Tube Selector
WARM includes two different tube models.
The Velvet (blue) tube models the subtle
effects 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) effect 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 effect 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 effect 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 effect 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 affect the signal quality).
