Phase-it

Correct polarity? Gato Audio is offering a simple but efficient tool for the loudspeaker developer, manufacturer and for the DIY and car stereo enthusiast; the loudspeaker polarity detector Phase-it.

A problem solver

It’s a common problem when you design a crossover in a large and complex system, that a driver easily is connected with the wrong phase polarity. This could cause a lot of wasted time, but with the Phase-it, it’s now possible to check every single driver in just a blink of an eye (which is quite fast).

The measuring technique behind Phase-it

The Phase-it operates by sending a harmless electrical pulse into the speaker. The built-in microphone detects the reproduced acoustic pulse and illuminates an LED green or red; green for correct polarity and red for reversed polarity. This makes the Phase-it especially well suited for difficult accessible or hidden speakers, for instance built into the door of a car.
