The Phase Checker allows fast testing of the polarity of acoustic transducers,
microphones and electronic devices. Sophisticated signal processing allows
fast and accurate determination of the absolute polarity unimpaired by passive
crossovers or signal waveform distortions produced by the device under test.

The test system consists of two units: the Signal Generator and the detector.

To check acoustical or electrical phasing, the Generator is connected to the input
of the device under test whereas the detector picks up the output signal. Subsequent
signal processing enables the detector to decide whether the device under test
reverses signal phase or not. The result of the test procedure is displayed via two
LEDS, the green one indicating the “in phase” and the red one indicating the “out
of phase” condition.

Due to the versatile Input/Output structure of both the Generator and the detector
any combination of acoustical and electrical input and output may be realized.
