Connecting Audio Equipment
If the
VIP
is equipped with the audio option, basically two audio channels
are available, called handset and audio in/out. Only one of these two
audio interfaces can be active at one time.
A handset can be connected to the RJ11 receptacle labelled Handset at
the front panel of the
VIP
. In order to select this audio interface check the
radio button labelled Handset in the Audio Configuration Page.
The input and output level ranging from 0...100% can also be set in this con-
figuration menu. Moreover, the coding mode at the sending side can be
set using the menu item Coding mode between two different modes or
switched off.
The audio decoder will automatically follow the selected audio coding of
the transmitter. In cases where the receiver is not capable of decoding the
selected mode, e.g. software decoder, an automatic so-called fall-back
to the next available audio mode occurs.
The second audio channel is available at the two cinch receptacles
labelled Audio In and Audio Out at the front panel of the
VIP
. To choose
this channel the radio button Line In/Out in the Audio Configuration Page
has to be selected. The level and coding mode settings apply to this chan-
nel in the same manner as described above for the first channel.
