Helix DSP PRO MK3 is the new third-generation version of the popular Helix DSP PRO model.

The computing power of a DSP processor can only be improved by increasing the computing power. The Helix DSP PRO MK3 features two of the most powerful 64-bit audio signal processors available from Analog Devices. An incredible 2.4 billion MAC operations per second enable processing of ten individual channels and 96 kHz sample rate.

The AKM Velvet Sound 32Bit A/D and D/A converters used in the Helix DSP PRO MK3 model ensure state-of-the-art audio quality with High-Res quality.

The new ACO platform (ACO = Advanced 32 Bit CoProcessor) allows you to do everything fast, but it also does a lot more.

One of the most significant new features of this new processor is the ISA (Input Signal Analyzer) and the InputEQ, i.e. input signal measurement and equalization. ISA measures the frequency response of the input signal and InputEQ is a channel-specific 5-channel parametric corrector to correct for possible distortions in the frequency response of the input signal. This provides a solid starting point for the best possible audio reproduction.

The Helix DSP PRO MK3 installs seamlessly behind any OEM audio source ADEP.3 The 4-32 volt input sensitivity of the speaker level input allows installation on the rear of OEM amplifiers in cars where removal from the rear of the player is impossible.

The signal can be input as speaker level, line level, optical or via the optional Helix HEC module via Bluetooth or HD level via USB cable.

The High Level Input features the most advanced Autostart function on the market with a switch-off delay adjustment of 10-300 seconds. The device will only switch on when it detects the correct speaker signal, and will not react to start-up bursts or other disturbances. Like Audiotec Fischer's other plug & play devices, it is ideal for CAN bus radios, where the radio can be on for up to 40 minutes after locking the door.

DSP PC-Tool 5
Helix DSP PRO MK3 is compatible with Audiotec Fischer's new DSP PC-Tool 5.
The software is future-proof with almost unlimited upgrade possibilities. The DSP is connected to the USB 2.0 port of the computer for adjustment.
