Congratulations — you’ve just created your first
Source Profile! You can now bring up your new source
on any Element fader.
Adding Backfeeds and GPIO
to a Source Prole
Since making a mix-minus and mapping contact clo-
sures is often done at the same time a new Source Profile
is constructed, let’s briefly recap those procedures. (De-
tailed setup and operation instructions for your GPIO
Nodes and Audio Nodes are found in their respective
User Manuals.)
Let’s say you’ve connected a hybrid to your Ana-
log Node, named it “Hybrid”, and assigned it a channel
number of 77. You’ve constructed a Source Profile for it,
and you now want to give it a mix-minus backfeed and
set up a GPIO contact closure for the “take” and “drop”
functions. Here’s how:
Make sure that, in your hybrid’s Source Profile, the
Source Type option is set to “Phone” and the Feed
to Source Mode is set to “Auto”. Also set the Back-
feed Enabled/Disabled option to “Enabled”.

Use your Web browser to connect with the Audio
Node you’ll be sending your backfeed to. Choose
Destinations from the main menu to enter the
Destinations screen (Figure 2-3); we’ll set up our-
mix-minus for output #7.
Just to the right of each Channel name box , you’ll
see a “list” icon. Click on the list icon for output #7.
A list of available sources will pop up (Figure 2-4).
Notice that the names and channel numbers of the
sources are both displayed for easy identification.
We’ll choose Hybrid from the list; the list window
closes and you’re returned to the Destinations
screen. The line for output #7 now displays the chan-
nel number and name of the source.
Now comes the step that makes this output a mix-
minus. Each Destination entry line has a drop box
at the end; click on the drop-down and choose To
source.
Automagic: If the hybrid source is loaded to an
Engine and the engine is generating a mix minus
source already, the list box will show TWO iden-
tical channels for the source — but one will have
a description of “TO:” in front of it. Selecting
this source automatically selects TO SOURCE in
the TYPE box.
For a detailed description of these options and
how they operate, please refer to the 8x8 Analog
Node / 8x8 AES Node User’s Manual available at
www.AxiaAudio.com/manuals/ .
Click Apply.
Now point your browser back to your Element Control
Center page and choose GPIO Configuration from
the menu sidebar. (You may also use a GPIO Node
other than the Power Supply/GPIO that shipped with
your Element, just point your browser to that node’s
IP address instead.)
