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 75unbalanced (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 If a T-connector is used to connect other equipment, the maximum specified cable length is no longer valid.

ADX-172p/75 The two AES/EBU signals are provided by the AES OUT BNC connectors.
ADX-172p/110 The two AES/EBU signals are provided by the AES OUT XLR connectors. Figure 3.2 provides a detailed pinout of the male con­nector.

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.
