Monitor section
In this section you can select the signal that will be
monitored from the MONITOR OUT jacks and the
PHONES jacks.

Monitor signal priority order

There is a priority order for the signals that can be
selected as monitor sources. While a higher priority
signal is being monitored, it is not possible to moni-
tor signals of a lower priority. Multiple monitor
sources can be selected simultaneously if they are all
of the same priority level.
The priority order of the various monitor sources is
shown below.
Priority order 1
• Pre-fader signal of a monaural input channel
(PFL switch)
• Pre-fader signal of a stereo input channel
(PFL switch)
When a PFL switch is turned on, the pre-fader signal
of that input channel can be monitored from the
MONITOR OUT/PHONES jacks.
Priority order 2
• Pre/post-fader signals of the AUX 1–6 section
(AFL switch)
• Pre/post-fader signals of the A7/G1–A14/G8 sec-
tion (AFL switch)
• Pre/post-fader signals of the G1/A7–G8/A14 sec-
tion (AFL switch)
• Pre/post-fader signals of the STEREO section
(AFL switch)
• Pre/post-fader signals of the MONO/C section
(AFL switch)
• Pre/post-fader signals of the matrix section
(AFL switch)
When a AFL switch of one of these sections is turned
on, the pre/post-fader signal of the corresponding
section can be monitored from the MONITOR OUT/
PHONES jacks.
Priority order 3
• ST OUT (L, R, MONO/C) output signals
If all PFL and AFL switches of priority orders 1 and 2
are off, the ST OUT (L, R, MONO/C) output signal
can be monitored from MONITOR OUT L, R, and
MONO/C.
The PHONES jack will monitor the ST OUT (L/R)
output signal.

AINPUT indicator

If even one of the input channel PFL switches are on,
this indicator will light. When this indicator is lit, you
are monitoring a signal of priority order 1.
BMASTER indicator
If even one of the AFL switches of the GROUP/AUX
master section, the stereo/monaural master section,
or the matrix section are on, this indicator will light.
In this case if the INPUT indicator (1) is dark, you
are monitoring the pre/post-fader signal from one of
the sections (priority order 2).
CMASTER PFL switch
If this switch is on ( ), the MONITOR MASTER
PFL signals (pre-fader signals of priority order 2) can
be monitored from the MONITOR OUT/PHONES
jacks. If this switch is off ( ), the MONITOR MAS-
TER AFL signals (after-fader signals of priority order
2) can be monitored from the MONITOR OUT/
PHONES jacks.
