10.0 Solo System
10.1 Solo Modes
“The BOX” has three solo modes as explained below:
PFL (Pre-Fader-Listen)
Pre-Fader-Listen (PFL) is a mono, non-destructive solo mode. PFL is the default solo
mode and is enabled when the AFL and SIP switches are not engaged.
When PFL is the current solo mode and a SOLO switch is engaged on a channel or
master, the pre-fader signal is routed to the mono PFL solo bus. The output of the solo
master replaces the current control room monitor source and the soloed audio is heard
in the loudspeakers in mono. The program bus outputs are unaffected when a PFL solo
is engaged (non-destructive).
Since the PFL solo bus is fed pre-fader, the level of the soloed channel may be louder
or softer than the unsoloed level since the fader attenuation/gain is not applied. The
overall solo level is controlled with the solo TRIM pot.
AFL (After-Fader-Listen)
When AFL is the current solo mode and a SOLO switch is engaged on a channel or
master, the post-fader (post-pan-pot) signal is routed to the stereo AFL solo bus. The
output of the solo master replaces the current control room monitor source and the
“The BOX” is equipped with a fully featured solo system that allows
the engineer to isolate exactly what needs to be heard in three
different ways:
•
PFL: Pre-Fader-Listen (default solo mode)
•
AFL: After-Fader-Listen
•
SIP: Solo-In-Place
The solo system has the following components:
•
Channel and master solo switches
•
Stereo AFL solo bus
•
Mono PFL solo bus
•
Solo master
SOLO switches on the input channels and summing inputs activate
the current solo mode. AFL SOLO switches on the aux/cue masters
also activate the current solo mode, but are useful only when the
console is in PFL or AFL solo modes. Refer to sections 7.1.1 and 8.1.1
for additional information.
After-Fader-Listen (AFL) is a stereo, non-destructive solo mode. AFL
is active when the AFL switch is engaged and the SIP switch is not.
AFL solo can be activated from input channels, summing inputs, and
the aux/cue masters.
