Gefen EXT-HDKVM-LAN Manuale Utente

page | 39

Audio works in both unicast and multicast modes.  The only difference between the two 

modes is that the 

Mic In jack is automatically disabled, on all Receiver units, in multicast 

mode.  To illustrate how audio works with the HD KVM over IP, we will set up a microphone 

and some speakers.

1.  Our computer has a 

Line In jack, as part of the sound card and we want to be able to 

access this jack from the Receiver unit.  Therefore, connect the microphone to the 

Mic In jack on the Receiver unit. 

 

 

 

 

 

 

 

 

 

 

 

2.  In order to get the audio from the microphone into the computer, connect a 

3.5mm-to-3.5mm mini-stereo cable from the 

Line Out jack on the Sender unit to 

the 

Line In jack on the computer. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3.  Connect another 3.5mm-to-3.5mm mini-stereo cable between the 

Line Out jack on 

the computer and the 

Line In jack on the Sender unit.  Note that any audio device 

(e.g. MP3 player, etc.) can also be connected to the 

Line In jack on the Sender unit.

WARNING:  Do not connect the mini-stereo cable from the Line 

Out jack on the Sender unit to the Mic In jack on the computer.  

Doing so will result in audio “clipping” and may cause damage to 

the computer’s sound card.
