PFL, AFL AND OUTPUT LISTEN
Brio 36 has comprehensive built-in, after fader listen (AFL), pre fader listen (PFL), and ‘output listen’ (OPL) systems,
allowing you to listen to multiple combined audio feeds at various points in the signal chain.
Multiple paths can be PFL’d, AFL’d or have ‘output listen’ activated at any time to create summed mixes of pre/post fader
path feeds.
AFL
Selecting AFL for any path replaces the current feed to the console monitors with the path’s post fader feed.
AFL provides a ‘non-destructive solo,’ allowing you to quickly check individual paths whilst maintaining all mixes as they
are. Only the monitor output is affected by AFL, no paths are cut and the mix to all other buses is preserved.
PFL
By default, selecting PFL anywhere across the surface feeds the pre fader feed of the path to Brio’s dedicated PFL
speaker output. If PFL TO MON is activated within the monitor pop-up, the PFL feed will replace the monitor source,
as described for AFL above.
Output Listen (OPL)
Mains, auxes and direct outputs all have an OUTPUT LISTEN option. Like AFL, this provides a non-destructive solo,
but output listen takes the feed after the addition of output delay, directly before the feed leaves the console.
PFL Position in Audio Chain
The PFL point may now be placed at the Input, Pre EQ, Post EQ or Pre Fader in the Audio Path. This is accessed from
the Meter & PFL button in the Screen Header. Selections can be made per path, or applied to all Paths. See Figure 1.
