Measurement Functions

polarity

The polarity test function detects the correct cable and speaker polarity

in combination with the Minirator. The Minilyzer provides the following

test configurations:

a. Speaker polarity test

Fig 3.12 Speaker Polarity Panel

Fig 3.13 Woofer Polarity Panel

Feed the speaker system

with the polarity-test signal of

the Minirator and adjust the

level (at Minirator or amplifier)

that the test signal is good

to hear.

Minilyzer settings:
• IN:MIC (INT), using the

internal mic of the Minilyzer

ML1

• IN:XLR/RCA, using an

external mic, such as the

MiniSPL

Choose the polarity test

frequency range:
• FULL/MID, for tests with

wide band speakers

• WOOFER, for tests with

woofers

Note:

Please note the polarity testing is a simplified

measurement of a very complex signal phasing.

Drivers, speakers and cross-overs cause severe

phase shifts of the audio signal.

The polarity of various speakers within the same

cabinet can be different. This is not a problem nor

caused by bad speaker design.

Polarity testing is useful for checking the correct wiring

of similar speaker systems.
