5.2. Double Channel
The Double Channel configuration is where we can use the plug-in to process stereo tracks.
We don't need to select it, since the plug-in automatically recognizes if the audio track is
mono or stereo, and opens the proper configuration accordingly.
However, the Double Channel configuration doesn't operate exclusively in Stereo mode. In
fact, we have three modes to work with in this configuration. The default one is, of course,
Stereo mode. We can confirm this because the sections are tied between left and right
channels (the Stereo Link button is On). So, when we move a control in the left channel, the
corresponding control in the right channel follows, and vice-versa.
But we can also work in Mid/Side (M/S) mode and in Dual Mono mode.
An audio tool that supports M/S processing (such as the TridA-Pre) creates two separate
processes, one for the Mid channel (the center of the stereo image) and one for the Side
channel (the edges of the stereo image), as we explained before [p.24] .
To work in this mode, we have to adjust the corresponding switch (which is only present
in Double Channel configuration) to the M/S position (by default it is positioned in the L/R
position, for Left/Right, or Stereo mode).
Of course, in this mode, Mid and Side channels work independently, so, any changes we
make on one channel are NOT followed by the other channel, as it happened in L/R mode.
The Stereo Link switch is automatically turned Off. As we said, changes in the channel on
the left (the Mid Channel) affect the way we perceive the sound in the center of the stereo
spectrum, while changes in the channel on the right (the Side channel) affect the way we
perceive sound in the edges of the stereo spectrum.
We also have a third mode, which is Dual Mono. In this mode, each of the two channels
works independently, as if they were mono channels. Therefore, any adjustments we make
on one channel will not be followed by the other. This may seem similar to the behavior of
the M/S mode, but it is different because, in this mode, we are processing each channel in
Mono mode, while in M/S mode the processing done on each channel has influence on the
stereo image.
This mode is activated when the Stereo Link switch is Off (by default it is On), and the Stereo
Mode switch is in the L/R position.
By default, the plug-in works in Stereo mode (the Stereo Link switch is On and the Stereo
Mode switch is in L/R position).
Now, let’s examine each control in Double Channel configuration:
5.2.1. Double Channel EQ Section
The EQ section is basically the same as it is in Single Channel configuration, except that
we have two columns side by side (one for the Left, or Mid, or channel 1 in Dual Mono,
and the other for the Right, or Side, or channel 2 in Dual Mono). So, everything is doubled.
Note that the Trident® A channels were mono, so, when we are working in Double Channel
configuration it’s like we were using two channels of the mixer (and we also have some
special configurations, as we saw).
