Description

Edit description

The KOMA Elektronik Poltergeist Analog Quadraphonic Audio Mixer / Panner / VCA is unlike any other eurorack module that has previously existed. Previously you would need multiple modules from various manufacturers to achieve something similar to what we perceive as quadraphonic sound. But now with one single module, you can mix and control signals quadraphonically with complete control and beyond. Four channels each with it’s own VCA, plus a stereo auxiliary input, are mixed out to four separate outputs enabling the user to manipulate signals both stereophonically and quadraphonically in entirely new and ghostly ways with its 21 ins and outs, 48 analog SSM VCAs and unique hands-on mixing features.

With performance in mind when designing the Poltergeist, KOMA Elektronik included large Pan knobs for total control over the 360 degree range field. Also, clickless solo and mute buttons allow for effortless and instantaneous changes on the fly. Beyond these controls, you can also tailor your sound with extreme detail using functions such as Slope, Field and Origin. With just this mixer, some audio sources and a couple of LFOs, extremely complex sound design can be achieved.

Critic Reviews

Koma Elektronik has officially released the Poltergeist Quadraphonic Audio Eurorack mixer

futuremusic.com

Koma Elektronik's Poltergeist Quadraphonic Eurorack mixer brings a revolutionary approach to audio mixing with its extensive control options and the ability to manipulate multiple signals with ease. Featuring impressive specs like 48 SSM VCAs and a staggering 21 ins and outs, it caters to both quadraphonic and stereophonic needs seamlessly. However, its hefty price tag of $850 may deter some potential buyers. While the innovative design and performance capabilities are commendable, the cost could be seen as a barrier for those looking for more affordable solutions in the Eurorack market. Overall, the Poltergeist is a stellar choice for serious sound designers, but budget-conscious musicians might want to explore alternatives.
