Advanced Stuff: A Codec Source With Custom Backfeed - Axia Fusion Installation And User Manual

• US Phone ties the Source Profile to a Telos Call Controller module installed in your Fusion console.
These modules work with all modern Telos multi-line phone systems. Enter the Hybrid number to tell the
fader which hybrid the Source Profile controls.
The final step is to define how you want to handle mix-minus. Fusion (and all Axia consoles) automatically
generates mix-minus (N-1, "clean feed") for each phone caller taken to air. To configure this, you'll scroll to the
Default Backfeed Options box and select the desired audio mix from the Feed to Source dropdown.
Nine different Manual Backfeed mixes plus an Auto smart mode are available.
The default option is Auto. Choosing this option eliminates manual mix-minus building by switching the source
of the mix-minus based on the ON state of the fader the Phone source is loaded to. When the fader is in the OFF
state, the caller hears the off-line PHONE mix. The moment the channel is turned ON, the audio feeding the caller
switches to the Program 1 bus, minus the caller's own audio.
Here are the manual options:
• PGM-1 through PGM-4 feed the caller the output of the selected Program bus, minus their own voice.
AUX A through AUX D feed the caller the output of the selected Aux Send bus, minus their own voice.
•
• PHONE is a mix designed to harmonize with typical, traditional radio operations. A channel is assigned
to the PHONE mix by selecting the fader strips PGM 4 key; the PHONE mix is then created pre-fader and
pre-ON/OFF, so that engaging any PGM 4 button will send the audio of that channel to the phone mix at
Unity gain.
We suggest leaving the selection at its default, Auto, unless special circumstances dictate otherwise. No matter
what you choose here, the board operator can quickly override it and select a different function, using the Options
knob at the top of the fader strip.
When your setup is complete, click the OK button at the bottom of the screen.

Advanced Stuff: A Codec Source With Custom Backfeed

If you've followed along and created a Phone Source Profile as described in the previous section, creating a
Profile for a codec will appear similar (minus the phone hybrid controls, of course). If the codec is bi-directional,
your codec Source Profile will need a Backfeed configuration as well.
The Default Backfeed behavior of the Codec provides a mono sum to both the Left and Right channels on the
return audio or named Backfeed.
However, when the Talkback key on the channel strip the codec is assigned to is pressed by the operator, the
board op's mic audio (pre-fader) is routed to only the left channel; the right channel remains unchanged.
By now, you'll have noticed that, when you begin to create a Source Profile from scratch, all profile types have
either "Disabled" or "Default" displayed in the Feed to Source option field.
