four possible groups. The A disembedder will produce two pairs of
audio signals, referred to as SDI 1/2 and SDI 3/4.

7600-2

7600-3

The B disembedder will also produce two pairs of audio signals referred to as SDI 5/6 and
SDI 7/8. In the B disembedder, the SDI 5/6 pair corresponds to the first and second
channels in the selected group and SDI 7/8 is taken from the third and fourth channels in
that same group.

The disembedded audio can be processed with level adjustment and channel mixing, and
shuffling. It can then be embedded into the video output stream.

There are two embedders referred to as A and B to support the eight channels of audio,
one for each group. The embedders are placed in series with the A embedder first and the
B embedder second. Each embedder must be configured for operating mode and the
desired group (1 – 4) in which to embed the audio.

The configuration parameters for the embedders in the Audio Out menu are not identical.
There is no Replace All function for the B embedder as this function occurs in the
upstream embedder A.

Power for the module is derived from the ± 12 volt frame power. It is regulated to the
required +5 volts for the digital circuitry by on-board regulators. The required +3 volts for
the multiplexer circuitry is developed in a linear regulator running off the +5 volt supply.
The module is fused with a resettable fuse device. If the fuse opens due to an overcurrent
condition, the module will lose power. After pulling the module, the fuse will reset auto­matically requiring no replacement fuse.

The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), and power status (+5 volts or +3 volts) to the optional frame
System Control module. This information can be accessed by the user or set to register an
alarm if desired using the remote control options available.

Module parameters can be adjusted through the control system with Avenue Touch
Screens, Express Control Panels, or the Avenue PC Application. Individual level controls
are available for all 8 channels. Memory registers can be used to save the complete config­uration of the module, making it easy to change instantly between different configura­tions.

APPLICATIONS

There are four basic modes for using the 7600 module. Each of the modes is described
here.

8 Channels AES Audio in, Embedded HD or SD Out

As shown in the block diagram below, the four AES audio input BNCs on the rear of the
frame can be used to input external audio which is then multiplexed into the HD or SD
output stream. To configure this mode, set the In 1/2, In 3/4, In 5/6, and In 7/8 controls in
the Aud In A and Aud In B menus to AES inputs. Inputs can be shuffled if desired using
the Aud Mix A and Aud Mix B menu. Inputs must be embedded into the output stream by
selecting the type of embedding and the audio group number in the Aud Out menu.

Embedded HD or SD Out, 8 Channels AES Audio Out

As shown in the block diagram below, the four AES audio input BNCs on the rear of the
frame can be used to output AES audio which has been disembedded from the HD or SD
input stream. To configure this mode, set the In 1/2, In 3/4, In 5/6, and In 7/8 controls in
the Aud In A and Aud In B menus to SDI inputs. Inputs can be shuffled if desired using
the Aud Mix A and Aud Mix B menus. Muxing must be set to Off in the Aud Out menu.

In this mode, embedded audio from the HD or SD input stream is disembedded, shuffled
in the Audio Input Selector with the Aud Mix A and Aud Mix B menus if desired then re­embedded into the output video stream as shown in the block diagram below. To configure
this mode, set the In 1/2, In 3/4, In 5/6, and In 7/8 controls in the Aud In A and Aud In B
menus to SDI inputs. Inputs can be shuffled if desired using the Aud Mix A and Aud Mix
B menus. Inputs must then be re-embedded by using the Mux controls in the Aud Output
menu.

4 Channels AES In, 4 Channels AES Out

In this mode, 2 external AES BNCs input 4 channels of AES audio into the Audio Input
Selector as shown below. The 4 channels can be shuffled in the Audio Input Selector with
the Aud Mix A and Aud Mix B menus if desired then sent to the other 2 external AES
BNCs as outputs. To configure this mode, set the In 1/2 and In 3/4 controls to AES inputs
and the In 5/6 and In 7/8 controls to SDI inputs in the Aud In A and Aud In B menus. In
the Aud Output menu, turn Muxing Off.

INSTALLATION

Plug the 7600 module into any slot in the 1 RU or 3 RU frame and install the plastic
overlay provided onto the corresponding group of rear BNC connectors associated with the
module location. Note that the plastic overlay has an optional adhesive backing for
securing it to the frame. Use of the adhesive backing is only necessary if you would like
the location to be permanent and is not recommended if you need to change module
locations.

This module may be hot-swapped (inserted or removed) without powering down or dis­turbing performance of the other modules in the system.

CABLING

Refer to the 3 RU and 1 RU backplane diagrams of the module on the following page for
cabling instructions. Note that unless stated otherwise, the 1 RU cabling explanations are
identical to those given in the 3 RU diagram.

MODULE CONFIGURATION AND CONTROL

The configuration parameters for each Avenue module must be selected after installation.
This can be done remotely using one of the Avenue remote control options or locally using
the module front panel controls. Each module has a REMOTE/LOCAL switch on the
front edge of the circuit board which must first be set to the control mode you will be
using.

The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 7600 Parameter Table on the following page summarizes and compares
the various configuration parameters that can be set remotely or locally and the
default/factory settings. It also provides the default User Levels for each control. These
levels can be changed using the Avenue PC application.

If you are not using an remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 7600 Parameter Table.

Avenue module parameters can be configured and controlled remotely from one of the
remote control options, the Avenue Touch Screens, Express Control Panels, or the Avenue
PC Application. Once the module parameters have been set remotely, the information is
stored on the module CPU. This allows the module be moved to a different cell in the
frame at your discretion without losing the stored information. Remote configuration will
override whatever the switch settings are on the front edge of the module.

For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.

For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.

For setting the parameters remotely using the Avenue Express Control Panel option, refer
to the Avenue Express Control Panel data pack that comes with the panel option.
