AUDIOTEC FISCHER HELIX DIGITAL SIGNAL PROCESSORS (DSP)

HELIX DSP MINI MK2

The next generation of the miniature DSP

The smallest HELIX signal processor gets a worthy successor with the DSP MINI MK2. Like its ancestor, this compact DSP is a real technology package. A powerful 64 Bit audio DSP and BurrBrown converters combined with 96 kHz sampling rate and high resolution audio bandwidth up to over 40 kHz provide exceptional sound quality. The MK2 is also at the top level in terms of measured values – a higher maximum output voltage of 6 Volts, significantly increased signal-to-noise ratio and reduced THD ensure the perfect sound. Of course, the DSP MINI MK2 is based on the ACO platform with 32 Bit CoProcessor, which not only handles all control tasks with incredible speed, but also enables proprietary sound effects such as Augmented Bass Processing or RealCenter and, last but not least, a channel-separated Input EQ including Input Signal Analyzer (ISA).

Seamless integration and maximum control even in the smallest spaces

As the installation space for sound systems in modern vehicles is becoming increasingly limited, the connection of individual components is getting more complicated and puts the durability of plugs and cables to the test. The Smart Control Port (SCP) of the DSP MINI MK2 allows the multifunctional connection of accessory products and now even takes over their complete power supply. The solid design with snap-in function guarantees a stable connection while helping to prevent plug and cable damage and thus facilitates compact, space-saving installation concepts.

All on board

The equipment package makes it clear that the name of the DSP MINI MK2 only refers to the dimensions as there are absolutely no compromises in terms of functionality. Our intelligent highlevel input with ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation), the Auto Remote switch, an optical input as well as the HELIX Extension Card slot (HEC slot) for system add-ons like Bluetooth® HD or High Resolution audio streaming via USB are, of course, part of the basic features.

Features

• Extremely powerful 64 Bit “fixed point” Audio DSP with 1.2 billion MAC operations per second
• High Resolution audio bandwidth up to more than 40 kHz for unrivalled sound quality
• A/D and D/A signal converters from BurrBrown
• Advanced CoProcessor (ACO) for extended feature set
• Input Signal Analyzer (ISA) and InputEQ
• DSP Sound Effects (SFX) such as the “Augmented Bass Processing” which dynamically optimizes the bass response of the subwoofer, the “StageXpander” that significantly widens the stereo perspective, the “RealCenter” function, which allows a perfectly focussed sound staging for both driver and co-driver and much more
• 10 internal memory locations for sound setups
• Smart highlevel input with ADEP.3 circuit and Auto Turn-On function
• Optical digital input in SPDIF format
• Compact, future-proof Smart Control Port (SCP)
• HEC slot for system expansions for additional input / output modules like Bluetooth® Audio Streaming, High Resolution Audio Streaming via USB etc.
• Freely definable signal routing with separate matrices for line, SPDIF and HEC/AUX
• Optimal signal path and power supply for further improved sound quality
• “Ground lift” switch to avoid ground loops
• Very compact dimensions for easy integration into the vehicle
• Easiest configuration via the intuitive DSP PC-Tool V4 software

HELIX DSP.3S

Refining our standards

The HELIX DSP.3S is our new definition of the standard for digital signal processors. Continuously refined, this 8-channel DSP presents numerous improvements in detail. Besides the obligatory optical digital input, an additional coaxial digital input now provides the best conditions for connecting high-resolution signal sources with a sampling frequency of up to 192 kHz.

Most advanced technology for ultimate High-Res sound experience

The 64 Bit audio DSP of the latest Sigma350 generation and a throughout, native high resolution signal processing with 96 kHz sampling rate as well as A/D and D/A signal converters from BurrBrown provide outstanding sound quality. This makes the DSP.3S perfectly prepared for processing High-Res audio signals with a bandwidth of more than 40 kHz.

ACO – Advanced 32 Bit CoProcessor platform

Of course, the DSP.3 is also equipped with our proprietary 32 Bit ACO platform. This not only takes over all control tasks ultra-fast, but also 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 by default.

Practice-oriented features for maximum connectivity

The sophisticated features of the DSP.3S offer everything for easy connection to factory radios or multi-channel factory sound systems. In addition to the smart highlevel input with ADEP.3 circuit, an optical and now also a coaxial digital input, an Auto Remote switch as well as a HEC slot for system expansions such as Bluetooth® HD audio streaming etc. are also part of the basic equipment.

But that’s not all – The new Smart Control Port (SCP) was implemented during the DSP.3S review process. This allows the multifunctional connection of accessory products and now even takes over their complete power supply. The solid design with snap-in function guarantees a stable connection while helping to prevent plug and cable damage and thus facilitates compact, space-saving installation concepts.

Focus on the essentials

HELIX-typical, clean and very compact design – therefore, the DSP.3S offers ideal conditions for quick and easy integration.

DSP PC-Tool – fine tuning for highest demands

There is no doubt – the HELIX DSP.3S is easily configurable via our professional and yet very user-friendly DSP PC-Tool software. The numerous adjustment options leave nothing to be desired and thus guarantees extremely precise sound adaption even with complex system configurations.
