The Gold Line Polarity Analyzers utilize state of the art signal processing to accurately determine absolute polarity which is unimpaired by passive crossovers or signal waveform distortions produced by the device under test.
The APT2 works on tweeters, mid-ranges, woofers, subwoofer speakers and cabinets, equalizers, amplifiers and crossovers.
With this handy instrument an entire speaker system can be checked in only seconds.
The Polarity Detector (APT) and Pulse Generator (PG) are supplied as separate units.
U.S. PATENT 5,319,714
