Audio Input
An external microphone or a line source can be connected to the product’s Audio-in connector. Congure the audio input settings
under Video & Audio > Audio Settings.
Source - Select Microphone for an external microphone or Line for a Line in device, e.g. a n audio mixer for multiple microphones or
a microphone with a built-in amplier.
Microphone power - The E nab le microphone power option provides DC power for an external microphone. Microphone power
should only be used with microphones that have no battery. This setting should not be enabled when using a dynamic or battery
powered microphone. Microphone power will not harm the microphone; if you are uncertain, try switching it off and on. To use a
professional microphone requiring 48V phantom power, you need an external power supply a nd a balanced-unbalanced converter
(audio transformer) in between.
Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to amplify the
sound. I f the sound is too high, choose a lower dB. The Level bar gives a visua l representa tion of the a udio signal level in dB
relative to the full-scale input level.
Green the signal is at a good level.
Yellow the signal is becoming d istorted.
Red the signal is distorted.
Encoding - Select digital audio encoding format.
AAC requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec.
If achieving the best possible audio qua
lity is a priority, AAC is the recommende d codec to use. An AAC licen se
is included in the Axis product.

Sample rate - The number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but
also requires a greater bandwidth.
Bit rate
- Set the required bit rate depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit
rate may have latency or delay, but will require less b andwidth.
