 The
CRICKET polarity tester is great for sound contractors, musicians, DJs,
and many others. 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. This severely alters the sound of a system.
Polarity can be reversed while soldering cables, adding components to a sound system, reversing 'Banana' plugs, or
replacing a component in a speaker cabinet improperly, to name a few instances. The purpose of the CRICKET is to
test the polarity of a sound system each time it is used to insure it is working properly.
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. The CRICKET can also plug
directly into a speaker cabinet and drive the components. A glance at
the CRICKET's red and green LED's can save hours of troubleshooting. No
wonder it's an indispensable tool for sound system owners, operators,
installers, and sound rental companies.
The
CRICKET Polarity Tester is a two-piece unit ('Send' & 'Receive').
The Send unit generates a 'pulse', which is sent through the speaker,
cable, microphone, or the device being tested. The Receive unit
interprets that pulse and indicates if that pulse is positive or
negative. The bottom of each unit has a quick reference guide on how to
understand the readings given. The CRICKET Polarity Test Set is easy to
use, necessary to own, and not a lot of money. The CRICKET is suggested
for anybody working with sound systems.
