Helix DSP 3S 8 Channel
Helix DSP 3S 8 Channel
Refining our standards
The HELIX DSP.3S is our new definition of the standard for digital signal processors. Continuously refined, this 8-channel DSP presents numerous improvements in detail. Besides the obligatory optical digital input, an additional coaxial digital input now provides the best conditions for connecting high-resolution signal sources with a sampling frequency of up to 192 kHz.
Most advanced technology for ultimate High-Res sound experience
The 64 Bit audio DSP of the latest Sigma350 generation and a throughout, native high resolution signal processing with 96 kHz sampling rate as well as A/D and D/A signal converters from BurrBrown provide outstanding sound quality. This makes the DSP.3S perfectly prepared for processing High-Res audio signals with a bandwidth of more than 40 kHz
