AMI Audio Measurement Interface

Genuine Audiotec Fischer AMI (Audio Measurement Interface) — the standalone measurement interface used to properly tune DSP-driven car audio systems, on its own, without the calibrated microphone.

• AMI Interface: Microphone input (adjustable gain, 24V phantom power) and line input (switchable 1V/40V sensitivity), 95dB dynamic range (mic) / 101dB (line), stereo RCA and optical digital outputs, 96kHz/32-bit sampling, loopback for phase testing, USB-powered
• Included: 3m USB-C to USB-A cable with adapter, RCA-to-highlevel connector, 16GB USB 3.0 flash drive preloaded with DSP tuning tracks, quick start guide
• Not included: measurement microphone — this listing is the interface only
• Compatibility: Windows 10/11, macOS, Android, iOS — works with Audiotec Fischer's DSP PC-Tool software

Used to measure factory-applied EQ curves, perform time alignment calibration, run real-time frequency analysis, and execute automated speaker delay calibration via the DSP PC-Tool's AISA, RTA, ATM and TuneEQ functions.

Already have a calibrated measurement microphone? This is the interface on its own. If you need the mic as well, get the AMI Tuning Kit, which bundles this same interface with a Beyerdynamic MM-1 precision-calibrated microphone and calibration files.
