Expander
Pressing Threshold, Range, Ratio, Attack and Release keys will immediately assign Lo,
Mid, Hi and Master values for these parameters to Faders 1-4. Press the L/R key to
see all parameters at the same time.
Threshold parameters
Range: -50dB to 0dB (in 0.5dB steps)
When the signal drops below the set Threshold point the Expander is activated.
Range
Range: -40dB to 0dB in 0.5dB steps
The Range parameter sets the Max attenuation relative to the Ref level setting.
Example: With a Ref Level setting of -6 dB and Range set to -10 the max attenuation
can be -16dB.
Ratio parameters
Range: Off to Infinity
The Ratio of the Gain Reduction.
Example: If the signal drops 1 dB below the Threshold with a Ratio set to 1:3 the
actual attenuation will be 3dB.
