HELIX DSP MINI MK2
Digital 6 channel signal processor with 96 kHz / 24 Bit signal path
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.
Features
- Extremely powerful “fixed point” Audio DSP with 64 Bit resolution and 1.2 billion MAC operations per second
- High Resolution audio bandwidth up to more than 40 kHz for unrivalled sound quality
- ACO – Advanced 32 Bit CoProcessor for all control and communication tasks
- 10 internal memory locations for sound setups
- Setup switching within milliseconds
- High-speed data transfer and improved usability
- HELIX Extension Card slot (HEC) for system add-ons
- Smart highlevel input with ADEP.3 circuit and Auto Turn-On function
- Start-Stop capability down to 6V supply voltage
- Unique DSP Sound Effects 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
- 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
96 kHz sampling rate
The HELIX DSP MINI allows to handle 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 highlevel input ADEP.3
Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. In particular the latest generation of car radios are 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.
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 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.
