Axis video server - Audio (AXIS 241QA/SA & AXIS 243SA only)
26
If there are problems with the sound input being too low or high, it is possible to adjust the
input gain for the microphone attached to the AXIS 241QA/SA and AXIS 243SA.
Select the desired audio Encoding format, G711, G726.
Depending on the selected encoding, set the desired Bit rate (audio quality). The settings
depend on the available bandwidth and the required audio quality, i.e. a high bit rate
setting requires more bandwidth.
Audio Output
If the sound from the speaker is too low or high it is possible to adjust the output gain for
the active speaker attached to the Axis video server.
When satisfied with the settings, click Save, or click Reset to revert to the previously saved
settings.
Advanced Audio Settings
The Advanced Quality Settings allows you to tune the audio input to suit your
environment.
Enable speech filter improves the sound quality if using a microphone that is placed close
to the person talking and can also help reduce background noise. The filter cuts the lowest
and the highest frequencies. The bypass frequency range is approximately 250Hz to
3700Hz (measured at -10dB cut-off points).
Enable echo cancellation can reduce the feedback generated when using full duplex. If
sound distortion is encountered, turning echo cancellation off may improve the sound
quality.
