Helix DSP Mini MK2

Helix DSP Mini MK2

Helix DSP MINI MK2 is a new improved version of the popular Helix DSP MINI model. Helix DSP MINI MK2 is guaranteed to be one of the best DSP processors on the market in terms of price/quality ratio.

ACO
Thanks to the ACO Platform (ACO = Advanced 32 Bit CoProcessor), the device is extremely fast and efficient.

ISA & InputEQ
The Helix DSP MINI MK2 model has 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 parameter corrector that corrects possible distortions of the frequency response of the incoming signal. This provides a decent starting point for the best possible sound reproduction.

Signal Input
The signal can be brought in as speaker level, line level, optical or with the help of the Helix HEC module sold as an accessory via Bluetooth or HD level with a USB cable.

Powerful processor
The speed of the processor is a very important feature when adjusting the audio system. The slower the processor is, the more the dynamics slows down when adjusting the equalization or dividing slopes. This processor has the latest technology 64-bit 295Mhz processor with a speed of 1.2 billion calculations per second.

Autostart
High Level Input has the most advanced Autostart function on the market, with an adjustable switch-off delay of 10-300 seconds. The device starts up only after detecting the correct speaker signal, does not react to start-up bangs or other disturbances. Like Audiotec Fischer's other plug&play devices, 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.

6 channels
With this device you can make all the divisions of the 3-way system and the delays of each element. The 3-way system includes an active 2-way front end and subwoofer. This device is also suitable for a system with a passive separate set in front, rear speakers and subwoofer. There are 6 channels in use, the characteristics of which can be defined for each channel yourself.

DSP processor adjustments are made on a Windows computer with the free DSP PC-Tool Version 4 software found on Audiotec Fischer's website. Below are the links to the Audiotec Fischer website and the DSP PC Tool software download page.

DSP PC-Tool Version 4

The software has taken into account the future with almost unlimited update possibilities. During adjustments, the DSP is connected to the computer's USB 2.0 connection. When connecting the computer to the DSP processor for the first time, the computer must have an Internet connection so that the computer can search for the necessary USB drivers from the Internet and install them.
