Product Information
Full details
The Dreadbox Eudemonia is an essential utility module for Eurorack enthusiasts seeking a space-saving, high-quality 3-in-1 signal processor that combines mixing, filtering, and amplification in a single 10HP unit. It is ideal for users who need to consolidate their signal chain into a compact, reliable tool for sound design; however, its specialized filter configuration means it lacks the extreme character of dedicated boutique filters, serving instead as a versatile workhorse for standard patching needs.

Extended Product Information
FAQs
Does the Eudemonia require external power?
Yes, it draws power from your Eurorack case via the included ribbon cable.
Can the HPF resonance be adjusted?
No, the 18dB High Pass Filter on the Eudemonia is non-resonant.
Is the VCA linear or exponential?
The module utilizes an exponential VCA for natural, musical response curves.
How many HP of rack space does it occupy?
The Eudemonia occupies 10HP of rack space.
What is the primary purpose of the LED indicators?
The LEDs provide visual feedback of the current CV sum, helping you monitor modulation depths and signal intensity.
Can I use the Eudemonia to process external line-level signals?
Yes, provided the signals are boosted to Eurorack levels first, or if the mixer gain is sufficient to push the signal to a usable level.
Troubleshooting
No sound output even with signals connected
Check that the VCA CV input is receiving a control signal, as the VCA will remain closed without an envelope or gate.
Audio distortion or clipping
Check the red peak indicator light. If it is blinking, your input signals are exceeding 10Vpp; reduce the gain levels on the 3-channel mixer.
Module LEDs seem unusually dim or unresponsive
Verify that your Eurorack case power supply is not overloaded and is providing sufficient current on the +12V rail.
Pros and Cons
Pros
- Consolidates three distinct functions into a single 10HP module
- Intuitive visual LED feedback for CV and signal levels
- High-quality 24dB LPF provides classic, musical resonance
- Compact depth allows for installation in shallow cases
- Excellent for both audio signals and CV modulation
Cons
- High Pass Filter is fixed and non-resonant
- Shared signal path architecture limits parallel processing capabilities
- Requires careful gain staging to avoid the 10Vpp peak limit
Setup, Compatibility & Care
- Installation: Power down your Eurorack case before connecting the 16-pin ribbon cable to the power distribution board. Ensure the red stripe on the cable aligns with the -12V marking on the module and the bus board.
- Compatibility: The module is fully compatible with standard Eurorack signal levels. It expects audio or CV signals in the range of -5V to +5V, with the peak indicator notifying you if signals exceed 10Vpp.
- Maintenance: To keep your Eudemonia in top condition, ensure the module is not exposed to extreme humidity or dust. If the potentiometers feel gritty, use only specialized electronic contact cleaner designed for analog synth hardware.
- Placement: Given the 35mm depth, it is compatible with most skiff-style cases and portable setups.
