Xovers
Range:
Xover 1: Off to 1,6 kHz
Xover 2: Off to 4 kHz
Xover 3: 100 Hz to Off,
Xover 4: 250 Hz to Off
Press this button to access the four cross-over
points between the five-bands. The parameters
are automatically assigned to faders 1 to 4.
Defeat Thresh
Range: -3 to -30 dB
This is a unique control which holds the gain
from the multiband compressor below a certain
threshold. No matter the spectral shaping ap-
plied from multiband system, below the Defeat
Threshold, the frequency response is flat and
gain is unity.
Defeat Threshold is relative to Compressor
Threshold, which is relative to Reference Level.
Defeat Ratio
Range: Off to Infinity
Controls how close to the Defeat Threshold the
make-up gain of the compressor is counter-
acted. At high ratios, the signal only has to be
slightly below the Defeat Threshold before the
compressor gain is fully defeated.
