4.5. The 1973-Pre preamp and EQ plug-in
The Arturia 1973-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 1973-Pre EQ and preamp 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 highly praised by audio professionals for
many decades now. 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 1973-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.
The Transformer switch on the right, which allow us to change the type of transformer in
use, will have a slight impact on the kind of induced saturation and harmonic distortion
produced by the plug-in.
After this stage, the signal enters the EQ section, where it will be further transformed by
boosting or cutting groups of frequencies. Besides the three EQ bands, this section also
features a filter 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 on the bottom of the EQ section 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 Channel, as explained below.
