Studioengine Vmix Controls - Axia Element Installation & User Manual

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 also have a VMIX section. This is the
remnants of an earlier implementation of VMIX,
whereing the control was shared between the
Engine and the console. With Element 2.0 soft-
ware, we have begun the process of transition-
ing 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

made to the VMIX take effect as soon as you apply them.
While you wouldn't want to engineer 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
section and a
Virtual Mixer
to the portion later in this chapter). The portions

of this page that display settings on a grey background
are indicators only, not controls. Settings displayed on
white backgrounds are controls, and can be adjusted.
At the top of the page, you can see the name of the
Engine you are logged into. Below are eight submixers,
each with five inputs. All eight submixes are summed
into the VMIX Main. You're probably already thinking
that there are a lot of things you can do with this setup!
Figure 6-1 shows a portion of the VMIX setup found
in the Studio Engine web pages. It shows the first of the
eight Submixes (VMIX 1). Let's look at the controls and
see what they do.

If you need to use this mix, verify that the Channel num-
ber assigned to it is a unique channel number (just as
you would in configuring the channel numbers assigned
to Audio Node streams). When enabled, you can use this
source anywhere in your network.
In most cases, the VMIX Subs are the only channels
you will need to enable. Select the type of Livewire mode
needed for the application (Live, Medium or Standard
Stereo). Provide an appropriate unique channel number
to generate and send a Multicast signal to the network.
Only enable Submixes you intend to actively use; active
submixes without any activity simply clutter up your net-
work with empty streams!
