13.8.5 Channel Strip
Channel Strip features three processors in one, including a low-cut filter, dynamics processor,
and three-band parametric EQ. Channel Strip optionally applies automatic gain correction to
the EQ so that the input-signal power matches the output-signal power. Use Channel Strip on
any mono or stereo Track that needs basic channel processing.
The following parameters are available for Channel Strip:
• LC and Freq. Click on the Activate button to engage/disengage the Low Cut filter.
Adjust frequency to change the filter-cutoff frequency.
• Compress. Adjusts the compression amount. Variable from Off to 100%.
Simultaneously adjusts threshold (0 dB to -20 dB) and ratio (2:1 to 10:1).
• Expand. Adjusts the expansion amount. Variable from Off to 100%. Simultaneously
adjusts threshold (-64 dB to -24 dB) and ratio (1.5:1 to 2.5:1).
• Active gain reduction is indicated by red "LED."
• Fast, Medium, Slow. Adjusts the RMS averaging speed, slower speed may reduce
artifacts with some audio material. Default is Medium, and Studio One version 1
presets will open set to Fast.
• Display. Displays low-cut filter and parametric-EQ settings. Click on handles to adjust
gain (up/down) and frequency (left/right).
• Low, Mid, High. Adjusts gain and frequency for each band of the parametric EQ. Each
band has fixed Q.
• Gain. Adjusts the output gain of the Channel Strip. Variable from -12 dB to 12 dB.
o
Auto. Click to engage automatic output-gain setting. This guarantees that a 0 dB
input signal equals a 0 dB output signal.
