Center Square Music Stereo CEM Filter Rack Modules Featuring Dual Curtis VCF CEM3328




via this auction

"These are single rack space modules consisting of a pair of 24db/oct low pass filters using Curtis CEM3328 synth filter chips. These are great sounding, musical filters with the special feature of consistent volume across resonance settings.

These modules have balanced/unbalanced inputs and unbalanced outputs. There are CV inputs for frequency and resonance on each channel, and a stereo link switch to have the knob settings from channel one operate channel 2 (the CV freq. input also carries over, but the res. CV control jack does not so you need to use a multiple if you want identical CV on the resonance input).

High-quality parts used through-out (Nichicon and Nippon caps, etc). These are professionally designed, assembled, and wired. Uses quality double-sided pcb's.

The only thing I would say is not professional quality are the control decals. I used water-slide decals so they will last and have a low profile, but they don't look nearly as good as proper screen printing or engraving methods in my opinion."
