8 Expander Noise Red (MS) MD3
Multiband expander with look-ahead capability and separate processing of the M and S
components of a stereo signal. This preset offers more control than #7 and #9, when noise
reduction is performed on a stereo source.

9 Cat43 Emulate MD3
Multiband expander emulating processing and operation of the old Dolby Cat43. While
originally designed to align analog noise reduction, the Cat43 is still used for dialog clean-up.
Compare against preset 11-5-9, or for multichannel 10-8-9.
This digital version offers look-ahead capability plus much lower distortion than what’s
possible in the analog world. The fader layout on Icon almost makes you want to paint it
orange for a true retro experience.

Engine Bank F9, decade 4: Multiband Dynamics (MD4)
0 MD4 CD Master MD4
Five band Compressor with integrated Eq and upsampled, adaptive BrickWall 2 Limiter. The
preset provides a spectrally linear starting point for further adjustments. A reference tone at -
20 dB will be subjected to a 3 dB increase in level, which may be easily adjusted on the Trim
fader.
Soft Clip at the Limiter is relative to the Limiter threshold, and the Profile of the Limiter may
be adjusted for a particular type of operation. See details in the description of BrickWall 2
presets, Engine Bank F10, decade 2.
