The Gold Line Polarity Analyzer is an instrument for checking the polarity of speaker systems. It uses state-of-the-art signal processing to accurately determine absolute polarity, which is unaffected by passive crossovers or signal waveform distortions produced by the device under test. The Gold Line Polarity Analyzer works on tweeters, mid-ranges, woofers, subwoofer speakers and cabinets, equalizers, amplifier and crossovers. With this handy instrument an entire speaker system can be checked in only seconds.
