Configure the Studio Speakers
Next, manually configure the studio speakers. Since any Studio Speaker is not configured,
go to Settings – Monitor Matrix and choose "2" for "Studio Speaker 1" so a stereo Studio
Speaker output is created.
Studio Speaker outputs are used to automatically mute themselves when Cough Mute is
turned on. If you do not use this function, you don't need to create Studio Speaker
outputs.
Next, go to Patch – Output Patch. Click on Source 5 of Dante Out, mouse over Monitor
Matrix Out and choose "STU 1 – L". Similarly, choose "STU 1 – R" for Source 6 (we have
patched those channels to Nuage I/O Dante Input channels earlier on the Dante Controller).
