The lowest field shows the current
routing target
. A mouse click
opens the routing window to select a routing target. The list shows
all activated routings of the current channel by arrows in front of the
listed entries, the current one is shown in bold letters.
An arrow is only shown with an activated routing. A routing is seen
as activated when audio data is sent. As long as the fader is set to
−∞ the current routing will be shown in bold letters, but not have an
arrow in the front.
Trim Gain.
After a click on the
T
-button one channel’s faders are all synchronized. Instead of
changing only a single routing the fader affects all the channel’s active routings. For a better
overview the faders currently not visible are indicated by orange triangles beside the fader path.
When moving the fader the triangles also move to a new position, equalling the faders new
settings.
Note that the fader button is set to the highest routing gain of all routings so that best control is
offered. The gain (fader knob position) of the currently active routing (the submix selected in the
third row) is shown as white triangle.
Background: TotalMix has no fixed channel fader. In case of the Fireface 802
there are 15 stereo Aux sends, shown alternately as single fader within the
channel strip. The high number of Aux sends enables multiple and fully
independent routings.
In some cases it is necessary to synchronize the gain changes of these routings.
An example is the Post fader function, where a change of the singer’s volume shall
be performed identical to the volume change of the signal sent to the reverb
device, so that the reverb level keeps its relation to the original signal. Another
example is the signal of a guitar that is routed to different submixes, means
hardware outputs, which gets much too loud during the solo part, and therefore
needs to be reduced in volume on all outputs simultaneously. After a click on the
Trim button this can be done easily and with a perfect overview.
As all channel’s routings change simultaneously when Trim is active, this mode
basically causes the same behaviour as a trim pot within the input channel,
affecting the signal already before the mixer. That’s how this function got its name.
In the View Options -
Show
the function Trim Gains can be globally switched on and off for all
channels. The global Trim mode is recommended when using TotalMix FX as live mixing desk.
