1 ADX-172p Miniature Dual AES/EBU Audio Demultiplexer
1.1 Introduction
The ADX-172p/75/110 are members of the picoLink family of
miniature products. The ADX-172p is a miniature AES/EBU
demultiplexer capable of extracting 2 AES/EBU signals (4 audio
channels) from a 4:2:2 video signal. The ADX-172p is available
in both 75Ω unbalanced (ADX-172p/75) and 110Ω balanced
(ADX-172p/110) AES/EBU output version. The ADX-172p can
extract any of the four embedded audio groups in a serial 4:2:2
video stream and provides a re-clocked serial digital output. The
low cost and compact packaging of the ADX-172p make it ideal
for standalone application.

2 Overall view
Figure 2.1 and 2.2 illustrates the ADX-172p/75 and ADX172p/110 major parts and their locations. The multiplexed signal
is connected to the 4:2:2 IN BNC and the re-clocked video signal
is provided by the OUT BNC. The extracted audio channel is provided by the two AES OUT BNC (ADX-172p/75) or XLR (ADX172p/110) connectors.

3 Installation
3.1 Power Supply
The power supplies LKS-WSA and LKS-WSE, for 110V and 220V
operation respectively, are used to power the ASX-172p/75/110.
Each power supply provides a regulated +5VDC@750mA power
source. Plug the power supply into a wall or power bar outlet.
The ADX-172p uses a mini XLR-3 connector for its power needs;
figure 3.1 provides a detailed pinout of the male connector.

3.2 4:2:2 Input
Connect a 4:2:2 serial digital signal to the BNC labeled 4:2:2 IN.
The ADX-172p accepts a 4:2:2 serial digital video signal in either
525 or 625 lines format. The 4:2:2 signal must conform to the
SMPTE 259M-C standard.
Make sure that the 4:2:2 input signal cable has a maximum
length of 175 m (560’). Also ensure that all serial digital video
equipment are connected point-to-point. For instance, there
must be a point-to-point connection between the 4:2:2 IN BNC
and the source equipment. If a T-connector is used to connect
other equipment, the maximum specified cable length is no
longer valid.

4 Operation
4.1 Audio Group Selection
Miniature slide switches provide the audio group selection. Only
one of the 4 groups should be switched On; in the event where
more than one group is switched On, the demultiplexing operation is performed by default on group 1. Switching all groups Off
effectively disables all audio channels. Figure 4.1 indicates the
location of the miniature switch at the back of the ADX-172p.
Figure 4.1 ADX-172p Slide Switch location
4.2 Status LED
The bi-colored status LED, located next to the output end, is provided to identify any input error or power supply malfunction. The
following lists the possible situations:
Green: Indicates that the ADX-172p is powered and
has detected a valid 4:2:2 input signal.
Red: Indicates an error with the input signal has been
detected or simply, there is no input cable connected.
Off: The unit is not powered on. Check that it is
connected to the power supply, and the power
supply is properly connected to a power source.
