Division 6 CEM3340 VCO Main Board Oscillator PCB

Please note: This includes the PCBs and panel only. Please see the bill of materials on the Division 6 website for a complete list of parts needed.

This Voltage-Controlled Oscillator is based on the Curtis CEM3340 IC. The boards are available fully-assembled or in kit format. Can be used as a standalone board, put in an enclosure, or mounted behind a modular synthesizer panel (a Eurorack-format panel is available from us, or create your own).

Features:

• Square, triangle, and sawtooth waves
• Coarse and fine-tuning controls
• Adjustable 1V/O CV input
• Mod, PW and hard-sync inputs
• Reverse-polarity protected
• Eurorack-style power input
• I/O connections on one edge of board; can be connected to wires or separate control board

Inputs

• 1V/O CV
• Mod CV (AC-coupled)
• PW (Adjusts duty-cycle of square wave up or down)
• Hard-sync
