Audio performance par excellence

The HELIX DSP ULTRA S stands for the highest standards in audio performance. A newly designed audio signal path reduces the distortion factor to a minimum: at its heart are the renowned AKM Velvet Sound™ 32 Bit AD and DA signal converters and new, high-quality operational amplifiers from the legendary TI / BurrBrown "OPA series" with SoundPlus™ technology, assuring the highest sound quality. With the completely revised analog input stage, the ULTRA S achieves optimum interference immunity, enabling unsurpassed clarity and detail without external influences, even under the most demanding conditions.

TwinDSP Power

Computing power can only be replaced by even more computing power – which is precisely why the DSP ULTRA S is equipped with two of the most powerful 64 Bit audio signal processors currently available from Analog Devices. With incredible 2.4 billion MAC operations per second, the immense number of internal channels in conjunction with the highest quality sound processing is not even the slightest problem. Therefore, the ULTRA S comes with eight separately processable input channels, eight processable virtual channels and twelve processable output channels as well as numerous new sound features – all this at a sampling rate of 96 kHz, resulting in an audio bandwidth of over 40 kHz.

Virtual Channel Processing – Modern signal routing

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 amplifier. Especially when several input signals are mixed together and then split again into multi-way systems, conventional routing concepts quickly reach their limits. 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, it allows to freely assign our proprietary FX sound features such as "RealCenter" or "Augmented Bass Processing".

Elegant, smart and compact

Despite its vast range of functions, the HELIX DSP ULTRA S 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 S the perfect "tool" for every uncompromising audiophile music lover with highest demands.
