The 4 Series processing platform has been designed to operate at a native sampling rate of 96kHz and also be powerful enough to cope with the additional inputs and outputs. Available on each input channel is a 28 band graphic equalizer, in addition to 8 bands of fully parametric equalization. Each output path features up to 9 parametric sections, in addition to the crossover filters which themselves now offer slopes from 6dB/Octave up to 48dB/Octave.
