MRG Synthesizer - LPFa
Product information "MRG Synthesizer - LPFa"
The MRG LPF variant A is a 18dB + 6db low pass voltage controlled filter based on the AS3320 (clone of the CEM3320).
The main characteristic of the filter is that one of the four poles is pushed farther away from the origin in the complex plane,
creating a slope of 18dB at cutoff with no resonance, and a gentler response towards peak when the resonance is added.
This dramatically changes the tone of the filter, and it creates an unique, acid but bass rich filter that still maintains
that sound clarity that the AS3320 provides with exceptional reliability.
In order to shake things a little bit more, a gain control is added, that reaches saturation pretty soon,
But can also be lowered to further increase the range of this filter.
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.

Manufacturer "MRG Synthesizers"
MRG Synthesizers (mrgsynth) are handmade modules designed by Gianluca Guida in Cambridge, UK.
These modules are the result of my growing interest in music synthesis. MRG modules implement high quality classical building blocks of subtractive analog synthesis, with a focus on simplicity and versatility.
I approach synthesizers as technical instruments to explore that marvellous connection between mathematics and brain that we call music. Being technical instruments, MRG modules are designed to be conceptually simple (i.e., do one thing well), and their panels are meant to be concise, and somewhat dry and rational.
MRG's most common modules are part of the MRG 4HP series, a series of small, narrow but powerful and elegant modules.
