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 outputs 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

Socket, output, stereo, line level

AI

Terminal connector, input, mono, speaking level

AO

Terminal connector, output, mono, speaking level

Note
