The Cricket can test the polarity of wireless microphones, mixers, effects devices, amps, cables and speakers. Polarity, should it become reversed, can play havoc with a sound system. If two sources are emitting the same electrical or acoustic tone (frequency), and one of those sources is in a state of inverted polarity, those tones, when combined at a given point, will cancel each other. While cancellation does not always indicate a complete loss of all sound, it does result in diminished sound quality. Unlike phase, polarity, at all distances and times, is either in or out. It's absolute. Galaxy Audio's battery powered Cricket Polarity/Continuity Test Set makes it easy to determine whether every component in an audio system - from patch bay to console to speakers - is in or out of polarity. The Cricket tests balanced and unbalanced cables of up to 2,000 feet in length. It will drive a "snake" (even one with transformers), and indicate which of a microphone's XLR connector pins is hot. A glance at the Cricket's red and green LED's can save hours of trouble shooting. No wonder it's an indispensable tool for sound system owners, operators and installers.
