5.2. Double Channel
The Double Channel configuration is the one we use 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 1973-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.26].
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 button is turned Off. This is not a Dual Mono mode though. 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, and will affect ONLY that channel. 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 and the Stereo Mode button is in
the L/R position.
By default, the plug-in works in Stereo mode (the Stereo Link button is On and the Stereo
Mode button 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 Neve 1073 channels were mono, so, when we are working in Double Channel
configuration it’s like we were using two 1073 channels (except that we have the special
Stereo and Mid/Side modes that we didn't have in the original).
