Description
Overview
The complete solution for in-car signal and acoustic measurement
The AMI Tuning Kit is a fully equipped measurement suite that combines the professional-grade AMI interface with a selection of premium accessories, offering everything required for precise signal and acoustic analysis in modern DSP-driven sound systems. Developed as a comprehensive, ready-to-use package, it’s the perfect solution for those who demand maximum accuracy, seamless integration, and flexible mobile use. At its heart: the AMI – engineered to work in perfect harmony with Audiotec Fischer’s DSP PC-Tool software, and enhanced by intelligent accessories for real-world measurement scenarios.
High-precision acoustic and signal measurement – anywhere you need it
The AMI serves as the central measurement hub, providing all relevant connections for a wide range of electrical and acoustic analysis tasks. Included in the kit is the renowned Beyerdynamic MM-1 – a precision-calibrated condenser measurement microphone „Made in Germany“, optimized for in-car measurements with a linear frequency response at 90°. The dedicated line input with switchable sensitivity (max. 1 V or 40 V) ensures accurate analysis of both low- and highlevel signals. Stereo signal output is available via RCA or optical digital connection for direct playback into a DSP. The integrated loopback function opens up advanced measurement options, such as precise phase response and more complex signal path evaluations.
Made to match: Seamless integration with DSP PC-Tool
Developed for full compatibility with the Audiotec Fischer DSP PC-Tool, the AMI becomes a powerful measurement device that unlocks the full potential of our software‘s tuning features. This includes the Advanced Input Signal Analyzer (AISA) for the detection and correction of factory-applied EQ curves, time alignment and allpass filters, as well as Real-Time Analyzer (RTA) support for precise frequency response measurements and automated tuning via our proprietary TuneEQ algorithm. The AMI also supports Automatic Time Measurement (ATM) for fully automated speaker delay calibration – delivering perfect timing and imaging across all channels.
The all-in-one measuring suite – with premium accessories
Alongside the AMI and the Beyerdynamic MM-1 microphone, the kit includes a full suite of high-quality accessories to ensure seamless operation in the field: a 3 m USB-C cable with USB-A adapter, a RCA cable with RCA-to-Highlevel adaptors, Toslink cable, and an XLR microphone cable. The 16 GB USB 3.0 flash drive preloaded with DSP tuning tracks rounds out the set. Powered via USB and packed in a durable, compact transport case, the AMI Tuning Kit offers maximum portability and convenience – whether in the workshop or directly inside the vehicle.
