The new Generation of sound – HELIX DSP.2
Design-wise, it is as precious and compact as before, the Helix DSP.2 unveils its new "technical heart" with integrated state-of-the-art technology.
The cutting-edge 64 Bit “fixed point” Audio DSP with a breath-taking processing power of 295 MHz and 1.2 billion MAC operations per second provides unparalleled sound optimization options, not solely in this price range.
The connectivity options are by no means a short list – six RCA/Cinch and six highlevel inputs with ADEP circuit (Advanced Diagnostics Error Protection), an optical SPDIF input and eight RCA/Cinch outputs with a maximum of 6 Volts output, will enable the most flexible car audio configurations you have ever thought of.
However, there's even more than that – the HELIX Extension Card slot (HEC) allows the addition of further input sources, like a Bluetooth® Audio Streaming module or a High Resolution Audio USB soundcard.
That is not all, what is a DSP without the tools to configure it? The DSP PC-Tool V4 has been given a new lease on life as it has been completely revamped. To note but a few of the new features:
- All Pass filter option
- Increased adjustment range of the time alignment
- Switchable sound options of the DA converters
These are but a few examples and despite its extended feature set, the configuration of the DSP could not be easier thanks to clean design and ease of navigation, which leaves nothing to be desired due to its numerous sound optimization options.
No doubt - the HELIX DSP.2 will again make dreams of the most ambitious sound enthusiasts come true - that´s a safe bet!
- Extremely powerful “fixed point” Audio DSP with 64 Bit resolution and 1.2 billion MAC operations per second
- HELIX Extension Card slot (HEC) for additional input / output modules like Bluetooth® Audio Streaming, High Resolution Audio Streaming via USB etc.
- Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection)
- Start-Stop capability down to 6V supply voltage
- Freely definable signal routing with separate matrices for line, SPDIF and HEC/AUX
- Time alignment with up to 20 ms delay time per channel, additionally reverse time alignment for in-phase summation of the inputs
- Optimized signal path and power supply for further improved sound quality
- “Ground lift” switch to avoid ground loops
- Control input for connecting remote controls and accessories
- Inputs: 6 x RCA/Cinch, 6 x Highlevel and 1 x optical SPDIF
- Outputs: 8 x RCA/Cinch with max. 6 Volts output voltage
- Easy configuration thanks to the professional and user-friendly DSP PC-Tool Version 4 software
Smart highlevel input
The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common signal processor will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appears - but not with the DSP.2.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
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.2 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.2 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.
The switched power supply of the HELIX DSP.2 assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.
Automatic Digital Signal Detection
Switching from analog 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 analog and digital inputs.
