via the listing: "I got this from David Dixon and it was built by himself and from his own system. In perfect shape and I highly doubt you will see anothe of these for sale there are not many iin this format and this was Davids own one he built for himself. It sounds truly amazing. Details as follows:
Dr. OctatureOctal phase shifted outputs Low Pass Filter and VCO/LFO
The intellijel dr. octature, another installment in the David G. Dixon 2164 series of modules.
The basis of the module is a 4-pole lpf inspired by the classic “cascaded ota” design, but realized instead with superior-quality 2164 vcas.
The “octature” refers to the 8 distinct, phase separated outputs (every 45 degrees, or two sets of four 180-degree shifted outputs). each pair has a different slope: 6db, 12db, 18db and 24dB.
The cascaded-stage design is similar to the filter found in absolute classics such as the roland jupiter-6 and sh-101. However, when put into self-oscillation this filter becomes a stable, 1V/Oct tracking LFO/VCO, with each of the 8 outputs giving a sine wave 45 degrees out of phase with the next.
Features:Coarse and fine tuning
Range switch for lfo (0.017Hz to 300Hz) and vco (17Hz to 22kHz) modes
VC resonance with logarithmic response for smooth control
1v/oct temperature stable tracking
Mono/quad resonance gain distribution switch for classic or enhanced performance
Unipolar fm1 and bipolar fm2 attenuated CV inputs
Single pcb design (very shallow/skiff friendly)"
Well, that's a bit disconcerting. I ripped that filter out of my own 5U DIY case and sold it to Mecanikill because I thought he really wanted it. If I'd have known that he was just going to auction it off, I never would have sold it to him.
ReplyDeletePlus, this module has nothing to do with Intellijel or MOTM, and I'm a little upset that I had to find out about this by getting an email from Danjel van Tijn. This is a handbuilt module which is a prototype for the Dr. Octature.
