The AUDIOMIXER takes various audio sources through its multiple input channels, either coming from virtual set audio, audio from video I/O card, or media audio and controlled independently, then usually combine them to a lesser number of outputs and sent to final AJA card’s final output. In the image below, you can see the Audio Mixer node having 3 audio channel input pins and 1 output pin. Under the Audio Levels properties, the audio levels for each channel is available for controlling its levels. The lowest level is 0.000 which means the audio is mute and the highest is 1.000 which is full volume. The default level is 0.500, which means all the multi-channels will be audible simultaneously.

By clicking on the Add Pins + on the AUDIO MIXER node will add more channels to the mixer so that you can mix more channels together. Below is an example of multiple audio channels from various sources are connected to the AUDIMIXER node and output to AJACARD 's output node.
