PAA3X
English
Polarity
The polarity function is most useful in determin-
ing whether a speaker is correctly wired. A polar-
ity signal is typically required when checking the
phase of a speaker. Thankfully, one is provided
through the PAA3X’s signal generator.
6. Activate the polarity function by highlighting
and selecting the PAA3X’s Run/Stop icon.
7. A large “+” appearing on screen means the
signal is in phase and the wiring is correct.
8. If instead of a “+” you get a “-”, the speaker
is out of phase and should be corrected.
9. A big “?” or a screen switching between plus
and minus symbols means the sound level is
too low and not detectable by the PAA3X. So
turn it up! The signal generator’s level can
be increased through the signal generator
menu, but you can also opt to turn up the
volume of your speaker/system.
Attention: Make sure the sound pressure level
of the polarity signal from the system is higher
than the noise from the surrounding environ-
ment. The PAA3X will not be able to detect the
phase of the speaker accurately if the polarity
signal is not at a suitable level.
The above procedure is for checking the polar-
ity of speakers. The same method can be used
to check the wiring of cables themselves, you
simply need to select the Line In as your input
source. After doing so, connect one end of the
cable you wish to check to your signal generator
and the other end to the PAA3X’s input. Points
6 through 9 above should be identical from that
point on.
Checking the polarity of speakers:
1.
Go to the Polarity function by accessing the
Function menu.
2. Go to the Settings menu and select Mic In as
your input source. Exit the Settings menu.
3. Connect the signal generator output to
your sound system’s inputs. Ideally, with
active speakers, you will connect the signal
generator directly to your speakers to avoid
the complication of finding miswired cables
elsewhere in your setup.
4. Start the polarity tone playing by turning the
signal generator on/off icon. You could also
opt to play a polarity signal through your
speakers using some other means (compact
disc, external tone generator, etc). For more
information on the signal generator, consult
the Signal Generator section of this manual.
5. Stand approximately one meter (3 to 4 feet)
in front of the speaker that plays the polarity
signal.
