HELIX DSP.3S High-Res 6 in 8 out digital signal processor DSP 1 x helix dsp.3s HELIX DSP.3SDSP standard redefinedThe HELIX DSP.3S is our new definition of the standard for digital signal processors.Continuously developed, this 8-channel DSP presents numerous detailed improvements. In addition to 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. The most advanced technology for the ultimate high-res sound experienceThe 64-bit audio DSP of the latest Sigma350 generation and a consistent, native signal processing with 96 kHz sampling rate as well as the AD and DA signal converters from BurrBrown ensure impressive sound quality. This means that the DSP.3S is perfectly equipped to process high-res audio signals with an audio bandwidth of more than 40 kHz. ACO - Advanced 32-bit CoProcessor PlatformOf course, the DSP.3S is equipped with the proprietary 32-bit ACO platform. This not only takes over all control tasks extremely quickly, but also switches between the up to ten possible sound setups at lightning speed. But ACO offers much more - fantastic sound effects such as augmented bass processing, StageXpander or RealCenter are implemented as well as a channel-separated input EQ including input signal analyzer (ISA) for easy analysis and compensation of the input signals from OE radios, which already have a sound ex works -Setup include. Practical equipment for optimal connectivityThe well thought-out equipment of the DSP.3S offers everything for a simple connection to factory radios or multi-channel factory sound systems. In addition to the intelligent high-level input with ADEP.3 circuit, an optical and now also a coaxial digital input, an auto remote switch and the HEC slot for system expansions such as Bluetooth® HD audio streaming etc. are also part of the basic equipment.But that's not all - in the course of the revision, the new Smart Control Port (SCP) also found its way into the DSP.3S. This allows the multifunctional connection of accessory products and now even takes over their complete power supply. The solid construction and the snap-in function guarantee a stable connection, prevent cable and connector damage and thus facilitate space-saving installation concepts. focus on the essentialsHELIX-typical, clear and very compact - in terms of design, the DSP.3S offers ideal conditions for quick and easy integration. DSP PC tool – fine tuning for the highest demandsWithout question, the HELIX DSP.3S can be easily configured using our professional and at the same time very user-friendly DSP PC tool software. The numerous setting options leave nothing to be desired and thus guarantee an extremely precise sound adjustment even with complex system configurations. featuresExtremely powerful "Fixed Point" audio DSP with 64-bit resolution and 1.2 billion MAC operations per secondHigh resolution audio bandwidth of over 40kHz for unmatched sound qualityBurrBrown AD and DA signal convertersAdvanced CoProcessor (ACO) for extended functionalityInput Signal Analyzer (ISA) and InputEQDSP sound effects (SFX) such as "Augmented Bass Processing" for dynamic optimization of the bass reproduction of the subwoofer, "StageXpander" for broadening the stereo perspective, the "RealCenter" function, which enables the driver and front passenger to have an equally perfectly focused stage image and much more10 internal memory locations for sound setupsIntelligent high-level input with ADEP.3 circuit and automatic switch-onOptical (max. 96 kHz) and coaxial (max. 192 kHz) digital input in SPDIF formatCompact, future-proof Smart Control Port (SCP)HELIX Extension Card slot (HEC Slot) for system extensions such as Bluetooth ® Audio Streaming, High Resolution Audio Streaming via USB etc.Freely definable signal routing with separate matrices for Line, SPDIF and HEC/AUXOptimal signal routing and power supply for excellent sound quality"Ground lift" switch to avoid ground loopsCompact dimensions for problem-free integrationExtremely simple configuration via the intuitive DSP PC-Tool V4 softwareSpecial Features:96kHz sample rateThe HELIX DSP.3S offers signal processing with a double sampling rate of 96 kHz. As a result, the audio bandwidth is not limited to 22 kHz as usual, but allows an extended frequency response of over 40 kHz. However, the higher sampling rate places significantly higher demands on the DSP itself, because the number of possible arithmetic operations is reduced by half when the sampling rate is doubled. Only the use of the very latest chip generation makes it possible to increase the sampling rate to 96 kHz despite the increased range of functions. ACO—Advanced 32-bit CoProcessorThe HELIX DSP.3S uses a particularly powerful 32-bit CoProcessor of the latest generation for all internal and external control and communication tasks. In contrast to the previously used 8-bit processor, this results in significant speed advantages, not only when switching between different sound setups, but above all in data communication with our DSP PC tool software. Another major advantage is the CoProcessor's integrated, native bootloader. This enables software upgrades of all components of the DSP, for example to be able to adapt the microcontroller-controlled ADEP.3 circuit to changes