LMS electroacoustic tester is a complete and reasonably priced electroacoustic analysis system suitable for practical electroacoustic engineering applications, providing high-quality measurement data. LMS is an ideal tool for development and testing, whether used in professional audio systems, home audio systems, car audio systems, or contracted audio engineering. The system consists of an ISA expansion card, RS232 interface cable, and a calibrated M31 microphone. Support WIN XP WIN7、 WIN10、WIN11， Can be used for speaker design and development, as well as various general electroacoustic measurements. The characteristics of LMS include:

No need for expensive soundproof rooms, reducing usage costs.

Accurate data post-processing and management facilitate data organization and analysis.

The basic frequency range is from 10Hz to 100kHz, meeting a wide range of frequency requirements.

Adopting a bistable adjustable tracking filter, it provides several response measurement methods including flat, low-pass, high pass, band-pass, and bandstop.

The rich graphical user interface enhances the convenience of operation and system functionality.

Support manual frequency scanning, with a scanning accuracy of up to 800 points, meeting high-precision measurement requirements.

Powerful post-processing and directional polar coordinate display provide more intuitive data analysis.
