System Operation
Wiring Configurations
The FOX AEX 108 can be used anywhere local audio-only outputs are required. The
following instructions describe integrating the FOX AEX 108 after a FOX matrix switcher for
routing to audio amplifiers or a DSP processor. It can also be incorporated before a
FOX matrix switcher for independent processing of source audio signals by a DSP processor
(see
Application Diagrams on page 3 for other potential applications). Each audio
extraction point works independently.
NOTE: Transmission of HDMI video with HDCP content requires two fibers.
1. Connect the fiber output (OUT) of the matrix switcher to the Rx port of an extraction
point on the FOX AEX 108.
2. Connect the Tx port of the same extraction point to the FOX receiver (Rx).
3. Connect the Tx port of the FOX receiver back into the Rx port on the matrix switcher.
4. Connect local 2-ch audio output to the Audio connector of the extraction point.
After the FOX AEX 108 and all connected devices are powered up, the system is fully
operational.
CAUTION: The front panel LEDs will blink repeatedly if multimode and singlemode SFP
modules are mixed in the system or if the wrong part number is assigned.
The unit does not work properly until the correct SFP module is paired with
the correct model.
NOTE: Upon startup, all Audio Signal LEDs blink together to identify SFP module. The
LEDs blink once for multimode and twice for singlemode. Afterwards, the LEDs
return to their normal signal presence indication.
If any problems are encountered, ensure all traditional and fiber cables are routed and
connected properly.
TIP: If problems persist, call the Extron S3 Sales and Technical Support Hotline (see the
Contact Information on the last page for contact numbers).
Changing the Input Data Rate
Use the recessed toggle switch on the front panel to select between 2G and 4G input data
rates. Cycle power to the FOX AEX 108 after changing between 2G and 4G.
NOTE: Selectable rates apply to all extraction points. They are not for individual inputs.
CAUTION: Ensure all fiber extenders within the system are compatible with the selected
input data rate.
