Running a Minimoog Through a Modified Krohn-Hite 3200 Analog Filter

Stevan Dedovic

"Recently purchased a Krohn-Hite 3200 Analog Multifunction Filter off of eBay. This is typically used as a piece of laboratory test equipment. It has been modified to replace the standard BNC connectors on the front with 1/4 inch audio jacks, allowing it to be used as a piece of audio equipment. It's now essentially an oversized analog filter pedal. Here I'm running my Minimoog through the filter, as a little demo.

Below are some new pics of it modded with 1/4 inch jacks from the original BNC connectors.

From the listing:

"I have only seen this quality of construction on military equipment. I slid the sides off to get the pictures. The four Allan Bradly pots that are geared together for frequency selection give a 24db per octave cutoff slope. This could be the finest analog filter of its kind. Selectable Low Pass or High Pass. Low pass is DC coupled for best fidelity. Frequency range 20Hz to 2 Mhz . COMPLETE bench test. This unit is 100%... Complete specs can be found here."
