The Waveform 1U Headphone mixer module is 8HP and is basically a dual channel passive attenuator utility with a stereo out. Channel 1 is normalled into Channel 2 so that one signal will go to both channels in your headphones when patched into Channel 1. Both channels volume are adjusted separately, and the passive design works well with the high output that most Eurorack modules have. These are pretty easy to build, and the instructions on how to build this can be found on our Build Guide page. Faceplate is black with silver.
PLEASE NOTE THAT THIS IS PASSIVE AND WILL NOT AMPLIFY YOUR SIGNAL BUT WILL ALLOW AN EASY WAY TO GET A HEADPHONE OUTPUT IN YOUR SYSTEM.
