24dB/oct Filter · 48dB/oct Filter   P-81 / P-82 / P-83 / P-84 / P-85

Features

P-81 P-82 P-83 P-84

Four modes : Lowpass (Maximum Flatness and Phase-Linear), Highpass and THRU 16 selectable points for highresolution control of cutoff frequency Cascade mode enables simple cascade connection to neighboring units Input ground line is floatable, enabling the elimination of induced noise caused by ground loops Model Cut-off frequency range Rolloff P-81 0.1Hz to 1.6kHz 24dB/oct P-82 1Hz to 16kHz P-83 0.1Hz to 1.6kHz 48dB/oct P-84 1Hz to 16kHz
