I find this compact mixer actually quite nice, but I am torn on the usefulness of audio section and back.
I wonder who in a live environment with 4 video sources s.gleichen device will still hammer out a reasonable sound. Views like this are the mini mixer (as opposed to the video capabilities) but rather very spartan.
I should Meinng to this mini audio mixer and simply omit to provide all appropriate, an audio input for the Internet coding. The financial benefit is certainly not huge, the control unit would certainly be a little clearer.
On the other hand:
For operation with multiple sources is the audio mixer probably useful back when he was a "follws audio video" realized, so to hear only the sound of the active video source.
