ADDAC605

The TILT EQ concept was first introduced in the 1970's by Quad Ltd, featured on the company’s model 34 preamplifier.
The tilt control tilts the frequency spectrum of the audio signal by simultaneously boosting the treble and cutting the bass frequencies, or vice versa, making it a simple to use but powerful EQ.

As stated by Quad Ltd, it was designed to produce a very gradual change in balance across the musical spectrum without changing the overall subjective level.
This gradual fall from Bass to Treble, or vice versa, means there’s no sudden change and hence no ‘coloration’ added to the sound, the sound will remain entirely natural but with a slight added bottom or high end. In practice, it rotates most of the audio-range frequency response around a 1Khz axis, so as to change the overall balance of the sound from warm to cool without affecting either the apparent volume or the "colour" of the sound.

Here we introduce this idea into the modular world in a stereo configuration.
CV input with attenuverter was added for the Tilt control as well as a Spectral Motion switch that allows stereo spectral matching or inverted spectrum use of the Tilt control: Left = Right matches both channels direction, i.e. when left channel is tilted to the low end the right channel will also be tilted to the low end 
Left ≠ Right inverts the Right channel spectrum, i.e. when left channel is tilted to the low end the right channel will be inverselly tilted to the high end, or vice-versa.
This possibility is extremely interesting when applied as a stereo effect, in other words, a spectral EQ panner.

DIY Kit for Eurorack Module

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 (see below) for assistance if needed.

Environmental Safety
