PFL (Input Solo)
When any input’s PFL is activated, the currently selected Headphone Source is replaced with the
signal of the selected input (This signal will be pre- or post-fader depending on the input’s setting
in Setup Menu option INPUTS > Input to ISO Routing). The selected input’s Activity LED flashes
yellow when the input’s PFL is engaged. Additionally, the PFL number will appear in the lower right
corner of the Main Screen.
When Setup Menu option INPUTS > PFL Toggle Mode is set to 6ch (default), entering the Input Set-
tings Screen will also engage PFL for that input. Hold the Select Encoder while sliding Input Select
Switch to display the Input Settings Screen without engaging PFL on the input.
When Setup Menu option INPUTS > PFL Toggle Mode is set to 3ch, the Select Encoder and Input
Select Switch are used together to access inputs 4, 5, and 6 PFL or Input Settings Screens. ( See “PFL
Toggle Mode”, page 25 )
PFL monitoring only affects the headphone monitor; It does not affect audio sent to the outputs or inter-
nal recorder.
