Optional Fusion Effects Package:

The Effects package is unprecedented in a portable mixer for location use.  Fusion’s powerful 32-bit floating point DSP provides three-band EQ with peak or shelving filters, notch filters, soft knee compressor, expander and delay on every channel.

A software based effects package ensures there are never any differences, channel to channel, due to passive component ageing. A Fusion will sound as good in 10 years as it does today.
 
All effects are constant delay so a channel with EQ has the same phase and delay as a channel with no EQ selected.

EQ
The Fusion has six filters per channel. The EQ is phase accurate channel-to-channel and totally adjustable.  Shelving and pass band  filters are displayed graphically and sound alike on any channel they are assigned to. EQ filter audio quality and flexibility cannot be equaled with an analog EQ system.  Two notch filters per channel are an excellent tool to remove any periodic noise such as 60/120Hz hums, lighting ballast noise, etc. 

Compressor
A full-featured soft-knee compressor is optional on each input channel and standard on each bus output, this is a total of eight or 16 compressors.  Ratio, Threshold, Attack, Release and Makeup Gain are all controlled separately on each channel.

Expander
The Expander is a great new tool that expands the dynamic range of audio. This function can be used to lower the noise floor of a noisy microphone or recording environment.
