The Erica Synths Black Stereo Mixer V3 is the perfect solution if your system features several modules with stereo inputs or outputs – something that is becoming much more common in Eurorack, especially over the last year or so. For example, Erica Synths BLACK HOLE DSP 2, PICO DSP, BLACK STEREO DELAY etc…and all other modules you can find under our STEREO PROCESSING shop category:

For extra flexibility, the MERGE switches on the first two stereo channels’ inputs allow them to be summed into mono. This would allow for 2 mono inputs to be mixed together at equal levels in the centre if desired (instead of panned left & right). This mono sum is then mixed with the other stereo channels, and could be handy for mixing 2 drum sounds or VCA waves together, where individual control over level is not required. Obviously, you could also run one signal via an attenuator, to allow for separate level adjustment if required.

Erica Synths have designed this module in order to save rack space, and have produced a compact mixer with lot of useful, performance oriented features. This version of the module also features a selectable +6db boost on channels 1 & 2. This could be used to integrate external line level equipment with your modular – or alternatively boost modular signals into overdrive.

For even more functionality there is the BLACK PFL expander module, which adds pre-fade listening for all channels, along with a headphone output. This is compatible with both V2 and V3 versions of the Black STereo Mixer.
