DOWNMIXES
FIG 2 - CHANGING DOWNMIX DEFAULT SETTINGS
Downmixes are mono or stereo
conversions of surround paths.
Downmixing occurs automatically
whenever a surround signal is routed
on to a mono or stereo bus.
Downmixes ensure that all the required
elements of a surround signal are
maintained and mixed together at
appropriate levels when used to feed non-
surround destinations.
In some circumstances, it may be
preferable not to downmix elements of a
surround path to a certain bus, for example,
if a presenter is being fed a surround
source into their mono earpiece, it may
be beneficial to omit the rear channels to
enhance the clarity of any dialogue in the
front. In this case, the audio should not
be routed from the surround master which
would cause a downmix. Instead, selecting
the surround path on the surface, then
selecting the front L/R (or centre) element
of the surround path from the surround
spill panel mode (if fitted, see the surround
spill section for more details) makes the
front L/R only the currently assigned path
and allows it to be routed on its own to the
required destination.
When a surround path is routed to a mono
or stereo bus from its master, rather than
from a spill leg, a downmix is automatically
applied. Surround to stereo downmixes
maintain stereo separation by mixing front
L, rear L & C together to create a LO - ‘Left
Overall’ channel, and front R, rear R & C
together to create a RO - ‘Right Overall’.
Default downmixes do not include the LFE
channel, but this can be added if required.
The levels that the surround elements mix
together to form a downmix are defined
by the downmix set. Default downmix
values are applied console wide. As well
as the Calrec factory default, operators can
select from 5 other pre-defined downmix
settings to apply to the console from the
>Operate>Spill D-Mix
page of the main
application. Fig 1 on this page shows the
settings in each of the pre-defined sets,
with the currently active downmix set
shown in the first column.
Bypassingthedownmixfaders
When routing a surround path or bus to a
stereo or mono bus, the downmix levels
set by the downmix faders are applied
automatically. To bypass the downmix
faders for a given bus, select the bus in
SENDS-ROUTES mode and press the
BYPASS DOWNMIX FADERS button.
For information on selecting a bus in
SENDS-ROUTES mode, please refer to
the ‘Making a Route’ in this section of this
document.
Pre-faderdownmixes
Should a surround path or bus be sent to
a bus pre-fader, it may be necessary to
have the spill fader levels applied to make
the downmix the same as the post-fader
downmix.
This is because the post-fader downmix
is processed after the spill faders, and so
adjustments to individual legs on the spill
faders will have an effect on the resultant
downmix.
