Chapter 4: TL Aggro 15
Tube Drive
The Tube Drive module adds subtle even order
distortion after the compression processing,
simulating the effect of a vacuum tube ampli-
fier. This provides a difference in the sonic sig-
nature of TL Aggro and is most noticeable on
audio with harmonic content such as piano and
acoustic guitar.
To engage the Tube Drive, turn the Tube Drive
rocker switch to on by clicking it. The Tube
Drive rocker switch and tube light up when
Tube Drive processing is on. The amount of dis-
tortion increases with the output level.
Meters
LED Meters
The LED meters display the peak input and out-
put levels. The LED meters are normalized to
0 dB at digital full-scale.
Note that when TL Aggro is inserted on a mono
track, only the left LED meters will display lev-
els.
Needle Meter
The Needle meter shows input, output, and gain
reduction levels, selectable by the buttons di-
rectly to the left of the meter. By default, the GR
(gain reduction) button is selected and the
meter displays the amount of gain reduction
TL Aggro is applying on the input.
When in GR mode, the needle instantaneously
reacts to peak reductions that occur. The red
scale of the meter indicates compression in dB.
This gives you an accurate representation of the
total amount of gain reduction being applied.
However, the release speed of the needle is lim-
ited to give it more natural motion. At fast re-
lease settings, the instantaneous gain reduction
might be less than what it is presented by the
needle.
In Input (IN) or Output (OUT) mode, the needle
meter displays an average of the signals roughly
approximating the RMS (root-mean-square)
strength of the signal. The grey scale on the
meter represents the input and output levels in
negative dB This gives you a better representa-
tion of the overall loudness of the signal with re-
spect to the LED meters.
