Audio Input
An external microphone or a line source can be connected to the product’s Audio-in connector. Configure the audio input settings
under Video & Audio > Audio Settings.
Note
The internal microphone on this Axis product cannot be used.
Source - Select Microphone for an external microphone or Line for a Line in device, e.g. an audio mixer for multiple microphones or
a microphone with a built-in amplifier.
Microphone power - The Enab le microphone power o ption 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. If the sound is too high, choose a lower dB. The Level bar gives a visual representation of the audio signal level in dB
relative to the full-scale input level.
• Green — the signal is at a good level.
• Yellow — the signal is becoming distorted.
• 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 quality is a priority, A AC is the recommended codec to use. An AAC license
is included in the Axis product.
• G711
• G726
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 b andwidth.
Bit rate - Set the required bit rate depending on the selected encoding. A highe r bit rate will give better audio quality. A lower bit
rate may have latency or delay, but w
ill require less bandwidth.

Audio Output
An external speaker can be connected to the product’s Audio-out connector. The output can be used with high impedance
headphones or connected to another amplifier with speakers.
Configure the audio output settings under Video & Audio > Audio Settings.
Output gain - Control the volume (dB Full Scale) of the line audio output. If the sound is too low, choose a higher dB. If the
sou
nd is too high, choose a lower dB.
