Entering a new dimension

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.

TwinDSP Power

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.

ACO – Advanced 32 Bit CoProcessor platform

Rapid 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.

Even further improved audio performance

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.

Virtual Channel Processing  - a new era of signal routing begins

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 to freely assign our proprietary FX sound features such as "RealCenter" or "StageEQ".

Absolute connectivity

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 (highlevel) allows the combination with almost any imaginable analog signal source, even with high-power OE amplifiers.

Elegant, smart and compact

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 highest demands.
