SUBGROUPS: (56 through 60)
56. AIR
AIR is a high frequency peaking EQ cen-
tered at 16kHz. Turned fully up, these controls
provide 10dB of boost and fully down effec-
tively bypasses the circuit. Use AIR to provide a
crystalline effect to subgroups, helping them
stand out in the overall mix.
57. SOLO
Engaging this switch isolates the associated
signal and sends it to the control room, phones
and meters. See RUDE SOLO LIGHT (61) and
MODE (63) for more information.
Note: To solo a subgroup in AFL mode, L/R
ASSIGN (59) must be engaged.
58. PAN
When a mono subgroup signal is assigned to
the main mix via L/R ASSIGN (59), it effec-
tively becomes another channel signal and can
be panned from left to right. This knob then
adjusts the amount of signal sent, left versus
right, to the MAIN OUTS (12) (16).
The mixer’s pan circuits employ a design
called “constant loudness.” As the knob is ro-
tated from left to center to right, the sound will
remain at the same apparent volume. To attain
this, both sides of the signal must dip down
about 4 dB when panned center, to account for
the “doubling” of the signal.
59. L/R ASSIGN
This switch allows a subgroup signal to be
sent to the main mix. Engaging this switch will
not interrupt signal at the SUB OUTS (8) jack.
For live sound, subgroups allow a group of
channels to be controlled by one or two sub-
group faders, and then sent to the main mix
using this switch and its associated PAN (58)
control.
For multi-track recording, subgroups can be
used to route groups of channels to specific
tracks of a multi-track recorder via the SUB
OUTS (8). In this case, L/R ASSIGN should not
be used.
