ACL Variable Sync VCO // precision ramp-core VCO (4 of 4)

Variable Sync VCO by Audiophile Circuits League (a.k.a. ACL) is a precision VCO in the Eurorack modular format. its ramp core is tuned across approximately 4.5 octaves using a ten-turn precision potentiometer with locking scale knob. a three-position range switch bumps the VCO's range up or down by approximately 2 octaves in either direction. FM duties are covered by dual exponential FM inputs and a remarkably stable linear FM input - each with its own attenuator for dialing in precise modulations. in addition a PWM circuit offers classic chorusy pulse modulation, but of course the fun doesn't end there - the unique sync section features a Threshold control and CV input with attenuverter for continuous manual and voltage-controlled scanning across free running, soft sync and hard sync options. 5 independent waveform outputs (ramp, saw, triangle, sine and pulse) give ample voice to your myriad modulations.

this Variable Sync VCO is in very good condition with some rash and minor cosmetic damage near the upper right screw hole as shown. all controls and jacks have been fully tested and work as expected. includes ribbon cable and insured shipping. sold as-described with any returns at buyer's expense and subject to our standard restocking fee.
