The Northern Light Modular Polemixing Filter Model hPF is an h-series dual-channel multimode filter inspired by classics from Roland, Sequential and Oberheim featuring 15 different poles.

The Northern Light Modular Polemixing Filter Model hPF can be used as two different filters, in parallel or even in series, offering a wide range of options. An 8-position buffered rotary switch allows for the creation of a super-strong 7-pole low-pass filter or gentle notch and phase combos. Both cut-off and resonance can be controlled via CV

The h-Series is half the height of a 1U 200 Series module and requires an h bracket to be mounted in a 1U space. Two h modules can be mounted in a 1U space.
