SoundCraft Five Monitor Series - Manual (Page 43)

FIVE Monitor Functional Description 4.17
The function of the Output SOLO switch is also affected by the GLOBAL MODE
(STE) switch. If the mode is mono, each Output SOLO button switches an equal
feed at unity gain to each of the AFL left and right busses, and a PFL signal to the
PFL bus. If the mode is stereo, the SOLO switches are logic linked as a pair and
the AFL feed is changed to stereo, at unity gain. The PFL feed remains mono.
The SOLO switches can also remotely control a BSS Varicurve™ system - see
page 4.20 for details.

Additional PFL, AFL left and AFL right external inputs, from XLRs on the rearcon,
allow SOLO signals from another console to be added to the Main PFL and AFL
busses. The external PFL level is trimmed by the PFL TRIM pot (see above). When
no solos are active on the console, both PFL and AFL left and right external signals
are monitored by the Headphones and Wedge. The facility would be used when
linking another console as a slave to the FIVE Monitor.
