44. AUX 3/5, AUX 4/6
AUX 3/5 adjusts the level of the channel’s LEFT post-fader signal that is added to either AUX
3 or AUX 5 mix according to the AUX 3/4 – AUX 5/6 switch position. AUX 4/6 adjusts the level
of the channel’s RIGHT post-fader signal that is added to either AUX 4 or AUX 6 mix
according to the AUX 3/4 – AUX 5/6 switch position. Unity gain is at the center detent
position and +10 dB of gain is at the full clockwise position.
45. PFL
The PFL switch connects the channel’s L and R pre-fader signals to the PFL single mix. At
the same time it switches the headphone and control-room outputs from the Master L/R
(main) mix (default) to the PFL. It also connects the PFL signal to the R meter to aid the
setting of the input gain and is not affected by the mute switch position. The (right) PFL meter
will read 0 dB when there are signals present at both L and R channels simultaneously. If
there is only one signal present at either one of the L or R channels the meter will read –6 dB
lower.
VII. MASTER SECTION
46. MASTER GROUP 1—4 FADERS
This smooth 60 mm, logarithmic Group 1—4 mix output
level control sets the levels of the Group1-4 channels sent to the
output connectors (ranges from -97 to +10 dB). The
reference setting for these controls is “0 dB” — unity gain
position.
47. MASTER GROUP 1—4 “R” ASSIGNMENT SWITCH
Each “R” ASSIGNMENT SWITCH assigns the Group post-
fader signal to the Master R channel.
48. MASTER GROUP 1—4 “L” ASSIGNMENT SWITCH
Each “L” ASSIGNMENT SWITCH assigns the Group post-
fader signal to the Master L channel.
49. PFL
The PFL switch connects the Group 1-4 pre-fader signal to
the PFL mix. At the same time it switches the headphone
and control-room outputs from the Master L/R mix (default)
to the PFL. It also connects the PFL signal to the R meter. Depressing any one of the PFL switches
illuminates the corresponding group yellow-LED and simultaneously activates a blinking (1 Hz)
yellow master LED in the master-PFL section.
50. MASTER L/R FADERS
These smooth 60 mm, logarithmic Master L/R mix output level controls
set the levels of the Master L/R channels sent to the output connectors
(ranges from -97 to +10 dB). The reference setting for these controls is
“0 dB” — unity gain position.
51. LED METER
This two-channel, 12-segment LED peak level meter with -33 to +9 dB
range and CLIP indicator (-2 dB below clipping), displays the Master L/R
signal (default). The 0 dB reading corresponds to +4 dBu at the balanced
outputs or 0 dBu at the unbalanced outputs. The R meter is also used with
priority for PFL metering.
