Fast and efficient tool for verifying the polarity of loudspeakers
Works perfectly with individual drive units and with individual drivers in a multi-way boxed speaker system
Clear indication of each drivers polarity and function for fast troubleshooting Auto power off for long lasting battery time
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 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.
Here are a few organizations / persons who currently uses Phase-it in their speaker production:
