Powerful 64 Bit Audio DSP With Cutting-Edge DA & AD Converters And Native Resolution Of 32 Bit

High Resolution audio at its best!

Thanks to numerous improvements, the new HELIX DSP PRO MK2 raises the bar to a new level, and not just in terms of sound quality.

Besides the extremely powerful 64 Bit Audio DSP, cutting-edge DA and AD converters, the incredible native resolution of 32 Bit will ensure unparalleled sound characteristics. The improved internal power supply as well as the increased maximum output voltage of 8 Volts contribute to the enhanced sound quality of this stunning processor.

HELIX DSP PRO MK2 provides a HELIX Extension Card slot (HEC slot). This allows adding further interfaces, such as the Bluetooth Audio Streaming module or the High Resolution Audio USB soundcard.
