Chapter 1 – Introduction
Overview
The 12G-AMA is a 4-channel analog audio embedder/disembedder Mini-
Converter. It supports 12G-SDI input and output up to 4K/UltraHD single link, with
fiber I/O including LC and ST options.
Analog audio can be embedded and disembedded simultaneously. Audio
disembedding is always functional, providing four analog outputs. Audio
embedding is user selectable, on a channel pair basis, to either pass SDI
embedded audio or to embed input analog audio from the breakout cable.
Analog audio operating levels are selectable, via USB connection and Mini-Config
software.
The ability to pass incoming ancillary data makes it possible to embed up to
16 channels of audio by cascading four units. Horizontal ancillary data (HANC)
packets in compliance with SMPTE 291M can also be passed through or removed
at the input.
The 12G-AMA automatically detects and configures to the input video standard.
12G-SDI formats up to and including 4096x2160p 60 YCbCr 4:2:2 are supported
(see "Appendix A Specifications" on page 22 for a complete listing). SDI video
passes through the device with minimal delay. Pass through embedded SDI audio
supports up to 16 channels.
NOTE: 2048x1080p/PsF 29.97 and 30 formats support a maximum of 8 channels of
embedded audio.

and updating software. It consists of an information area at the top that shows
the available Mini-Converters attached to the computer via USB, with a graphical
rendering of the selected Mini-Converter showing all the connectors and their
current state.
Colored text next to the connectors indicates the signal type and what the Mini-
Converter is doing:
• Blue text indicates the values automatically selected
• Black text indicates values that you have manually selected
• Red text indicates the Mini-Converter is not detecting a signal, or cannot
operate with the current user settings.
NOTE: Even if no output device is detected, the SDI connector text still shows the signal it
is outputting.

NOTE: Configuration settings in red will change based on the attached output device as
well as input signals. For improved accuracy and reliability, you should configure
the Mini-Converter only when the target output device is attached and input
signals are supplied at the inputs.
Screens are virtually the same on both PC and Mac, with subtle differences that
reflect the general look of the platform environment.

Status Message
Tabbed Screens
Selecting a Mini-Converter with the pulldown menu causes this application to
connect to the selected converter. The graphic of Mini-Converter and text below
it provides:
• Type of converter
• Firmware version
• Serial number of the unit
A status field at the bottom of the screen shows if your application is connected
and communicating with the Mini-Converter.
When configuring the Mini-Converter, select it from the top pulldown, view the
current settings and change any values. Making a change communicates that
new value to the Mini-Converter’s non-volatile memory.
Tabbed Screens
The Tabs delineate control screens with groups of controls for each type of task to
be performed.
The controls for the actual configuration parameters are specific to each Mini-
Converter type. When you click on any of the tab buttons, the pane below
the tabs will change to match your tab selection. Any changes you make are
immediately applied and will be saved, overwriting previous settings.

Analog Audio Outputs
Disembed from:
Choose which SDI embedded audio group will disembed its audio and send it to
the four analog audio outputs:
• Group 1 (Ch 1-4)
• Group 2 (Ch 5-8)
• Group 3 (Ch 9-12)
• Group 4 (Ch 13-16)
Audio-2 Tab Screen
Click on the Audio-2 tab to view and make changes to the packet processing and
audio level settings.
Packet Processing Control
HANC Data:
• Pass – All incoming HANC packets are passed unless the embedder settings
require all or part of them to be over-written.
• Remove – All incoming HANC packets are dropped before embedding any
new audio packets. The embedder settings determine all embedded audio
output. Disembedding is not affected.
NOTE: 2048x1080p/psf 29.97 and 30 formats support a maximum of 8 channels of
embedded audio. When one of these formats is present and embedding is turned
on, the PASS HANC setting will be ignored and all incoming packets will be
dropped before embedding any new audio packets.

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.
