Digital High-Res 10-channel signal processor with 96 kHz / 32 Bit signal path

SKU: HELIX DSP PRO MK2 Categories: , ,


High Resolution audio at its best!

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

Besides the extremely powerful 64 Bit Audio DSP, cutting-edge DA and AD converters with an incredible native resolution of 32 Bit 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.
Further innovations like the ADEP circuit (Advanced Diagnostics Error Protection) in the highlevel input for circumventing factory-made loudspeaker diagnostic systems, the “Auto Remote” switch for activating / deactivating the automatic turn-on feature of the highlevel input and the software-controlled switch between the optical and coaxial input have been added.

Of course, the HELIX DSP PRO MK2 provides a HELIX Extension Card slot (HEC slot). This allows adding further interfaces like a Bluetooth® Audio Streaming module or a High Resolution Audio USB soundcard. In terms of design, the DSP PRO MK2 shows up with the HELIX-like clean look and offers perfect preconditions for a fast and simple integration.

But not only the hardware has been improved – the software as well has been completely revised. Features like the allpass filter option, the increased adjustment range of the time alignment and the switchable sound options of the DA converters are solely a few examples. Despite its extended feature set the configuration of the DSP couldn’t be easier thanks to the new DSP PC-Tool V4, which leaves nothing to be desired due to its numerous sound optimization options.

No doubt – the HELIX DSP PRO MK2 will again make dreams of the most ambitious sound enthusiasts come true – that´s a safe bet!
