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.
