embedder is user selectable, on a channel pair basis, to either pass input audio
or embed input audio from the provided breakout cable. The ability to pass
incoming ancillary data makes it possible to embed up to 16channels of audio by
cascading four units. Horizontal ancillary data (HANC) packets in compliance with
SMPTE 291M can also be dropped at the input. Analog audio levels are selectable,
via USB connection and Mini-Config software.
The 3G-AMA automatically detects and configures to the input video standard.
3G-SDI formats up to and including 2048x1080p 60 YCbCr 4:2:2 are supported
(see "Appendix A Specifications" on page 19 for a complete listing). SDI video
loops through the device with minimal delay. Loop through embedded SDI audio
supports up to 16 channels.
NOTE: 2048x1080p/psf 29.97 and 30 formats support a maximum of 8 channels
embedded audio.

Chapter 2 – Operation
Default Operational Settings
The 3G-AMA converter ships from the factory with the following configuration:
• Local (DIP switch) control.
• Input analog audio channels 1-4 are embedded to SDI output channels 1-4,
overwriting any existing embedded audio.
• Input SDI embedded audio channels 1-4 are disembedded to analog audio
output channels 1-4.
• All HANC packets pass from SDI input to output, except for embedded output
audio channels 1-4.
• Analog audio levels are set to 0 dBfs = +24 dBu (Pro 1).

3G-SDI Level B:
For 3G Level B signals, selects either the 16 audio channels of input Stream A or
the 16 channels of input Stream B for disembedding. This setting also controls
whether output Stream A or output Stream B will receive embedded audio. This
control has no effect if a 3G Level B signal is not detected.
Analog Audio Levels
• Select from Full Scale Digital settings of +24, +18, +15 (professional), or +12dBu
(consumer).

About Audio Levels
Professional audio equipment has much higher levels than consumer equipment:
a 0 VU reading corresponds to +4 dBu. Connecting a professional +4 dBu device
to a consumer audio input (-7 to -8 dBu) may produce overloading, whereas the
output of a consumer device probably does not have sufficient power to drive a
professional audio input. With consumer and semi-professional audio equipment,
a VU reading of 0 dB is typically referenced to -10 dBV, which is equivalent to -7.78
dBu.
Update Tab Screen
Use this Update tab screen to view the software version currently installed on the
converter or install new software.
NOTE: When discussing Mini-Converters, “Firmware” is software that will be stored in
the Mini-Converter’s non-volatile memory and used when it is powered up. This
is something different than the Mini-Config application software. The version
numbers shown in the Update screen refer only to the firmware.
Installed
This field shows the version of the firmware currently installed inside the Mini-
Converter.
Desired
This field shows the version of firmware embedded in the Mini-Config application
which you can install into the Mini-Converter by clicking the Update button.
Update
This button initiates a software update operation loading the “Desired” version of
firmware into the Mini-Converter’s non-volatile memory.
