Main Mix Bus
Main Mix Bus
The main stereo mix bus, and all signal combining stages on Control 2802, are optimised for clean summing with high headroom.
Signal Flow - up to 32 Mix Inputs!
The mix bus summing and its output signal ow are illustrated
in the diagram at the bottom of this page.
Signal leaves the console via the balanced male XLR outputs
(MIX O/P L/R) on the rear panel.
The following inputs may be assigned to the main mix:
● Main channel paths 1 to 8 (via channel strip MIX switches).
● Stereo cue bus (via ASSIGN TO MIX - CUE). Use this
option to add the 8 alternative cue input paths to the mix.
● Stereo DAW MIX input (via ASSIGN TO MIX - DAW). This
input is usually fed from the main mix of your DAW, but
could come from any stereo input. There is no input level
control so adjust the output from the connecting device.
● 8-channel SUMMING INPUT (via SUMMING INPUT - MIX).
This can return four stereo, or 8 mono inputs. There is a
single level and balance/pan control for all inputs.
● 2 x stereo FX Returns (via FX RETURN 1 & 2 - MIX).
These can return two stereo inputs. There are level and
balance/pan controls for each stereo input.
● Stereo Mix Insert Return (switched to “parallel sum” mode
as described opposite). There is no input level control so
adjust the output from the connecting device.
Use all these options to mix up to 32 inputs simultaneously!
Mix INSERT
The mix output features a switchable
insert point before the master fader. The
insert send is always active. Thus it is
possible to take a pre-master fader feed
from the insert send.
Engage the IN switch - DOWN - to activate the insert return.
You can now insert outboard devices to apply processing.
The insert send and return are available as balanced 1/4” TRS
jack connectors on the rear panel. If nothing is connected,
then the TRS jacks are normalled. This prevents signal loss if
INSERT IN is accidentally turned on.
Mix INSERT - Parallel Sum Mode
By default, the insert return interrupts the main mix path.
However, if you enable the parallel sum mode, then the insert
return and main mix are combined.
Engage both the IN and SUM switches - DOWN position - the
insert return is now summed with the original mix.
This can be used to subtly enhance or colour the mix via an
outboard EQ or compressor in the insert loop - a technique
known as parallel processing.
Alternatively, the mode can return an extra stereo input to the
mix - connect an input to the mix insert return, and it will be
summed with the main mix bus. (Control the input level by
varying the output from the connecting device).
MIX Output Metering
The LEFT and RIGHT MIX meters are
actually fed from the monitor output (after
the MONITOR SOURCE selector but before
VOLUME, etc). This is often known as
“follow monitor” metering, which allows you
to meter any source, not just the main mix.
As a result, the meters are switched by the
MONITOR SOURCE selector. To meter
the main mix, make sure that the MIX/SRC
switch is assigned to the MIX position:
To guage your headroom, these are peak bargraph meters with
20 large LED segments. They are calibrated to 0VU = +4dBu =
-14dBFS, with 36dB of range. The recessed meter trims can be
used to calibrate the 0VU point.
Master Fader
The master fader controls the level of the stereo
mix output. It is a non-automated, fully passive,
high quality ALPS 100mm stereo linear fader.
There is no gain “in hand”, making it ideal for
fading in and out when laying back the nal mix.
