MODULE OVERVIEW
The 6040 Tracking Audio Delay module provides both bulk and variable delay to ensure
proper synchronization between picture and sound. The 6040 can track up to three video
synchronizer modules in the Avenue system and will respond when a frame is dropped or
replaced to provide accurate audio tracking. Delay settings are dynamically adjusted so
that the 6040 will "shrink" or "stretch" the audio as required over a period of 6 seconds
until the new settings are in effect.
As shown in the block diagram on the next page, two input sources, analog or digital, are
available via local or remote control. The digital input is sample rate converted allowing
for unlocked and/or off frequency digital sources to be used with 24-bit audio precision.
The digital input can also be used for non-audio sources such as AC-3 or Dolby E. In this
case the sample rate converter is by-passed allowing for full 24-bit precision data.
The module locks its audio to a Phase Lock Loop (PLL). The PLL can lock to the digital
input or an external reference as long as the signals are 48 kHz. If no reference is
available, or if desired by the user, the module can lock to an internal crystal.
The module incorporates three outputs; an analog output that can be switched between
delayed and non-delayed audio, an undelayed AES output (two outputs), and a delayed
AES output (six outputs).
Status indicators include indication of a valid external reference, error detection for the
AES input, error indication for any tracking errors, and indication of the bulk delay value.
Control of the module can be from one of the remote Avenue options or from the local
controls located on both the front of the module and on the inside of the module. Local
controls include bulk delay, input selection, analog output mode (delayed or non-delayed),
reference mode, digital reference level, analog input reference level, and analog output
reference level.
The on-board microprocessor communicates with the frame for remote control via the
Avenue System Control module if installed. Module ID (slot location, software version and
board revision) and status information can be monitored by the frame System Control
module and read using the optional interfaces available. Alarms can also be enabled if
desired.
Power is derived from the ± 12 volt frame power. It is regulated to the required voltages
for the module by on-board regulators. The module is fused with resettable fuse devices. If
a 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.

APPLICATIONS
Tracking an All Analog Path
The application shown below illustrates how the Model 6040 Tracking Audio Delay
module can track a video source through a Model 5300 Analog to Digital Video Converter
with the optional 5310 TBC/Frame Synchronizer installed. The 6040 can not only track
the 5310, but can compensate for the video delay in the satellite path.

Tracking an All Digital Path
The application below shows how the 6040 can be used in a digital path. Here, the 6040 is
used in conjunction with a Model 5450 Digital Video Frame Synchronizer. Both the 5450
and the 6040 can be used for monitoring.
Delaying Compressed Audio (non-audio) Sources
Another application for the 6040 is delaying compressed audio streams such as AC-3 or
Dolby E. In the illustration shown below, the 6040 locks to the incoming data stream (48
kHz only), delays the data using only the bulk delay value (tracking delay is set to 0), and
mutes the analog outputs. If the non-audio data is not at a 48 kHz sample rate, all of the
outputs will be muted. Note that the 6040 will automatically enter into this mode when it
detects a non-audio source on the Digital input.

Driving a 6040 Using a Single-ended (unbalanced) Analog Source
The 6040 has balanced transformerless analog inputs. The diagram below shows how to
drive a 6040 using a single-ended (unbalanced) source.
Driving a Singled-ended (unbalanced) Analog Source with a 6040
The 6040 has balanced transformerless analog outputs. This application shows how to
drive external equipment with single-ended (unbalanced) inputs. Note that the minus (-)
side of the balanced output stage is left floating; it should not be connected to ground.

INSTALLATION
Plug the 6040 module into any one of the ten slots in the 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 next 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 parameters for each Avenue module must be configured 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 that 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 6040 Parameter Table shown on the next page summarizes and compares the
various configuration parameters that can be set remotely or locally and the
default/factory settings.
If you are not using a remote control option, the module parameters must be configured
locally from the front panel encoder and both front panel and internal switches on the
module. Parameters that have no local control will be set to a default value. The Local
switches and internal on-board switches are illustrated in the Front Panel Controls
and Indicators and Internal Jumpers, Switches and Indicators sections following
the 6040 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen 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 the Avenue
PC section.
