DIY. PCB and Panel only. This is one of our simplest SMD builds with a few 1206 resistors and capacitors and a single 14 pin SOIC.

This is a four channel buffered attenuator and inverter. Zero output is at the center of each control. CCW turns from the center will invert the signal or control voltage input.

• 4 independent buffered channels;
• Attenuate and invert with one control sweep;
• Use what you have! 10k Linear pots are recommended but you can also use log/audio pots;
• SMD parts to save your parts cost;
• Through hole electrolytic capacitors;
• Use TL034 to improve precision and reduce power or use TL074 to reduce costs further;
• 6HP Eurorack with our panel.

If you would like some practice with SMD soldering, we recommend This SMD Beginner's kit and Tutorial or A More Advanced Kit and Tutorial to learn the techniques and sharpen your skills.

This is a low component count project so you can have high quality active multiples in your rack with minimum expense, especially with the low cost SMD parts.

Build it yourself - This is a set of one high quality PCB and front panel ONLY for users who want to purchase their own components and build their own module. Some product photos above show COMPLETED build.

This module will fit perfectly into a 6HP Eurorack space.

Comprehensive manuals, parts lists and component shopping carts are provided in the documentation link for building, testing and using the module.
