Virtual Mixer (VMIX)
What is VMIX?
Virtual Mixer (or VMIX) is a cool feature present in
every Element system whether used with a StudioEngine
or PowerStation. In addition to the foreground mixing
capabilities present on the Element console itself, there
is a 40-input “virtual” mixer accessed via HTTP inter-
face or PathfinderPC software. This mixer consists of 40
stereo input channels, a direct output for each channel, 8
submixer outputs, and one master out. The 40 channels
are divided equally among the 8 subgroups providing 5
stereo channels in each subgroup mixer.
The various VMIX outputs described above will be-
come sources to your Livewire network and they can be
manipulated in the same manner as any other Livewire
audio source. A VMIX source may be applied to an El-
ement fader, assigned to a node destination or simply
monitored by PathfinderPC.
The fundamental concepts of Livewire sources, des-
tinations, inputs and outputs can be confusing to new us-
ers - especially as they apply to VMIX. Here is a review:
• Livewire sources are audio streams that are being de-
livered into your Livewire network.
• Livewire destinations can be physical outputs (that
are connected to external device inputs) or virtual in-
puts to which Livewire audio streams are delivered.
• VMIX Inputs are actually Livewire destinations since
they are virtual inputs to which Livewire streams are
being delivered.
• VMIX outputs are Livewire Sources since they rep-
resent new Livewire streams that are being intro-
duced into our Livewire network.
If you are having trouble with this concept, it may be
helpful to think of the VMIXer as a standalone piece of
hardware. If you visualize wiring an external line mixer
to your network, the Livewire destinations would be con-
nected to the mixer inputs and your mixer outputs would
be connected to node inputs. Your VMIX is “wired” in a
very similar manner.
Constructing Virtual Mixes with
VMIX
The VMIX main mix output provides a mix of all
active inputs, up to the maximum of 40. Each submixer
input includes an on/off setting, a gain setting, and auto-
matic fade-up/fade-down time parameters. The VMIXer
works completely independently of the Element surface
and can be used without an Element if desired. In addi-
tion to static control of VMIX through its web pages,
Axia’s PathfinderPC software can also be used to dy-
namically control VMIX and create mixing functions
based on a variety of system-wide parameters.
StudioEngine VMIX Controls
In an Axia system, all audio processing occurs in the
StudioEngine — the Element console itself does no au-
dio processing. That’s why VMIX settings are found in
the StudioEngine HTTP pages.
You may have noted that the Element HTTP
pages may also have a VMIX section. This is
the remnants of an earlier implementation of
VMIX, wherein the control was shared between
the Engine and the console. With Element 2.0
software, we have begun the process of transi-
tioning to VMIX control on the StudioEngine side
only, but controls are mirrored on the Element
configuration pages to provide a smooth transi-
tion for users upgrading from earlier versions.
This chapter may make reference to the earlier
implementation for clarification reasons.
Even though the “V” in VMIX stands for “virtual”,
you can in fact perform a certain amount of “hands-on”
mixing. Although you don’t have physical control of the
virtual faders or virtual
ON/OFF
switches, adjustments
made to the VMIX take effect as soon as you apply them.
While you may not wish want to operate an entire show
this way, it’s valuable to know that VMIX changes saved
“on the fly” will affect your output streams immediately.
In the HTTP pages of the StudioEngine, there is a
