4.5. The TridA-Pre preamp and EQ plug-in
The Arturia TridA-Pre plug-in is both a preamp and an EQ. This means that it works not only
as an amplifier section, which induces a natural and pleasant saturation to the sound, but
also has an equalizer to further sculpt the spectrum content.
That said, if we are going to use the TridA-Pre preamp and EQ plug-in, we must be aware
that this is a device with a strong coloration, and that is its main strength. More than an EQ,
of which we may have better and more precise units available, this plug-in is justified by
the changes it makes in the timbre, which have been considered for almost four decades as
very musical. So, although it is still considered a very musical EQ, the main reason to use it
will be the desire to achieve the sound of a classic.
4.5.1. Signal Flow
The signal flow of the TridA-Pre follows the logical path for this type of devices. Therefore,
the audio enters through the preamp section, controlled by the Input Gain knobs. This
section adds saturation and harmonic distortion to the signal.
After this stage, the signal enters the EQ section, where it will be further transformed by
boosting or cutting groups of frequencies. Besides the four EQ bands, this section also
features two groups of filters, one to cut the upper high frequencies (Low Pass) and another
to cut the lower range of frequencies (High Pass).
The signal is then directed to the main output, where we have the Output Trim knobs to
control the final level.
There is a switch to invert the phase of the audio (globally), and another that allows
bypassing the EQ section.
Stereo Link and Stereo Mode are two global switches that affect the way signal is routed
and processed when in Double Mode, as explained below.
