Vostok Instruments - Sigma

Product information "Vostok Instruments - Sigma"

Sigma is a four-channel gate processor for creating variations on clocks, triggers and rhythmic patterns. Each channel adjusts gate length manually or by CV, from 1 ms to 10 seconds, with an additional mode for indefinitely sustained gates.

Four main outputs and four inverted outputs feed a wider rhythm-processing system with 15 additional logic outputs. AND, NAND, OR, NOR and XOR operations act on the length-processed signals, so changing gate duration also changes the resulting patterns. A digital length-processing core and analog logic circuits generate up to 23 simultaneous gate signals from four inputs.

Features:
• Four gate-length processors with manual and CV control
• 1 ms to 10 s gate length plus infinite mode
• Four main outputs and four NOT outputs
• 15 logic outputs: AND, NAND, OR, NOR and XOR
• Logic processing follows gate-length adjustment
• Input impedance: 100 kΩ; output impedance: 1 kΩ
• Length CV range and output level: 5 Vp-p
• Depth: 30 mm including power cable

Product Safety Information

Please read this safety guide before installation or use.

Important Notice & Intended 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.
• Use outside this scope may result in malfunction, damage, or safety risks.

General Warnings

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.

Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.

Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.

Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.

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.
