Helix DSP Mini MK2


Next generation of the powerful 64 Bit “fixed point” audio miniature DSP, Helix DSP Mini MK2 to provide exceptional sound quality.

The smallest HELIX signal processor gets a worthy successor with the DSP MINI MK2. Like its ancestor, this compact DSP is a real technology package. A powerful 64 Bit audio DSP and BurrBrown converters combined with 96 kHz sampling rate and high resolution audio bandwidth up to over 40 kHz provide exceptional sound quality. The MK2 is also at the top level in terms of measured values – a higher maximum output voltage of 6 Volts, significantly increased signal-to-noise ratio and reduced THD ensure the perfect sound.
Of course, the DSP MINI MK2 is based on the ACO platform with 32 Bit CoProcessor, which not only handles all control tasks with incredible speed, but also enables proprietary sound effects such as Augmented Bass Processing or RealCenter and, last but not least, a channel-separated Input EQ including Input Signal Analyzer (ISA).
