4.2 Connecting and Setting up Audio (AVSW-DVI8X8 only)
The 8X8 DVI-D Matrix Switch with Audio features two types of connections: balanced and unbalanced.
The balanced connection transmits a pair of balanced signals along two cables. Because interference will have the same intensity
and the opposite phases on the two cables, the two signals will balance each other. For the low frequency end of the audio signal
especially might be susceptible to interference across a long transmission. The balanced connection, therefore, should be used
where sound quality is a premium.
The unbalanced connection transmits signals along one cable, and is more easily subjected to interference. It is recommended that
this connection be used for consumer electronics or in instances where the need for superior quality is not an issue.
The Matrix Switch features an impedance control to enable you to adjust the impedance, which reduces the noise across a long
cable run.