in the diagnostic systems of factory radios in the future or to expand the device with additional interfaces. Intelligent high-level input ADEP.3Modern, factory-installed car radios are becoming more and more intelligent when it comes to diagnosing the connected loudspeakers. The latest generation in particular is equipped with additional monitoring functions, so that error messages or even malfunctions can occur when an additional signal processor is connected. The new ADEP.3 circuit (Advanced Diagnostics Error Protection Generation 3) prevents these problems without unnecessarily loading the speaker outputs of the radio at high levels. start-stop capabilityThe power pack in the HELIX DSP.3S ensures the internal power supply even in the event of short-term dips down to 6 volts.This ensures that the HELIX DSP.3S remains fully functional even when the engine is started. Power save modeThe Power Save mode is activated in the basic settings of the DSP PC-Tool software. It allows to drastically reduce the power consumption of the amplifiers connected to the signal processor when there is no input signal for more than 60 seconds. It should be noted that many vehicles today are equipped with "CAN" or similar internal bus systems that leave the radio "invisible" to the user for up to 45 minutes, even if you have left the vehicle in the meantime and locked it. As soon as the "Power Save Mode" is active, the remote output and thus the connected amplifiers are switched off. The HELIX DSP.3S reactivates the remote output within one second as soon as a music signal is present at one of its inputs. It is also possible Automatic digital signal detectionThe HELIX DSP.3S allows signal-controlled switching between the analogue and the digital inputs. As soon as an audio signal is detected at the optical input or coax input , the signal processor switches to this input. This function can be activated in the DSP PC-Tool software or, alternatively, manual control can be selected using an optionally available remote control .

DSP featuresRealCenterThe "RealCenter" function is an Audiotec Fischer proprietary algorithm that emphasizes the monaural information of the left and right front channels to create a unique center signal. In contrast to conventional methods, in which only the channels are summed up, there is also a dynamic control of the center signal through the stereophonic information content of the left and right channel. This means that the center channel does not reproduce a signal if only the left channel or only the right channel provides an audio signal. With the usual algorithms, the center channel would only be 6 dB quieter in this case. Audiotec Fischer's "RealCenter" thus enables a unique, wide-ranging stage image - and that's ideal for driver and passenger alike! Augmented bass processingAudiotec Fischer's proprietary "Augmented Bass Processing", consisting of the two revolutionary sound features: "Dynamic Bass Enhancement" and "SubXpander". These are specifically designed to dramatically improve bass response from subwoofers."Dynamic Bass Enhancement" combines in an ingenious way maximum deep bass foundation and high maximum sound pressure - regardless of the type of music you are listening to or the sound settings on the radio. Depending on the input signal, "Dynamic Bass Enhancement" boosts the lower frequency range on the one hand and varies the cut-off frequency of the subsonic filter on the other. The result is a significantly more powerful, deeper bass reproduction at low and medium volumes without running the risk of mechanically or electrically overloading the subwoofer at high volumes. It's simply fascinating what kind of bass performance is suddenly possible.If you want the bass range to be a little deeper and "blacker", you can also activate the "SubXpander". Here, additional subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz. StageXpanderDepending on the arrangement of the loudspeakers in the vehicle, a more or less wide stereo stage can be created on the front seats. If a center loudspeaker is also installed, this sometimes additionally limits the spatial reproduction of the music. This is where Audiotec Fischer's new "StageXpander" comes into its own - a sound feature that seems to eliminate acoustic boundaries and thus enables a significantly broader stereo base without negatively affecting the precision in the localization of voices or instruments. The effect can be adjusted to personal taste in four stages. ClarityXpanderWould you like more transparency and substance in the high-frequency reproduction? Audiotec Fischer now offers exactly the right tool for this with the "ClarityXpander".Correctly dosed (and therefore selectable in three stages), it gives the overtones additional radiance - particularly useful if the original loudspeakers lack the necessary shine in the high-frequency range. The extra treble kick is not only available for the two front channels, but also separately adjustable for the center channel. And because a little too much in connection with musical material rich in overtones tires the ear, especially with the latter, an automatic, dynamic control of the additional overtone component can even be activated here.
