Helix AMI Audio Measurement Interface

The AMI (Audio Measurement Interface) is the ideal precision tool for analyzing electrical and acoustic signals, as well as the perfect companion for anyone requiring maximum accuracy and seamless integration in DSP-based audio systems. Designed as a compact yet versatile interface, it offers all the essential functions needed for precise signal evaluation, system setup and optimization, all perfectly adapted to the capabilities of our DSP PC-Tool software.

The AMI is equipped with a microphone input compatible with all condenser microphones, including 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 accurate analysis of both low and high level signals. The stereo signal output is available via RCA or digital optical connection for direct playback into a DSP. The integrated loopback function offers advanced measurement options, such as precise phase response and more complex signal path evaluations.

Developed to ensure full compatibility with Audiotec Fischer DSP PC-Tool, AMI becomes a powerful measurement tool that unlocks the full potential of our software's optimization features. This includes the Advanced Input Signal Analyzer (AISA) for detecting and correcting EQ curves applied at the factory, time alignment and allpass filters, as well as Real-Time Analyzer (RTA) support for precise frequency response measurements and automatic adjustment via our proprietary TuneEQ algorithm. The AMI also supports Automatic Time Measurement (ATM) for fully automated speaker delay calibration, ensuring perfect synchronization and imaging across all channels.

The AMI operates via USB and requires no external power supply, ensuring maximum mobility and ease of use. The package includes a premium 3 m USB-C cable with USB-A adapter, an RCA to high level signal connector, and a 16 GB USB 3.0 flash drive with pre-installed DSP optimization tracks. Fully compatible with Windows 10 and 11, macOS, Android and iOS and with ASIO driver support for professional audio applications, the AMI is a plug-and-play solution designed for accurate results, wherever your setup takes you.
