To adjust the Drive amount, click on the fader
handle and move it left or right to the desired
setting. The numerical display will indicate
the amplification factor in dB and the tube
graphic’s will “glow” will change to provide an
additional visual indication (i.e., “eye candy”).
Command (Mac)/Control (PC)/Option (Pro
Tools)clicking anywhere in the scale will reset
the Drive value to 0dB
OmniTube
Without OmniTube
engaged, WARM
functions exactly like
a tube preamp, i.e., the
regions of the input
signal that exceed the clipping level (typically
transients) are aected and all other regions
are passed with no change.
With OmniTube on, all regions of the input
signal are subject to tube distortion. To
accomplish this, when you engage OmniTube,
a compressor is inserted into the signal path
after the Input Gain control and before the
tube model. The compressor is set to compress
the signal and then apply sucient makeup
gain to ensure that the Drive control can drive
the entire signal above the clipping level. After
the tube eect is applied to the entire signal,
an inverse gain function restores the signal’s
original dynamics.
The eect of OmniTube is highly dependent
on the character of the input signal, which
tube is selected, and the setting of the Drive
control. Experimentation is the order of the
day.
To toggle OmniTube on or o, simply click on
the OmniTube button. The color of the switch
will change to indicate its current state.
NOTE: Despite the fact that
OmniTube employs a compressor,
it is important to remember that
the final output signal is not compressed and
that the original dynamics are maintained.
If you want to actually compress your
signal, you’ll need a separate compressor
somewhere else in the signal chain.
Output Attenuation
This control applies
attenuation to the
signal after it’s passed
through the tube model.
It is typically used to
ensure that no clipping
occurs as a result of
the gain applied by
the Drive control. As a
starting point, set the
attenuation to 0dB (i.e.,
no attenuation). If the
Clip indicator lights,
apply just enough
attenuation to avoid
the clipping and cause
the output level meter
needle to spend most of
its time in the top two
meter segments. (The
top of the level meter’s
range is 0dB.
To adjust attenuation,
click on and move the
fader to the desired
position. The numeric
display will indicate in
dBs the exact amount of attenuation applied.
Command (Mac)/Control (PC)/Option (Pro
Tools) clicking anywhere in the fader track will
reset the control to its default value of 0dB.
