6.5 PFL/SOLO
Fig. 6.6: Solo section
6.5.1 PFL
Pressing S95 disengages the stereo SOLO bus, and replaces it with a separate mono PFL (Pre-Fader-Listen)
bus. Now anything at all which is SOLOed, isnt. It is PFLed instead. PFL should be used for gain-setting. (See
also the essential section 13 Start-up.)
6.5.1 SOLO
SOLO is short for SOLO IN PLACE, and is the preferred method for auditioning an isolated signal or a group of
signals. Whenever a SOLO button is pressed, all unselected channels are muted in the monitors. Stereo
panning is maintained. The SOLO bus is derived from the output of the channel PANs, aux send/return pots,
etc., and is always post fader.
In addition to any local solo LEDs which might be activated, the ultra-bright MAIN SOLO LED (L95) illuminates
whenever anything is SOLO/PFLed. P94 controls the master SOLO/PFL level. Set to unity gain (center
detente), this will match the mix level.
