Channel Strip (Audio Track Effect and AudioSuite)
Channel Strip provides EQ, Dynamics, Filter, and Gain effects. Channel Strip processing
algorithms are based on the award winning Euphonix System 5 console channel strip effects.
The following table lists the Channel Strip plug-in parameters:
Parameter Description
Input Sets the input signal level to the compressor, which, in the 1176 design, determines both the
threshold and amount of peak reduction.
Output Sets output level. Use this control to bring the signal back to unity after applying gain reduction.
Attack Sets the attack time of the compressor. Full counterclockwise is slowest, and full clockwise is
fastest. Attack times vary between 0.4 milliseconds to 5.7 milliseconds.
Release Sets the release time of the compressor. Full counterclockwise is slowest, and full clockwise is
fastest. Attack times vary between 0.06 milliseconds to 1.1 seconds.
n
Setting either the attack or release time too fast generates signal distortion (as it did on the original 1176
compressor). This may or may not be the effect you want to achieve.
Ratio Selects the compression ratio. Available ratios range from 4:1 to 20:1.
You can also Shift-click any one of the Ratio buttons to enable “All Buttons In” mode. The
compression ratio is still only 20:1, but the knee changes drastically and the compressor starts
(mis)behaving a little bit like an expander—watch the meter for details.
Meter Determines how the meter operates.
• GR shows the amount of gain reduction
• –18 and –24 show the output level (calibrated so that 0VU indicates –18dB FS and –24dB
FS respectively)
• Off turns off the meter
Parameter Description
Input
Input Trim The Input Trim control sets the input gain of the plug-in before EQ processing, letting you make
up gain or prevent clipping at the plug-in input stage.
Phase Invert The Phase Invert button at the top of the Input section inverts the phase (polarity) of the input
signal, to help compensate for phase anomalies that can occur either in multi-microphone
environments or because of mis-wired balanced connections.
