5-BAND PAGE
Xovers
Press this button to access the four cross-over
points between the five-bands. The parameters
are Automatically assigned to faders 1-4.
Parameter range:
Xover 1: Off to 1.6kHz
Xover 2: Off to 4kHz
Xover 3: 100Hz to Off
Xover 4: 250Hz to Off
Defeat Thresh
Range: -3 to -30dB
This is a unique control which defeats gain from
the multiband compressor below a certain
threshold. No matter the spectral shaping
applied 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
counteracted. At high ratios, the signal only has
to be slightly below the Defeat Threshold before
the compressor gain is fully defeated.
Thresholds A & B
Parameter range: -25 to 20dB
Press this button to access the five individual
band Thresholds and the overall All Threshold.
Threshold relative to Reference Level is
set at the Main page.
Gain
Parameter range: 0 to 18dB
Press this button to access the five individual
band Gains and the overall All Gain.
DXP Mode - introduction
The 5-band section is either in normal
compression mode, or DXP mode. Instead of
attenuating signals above a certain threshold,
DXP mode (Detail Expansion) lifts up signals
below the Threshold; thereby bringing out
details rather than squashing the loud parts.
DXP mode therefore is capable of adding
intelligibility and air to speech, lifting harmonics,
or emphasizing ambience without increasing
overall peak level.
As shown on the illustration, gain is positive
below threshold, unity at Threshold, and the
effect decreases above Threshold. In DXP
mode, Ratio becomes Steer. Steer can be
regarded as an adaptive Ratio that gradually
approaches 1:1 above the threshold.
Multiband DXP
DXP mode can be used with any number of
bands up to 5. When used, multiband it is
particularly effective in bringing out air and
clarity.
The processor can act as an automatic EQ that
removes a boost when it's not needed: At very
low levels, where noise is dominant, and at
loud levels where sibilance would become a
problem. Besides from being effective on
speech, DXP mode can be used in mastering
to bring up low levels, e.g. when preparing film
or concerts for domestic or noisy environment
listening.
