Hyperoxia + Hypoxia - 0hp / 1U 10hp - passive HPF, LPF and BPF

HPF? LPF? BPF? 10hp? 0hp? Yes.

The Hyperoxia + Hypoxia combines the two popular namesake filters into one unit, giving you access to two independent 1-pole filters (HPF and LPF) or one single 2-pole bandpass filter. 

• Two independent passive filter units, HPF and LPF
• Internal normalization gives you immediate access to the BPF output
• Install in your 1U rail, or use it externally as a 0hp module
• Approximate frequency range (dependent on signal chain): 33 Hz to 33 kHz
• High quality capacitors from Wera
  
• Passive design: no power required

Incidentally, this was also the first module I designed in the hybrid 0hp / 1U format, based on previous 0hp designs. If you own one of the old 0hp designs it's probably going to be worth at least $10 on Reverb. But don't let that dissuade you, maybe one day I will discontinue this one and it will become valuable, too!
