Helix DSP Mini MK2

Helix DSP Mini MK2

The Helix DSP MINI MK2 is a new improved version of the popular Helix DSP MINI model. The 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 incredibly fast and efficient.

ISA & Input EQ
The Helix DSP MINI MK2 model features 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 distortions in the frequency response of the incoming signal. This provides a proper starting point for the best possible sound reproduction.

Signal Input
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.

Powerful processor
Processor speed is a very important feature when adjusting an audio system. The slower the processor, the more the dynamics will flatten out when adjusting equalization or crossovers. 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 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.

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

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

DSP PC Tool Version 4

The software is future-proof with almost unlimited upgrade options. The DSP is connected to the computer's USB 2.0 port during adjustments. When connecting a computer to the DSP processor for the first time, the computer must have an internet connection so that the computer can download the necessary USB drivers from the internet and install them.
