FLUX Pure Expander

Clean Up Your Mix
Pure Expander, capable of anything from mild expansion to hard noise-gating, is a versatile tool for cleaning up spillage from recordings, remove noise or reverb, leakage from drum sessions or microphone bleed. By reducing the gain below threshold, it gives you full control over the material making it easy to tighten up the mix and reduce any unwanted low-lever clutter.

Full control over the processing
In addition to the common controls on a dynamics processor; ratio, attack, release, Pure Expander offers control over the fundamental characteristics of the dynamics processing, all in order to provide full control over the processing even in the most demanding situations.

Features

• Up to 8 channels Input/Output
• Generous -/ 48 dB input/output gain range
• Input/Output gain controls for adjusting the levels before and after processing
• Dry/wet control offering true parallel dynamics processing and for blending some of the original “peak” into the processed signal
• Phase invert of the processed signal
• External side chain support for AAX (Native & DSP) and AU ; in mono and stereo format
• Discrete peak limiter at the very last stage of the processing chain rounding off the peaks in a smooth and musically fashion
• Three release modes are presented; manual, auto, and advanced (with minimum and maximum release values fully adjustable)
• Auto delay function allowing for zero attack times by introducing a delay line in the processed signal
• M/S Width for controlling the stereo width of the processed signal
• Link Channel, provides linked/unlinked processing (in M/S mode)
• True bypass control routing the incoming signal direct to the output for a smooth transition between clean and processed signal
• Side chain section featuring a three-band equalizer to generate frequency sensitive processing
• External side-chain available in AU (Mac OS X) and AAX Native & DSP (Mac OS X & Windows) only
• Input/Output gain controls for adjusting the levels before and after processing.

Control the Stereo width of your mix
To control the actual Stereo width of the mix a built-in MS encoder/decoder is used to split the stereo-signal in its M and S components in order to control the actual stereo width of the mix.
The MS Width Control – Sets the stereo width of the processed signal. A -6 dB value deceases the stereo width. A 6 dB value increases the wideness of the stereo mix but can produce phase issue.
The MS Mode Control – Enables one MS encoding matrix at the input and one MS decoding matrix at the output of the dynamic processing in order to control the stereo width of the mix. When engaged, the side chain is fed by a MS encoded signal that is reflected in the display section. M channel corresponds to the normal left channel. And the S channel corresponds to the normal right channel.

Open up the sound and increase the dynamic impression
Two parameters are provided that are kind of unique to dynamics processing; Dynamics Ratio and Level Independent Detection (L.I.D), using the dynamic range content of the signal and not just the signal levels as standard processors do.

Individual Multichannel Processing
Up to eight channels of simultaneous processing for multichannel surround configuration is provided. The processing can be disengaged on any of the channels leaving the material unprocessed, bypassing the original sound.
When operating on a multi-channel bus all, up to eight in total, channels are processed by default, though the processing can be disengaged for any number of channels leaving the material unprocessed and bypassing the original sound.
By doing this in combination with serial instances the material on any number of channels can be processed with individual settings.

Dual Preset Slots and Parameter Morphing
The built in preset manager and the preset morphing slider, provides instant and intuitive control of all parameters and controls. In a second, with a simple one-click operation, everything is copied from one of the two preset slots to the other, even during playback.
The two Preset/Parameter slots, A and B, can be loaded with two full set of parameters at the same time, and except for only A/B comparing two sets of parameters, the morphing slider will allow to mix them, and to record the morph with the host automation.
