The Neutrik Test Instruments RT-2M is a 2-channel analog audio frequency generator and analyzer built for high-speed production testing and quality control. It automates audio and acoustical measurements across multiple applications—from amplifiers and consumer audio to microphones, speakers, and communication devices—eliminating subjective assessment methods. The instrument captures and analyzes incoming signals against QC tolerances in real-time, returning results to a controlling PC. Complete performance tests of essential audio parameters execute simultaneously, often in under one second, with reconfigurable test setups for evolving production needs.
Technical Specifications
The RT-2M operates as a 2-channel system with dual analog output and input capability, plus built-in microphone power supply. Multitone signal processing handles digitized data in blocklengths of 512, 1024, 2048, or 4096 samples, supporting both real-time analysis and post-processing of recorded signals. The platform accommodates a wide range of test signal types including stepped sweep, chirp analysis, and multitone configurations. PureSound™ technology ensures correlation with human ear perception.
