As the name suggests, Helix DSP ULTRA is something quite different from just another processor with a few more channels. ULTRA is a device that takes DSP equipment to a whole new level and demonstrates Audiotec Fischer's expertise as a pioneer in DSP technology.
Computing power can only be improved by increasing the computing power. The ULTRA features two of the most powerful 64-bit audio signal processors available from Analgo Devices. An incredible 2.4 billion MAC operations per second enable processing of twelve individual channels and a sampling rate of 96 kHz.
The new 32-bit ACO platform enables fast performance on everything but it also does so much more. Key features include signal analysis of OEM audio sources and automatic straightening of the response. This compensates for the input signal distortion often introduced in OEM equipment to compensate for poor quality original speakers.
ULTRA installs seamlessly behind any OEM sound source ADEP.3 circuitry and incredibly wide input sensitivity. The 4-32 volt input sensitivity of the speaker-level input allows installation on the rear of OEM amplifiers in cars where removal from the rear of the player is impossible.
