Helix DSP MINI MK2
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 for its price/performance ratio.

ACO
The ACO platform (ACO = Advanced 32 Bit CoProcessor) makes the device blazing fast and efficient.

ISA & InputEQ
The Helix DSP MINI MK2 features ISA (Input Signal Analyzer) and InputEQ (Input Signal Measurement and Equalization). The ISA measures the frequency response of the input signal and the InputEQ is a 5-channel per-channel parameter corrector to correct for possible distortions in the frequency response of the input signal. This provides a proper starting point for the best possible audio performance.

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

Powerful Processor
Processor speed is a very important feature when adjusting an audio system. The slower the processor, the more the dynamics are flattened when adjusting eqvals or divider slopes. This processor features a state-of-the-art 64-bit 295Mhz processor with 1.2 billion calculations per second.

Autostart
The High Level Input has the most advanced Autostart function on the market with a 10-300 second shutdown delay. 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 an ideal product for CAN bus radios, where the radio can be on for up to 40 minutes after locking the doors.

6 channels
This device allows you to do all sections of a 3-way system and the delay of each element. The 3-way system includes an active 2-way front end and subbar. This unit also works well with a system with a passive separate front, rear speakers and subbar. There are 6 channels available with customizable characteristics for each channel.

DSP processor adjustments are made on a Windows PC 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 designed with the future in mind with almost unlimited upgrade possibilities. The DSP is connected to the USB 2.0 port of your computer for adjustment. When connecting the computer to the DSP processor for the first time, the computer must be connected to the Internet to retrieve and install the necessary USB drivers.
