Koma Elektronik Poltergeist

The Koma Elektronik Poltergeist is a powerful mixer module optimized for use in Eurorack modular synthesizer systems. The module implements the functionality of several different modules into a single ingenious quadrophonic output module, constructed specifically with performance in mind. 

Even at first glance, the Poltergeist’s front panel interface attests to its straightforward, user-friendly orientation. Each of its primary knobs are large and rotate a full 360 degrees for maximum sonic potential. Additionally, the Poltergeist boasts per-channel mute and solo buttons for on-the-fly routing and manipulation. For an even more intuitive live performance, the module affords CV control over each channel’s panning and VCA levels. For those looking for a dedicated, highly capable Eurorack mixer, look no further.
