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
Outputs
- Square / pulse wave
- Triangle wave
- Sawtooth wave
Controls
- Power supply: +/- 12V to 15 VDC
- Power connection: Eurorack 10-pin shrouded header (Can hook wires to pin holes instead if not building for Eurorack)
- Current draw: 9mA (+12V) / 6mA (-12V) / 0mA (+5)
- Dimensions, main board: 50mm x 60mm
- Eurorack HP: 4
