11 EURODESK SX3282 User Manual
In this arrangement you might nd that compression tends to soften the
perceived amount of (especially treble) EQ applied. The solution here is to
apply more EQ. This creates a real ‘pressure’ sound, great for high energy
musicsuch as dance.
In the above example, any aux sends to eects should be applied before
the EQ/dynamics processing takes place. If you want the aux sends to be
post-processing, you will need to address the signal to one of the subgroups and
then insert the EQ/dynamics processor between the corresponding subgroup
output (insert send) and a channel input (insert return).
You can now reclaim the channel 2 input as follows: By applying the channel’s
insert send you can route out an instrument’s signal being plugged into the line
input, treat it with an EQ/dynamics processor, and then reroute it via a subgroup
(insert return) to the master section.
An additional patch enables channel EQ to be placed onto a subgroup with
no reduction in the number of line inputs available, as well as providing an
opportunity to lead a signal pre-EQ into a subgroup. By inserting a plug into the
channel insert socket, the channel is interrupted between the gain pot and the
EQ. A signal which is being led into the channel’s mic-or line input is now guided
into the subgroup inserts input. It appears to be sensible to use this signal path
preferably for readily edited signals (e.g. tape tracks or post-EQ DI-outs from
instruments ampliers), as there is no EQ in the subgroup signal path.

◊ SX3282 insert points are, of course, simultaneously inputs and outputs.
For goodness sake, get them onto a patchbay, where they can appear
as independent sockets, and do away with all these fiddly Y-leads
that always seem to be the first to get knotted in the flightcase
(see section 9 “Patchbay”). Now it is possible to do the incredibly useful
patch shown in fig. 5.3 without having to make up what would amount
to a ring-to-tip, tip-to-ring stereo patch lead.
◊ Insert points may also be used as pre-EQ direct outputs without
interrupting the signal flow. See fig. 7.5 “Direct out connection”.
6. Main Section
6.1 Aux Masters
Aux sends
Much of the main section (situated left and below the bargraph meters) is taken
up by master aux sends and returns.
Stacked in a vertical column are eight master AUX SEND LEVEL pots (51), one for
each bus. Each has a gain structure of -oo to +15 dB. The extra 15 dB of gain
comes in once a knob passes a center detent (representing the ‘normal’ unity gain
position), enabling insensitive outboard FX to be properly driven. Each aux send
has a Solo button (50), and, as with other areas of the mixer, a local Solo light (49),
which starts ashing when any of the aux master sends are solo-ed.
(This is to help you see exactly what has been solo-ed. Any experienced engineer
will have had occasion to painstakingly search through every solo button on
his/ her console trying to nd out why one of the main solo lights was ashing,
whilethe control room monitors remained silent!)
Aux returns
Across from the aux sends are the stereo aux returns. These can be thought of as
eight extra line inputs, congured as four stereo pairs. On these inputs there is up
to 20 dB of gain available. Alternatively, a mono (center-panned) signal may be
returned by plugging into the left aux return jack only.
◊ This feature is disabled if all line-level l/Os from the SX3282 are wired
permanently to a patchbay (see section 9 “Patchbay”).
Aux returns 1 & 2
Aux returns 1 and 2 have full group routing matrices to enable returning FX to
be sent to tape, plus main mix bus assignment. The functions for aux return 1
(mirrored by aux return 2) are: routing-switches (45), Level (47), Balance (48) and
Solo (46). Level controls the amount of signal being blended into the mix or a
group, while balance controls the relative amounts of left and right processed
signal. Be sure to have balance control in center-position, if you’re not actually
working with it.
◊ As always, there are exceptions to the rule above. Some short stereo
delay effects (say 30 ms to left, 50 ms to right) cause a psycho acoustic
effect where the earlier delay seems louder. A similar effect is
noticeable when harmonizing in stereo: a slight pitch shift upwards
will seem louder than one that goes down. In both cases use Balance
(48) to compensate. (An analogy comes from Greece: the columns of the
Parthenon in Athens are slightly bowed so as to appear straight.)
When carrying out the setup mentioned above or any other stereo imaging
exercise, don’t just rely on the control room monitors. Get a pair of headphones
and listen in stereo and in reverse stereo, to allow for any hearing discrepancy
between your ears.
Aux returns 3 & 4
Aux returns 3 and 4 are the poor relations, with only a level pot (44) and Solo
switch (43) each. These are always assigned to the main bus.
Solo
Below the aux returns 1/3 and 2/4 lies a local Solo LED (42). This ashes whenever
a solo button in the column above is pressed.
