Helix AMI Professional Tuning Kit
The AMI tuning kit is a professionally equipped package that combines the precision AMI interface with selected premium accessories. It provides everything needed for thorough analysis of electrical and acoustic signals and for precise tuning of modern DSP systems. The entire set is designed as an all-in-one solution ready for immediate use—whether you work in the workshop or directly in the vehicle. At the core of the kit is the AMI interface, fully optimized for Audiotec Fischer’s DSP PC-Tool software and complemented by a high-end microphone and necessary cabling accessories.
Accurate measurements anywhere on the road
The AMI interface serves as the central unit for all measurements and offers extensive connectivity for signal and acoustic analysis. The kit includes the Beyerdynamic MM-1, a highly accurate condenser measurement microphone made in Germany, calibrated and optimized for the automotive environment. A line input with selectable sensitivity (1 V or 40 V RMS) allows precise evaluation of both low- and high-level signals. With stereo outputs via RCA or optical digital connection, the signal can be routed directly to the DSP, while the loopback function enables advanced measurements such as phase response or analysis of complex signal paths.
Perfect integration with DSP PC-Tool software
AMI is engineered from the ground up to work seamlessly with the DSP PC-Tool software. This gives you AISA (Advanced Input Signal Analyzer) for detecting and correcting factory equalization curves, time alignment, or all-pass filters. RTA (Real-Time Analyzer) is also supported for detailed frequency response measurements and automatic tuning using the TuneEQ algorithm. The kit also includes ATM (Automatic Time Measurement), which automatically sets speaker time delays to ensure perfect phase alignment of all channels.
Everything you need in one package
The kit includes not only the AMI interface and the Beyerdynamic MM-1 microphone but also a complete set of high-quality cables and accessories: a USB-C cable with a USB-A adapter, RCA cable with high-level adapters, a Toslink cable, an XLR cable for the microphone, and a 16GB USB 3.0 flash drive with preinstalled DSP tuning tracks. The entire kit is stored in a durable, compact case, powered via USB and ready to use immediately—anytime, anywhere.
