If your StudioLive AR mixer's Control Room and Phones outputs appear to not pass audio,
be sure that an AFL or PFL button is not inadvertently engaged on a channel that is not in use.
The PFL/AFL buttons act as [Solo] buttons for listening to specific input or output channels through the Control Room and Phones outputs of the StudioLive AR.
NOTE: AFL/PFL assignments do not affect the Main L/R XLR Outputs of the StudioLive. These only change what the Control Room and Phones outputs are monitoring.
If none of the AFL/PFL buttons are engaged, the Control Room and Phones outputs will monitor audio from the Main Output.
If a PFL or an AFL button is inadvertently engaged on a channel that does not have input/output (no signal or audio), then the Control Room and Phones outputs would be monitoring that channel with no audio- this would give the impression that these outputs are not passing audio or malfunctioning.
Disengage all active PFL/AFL buttons to be sure your StudioLive's outputs are passing audio from the Main mix.
NOTE: With the StudioLive ARc (USB-C) models, there is an indicator-light on the right side of the console to show if AFL/PFL is engaged (photo below).
PFL stands for Pre-Fader Listen and sends the audio signal of the engaged input channel to the Control Room and Phones outputs of the StudioLive AR. This signal is Pre-fader, meaning the placement of the fader for that channel (with PFL engaged) will not alter the signal sent to the mentioned outputs.
AFL stands for After-Fader Listen and sends the audio signal of the engaged output channel to the Control Room and Phones outputs of the StudioLive AR. This signal is After-fader (Post-fader), so the placement of the fader for the channel (with AFL engaged) will alter the signal sent to the mentioned outputs.
