AMSynths AM4023 Lowpass Filter (MOTM)

this is a fully assembled and tested analog aetropolis AM4023 12dB low pass filter module, for MOTM synth systems.

the panel is professionally made in the US, aluminum and powder-coated with a textured finish, then silkscreened. 

the AM4023 is a clone of the ARP 4023 2-pole 12dB low pass filter in the ARP Odyssey. this filter has a smooth behavior and unlike many 4-pole filters, does not attenuate the low end with increased resonance settings. Also, with a shallower cutoff slope, it could be argued that the Odyssey had a brighter sound overall. the filter is good for bass and bright lead sounds, and with modern components it is not noisy. It will self-oscillate at high Q settings and it can shred speakers – so beware! With so many 4-pole filters around, it’s nice to have a 2-pole version for some contrast.

the module is 100mm deep (3-15/16")
