EXPANDER/COMPRESSOR SETUP

Lo Xover

Range: Off, 25, 32, 40, 50, 63, 80Hz ......... 16kHz
Sets the Cross-over frequency between the Lo and Mid Expander/Compressor bands for
the two channels.

Hi Xover

Range: Off, 25, 32, 40, 50, 63, 80Hz ......... 16kHz
Sets the Cross-over frequency between the Mid and the Hi Expander and Compressor
bands for the two channels.

NOTE : The Lo Xover value can not be higher than the Hi Xover.

Crest

Range: Peak, 6, 10, 12, 14, 16, 20, 24, RMS
Select compression method between RMS and PEAK for all three bands. The dB steps
between RMS and Peak are number of dBs needed for a peak-value to override RMS
measurement and can be perceived as a Threshold setting.

Example:
If the Crest parameter is set to 6dB, the Compressor will respond to RMS values and
to peaks 6dB higher than the current RMS value.

Auto Gain

Range: Off/On
Switches the Automatic Make-up gain on or off for the Compressor bands. When set to
on the gain for each band is adjusted according to Threshold and Ratio settings. When
set to off, no automatic gain adjustments are performed

Nominal Delay

Range: 0 to 15ms

<2ms in 0.1ms steps
>2ms in 0.5 ms steps

Sets the nominal Delay of the signal compared to the Sidechain signal. This is also
known as "Look ahead delay", enabling the compressor section to become more
responsive to the incoming signal thereby performing a more precise compression.

Reference Level

Range: -24dBFS to 0dBFS in 0.5dB steps
This parameter sets the reference level in the algorithm.
The reference level is the level at which the Compressor Threshold parameters will
start operating when set to 0dB.
