HELIX DSP PRO MK3
Helix DSP PRO MK3 is the new third generation version of the popular Helix DSP PRO model.
The only way to improve the processing power of a DSP processor is to add more processing power. The Helix DSP PRO MK3 features two of the most powerful 64-bit audio signal processors in the Analog Devices portfolio. An incredible 2.4 billion MAC operations per second enable processing of ten individual channels and a 96 kHz sampling rate.
The AKM Velvet Sound 32Bit A/D and D/A converters used in the Helix DSP PRO MK3 ensure top-notch sound quality in High-Res quality.
The new ACO platform (ACO = Advanced 32 Bit CoProcessor) enables fast performance in everything, but it also does much more.
One of the most significant innovations of this new processor is ISA (Input Signal Analyzer) and InputEQ, i.e. input signal measurement and equalizer. ISA measures the frequency response of the incoming signal and InputEQ is a channel-specific 5-channel parametric equalizer that can correct any possible distortions in the frequency response of the incoming signal. This provides a proper starting point for the best possible sound reproduction.
The Helix DSP PRO MK3 seamlessly integrates with any OEM audio source thanks to the ADEP.3 circuitry and incredibly wide input sensitivity. The 4-32 Volt input sensitivity on the speaker level input allows installation behind OEM amplifiers in cars where removing it from the player is impossible.
The signal can be brought in at speaker level, line level, optical or via the optional Helix HEC module via Bluetooth or at HD level via a USB cable.
High Level Input has the most advanced Autostart function on the market with a switch-off delay adjustment of 10-300 seconds. The device only turns on when it detects the correct speaker signal, and does not react to start-up pops or other disturbances. Like other plug&play devices from Audiotec Fischer, it is an ideal product for radios implemented with a CAN bus, where the radio may be on for up to 40 minutes after the doors are locked.
DSP PC Tool 5
Helix DSP PRO MK3 is compatible with Audiotec Fischer's new DSP PC-Tool 5 version.
The software is future-proof with almost unlimited upgrade options. The DSP is connected to the computer's USB 2.0 port for adjustments.
