HELIX DSP Ultra , 12 Channel High End DSP

  • Entering a new dimensionThe name says it all – the new HELIX DSP ULTRA is anything but another signal processor with just more channels. Rather, it is the next technological milestone that impressively demonstrates Audiotec Fischer's expertise in the field of DSP technology.TwinDSP PowerComputing power can only be replaced by even more computing power – and that's why the DSP ULTRA is equipped with two of the most powerful 64 Bit audio signal processors from Analog Devices. Incredible 2.4 billion MAC operations per second make the twelve separately processed channels and the multitude of new sound features in combination with the high sampling rate of 96 kHz (resulting in an audio bandwidth of over 40 kHz) possible.ACO – Advanced 32 Bit platformRapid processing power not only in the signal path – the particularly fast 32 Bit ACO platform takes over all control tasks and ensures the decisive speed increase, especially for data communication with our DSP PC-Tool software, but also for the lightning-fast switching between up to ten possible sound setups. But ACO offers much more – fantastic sound effects such as Augmented Bass Processing or StageXpander are implemented as well as a channel-separated Input EQ including Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios, which already include a sound setup ex works.
