Helix DSP MINI Digital Signal Processor + Wifi Module + URC Bundle

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, but the DSP MINI also 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 wasn'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?

Special features:

96 kHz sampling rate

The HELIX DSP MINI allows handling all signals with the doubled sampling rate of 96 kHz. Thus the audio bandwidth is no longer limited to usual values like 22 kHz but allows an extended frequency response to more than 40 kHz. Doubling the sampling rate requires significantly higher DSP power as the number of possible arithmetic operations is halved.

Only the implementation of the latest DSP chip generation allows raising the sampling rate to 96 kHz and adding new features at the same time.


Smart high-level input ADEP.3

Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. In particular, the latest generation of car radios is equipped with additional monitoring functions so that failure messages and loss of specific features (e.g. fader function) quite often appear if a signal processor will be hooked up - but not with the DSP MINI.

The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.


ACO - Advanced 32 Bit CoProcessor

The HELIX DSP MINI incorporates an extraordinary powerful 32 Bit CoProcessor of the latest generation for all monitoring and communication tasks, both internally and externally. In opposite to the 8 Bit predecessor generation, this MCU achieves way higher speeds with respect to setup switching and data communication with our DSP PC-Tool software. A further significant advantage is the integrated, native boot loader of the CoProcessor. It allows software upgrades of all components of the DSP in order to adjust the microcontroller-controlled ADEP.3 circuit for example at future modifications/changes in the diagnostic system of factory radios or if the device will be extended with additional interfaces. In addition, thanks to the new flash memory, the ACO offers 10 memory locations for sound setups instead of the common two.


Start-Stop capability

The switched power supply of the HELIX DSP MINI assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.


Power Save Mode

The Power Save Mode is incorporated in the basic setup. It allows to significantly reduce the power consumption of the amplifiers that are connected to the HELIX DSP MINI once there’s no input signal present for more than 60 seconds. Please note that in many up-to-date cars with “CAN” or any other internal bus structures it may happen that the radio remains “invisibly” turned on for up to 45 min. even after locking and leaving the car! Once the “Power Save Mode“ is active the remote output and therefore the connected amplifiers will be turned off. The HELIX DSP MINI will reactivate the remote output within a second if a music signal is applied. It is possible to either modify the turn-off time of 60 sec. or completely deactivate the “Power Save Mode” via the DSP PC-Tool software.

Automatic Digital Signal Detection

Switching from analogue input to the digital input is done automatically as soon as a signal is detected on the Optical Input. This feature can be deactivated in the DSP PC-Tool software. Alternatively, you can use an optional remote control for manual switching between analogue and digital inputs.

RealCenter

The “RealCenter” 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 a 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 “RealCenter” 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 specially 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, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.


StageXpander

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 localization of voices or instruments!

The effect can be adjusted according to your personal preferences in four steps.


ClarityXpander

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 activating an automatic and dynamic control so that music with “loads” of treble doesn’t fatigue your hearing.


Wireless DSP configuration

Bye-bye USB cable! The WIFI CONTROL allows the comfortable configuration of Audiotec Fischer DSP products via wireless communication between PC and DSP device.


Remote control through app management

All DSP products with the ACO platform offer additional features such as volume control of all sources, subwoofer volume control, source selection, tone control and switching between sound setups via Android, iOS or the web app.

The web app is compatible with different operating systems like Apple iOS, Android, Microsoft Windows, Linux, etc.
