Manhattan Analog MA35 VCF & VCA Filter Korg MS10 style, Eurorack 2010-2020 - Silver

For sale, one Manhattan Analog MA35 VCF/VCA. I owned two of them like in photo (selling only 1 here!) because in the original Korg MS synths you have LPF and HPF so I bought two to recreate a similar filtering system. One of them is already gone so this announcement is valid for ONE unit. Includes original box.

The MA35 eurorack is an internally-coupled VCF and VCA based largely on the back end of the legendary Korg MS-10. The VCF section is based on the classic Korg35 filter architecture, implemented using discrete transistors rather than the original (and impossible to find) proprietary ICs. It is switchable between Lowpass and Highpass modes of operation, which can either be done manually using the toggle switch or with CV via the "mode" jack. There is also a two-channel audio mixer built in to the input. Modular-level signals will overdrive the inputs as you pass ~12:00 on the dial - stay below this threshold for a smooth, liquid sound or push past it for fuzzy screaming mayhem! The VCA section is based on the MS-10's 'single-transistor' design, which adds distinct color to the sound and is an important part of capturing the spirit of the original.

Care has been taken in the selection of period transistors and opamp chips to keep the character of the sound as authentic as possible. This is not a hi-fi module! It's a little raw and a little noisy - in all of the very best ways.

The MA35 is fully protected from reverse power connection. The proper orientation of the ribbon cable is indicated on the top copper layer of the pcb, just below the power header.
