SERVICE SWITCH USAGE GUIDE
The Sender and Receiver of the Gefen DVI Audio Extender both contain a set of
service switches (also called dip switches) located underneath each unit. Peeling
back the silver sticker will reveal the service switch bay. These service switches are
used to boost and equalize the signal to best match the conditions in your setup.
(*Note: Adjustments should be done with sources and display on. Switches 3 and 4
are not used.)
Sender Dip Switch Settings
Setting Switch 1 Switch 2
No Boost OFF ON
Normal Boost (Default) OFF OFF
Strong Boost ON OFF
Undefined ON ON
Receiver Dip Switch Settings
Setting Switch 1 Switch 2
No EQ (Default) OFF OFF
EQ Setting 2 ON OFF
EQ Setting 3 OFF ON
Maximum EQ ON ON
Adjustment Guidelines:
1) Strong boost should not be used on stranded cables. Strong boosting will
cause pixels or no picture on these cables.
2) Using the wrong settings will not damage the units; it will either produce no
image or a noisy image.
3) To eliminate the possibility of cross talk and interference, cables must be
terminated with 568B scheduling. (See page 6 for details)
