DPA880
Main Features
Maximum Delay:
380.998ms by 21us increment/decrement step, on each
Output
Parametric Equalization:
3 filters on each Input (when selected Line input or Mic without
feedback eliminator active) assignable as Bell or Shelving
5 filters on each Output assignable as Bell or Shelving
Filters:
Symmetrical Bell or High/Low Shelving up to second order
Filter gain:
for Bell and Shelving the gain is ranging from -15dBu up
to +15dBu by 0.5dBu resolution steps
Center frequency:
selectable with a 1/24th of octave resolution steps from
20Hz up to 20kHz
Filter Q/BW:
Q/BW from 0.4/3.59 up to 10/0.0312 by 0.1 resolution steps (Q)
Each Filter of the Eq can be singularly “Bypassed” once set.
