With the 3:1 MixerAfter Later Audio offers a versatile Unity Mixer for audio and CV signals, which processes signals in level 1:1. The mixer module can sum up to three sources on two strings each or up to six signals on the lower output by omitting the first output. With the rear panel Jumper it is selectable whether the channels work with 1:1 or 1:3 level. Unity Mixer is ideal for merging several drum modules if they have their own level control.
