8977AP-4B/-4U Digital Audio Processing Modules

Introduction

Two versions of the audio processing modules are available; the 8977AP-4B
with balanced audio (with the 8900BA-R rear module) and the 8900AP-4U
with unbalanced audio (with the 8900UE-R rear module.)

The 8977AP-4B and the 8977AP-4U modules provide audio processing for
four AES audio streams for delay, gain, sample rate conversion, and
genlock timing functionality.

Module Features

The 8977AP-4B and 8977AP-4U module features include:

• Up to 4 channels of AES audio streams (balanced or unbalanced
depending on the rear module type installed),

• Input audio receiver and output driver stages to restore and drive
signals over long coaxial or paired cables,

• Passing of PCM and Non-PCM audio signals (Dolby E),

• Performing sample rate conversion of the PCM audio signals,

• Provides genlock timing for the audio input signals with the
8900GEN-SM submodule to synchronize the audio input signals at
48 kHz,

• Audio delay management (fixed and/or tracking delay),

• Audio gain ensures the tuning of the level of each channel,

• Routing channel and audio processing module performs the selection
between two channels before applying dedicated processing,

• Pair routing module determines the allocation of the outputs of each
pair, and

• Remote control and monitoring support includes a web interface, a
Newton control panel, a NetConfig management system, and SNMP
monitoring with an application such as NetCentral.

Software Requirements

The front and the rear modules are delivered together as a set. Two choices
are available: one for balanced audio outputs with the 8900BA-R rear
module and one for unbalanced audio with the 8900UE-R rear module.

A 8900GEN-SM genlock submodule can be installed on the front 8977AP
module to provide a frame reference timing source.

The 8977AP-4B and the 8977AP-4U front modules can be plugged in and
removed from a GeckoFlex frame with power on without disrupting oper­ation on adjacent running modules. When power is applied to the module,
LED indicators reflect the initialization process (see Power Up on page 18).

An 8900NET module with software version 4.0.2 or later is mandatory for
configuring the 8977AP-4B and 8977AP-4U modules.

The Grass Valley NetCentral application must be running version 4.1.12.8A
or later for proper operation.

Module Placement in the GeckoFlex Frame

There are ten rear and front slot locations in the 2 RU frame to accommo­date audio and video modules. The 8977AP-4B and 8977AP-4U modules
can be plugged into any one of the GeckoFlex frame slots.

Note Use standard anti-static precautions when handling modules in the frame.

fall into other equipment and create a shorting hazard.

To install a rear module into the frame, follow these steps:

1. Unscrew the blank rear adapter cover (without removing the screws),

with a 2mm (5/64”) hex screwdriver (see Figure 2).

2. Remove the two retainer strips and the blank rear adapter cover using

a pair of needlenose pliers.

3. Insert the corresponding rear module in the slot.

4. Replace both retainer strips on each side of the rear module and tighten

the screws to secure the rear module.

Installation

8900GEN-SM Genlock Submodule Installation

Conditions

Before installing the 8977AP module, you will first need to determine if and
how you want to use a genlock reference or the available frame reference
buses. The genlock timing from an 8900GEN-SM submodule can be uti
lized in several ways. Refer to 8900GEN-SM GeckoFlex Genlock Instruction
Manual available online for a complete overview of using the genlock ref
erence.

In addition to the capability of providing a local external reference to this
specific 8977AP module with an 8900GEN-SM submodule installed, slots 1
and 3 of the GeckoFlex Frame have been specifically designed to distribute
an independent frame bus reference transmitted from the 8900GEN-SM
submodule mounted on another GeckoFlex module with this capability
configured for this purpose.

If another module with a genlock submodule installed has already been
configured and installed for frame bus distribution, you may configure this
module’s output timing to lock to the Frame Bus 1 or Frame Bus 2 reference
from the other 8977AP module. In this case, the 8977AP module does not
require the use of an additional 8900GEN-SM submodule.

-

-

The use of the genlock reference is determined by the setting of the Output
Timing on the System Config web page of the module and module place­ment in the frame and jumper configuration as summarized below:

• Local Reference – the 8977AP with an 8900GEN-SM submodule can
have a local external reference connected to the corresponding Refer­ence In BNC. This external timing reference will be fed to this specific
8977AP module only.

• Frame Reference 1 or 2 – when an 8977AP with an 8900GEN-SM sub­module is installed in slot 1 and/or slot 3, a frame timing bus can be
enabled to distribute the external reference connected to the corre­sponding Reference In BNC on the rear module to all modules in the
frame that can accept a genlock reference. Slot 1 provides Frame Bus 1
and slot 3 provides Frame Bus 2.

• Internal – when no 8900GEN-SM submodule is installed on the 8977AP
module, the Output Timing can be set to Internal so the output timing
will be in an internal freerun mode (delivered by a local oscillator).

