When Livewire inputs are activated, the analog/AES inputs are switched off. However, should LW inputs fail, analog/AES will automatically be
On the output side, both analog/AES and Livewire can be simultaneously active.

If the levels are too high, hybrid performance will be significantly diminished and leakage may occur.
♦♦ First set the Nominal In Level in the Audio menu to a nominal level close to that used in your facility (i.e.
♦♦ You should see the audio from the phone line on the Output LED bargraphs.
