4429SDI Audio Extractor

1Introduction
he 4429 extracts up to two dual channel digital audio signals embedded in a serial
digital component video signal. he basic card provides AES3 digital audio outputs
in both balanced and unbalanced formats. Up to two optional DAC sub-boards are
available, each providing electronically balanced programme quality analogue
outputs.
he 4429 automatically adjusts to handle audio embedded either continuously or to
SMP E 272M. Equalised and regenerated copies of the digital video input are also
provided.
he module is designed to fit in the 1050 3U and 1051 1U Pro-Bel ICON modular
product rackframes.
Characteristics of the 4429 module are:
•extracts two dual channel audio signals from an SDI input
•balanced and unbalanced AES3 outputs
•high quality analogue outputs with one or two stereo DACs per module
•handles synchronous or asynchronous embedded audio
•compatible with COSMOS, Pro-Bel status monitoring

The 44 9 SDI Audio Extractor

he 4429 module extracts digital audio signals embedded in a video signal fully
meeting the SMP E 272M standard or the slightly different continuous format used
by Sony Betacam equipment. he module can extract any one of the four groups,
that is channels 1-4, 5-8, 9-12 or 13-16, but not combinations.

4429SDI Audio Extractor

2Installation
he audio extractor consists of a 4429 ICON module which uses the 30mm K4421.3
rear connector. here are five BNC connections for signal I/O and one 25 way ‘D’ type
female socket for the AES/EBU and analogue audio output. he 30mm rear
connector requires three slots in a 3U 1050 ICON frame and one module position in
the 1U 1051 ICON frame.

2.2Installing DA sub-boards
One or two 5635 DAC sub-boards can be fitted to the standard 4429 extractor at any
time to provide analogue audio outputs. DAC 1 provides analogue versions of the
first stereo pair, whilst DAC2 provides analogue versions of the second audio pair
from the selected group.
he converter should only fit one way round into the 4429 base module, since the
two header plugs are of slightly different sizes.
Proceed as follows:
•remove the 4429 base module from the frame
•fit the converter(s) as shown in the diagram, taking care to line up the pins with
the base board headers
•push the converter gently into its sockets, taking care not to bend any pins
•re-insert the module into the frame
Note: Removal and insertion of the 4429 module may be done with the frame
powered
Note: In this drawing the silkscreen writing on the 5635 ADC sub-board is shown the
right way up for clarity. he actual board may have inverted text.

3onfiguration
3.1Setting the operating mode
he rotary HEX switch, SW1, mounted on the front edge of the module sets the audio
group to be extracted as detailed in the table below. he asynchronous mode should
be used in situations where the embedded AES3 audio maybe unlocked.
Note: Each audio group selected can provide 2 stereo pairs or 4 mono signals. It is
not possible to select a stereo pair from one group and another stereo pair from a
different group. At any one time all audio outputs will originate from the same group
as selected by SW1.

3.2Enabling the audio outputs
AES output
he AES output of the extractor maybe enabled/disabled by jumper PL2 and is
described in the following table.
Analogue Audio output
he audio output of the extractor may be enabled/disabled by jumper PL3 and is
described in the following table.

3.3Setting analogue output levels
he analogue output levels of each 5635 DAC sub-module can be adjusted with RV1
for the right channel and RV2 for the left channel. he adjustment range is +15dBu
to +24dBu for Full Scale Digital (maximum digital word or clipping). Standard factory
setup is +18dBu=0dB, FSD for Europe and +24dBu=0dB, FSD for the US.

4Trouble shooting
Once configured, the module should not need further operational adjustments
unless signal or system requirements change. However, status LEDs are provided to
assist in the unlikely event that problems with configuration or module performance
arise.
In normal operation the following green LEDs should be illuminated, VD, AD, RA1,
RA2, Lock1, Lock2 and Power. No red or yellow LED should be permanently lit, but
may flash briefly during power-up.
4.1Sample problems and their solutions
The green video present LED, VD is not illuminated
•check that the input cable is connected securely to the BNC socket on the rear
panel
•check that there is a digital video signal of the correct format connected
The red error LED, ER is illuminated
•if this red LED is on, then there is no video signal present
•perform checks as for VD LED not illuminated
The green audio present LED, AD is not illuminated
•check that the input cable is connected securely to the BNC socket on the rear
panel
•check that there is a digital video signal of the correct format connected
•check Hex switch is set for correct mode of operation
12 chapter 4 Issue 1
4429

The green read FIFO LEDs, RA1 and RA2 are not illuminated
•RA1 and RA2 indicate the presence of either of the dual audio channels to be
extracted from the chosen group
•if audio present LED, AD is lit, a module fault is indicated
The green lock LEDs, LO K 1 and LOK 2 are not illuminated
•these LEDs monitor the output phase lock loops
•if only one audio channel is locked then only one LED will be illuminated
•LEDs will not be illuminated when module is in asynchronous mode
The red reset LED, RESET stays illuminated
•there is a fault with the module, this LED should flash briefly on power-up
The yellow initialise LED, INIT stays illuminated
•there is a problem initialising the card, this LED should flash briefly on power-up
The green LED, POWER is not illuminated
•check mains power to the frame is turned on
•if necessary check the PSU as explained in the power supply section
•check the card is plugged in securely
•check to see if one of the resettable fuses has operated, perhaps after recent
servicing work on the board. o do this turn the power off, wait for thirty
seconds and then restore the power
