Helix DSP ULTRA
As the name suggests, Helix DSP ULTRA is more than just another processor with a couple more channels. ULTRA is a device that takes DSP devices to a whole new level and demonstrates Audiotec Fischer's expertise as a pioneer in DSP technology.
The only way to improve processing power is to add more processing power. The ULTRA features two of the most powerful 64-bit audio signal processors in the Analog Devices portfolio. An incredible 2.4 billion MAC operations per second enable twelve individual channels of processing and a 96 kHz sampling rate.
The new 32-bit ACO platform enables fast operation in everything, but it also does much more. The most important feature is the analysis of the signal from OEM audio sources and automatic response straightening. This compensates for the input signal distortion that is often done in OEM devices to compensate for poor quality original speakers.
The ULTRA seamlessly integrates with any OEM audio source thanks to the ADEP.3 circuitry and incredibly wide input sensitivity. The 4-32 Volt input sensitivity on the speaker level input allows installation behind OEM amplifiers in cars where removing it from the player is impossible.
