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.
Using the Side-Chain Input
Using a Side-Chain Input to TL Aggro lets you
direct audio from another track or hardware in-
put in your Pro Tools session to drive the input
of the TL Aggro compressor. This is usually
achieved by sending the audio from the desired
channel to a bus and setting the side-chain in-
put on TL Aggro to the same bus.
LED Meters, In and Out
On versions of Pro Tools prior to 7.0, RTAS
plug-ins do not provide side-chain process-
ing on TDM systems. Use the TDM version
of TL Aggro if you require side-chain pro-
cessing on a TDM system.
For more information on using Side-Chain
Input, see the Pro Tools Reference Guide.
