Audio connections (audio versions only)
The audio versions of VideoJet 8008 and VideoJet 8004 have several audio ports
for audio line signals as well as a microphone input and a loudspeaker output.
The audio signals are transmitted two-way and in sync with the video signals. As
a result, you can connect a speaker or door intercom system at the destination
point, for example. When transmitting audio signals, a maximum of one input
and one output current is possible at the same time. However, several audio out-
puts can be connected with the same audio stream. Selection is carried out
using the software user interface.
The following specific audio ports are available:
Audio 1 to Audio 8 Socket, input/output, mono, line level
Audio Out
AI
AO
Note
If possible you should use the line ports of the intercom for transmitting au-
dio signals on the intercom systems. The following specifications should
be complied with in all cases.