Note The internal mode is mainly implemented for test and debug purposes during

the system setup of the module or in a standalone configuration where no
timing reference is required.

Frame Bus Jumpering

If you will be using this 8977AP module to distribute reference Frame Bus 1
(slot 1) or Frame Bus 2 (slot 3), you must set a jumper (GEN XMIT shown
in

Figure 4) on the front module circuit board for this purpose before

installing the module.

• Frame Bus 1 – to transmit the reference connected to the Reference In
BNC on the corresponding rear module on Frame Bus 1, set jumper J2
to

ENA (pins 1-2). This module must be installed in slot 1 of the frame

and configured on the Genlock web page (see the Genlock Web Page on

page 49) for

• Frame Bus 2 – to transmit the reference connected to the Reference In
BNC on the corresponding rear module on Frame Bus 2, set jumper J3

ENA (pins 1-2). This module must be installed in slot 3 of the frame

to
and configured on the Genlock web page (see the Genlock Web Page on

page 49) for

Remote Configuration

The 8977AP-4B and 8977AP-4U configuration and monitoring is per­formed using a web browser GUI interface or a networked Newton Control
Panel in the GeckoFlex frame (8900FFN). Each of these interfaces is
described below.

8900NET Module Information

Refer to the 8900NET Network Interface Module Instruction Manual from

4.0.2 version for information on the 8900NET Network Interface Module
and setting up and operating the GeckoFlex 8900 frame network.

Note Upgrade software and instructions for the 8900NET can be downloaded from

the Grass Valley web site. Refer to Contacting Grass Valley on page 4.

Newton Control Panel Configuration

Remote Configuration

A Newton Control Panel (hard or soft version) can be interfaced to the
GeckoFlex frame over the local network. Refer to the documentation that
accompanies the Newton Modular Control System for installation, config
uration, and operation information.

Control panel access offers the following considerations for module config­uration and monitoring:

• Ability to separate system level tasks from operation ones, minimizing

the potential for on-air mistakes.

• Ability to group modular products—regardless of their physical loca-

tions—into logical groups (channels) that you can easily manipulate
with user-configured knobs.

• Recommended for real-time control of module configuration parame-

ters, providing the fastest response time.

Note Some module functions are not available with the Newton Control Panel,

such as factory default recalls.

Web Browser Interface

The web browser interface provides a graphical representation of module
configuration and monitoring.

Use of the web interface offers the following considerations:

• Provides complete access to all module status and configuration func­tions, including naming of inputs and outputs, factory parameter and
name default recalls, E-MEM functions, slot configurations and SNMP
monitoring controls.

• Web access will require some normal network time delays for pro­cessing of information.

• Configuration parameter changes may require pressing
processing time,

• Using the Web interface is recommended for setting up module signal
and slot names, and reporting status for SNMP and monitoring.

bits and the Z bit, which carries the AES block frame position block
start. For the control and status bits in the CUV positions of each audio
channel, and the Z marker for each stream (pair of channels), there is a
buffer on the module that handles the asynchronous timebase slips
between the input and output AES stream frequency.

This buffer will drop or repeat an entire block (occurring every 192 sam­ples) of CUV bits when the two timebases cross a block boundary rather
than drop or repeat individual bits from the block.

A control is provided on the AES Outputs web page for enabling or dis­abling the controls bits in an AES signal called the AES C/U/V Bit Pass

to the 8900GEN-SM Installation Manual available online for complete details
using this submodule for timing applications.

Reference Restore

If the Primary source has failed and a Secondary source is selected and
valid, the following controls allow you to set the module to switch back to
the Primary automatically or manually and determine the amount of time
before the Primary is restored.

• Switch to Primary – set this control to Manual if you wish to manually return
to the Primary reference when it becomes valid or locked again or
to allow the module to switch back to the Primary reference.

Reference Switchback Delay – When the control above is set for Auto, set

•
the amount of time to allow between switching from the Secondary ref­erence back to the restored Primary. The switchback time has a
minimum recovery time of approximately 30 seconds to assure that the
Primary is locked and valid before the module switches back to that
source.

Primary - Secondary Phase Difference

This graphic is provided to show the total phase difference between the
Primary and Secondary reference signals. When the bar is green and
remains in the area before the horizontal indicator, the two references are in
a range where switching between the two will show no measurable distur
bance in the output video (approximately 72 ns).

When the phase difference is larger than the recommended amount, the bar
will indicate by showing a second red bar. This indicates that the phase dif­ference is now such that switching between the two references will show a
disturbance in the output. This can be caused by a loss of one of the refer­ences or a mis-adjustment in the reference output delay of either reference.
The total phase error shown in this graphic represents approximative 1
microsecond.
