Processing
Although the control centre system allows for considerable insertion of external
processing it also embodies more than enough internal high quality processing to
eliminate the need for this, in the interests of simplicity and reduced overall system
size, weight and cost.
Processing components
The processing available is:
• 56 x 12 or 24dB/oct. high pass filters.
• 56 x 6 or 12dB/oct. low pass filters.
• 91 x compressor/limiters with side chain filtering and multiple operating
“signatures”.
• 56 x gates with side chain filtering.
• 64 x 4-band parametric EQs with multiple shelf “modes”.
• 35 x 6-band parametric EQs with hi/lo pass modes.
• 8 assignable 31-band graphic EQs.
• 28 additional 31-band graphic EQs that utilise effects processor digital signal
processing (DSP), reducing the available effects quantity stated below.
• 8 stereo effects processors including Reverbs, Delay, Flange, Phase, Dual (stereo)
Graphic and Pitch Shifter.
Note: More effects are planned to be added in the future, which may include
multi-band compression, dynamic EQ etc.
Input channel processing
Each of the 56 full-function input channels has:
• Analogue and digital gain.
• Phase reverse switch.
• Input delay.
• Swept high pass filter with choice of two filter slopes.
• Swept low pass filter with choice of two filter slopes.
• Frequency-conscious compressor with choice of four compression styles.
• Frequency-conscious noise gate with external side chain.
• Insert point.
• Treble EQ filter with choice of four filter types.
• Parametric hi-mid EQ filter.
• Parametric lo-mid EQ filter.
• Bass EQ filter with choice of four filter types.
• Routing via level controls to 32 mix buses.
• Routing via pan control to left and right master buses.
• Routing to mono master bus.
•Panpot (SIS™).
• Direct output.
