Polarity. It's not something you spend much time thinking about, but if it's off in your system, it causes all kinds of problems. Galaxy Audio's Cricket Polarity Test Set lets you check everything from wireless microphones, mixers, effects devices, amps, cables, and speakers, making sure everything's jiving together. But let's not confuse polarity with phase. When phase is inverted, it's possible to have only a partial signal being cancelled out. However, with polarity issues - no matter what distance or time relationship - the certain frequencies will just disappear. Polarity is either in or out - there is no middle ground.
