Computing 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.
Rapid processing power not only in the signal path – the particularly fast 32 Bit ACO platform takes overall 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.
The HELIX DSP ULRA justifies its name not only in terms of functionality but also with respect to sound quality. An extremely complex and newly designed analog input stage ensures phenomenal sound characteristics with full high-res audio bandwidth up to more than 40 kHz. But that’s not all – tremendous effort was put into filtering out any unwanted interference in the power supply of the individual stages. In addition, only particularly low-noise operational amplifiers from TI / BurrBrown’s legendary “OPA series” are now used.
The adaptation to modern OE sound systems via an increasing number of inputs has a significant impact on the complexity of the signal routing inside the processor. Especially when several input signals are mixed together and then split again into multi-way systems, conventional routing concepts quickly reach their limits, both in terms of implementation and usability. Audiotec Fischer’s new, multi-stage “Virtual Channel Processing”, in conjunction with the recognized user-friendly DSP PC-Tool software, makes it easy to realize even highly complex system configurations. Besides that, it allows us to freely assign our proprietary FX sound features such as “RealCenter” or “StageEQ”.
The simple adaptation to existing factory radios or multi-channel OE sound systems is more important than ever before – and that’s why the DSP ULTRA is not only equipped with the latest generation ADEP.3 circuit but also offers a particularly large adjustment range for the input sensitivity. The enormous range of 1 – 8 Volts (RCA) or 4 – 32 Volts (high level) allows the combination with almost any imaginable analog signal source, even with high-power OE amplifiers.
Despite its vast range of functions, the new HELIX DSP ULTRA inspires with its straightforward and timeless design that is still compact – ideal for a simple installation. The sum of its characteristics makes the HELIX DSP ULTRA the perfect “tool” for every uncompromising audiophile music lover with the highest demands.
In its diversity, music directly touches the heart of the listener.
You can almost hear and feel the passion when the sound is reproduced as the performer intended.
For this reason, Audiotec Fischer develops the HELIX audio products with the same dedication and precision as their audiophile reference devices from BRAX. As with the quality of musical instruments, high-quality audio components have a significant influence on the naturalness of the timbre. We believe in having found the perfect DNA of sound in HELIX, resulting in a realistic, precise, and powerful sound inside your car.
Sound quality at the highest level by music lovers for music lovers.
Like no other brand, HELIX stands for the development and manufacturing of the most sophisticated car hi-fi components with its decades of experience. The brand’s success is no coincidence, but rather the result of meticulous research and numerous, proprietary core technologies.
Each of the HELIX products is designed and developed in-house by Audiotec Fischer down to the last detail. The result is a smart product range with an ideal solution for every application. Always with the aim of satisfying our basic need for rhythm and music.
The power supply has a significant influence on the sound quality. Only with a stable power source in all modules is it possible to guarantee full dynamics and purity of the reproduction.
Audiotec Fischer’s proprietary power supply technologies combine maximum efficiency with minimum space requirements. In addition, unconditional stability regardless of the onboard voltage is guaranteed – ideal for use in vehicles with start-stop feature.
Anyone who speaks of high-end HiFi in the digital domain also automatically considers hi-res audio formats such as Tidal, Deezer, or Qobus.
With HELIX we offer a complete signal chain with HiRes-capable DSPs and amplifiers, which enables lossless audio playback in the car.
More high-end sound inside a vehicle is hardly possible.
The 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.
