Macbeth X-Series Dual SV Filter 2010 - Silver

This listing is for an iconic, rare Macbeth X-Series fully analog dual voltage-controlled state variable (SV) filter (VCF) in excellent condition. There’s only some very slight rack rash. Please see pictures. Allways in a smoking free studio with only one owner.

Thanks, but I’m definitely not interested in trades. I’d appreciate it if you refrained from sending me requests for trades.

As you probably already know, Ken Macbeth no longer makes these modules (or no other modules, for that matter). This is a very rare item, hard to come by, and is already becoming a vintage, sought-after instrument. Its value will certainly increase as time passes.

Built solid, to last. No cheap plastic parts here. No cutting corners. Quality is in every single little detail, from the pots to the panel to the jacks.

Note: You can finance the purchase of this item with Affirm, which is now one of the payment options. With Affirm, you have the option to purchase it with 0% financing (if you qualify). I would turn on that option upon request. I would have to apply a 3.1% increase to the price to compensate for additional fee Reverb imposes.

From Macbeth:

Dual Multimode Filter

The Dual SV Filter is a double 12dB/octave state-variable multimode filter which can be used as one or two mono filters or as a stereo filter. The audio input as well as the CV inputs of the left filter are normalized to the according inputs of the right filter which is super practical in stereo use as you omit multiples and a number of patch cords.

Each filter has a switch for inverting the CV - also very interesting when used with one common CV for both filters as you get opposite modulations.

The goal was to design a different sort of filter to compliment the X-Series Backend filter combo (which is 42 hp) but in a smaller space (21 hp). This is the same size as the X-Series single oscillator. The dual voltage controlled state variable filter has a remarkable 'organic' sound and great functionality.

The X-Series Dual SV Filter is a stereo 12db/octave design featuring low pass, band pass and high pass responses. Both sections are manually controlled by a master frequency control. The 'left' side cv input is normalized to the 'right' side cv input. Should two different control voltages be applied to the two CV inputs, each side will react completely separately from each other- and that is where the stereo fun begins!

When it comes to applying an audio signal to the X-Series Dual SV Filter, once again, the left and right audio input sockets are normalized and can be broken by the insertion of another, separate, audio signal being connected to the unit. Attenuated log CV inputs are provided for each filter as well as two separate 1v/octave CV inputs for keyboard tracking, or indeed, any other control voltage.

Both log CV inputs feature inversion switches, which turn any CV input upside down. The sound is amazing when used in stereo with a sample & hold source connected! The duality of these filters allow themselves to be used separately or in series with each other, providing the user with a deeper cutoff slope/frequency...very interesting with two separate resonance controls being applied.

Jumper connectors for each filter are featured on the rear of the unit. They allow standard resonance or self oscillating resonance, which is excellent when used for cross modulation purposes from other synthesizer elements!
