Virtual Mixing With Vmix; What's It All About - Axia Quasar User Manual

pre-mix up to 5 audio sources each for presentation on a single physical fader (or software fader, if Axia
SoftSurface soft- console software is used). VMix works completely independently of the Fusion
surface. In addition to static control of VMix through its web pages, Axia's Pathfinder routing control
tools can also be used to dynamically control VMix and create mixing functions based on a variety of
system-wide parameters.
VMode (short for Virtual Mode) can be used to convert channel count, channel order, and/or channel
content between audio streams at its input and output. For example, passing some channels while
cutting others, summing stereo to mono, upmixing or downmixing between stereo and multi-channel,
combining channels from two inputs into one output. Select audio as input, define the "Mode"
(conversion type, or in other words, the routing within an internal matrix), and define the output as a
network source into the AoIP network. There are 16 VMode instances in a Fusion engine.

Virtual Mixing with VMix

What's it all about?

In addition to the regular mixing capabilities of your Fusion console, there is an 80-input
"virtual" mixer accessed using the console's HTTP interface (or with PathfinderPC routing tools).
This mixer consists of 80 stereo input channels, a direct output for each channel, 16
submixer outputs, and one master out. The 80 channels are divided equally among the 16 subgroups,
providing 5 stereo channels feeding each subgroup mixer.
The various VMix outputs described above are sources that can feed your Livewire network and
they can be manipulated in the same manner as any other audio source. A VMix source can be
applied to a console fader, assigned to an audio node destination, or monitored by Pathfinder.
To understand this concept, think of VMix as a standalone piece of hardware. If you visualize wiring an
external line mixer to your network, Livewire audio sources would be connected to the mixer inputs; your
VMix outputs then become mixdowns that you can use anywhere else on the network, just like any other
audio source.
To access VMix setup, open a browser on a computer connected to your Axia network and browse to
the IP Address assigned to your PowerStation or StudioEngine or, if you have Axia iProbe, open the UI
page by right- clicking on the device's icon in the left pane. Then, choose the V-Mixer and V-Mode item
from the navigation bar.
The following image is an excerpt of the VMix/VMode setup screen. It shows the VMix Main and Sub-
Mixer 1 controls. These sub-mix controls are duplicated for all 16 VMix submixers.
Note that adjustments made to VMix take effect as soon as you apply them — so changes saved "on the
fly" will affect your output streams immediately.
