Flexible Audio Features
•
The TANDBERG 8000 has a
flexible integrated audio system
, which consists of 6 audio
inputs where any number of audio inputs can be active at the same time.
•
When storing
presets
, all audio settings will be stored together with the selected video
source/camera position.
•
The TANDBERG 8000 has
lip synchronization
for audio.
•
Intelligent Audio Mixing:
Through adaptive weighting, the system establishes one
microphone as active, automatically determined by the user who is speaking. This feature
prevents sounds from inactive microphones or other audio sources from being picked up and
eliminates distracting background noise. Intelligent Audio Mixing leverages the capabilities
of the four separate acoustic echo cancellers.
•
Audio Level Meters.
Measures and displays the audio input level for each audio source
independently, providing an on-screen visual aid to ensure optimum audio performance and
simplifying installation. ‘Centre point mark’- or slightly below- is the preferred value for best
performance.
40 Additional attenuation is possible on Audio Output 1 by using the remote volume control setting.
