The Headphone Configuration Panel is shown in Figure 18. There are two headphone configurations that
can be chosen: “Independent Headphone” or “Redirected Headphone”.
The “Independent Headphone” feature enables the user to play separate music on the headphone and
speaker. For example, the user can use a multi-channel device (such as 5.1 surround sound) to watch a
movie while simultaneously using the independent headphone feature to make phone calls through a
VoIP Internet phone.
The “Redirected Headphone” feature enables the user to hear the same audio that is being channeled to
the front speakers. In this mode, once the headphone has been inserted the audio will be redirected from
the speakers to the headphone.
Please note that the “Independent Headphone” function requires two channels. Therefore, only six
channels will be available if “Independent Headphone” is being used.
