Delay and Gain:Maximum Delay: 848.998ms by 21us increment/decrement step, on each Input and Output channel. - Spdif input gain(Digital): 0d - Bu on RCA connector. - Parametric Equalization: 7 filters on each input assignable as Bell or Shelving 7 filters on each output assignable as Bell or Shelving. - Filters: Symetrical Bell or High/Low Shelving up to second order. - Filter gain: for Bell and Shelving the gain is ranging from -15d - Bu up to +15d - Bu by 0.5d - Bu resolution steps. - Centre frequency: selectable with a 1/24th of octave resolution steps from 20Hz up to 20kHz.Filter Q/BW: Q from 0.05 up to 3 by 0.05 resolution steps. - High pass and Low Pass Filters. - HPF: from 1st order (Butterworth -6d - B/Oct) up to 8th Order (Butterworth, Linkwitz or Bessel -48d - B/Oct). LPF: from 1st order (Butterworth -6d - B/Oct) up to 8th Order (Butterworth, Linkwitz or Bessel -48d - B/Oct). Filters Cutting Frequency steps: 1/
