ALM Busy Circuits Jumble Henge
Four stereo inputs summed to flexible stereo outputs
8 HP Eurorack module
The ALM038 Stereo Sum is a unity gain passive-style summing mixer designed to combine multiple stereo signal pairs into unified outputs. It features four stereo input pairs that can be summed into two independent stereo mix outputs or combined into a single stereo mix, making it an efficient utility for merging outputs from stereo mixers, effects returns, and other stereo sources in a Eurorack system.
Features
- Four stereo input pairs
- Unity gain summing
- Two independent stereo mix outputs
- All four inputs can be combined to a single stereo mix
- Top mixer outputs normalised to bottom mixer section
- DC coupled — accepts audio and CV signals
- Mono signals accepted via normalisation of left to right
- 4HP compact form factor
