Doepfer A-101-6 6stage Opto Fet Filter hp It houses an 8” wooferA 101 6 is a new filter module that uses so called opto FETs to control the filter frequency. Opto FETs are very similar to Vactrols but use light depending field effect transistors (FETs) instead of light depending resistors (LDRs). A opto FET is a combination of a light depending FET and a LED (light emitting diode) both put into a small light proof case. The advantage compared to vactrols is the much faster response of opto FETs compared to LDRs.
