Audiotec Fischer AMI - Audio Measurement Interface

Audiotec Fischer AMI

AMI – Precision Put into Practice

The AMI (Audio Measurement Interface) is the precision tool of choice for analyzing electrical and acoustic signals – and the ideal companion for anyone who values the highest accuracy and seamless integration into DSP-based audio systems. As a compact yet versatile interface, it offers all the essential functions for precise signal analysis, system tuning, and optimization – perfectly matched to the capabilities of our DSP PC-Tool software.

Flexible Signal Access for Every Scenario

The AMI features a microphone input compatible with all condenser microphones and features adjustable gain and switchable phantom power – ideal for professional acoustic measurements. A dedicated line input with switchable sensitivity (max. 1 V or 40 V) ensures precise analysis of low- and high-level signals. The stereo signal output is available via RCA or an optical digital connection for direct playback into a DSP. The integrated loopback function opens up advanced measurement capabilities, such as precise phase response and more complex signal path analysis.

Matching: Seamless integration with DSP PC tool

Designed for full compatibility with the Audiotec Fischer DSP PC tool, the AMI is a powerful measuring device that unlocks the full potential of our software's tuning features. These include the Advanced Input Signal Analyzer (AISA) for detecting and correcting factory-set EQ curves, time alignment, and all-pass filters, as well as support for the Real-Time Analyzer (RTA) for precise frequency response measurements and automated tuning via our proprietary TuneEQ algorithm. The AMI also supports Automatic Time Measurement (ATM) for fully automatic speaker delay calibration – for perfect timing and picture quality across all channels.

Ready to use – straight out of the box

The AMI is USB-powered and requires no external power supply. This ensures maximum mobility and ease of use. Included in the package are a high-quality 3 m USB-C cable with a USB-A adapter, an RCA-to-high-level signal connector, and a 16 GB USB 3.0 flash drive with pre-installed DSP tuning tracks. The AMI is fully compatible with Windows 10 & 11, macOS, Android, and iOS and supports ASIO drivers for professional audio applications. It's a plug-and-play solution for precise results – no matter where you use your setup.
