is connected to the loop through input BNCs. The module outputs 4
AES/EBU 75
Ω signals through BNCs on the rear panel.
The 8920ADC can modify the outgoing signal to provide channel swap-
ping, channel summing, tone and phase inversion. The remote control
capability supports mode selection and input gain control.
The 8920ADC features:
• 24-bit resolution,
•AES/EBU loop-through reference input,
• 48 kHz sampling rate,
•Terminal block input via adapter,
• Independent input level control from +12 dBu to +28 dBu,
• 8900 Series Frame compatibility,
•Remote control via ethernet frame I/F,
•Newton Control Panel,
•SNMP monitoring, and
•Remote control lockout via onboard jumper.

Installation
Installation of the 8920ADC module is a process of:
1.
Placing the module in the desired frame slot,
2.
Cabling and terminating signal ports, and
3.
Configuring the module.
The 8920ADC module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indica-
tors reflect the initialization process (see Power Up on page 11).
Frame Capacity
The 8920ADC module can be installed in all 8900 Series frames but with
varying maximum quantities determined by frame cooling capacity.
Table 1 provides the power capacity, cooling capacity, and maximum
module count for each frame type.
Note Module capacity figures assume no other modules are in the frame.
Module Placement in the 8900 Frame
There are ten cell locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to Figure 1 on page 9.
The two cells on the right are allocated for the power supplies. For addi-
tional information concerning the Power Supply module, refer to the Gecko
8900 Frame Instruction Manual .
The third cell from the right is allocated for the Frame Monitor or 8900NET
Network Interface controller modules. These modules provide health mon-
itoring and control options.

Configuration
Configuration
The 8920ADC can be configured locally using onboard switches or
remotely using the 8900NET network interface GUI or a networked
Newton Control Panel.
Refer to the following sections for configuration instructions:
•Configuration Summary (page 13)
• Local Onboard Module Configuration (page 18)
•Remote Control and Monitoring (page 19)
Operation of these control types is explained in detail in their respective
sections of this manual.
Configuration Summary
This section provides a summary of all parameters that can be configured
on the 8920DAC module. Table 6 on page 17 provides a summary in table
format of all parameters and their ranges, default values, and remote, local,
and control panel function names and locations for setting each value.
The following parameters must be set on the 8920ADC module:
•Output level (Left and Right) – coarse and fine adjustment of analog
input levels for full scale digital outputs,
•Output mode – such as channel swapping, summing, tone and phase
inversion, and

14 8920ADC Instruction Manual
Configuration
Output Level Adjustment
To correctly adjust the 8920ADC for your digital application, determine
your maximum operating level and set the Coarse Level gain jumpers on
the module circuit board as described below. This is the level above which
digital clipping occurs.
Example Maximum Operating Level Setting
A setting of +24 dBu is a common maximum level. Using +24 dBu as the
maximum level, refer to Table 4 to select the lowest input level range that
includes the maximum level of +24 dBu. Select the Coarse Level Setting pin
4 to 5 jumper setting (refer to Figure 5 on page 18) because it is the highest
level supported by that range and requires the least amount of gain to bring
+24 dBu up to 0.0 dBFS level. This will give the best signal-to-noise ratio
that the system can deliver.
Setting Maximum Operating Level
Once you have determined the proper coarse level jumper setting, perform
the following steps:
1.
Set the Function Rotary Switch (SW1) on the front of the module circuit
board to the position marked 0 as shown at left.
2.
Remove the module from the frame and set jumpers on JP5 and JP6 to
the jumper setting that you determine using Table 4.
3.
Return the module to the frame.
Using Level Gain Toggle Switches
Note The toggle switches change input levels by increments of approximately
0.1 dB when held momentarily. Holding the switch up or down for about 1
second activates a continuous change mode that ramps the change rate from
about 0.1 dB per second to 0.6 dB per second. The yellow CONF LED will
flash slow (0.1 dB rate) or fast (0.6 dB rate) to indicate the change rate.

