Helix DSP Ultra S 12 Channel
Helix DSP Ultra S 12 Channel
Advanced technology, proven excellence
The HELIX DSP ULTRA S once again defines the benchmark for digital sound processors. Targeted optimizations enhance the already outstanding performance of its predecessor for a sound experience that exceeds even the highest expectations. Audiophile precision and innovative engineering, combined in one device – and of course, completely made in Germany.
Audio performance par excellence
The HELIX DSP ULTRA S stands for the highest standards in audio performance. A newly designed audio signal path reduces the distortion factor to a minimum: at its heart are the renowned AKM Velvet Sound™ 32 Bit AD and DA signal converters and new, high-quality operational amplifiers from the legendary TI / BurrBrown "OPA series" with SoundPlus™ technology, assuring the highest sound quality. With the completely revised analog input stage, the ULTRA S achieves optimum interference immunity, enabling unsurpassed clarity and detail without external influences, even under the most demanding conditions.
