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, isn’t. 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.
