Passive low-pass + high-pass filter in 2HP

RC2 is a passive low-pass + high-pass filter in just 2HP. Two smooth 6 dB/oct filters, one knob each, no power cable – and one signal can give you a dark and a bright version at the same time.

Features

• LP darkens a sound by removing highs, HP thins it by removing lows
• IN HP is normalled to IN LP – patch one source and take a dark and a bright version at once
• Patch OUT LP into IN HP for a simple band-pass
• LP cutoff 0.67 – 17 kHz, HP cutoff 31 – 800 Hz, 6 dB/oct, no resonance
• Fully passive – no power needed

Great for warming up a saw wave, taming noise into wind and sea textures, cleaning the low end of pads, or slow hand-played Berlin School sweeps.

Available assembled, as a DIY kit or as PCB + panel. User manual: bigzun.com
