Timo Rozendal – 3394 Voice
Product number:
100933
Product information "Timo Rozendal – 3394 Voice"
The 3394 Voice is a compact and flexible analog synth voice that packs a full signal chain into one module.
VCO, VCF, VCA, envelopes, and noise. Based on the classic 3394 chip, it delivers rich analog tone with selectable square, saw, and triangle waveforms, routed through a juicy 24dB low-pass filter capable of self-resonance and pitch tracking. Two built-in envelopes shape both filter and amplitude, with switchable AD/AR modes for dynamic control. When unpatched, it acts as a constant VCO output, and the mix trimmer allows tonal variation by blending in a square sub, noise, or external signal. Ideal for melodic lines or snappy percussive sounds like kicks, snares, and zaps, the 3394 Voice is both a complete voice and a set of standalone building blocks for your Eurorack system.
Features:
• VCO with Triangle/Square/Saw waves
• Lowpass resonant 24db filter
• Square sub oscillator
• Analog noise source
• Built in VCA and 2 envelopes
• Can also be used as separate Filter/VCO/VCA/Noise source
DIY-Kit-Type:
SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder. 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.
