The CRICKET polarity tester is great for PA Hire companies, musicians, DJs, Film, TV and Broadcast applications.

The purpose of the CRICKET is to test the polarity of a sound system each time it is used to ensure it is working properly.

Affordable and easy to use. The CRICKET is a must have for anybody working with sound systems.

Checks continuity and polarity
¼" TRS and XLR in/out
Tests speakers, mics, cables and wireless systems
Tests mixers and signal processors for polarity inversions
Internal speaker for testing mic polarity
Internal mic for testing speakers
High level output for testing miles of cable
Battery test on Receive module saves troubleshooting time

Reversed polarity plays 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.

Determines whether every component in an audio system from patch bay to console to speakers is in or out of polarity.

Tests balanced and unbalanced cables of up to 2,000 feet in length.

It will drive a multicore, and indicate which of a microphone's XLR connector pins is hot

Plug directly into a speaker cabinet and drive the components.

The Red and Green LED's can save hours of troubleshooting.

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 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.
