003: Stereo Expander
On-screen graphic, 003 Stereo Expander
An expander is like the opposite of a compressor: it makes
quiet signals more quiet. You can use this to increase
dynamic range, emphasizing the differences between soft
and loud.
ENVELOPE
This part of the effect allow you to select and listen to the
control signal, adjust the input level of the FX Control
Buses, and select between RMS and Peak detection modes.
The parameters are the same as for the Stereo Compressor;
for more information, see “ENVELOPE” on page 762.
SIDE CHAIN EQ
This multimode filter applies only to the control signal, and
not to the main audio path. Use it to alter the response of the
expander so that it reacts (or does not react) only to specific
frequencies. The parameters are the same as for the Stereo
Compressor; for more information, see “SIDE CHAIN EQ”
on page 763.
EXPANDER
Ratio [1.0:1…10.0:1]
Sets the signal compression ratio.
Threshold [dB] [–40…0]
Sets the level above which the compressor is applied. For
more information, see “Threshold [dB]” on page 763.
Soft Knee Width [dB] [0…30]
Sets the curve at which compression is applied. p.763.
Attack [msec] [0.45…500.0]
Sets the attack time. For more information, see “Attack
[msec]” on page 764.
Release [msec] [5…5000]
Sets the release time. For more information, see “Release
[msec]” on page 764.
Lookahead [Check-box]
Switches level detection look-ahead (expander input delay)
on/off. For more information, see “Lookahead” on page 764.
Gain Adjust [dB] [–Inf, –38…+24]
Sets the output gain.
Source [Off…Tempo]
Selects the modulation source for the output gain.
Amount [–63…+63]
Sets the modulation amount of the output gain.
OUTPUT
This is the standard effects output section, with modulatable
control over wet/dry balance. For more information, see
“OUTPUT” on page 762.
The light gray area shows the Soft Knee Width.
Notice how the slope of the yellow line changes
as it passes through this range.
Please see the description of the Stereo
Compressor for more information on the
graphic display.
The yellow line shows the output level, relative to the input level. This will change according to
the Ratio, Threshold, and Soft Knee Width.
The expander lowers the level when the input signal is below the Threshold, to the left of the
gray area. In the example shown here, a –30 dB input results in –40 dB output, while a -5dB
input passes through unchanged.
