Music Thing Modular - Mikrophonie v3

Product information "Music Thing Modular - Mikrophonie v3"
New and improved version of the classic Mikrophonie contact microphone module. This version incorporates the features of the (now discontinued) Mutable Ears module but allows you to push the preamp into dirtier territory. The kit also includes a choice of 2 x frontpanels allowing the builder to choose whether to have the scratchplate at the top or bottom of the panel.

Tom Whitwell the designer of Mikrophonie describes the original thus:

“Mikrophonie is a microphone preamp with a piezo contact mic built into the panel.

It is an easy way to bring environmental noise and feedback into a modular system, inspired by the early days of electroacoustic music in Paris and Cologne, and by the contact microphone and phonograph cartridge experiments of John Cage, Gordon Mumma, Robert Ashley and Nicholas Collins. Here is a wonderful film from 1966 of Stockhausen & Co performing Mikrophonie 1.

The panel scratchpad has quite a nice rough texture – rubbing it with a finger or a plectrum creates quite a wide range of sounds. The back of the panel is plated and grounded for shielding; the peizo microphone can either be soldered directly to the copper or stuck on with epoxy glue.”

This new version of Mikrophonie improves the amplifier circuit and adds the following features from the Ears version by Emilie Gillet

• An envelope follower, translating the decaying amplitude profile of a tap into an envelope CV.
• A gate detector, translating taps into gate signals.
• The envelope follower and gate detector can process external signals as well as the built in contact mic.

Specs:
• High quality Audio Amp with extended gain range over Ears.
• External input bypassing the built-in contact microphone.
• Envelope follower with 3 preset attack and release times (adjustable by jumper).
• Gate detector with 3 preset sensitivity levels (adjustable by jumper) and +8V gate output.
• Three indicator LEDs for amplifier clipping, envelope follower level and gate detector activity.

This kit contains all parts to build the module, right down to the power cable and the screws. Internal contact mic is included.

The module will work with a range of external contact mics including  DIYed creations made from inexpensive piezo transducers, and off the shelf contact mics. We recommend to use it with LeafAudio's contact mics which are known to be very good.

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 "Music Thing Modular"
Eurorack Modular Synth format. They are designed in Herne Hill, London by Tom Whitwell. I’m a former journalist and magazine editor (Mixmag & The Face). In the noughties I ran the Music Thing blog, before working at The Times. Got into DIY electronics after attending a workshop with Tom Bugs, reading Handmade Electronic Music, playing with Arduino and building guitar pedals. Contacting me directly is rarely a quick way to get help with a project or a technical problem. GitHub issue lists are a good place to start (Turing Machine, Radio Music), a search of MW DIY will often find answers, as will looking at the Facebook Synth DIY group.