Configuration
There are three ways to adjust the onboard gain toggle switches to the
proper level:
•Apply the maximum level to the input (example +24 dBu) and monitor
the AES output with a meter that indicates digital level in dBFS and
adjust the toggle switch for each channel until the meter indicates
0.0 dBFS.
Because the toggle switches have a resolution of 0.1 dB, you may not be
able reach 0.0 dBFS exactly. Use the closest negative setting possible.
•Apply an audio level that is -20 dB below the maximum level, (+4 dBu
for the example, +24 dBu -20 dB = +4 dBu) and adjust the AES output
as indicated on a digital audio meter to -20 dBFS.
If you have no meters calibrated in dBFS you can use the tone output
position to compare with the output level. Tone output is position E on
the Function Switch and outputs a 1 kHz tone at -20 dBFS. Note the
internal tone level indication while monitoring the AES output and
switch back to 0 or F position on the Function Switch, then adjust the
gain toggle switch to the same level as the internal tone level.
•Apply the maximum level to the input (example +24 dBu) and adjust
the gain toggle switch for each channel until the clip LED comes on.
This is -0.5 dBFS, and by tapping the toggle switch four more times you
will be within 0.15 dB (worst case) of the correct gain setting.
CAUTION Using a maximum level that is larger than the high end of the range setting
jumper will result in a clipped waveform and high distortion. Use the next
higher jumper setting that includes the maximum level and readjust the gain
following the instructions above.

Configuration
Configuring Output Mode
The 8920ADC provides thirteen possible output configurations as shown
in Table 5. The module can be configured using the rotary switch shown in
Figure 5 on page 18. To make a configuration setting, rotate the switch to
the desired output configuration. The 16-position rotary switch selects one
of 13 possible output modes. Positions B and C are not used and positions
0 and F select the same mode—the factory default.
Remote Control Lockout
When a jumper is placed across pins 1 and 2 of jumper block JP7 (see
Figure 5 on page 18), module output mode settings are adjustable from the
Local on-board switches only. To have both Local and Remote access, set
the jumper across pins 2 and 3.

Local Onboard Module Configuration
The 8920ADC module can be configured locally to set parameters using the
jumpers, the rotary switch and two toggle switches shown in Figure 5. The
CONF LED indicates status of the configuration process.
These components perform the following:
• Jumper JP7 – sets control mode for Local only or Remote and Local.
• Jumpers JP5 and JP6 – set coarse input level adjustment for left and
right channels as explained in Setting Maximum Operating Level on
page 14).
•SW2 and SW3 (toggle) switches – provide fine adjustment of the left
and right channel input levels as described in Using Level Gain Toggle
Switches on page 14.
• Function (rotary) switch – selects a desired output configuration (0
through 9, A through F), although not all positions are used.
• CONF (configuring) LED – when on, indicates the module is initial-
izing or processing configuration information.
Note Function switch positions 0 and F (Factory defaults) can be used to return the

Remote Configuration and Monitoring
8920ADC configuration and monitoring can be performed using a web
browser GUI interface or a networked Newton Control Panel when the
8900NET Network Interface module is present in the video frame (Gecko
8900TFN-V frame). Each of these interfaces is described below.
Note For remote access, make sure the jumper block on the module is set for both
Local and Remote access (Figure 5 on page 18).
8900NET Module Information
Refer to the 8900NET Network Interface Module Instruction Manual for
information on the 8900NET Network Interface module and setting up and
operating the Gecko 8900 frame network.
Note The 8900NET module in the frame must be running software version 3.2.0 or
higher for proper remote and control panel operation. Upgrade software and
instructions for the 8900NET can be downloaded from the Grass Valley web
site.
Newton Control Panel Configuration
A Newton Control Panel (hard or soft version) can be interfaced to the
Gecko 8900 Series frame over the local network. Refer to the documenta-
tion that accompanies the Newton Modular Control System for installa-
tion, configuration, and operation information.
Control panel access offers the following considerations for module config-
uration 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.
•Update software for applicable modules and assign frame and panel IP
addresses with the NetConfig Networking application.
•Recommended for real-time control of module configuration parame-
ters, providing the fastest response time.
Note Not all module functions are available with the control panel, such as E-MEM
and factory default recalls. The available control panel controls for the
8920ADC module are listed in Table 6 on page 17.
An example of the Newton Configurator is shown in Figure 6 on page 20.

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 func-
tions, including naming of inputs and outputs, factory parameter and
name default recalls, E-MEM functions, slot configuration, and SNMP
monitoring controls.
•Web access will require some normal network time delays for pro-
cessing of information.
•Configuration parameter changes may require pressing Apply button or
Enter, upload processing time, and a manual screen refresh to become
effective.
•Web interface recommended for setting up module signal and slot
names, E-MEMS, and reporting status for SNMP and monitoring.
Refer to the Frame Status page shown in Figure 7 on page 21. The 8900
modules can be addressed by clicking either on a specific module icon in
the frame status display or on a module name or slot number in the link list
on the left.
