Tube Selector
WARM includes two dierent tube models.
The Velvet (blue) tube models the subtle
eects of a classic high-quality tube
preamp. While this model is perfect for
adding warmth to vocals, it’s just as useful
for acoustic guitar, horns, strings, synth
pads, in fact pretty much anything.
The Crunch (red) tube models the deep,
warm distortion of an overdriven tube
amplifier. Use it in moderation to impart
a subtle (or not-so-subtle) eect to
almost any track. Or crank it up for that
“industrial” vocal sound, electric guitar,
bass, or synths.
To select a tube, simply click the
appropriate button.
Drive Amount
The amount of tube saturation eect applied
to your audio is controlled by the Drive control
in combination with the Input Gain control
described above.
The Drive control determines the amplification
factor of the modeled tube pre-amp with the
numeric display indicating the amplification
in dB. At 0 dB , no distortion occurs, even for
full amplitude (+1 or -1) signal levels. These
levels represent the “rails” of the amplifier.
As the Drive is increased, the amplification
is increased. Any regions of the signal that
increase beyond the rails generate saturation
distortion.
Because the maximum Drive amount is +12
dB, generating the tube eect requires the
original signal to be at a level greater than -12
dB. If this is not the case, you should adjust
the Input Gain control to increase the level of
the sound. (Be certain that Input Gain is not
increased so much as to cause clipping.) It may
be necessary to go back and forth between
Drive and Input Gain a few times to get exactly
the eect you want.
NOTE: If your audio was recorded
at an exceptionally low level,
it may be that even maximum
Input Gain and maximum Drive will still not
result in a level high enough to generate
distortion. In that case, either re-record your
audio at a higher level (if possible) or use
your waveform editing program to digitally
increase the level (keeping in mind that this
may negatively aect the signal quality).
