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
