Small in size, huge in sound!
High tech in compact dimensions – despite its size, the HELIX DSP MINI is crammed with state-of-the-art technology. A 64 Bit Audio DSP of the latest generation in combination with a sampling rate of 96 kHz and a High Resolution audio bandwidth up to more than 40 kHz provides phenomenal sound quality. In addition, the DSP MINI offers unique DSP sound features like the ”Augmented Bass Processing”, the “StageXpander” or the “RealCenter“ function which open new possibilities to tweak your audio system.
But not only in terms of sound quality the DSP MINI heralds a new era in signal processor technology. An extraordinary powerful 32 Bit CoProcessor (ACO) for all monitoring tasks provides a decisive speed increase particularly in data communication with our DSP PC-Tool software, but also when switching between different sound setups. Furthermore, it supplies 10 internal memory locations for sound setups instead of the usual two.
As if that weren't enough – the high-level 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® Audio Streaming or High Resolution Audio Streaming via USB are, of course, part of the basic equipment.
The DSP MINI presents itself in the HELIX-typical, clean look - far too beautiful to hide it "somewhere" in the vehicle due to its small dimensions. Naturally, the HELIX DSP MINI can be configured as easy as usual thanks to the professional and particularly user-friendly DSP PC-Tool Software V4. Who said that size matters?
The “RealCentre” feature is an algorithm, developed by Audiotec Fischer, that emphasizes the music information which is present in both the left and right front channel to create an unique centre signal. In contrast to common procedures, in which only the channels are summed up, the intensity of the centre signal is also dynamically controlled by the stereophonic informational content of the left and right channel.
Sounds complicated but this effect is astonishing: That means if solely the left or right channel delivers an audio signal, the centre channel will not reproduce a signal. In the case of common algorithms, the volume level of the centre channel is only reduced by 6 dB (= half volume level). Audiotec Fischer’s “RealCentre” allows a unique, broadened sound staging for both driver and co-driver at the same time! Therefore, the disadvantages of a conventional centre channel, such as an intrusive, small sound stage, are things of the past.
Augmented Bass Processing
Audiotec Fischer’s proprietary “Augmented Bass Processing”, consisting of the two revolutionary sound features “Dynamic Bass Enhancement” and “SubXpander”, has been especially developed to dramatically improve the bass reproduction of subwoofers.
The “Dynamic Bass Enhancement” ingeniously combines maximum deep bass and highest sound pressure - regardless of the music style or the tone controls in the head unit. Depending on the input signal, the “Dynamic Bass Enhancement” gains the lower frequency range and varies the cut-off frequency of the subsonic filter. The result is a significantly more powerful and deeper bass response at low and medium volume levels without the risk of overloading the subwoofer neither mechanically nor electrically at high volume levels. It is simply fascinating which bass performance is suddenly possible.
If you want an even lower and “darker” bass reproduction, the “SubXpander” can be additionally activated. Therefore, sub-harmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.
Depending on the speaker arrangement in the vehicle, a more or less wide stereo sound stage can be created on the front seats. A centre speaker may limit the spatial reproduction of the music additionally. This is where Audiotec Fischer’s new “StageXpander” comes into play – a sound feature which seems to break the acoustic limitations and thus allows to create a way broader stereo base without negatively affecting the precision of the localisation of voices or instruments!
The effect can be adjusted according to your personal preferences in four steps.
You are looking for more transparency and substance in the treble reproduction? With the “ClarityXpander” Audiotec Fischer is now offering the right tool. Properly adjusted (and therefore selectable in three steps) the feature adds additional harmonics in the upper frequency range – this is especially useful if the original speakers lack some brilliance in the treble response. The extra treble-kick is not only available for the two front channels but also separately adjustable for the centre channel. Even better - the centre channel allows to activate an automatic and dynamic control so that music with “loads” of treble doesn’t fatigue your hearing.
