Turning the Attack and Release knobs clockwise
increases the reaction speed of the compressor.
1 is the slowest setting and 10 is the fastest set-
ting.
Post Gain
The Post Gain control lets you make up for the
signal gain lost through compression. The val-
ues indicated on the knob are in dB. At maxi-
mum setting, 36 dB of gain can be applied to the
compressed signal.
TL Aggro Bass Compensation
Controls
The Bass Compensation section of TL Aggro af-
fects the compressor’s side-chain circuitry. By
default, Bass Compensation is enabled as indi-
cated by the illuminated green light. To disable,
toggle the switch in the section by clicking it.
The green lamp will turn off to indicate that
Bass Compensation has been switched out of the
side-chain signal path.
When Bass Compensation is enabled, the com-
pressor becomes less sensitive to bass frequen-
cies in the input signal. This models the sensi-
tivity of the human ear, which is also much less
sensitive to low frequencies. For most signal
sources, enabling Bass Compensation will re-
duce the total amount of gain reduction that
TL Aggro induces, but the result will often be
more natural sounding with less pumping and
breathing. For example, Bass Compensation
sounds great on bass guitar or when you have
TL Aggro on your master fader as stereo bus
compressor.
Additionally, TL Aggro provides a cutoff fre-
quency control to tailor the sound of the bass
compensation. This acts as a high pass filter and
the values indicated above the Bass Compensa-
tion slider are in Hertz. As the slider increases
from left to right, the compressor will be even
less reactive to low frequencies.
For example, place a stereo TL Aggro on a full
stereo drum mix. Set the compressor for moder-
ate to high gain reduction levels, enable the Bass
Compensation, and slide the frequency control
from left to right. As the cutoff frequency is in-
creased, you will hear more and more of the kick
drum “punch” through the mix and become
louder relative to snare or cymbals.
TL Aggro Tube Drive Control
The Tube Drive module adds subtle even order
distortion after the compression processing,
simulating the effect of a vacuum tube amplifier.
This provides a difference in the sonic signature
of TL Aggro and is most noticeable on audio
with harmonic content such as piano and acous-
tic guitar.
