AUDIOTEC FISCHER

The DSP ULTRA contains two of the most powerful 64-bit audio signal processors from Analog Devices with the outstanding overall calculating power of 2.4 billion MAC operations per second. The Twin DSP Power concept makes the twelve separately processed channels and the numerous new sound features in combination with the extended sampling rate of 96kHz possible.

The DSP ULTRA uses one premium A/D converter: AK5558 and two D/A converters: AK4456 with 32-bit resolution from Asahi Kasei Microdevices (AKM).

Inputs: 8 x RCA/Cinch, 8 x Highlevel, 1 x optical SPDIF and 1 x coaxial SPDIF
Outputs: 12 x RCA/Cinch with max. 8 Volts output voltage

The HELIX V TWELVE DSP is the first amplifier worldwide that offers 12 high-level inputs and just as many amplifier channels, a digital input and a HEC slot. The integrated DSP can handle this easily, since it comes with the incredible number of 14 separate channels. It incorporates an extraordinary powerful 32-bit CoProcessor of the latest generation for all monitoring and communication tasks, both internally and externally. 

Separate A/D converter: AK5536 and D/A converters: AK4456, AK4458 of the latest generation from Asahi Kasei Microdevices (AKM) with a native resolution of 32-bit ensure optimal sound performance, best possible signal-to-noise ratio and minimal distortion.

The impossible takes a little longer - from the very first idea in 2011 until the sales start at the end of 2018 the all-new BRAX DSP went through the longest and most intensive development process in the history of Audiotec Fischer. 

The "heart" consists of no less than three (3!) of the most advanced Sigma350 series fixed-point 64-bit audio DSP's with the incredible processing power of 3.6 billion MAC operations per second.

This allows to run the whole system on a native 192kHz sampling rate, extending the audio frequency range to 80kHz. The signal conversion is handled by the best sounding A/D: AK5572 and D/A: AK4490 converters from Asahi Kasei Microdevices (AKM) with specifications beyond imagination.

An impressive range of improvements make the new HELIX DSP PRO MK2, (MK2), a great tool to bring a sound system to ultimate sound quality.

The MK2 allows to handle all signals with the doubled sampling rate of 96kHz.  Thus the audio bandwidth is no longer limited to usual values like 22kHz but allows an extended frequency response to more than 40kHz.  Doubling the sampling rate requires significantly higher DSP power as the number of possible arithmetic operations is halved. 

The MK2 achieves high-grade specifications such as 10 to 44,000Hz frequency response, 0.0005% or less distortion, 116dB or more S/N ratio, and 8V output voltage.  It is also equipped with 8 x RCA/Cinch, 8 x Highlevel, 1 x Optical SPDIF, 1 x Coaxial SPDIF in input, and 10 x RCA/Cinch in output.

* The MK2 uses high-class two premium D/A converters: AK4456 and one A/D converter: AK5558 of the latest generation with a native resolution of 32-bit instead of the common 24-bit.
