AJA HD10AMA HD/SD 4-Ch Analog Embedder/Disembedder User Manual — Introduction
Introduction
The HD10AMA is a dual rate 4 channel analog audio Embedder/Disembedder. The
Disembedder is always functional providing 4 outputs. The Embedder is user
selectable, on a channel pair basis, to either “pass” input audio or embed input audio
from the breakout cable. Analog audio levels are selectable. The HD10AMA
automatically detects and configures to the input video standard.
Features
• Dual rate HD-SDI/SDI Embedder/Disembedder
• 4 Channel Balanced Analog Audio I/O
• Supplied XLR breakout cable
• HD-SDI/SDI input, 2 HD-SDI/SDI outputs
• Dipswitch configuration
• 5-18VDC Power

AJA HD10AMA HD/SD 4-Ch Analog Embedder/Disembedder User Manual — User Controls
User Controls
The user interface for the HD10AMA is an 8-switch
DIP accessible through a cut-out in the bottom of
the unit. Use the DIP switches to configure how the
Analog embedding and disembedding functions.
There is also a jumper on the internal circuit board,
accessible by removing the outer shell case of the
HD10AMA. Located by the DIP switch, this jumper
is used in conjunction with the DIP switches 1 and 2
to select certain functions—see the discussion later
on this page.
Note:
The combination of the AUX jumper
setting and the DIP switch settings determines the
overall operation of the HD10AMA.
The exact function of each DIP switch and what it
controls is described on the following pages.
DIP Switch Settings
AUX Jumper (inside case)—pass or delete ancillary data packets
The function of the AUX jumper is to delete all incoming ancillary data packets in both the
horizontal and vertical ancillary data spaces. In the default postion (OPEN), ancillary data
packets are preserved and passed through whenever possible (i.e., when audio packets for that
group are not being embedded).
To remove the case shell, simply remove the four phillips screws that fasten the back half of
the case shell (the half having the DIP switch access hole).

Switch 5: DISEMBD GRP L Right (1), Switch 6: DISEMBD GRP H Right (1)
Switch 7 (LEVEL)—Control Whether Audio Levels are Professional
Or Consumer. Affects all 4 Inputs and Outputs
:
Note:
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 dangerous 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.
Switch 8 (LEVEL)—Control Whether Audio Levels are High or Low.
Affects all 4 Inputs and Outputs
