Parameter Description
Value
Range
Tube Drive
Drive
Amount of drive applied.
0–100%
Headroom
Point at which the incoming signal starts to
distort. At lower settings, the signal will distort
even at low volumes. At higher settings, the
signal will remain “clean” at lower or mid-range
volumes and then start distorting when it
becomes very loud
-30.0 – 0.0 dB
Saturation
Amount of saturation applied.
0–100%
Output
Output level of the post-drive audio.
-20.0 – 0 – +20.0 dB
Compressor
Type
Type of compression applied.
Peak, RMS, Opto
Threshold
Signal level after which the compressor will be
applied.
-40.0 – 0.0 dB
Ratio
Amount of compression applied.
1.0:1 – 100:1
Output
Amount of additional output gain for the
compressed signal.
-20.0 – 0 – +20.0 dB
Knee
How gradually the compressor reacts as the
threshold is reached.
Lower values apply a "soft" knee (compression
is applied more slowly as signal approaches the
threshold), and higher values apply a "hard"
knee (compression is immediately applied when
the threshold is reached).
0–100%
Attack Length of time to apply the compression.
10.0 us – 100 ms
Release
Length of time for compressed signal to return
to original level.
10.0 ms – 10.00 s
Low
Sens
Sensitivity
threshold of the compressor for low-
end frequencies.
-12.0 – 0 – +12.0 dB
High Sens
Sensitivity threshold of the compressor for
high-end frequencies.
-12.0 – 0 – +12.0 dB
Expander Threshold Signal
level
below which the expander will
reduce signal.
-40.0 – 0.0 dB
Ratio
Amount of expansion applied.
1:1.0 – 1:100
Range
Set the dynamic range above the threshold
value.
0.0 – 40.0 dB
Output
Output level of the expansion audio.
-20.0 – 0 – +20.0 dB
Attack Length of time to apply the expansion.
10.0 us – 100 ms
Release
Length of time for expanded signal to return to
original level.
10.0 ms – 10.00 s
