ADDAC System - 701 VC Oscillator V2
Product information "ADDAC System - 701 VC Oscillator V2"
This is our new VCO; we discontinued our ADDAC701 VCO a few years back and since then we’ve been wanting to release a more stable version with better pitch tracking, increasing pitch reliability, and further minimizing the detuning issues of analog VCO’s.
For this new revision we chose to use the modern version of the CEM3340 ic from CoolAudio and add the triangle to sine circuitry of our previous VCO. This new version is extremely stable over 7 octaves.
We also added a new Mix section which allows mixing of all waveforms controlled by 3 knobs SIN/TRI, MIX and SAW/RECT.
Features:
• Frequency knob with 6 octave range
• Fine Tune knob with 12 semitone range
• Octave switch with 6 octave range
• 1v/octave cv input
• Linear FM cv input with attenuator
• LFO/VCO switch sets overall frequency range
• Soft/Off/Hard Sync switch
• Pulse Width control with initial knob and cv input with attenuator
• SINE, TRIANGLE, SAW and PULSE outputs
• Mix output controlled by 3 knobs SIN/TRI, MIX and SAW/RECT.
DIY-Kit-Type:
SMD-Kit-2. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. It includes SMD and through-hole parts! For build guide, more info, videos etc. please check the buttons below.

Product Safety Information
Eurorack DIY Kits
Important Notice & Intended Use
Please read this safety guide before installation or use. This kit is intended for adult users experienced in electronics and modular synthesis. Assembly, including soldering, is required. Proper testing and installation are essential to ensure safe and functional operation. The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
General Warnings
1. Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.
2. Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.
3. Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.
4. Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.
5. Compatibility:
• This module is designed specifically for Eurorack-compatible systems. Connecting it to non-compatible systems may result in damage or malfunction.
Assembly Requirements
• Soldering skills are required to complete the module.
• Ensure a clean, well-lit and ventilated workspace free of flammable materials during assembly.
• Use appropriate tools and safety equipment, such as eye protection.
Testing
• Test the module thoroughly for shorts or incorrect assembly before powering it in your Eurorack system. When the unit has malfunctions due to incorrect assembly, the entire Eurorack system might be damaged. It's a good idea to test it in a separate case with only that single module.
• Use a multimeter or other appropriate tools to confirm proper functionality.
Installation and Use
• Mount securely in a Eurorack case using the provided screws.
• Use only the included or manufacturer-recommended power cable.
• Connect only when the power is off.
• Follow the module's user guide for instructions on operation. Do not exceed the input/output limits specified.
Responsibility
Users are solely responsible for proper assembly and testing. Contact manufacturer support for assistance if needed.
Environmental Safety
• Dispose of the module, its components, and packaging in accordance with local electronic waste regulations.
Liability Disclaimer
• The manufacturer or distributor is not responsible for any injury, damage, or malfunction resulting from improper installation, use, or modification of this product.
