Phase Check; Generator - Phonic PAA3 Manual Del Usuario

PHASE CHECK

Measuring the phase of a signal allows you to figure out
whether a speaker is correctly wired. A polarity signal is
usually needed when checking the phase of a speaker or
ensure that an output connection is correct.
Procedure:
1. Go to the SPL/LINE and select dBu to check a
device's output connection or SPL to check a
speaker's wiring.
2. Go to the SETTING menu, and select POLARITY.
3. If checking speaker wiring, stand one meter in front
of the speaker that plays the polarity
signal, go to the PHASE CHECK
menu and activate.
4. A large "+" appearing on screen means
the signal is in phase, and the wiring
is correct.
5. If instead of a "+" you get a "-", the
speaker is out of phase and should
be corrected.
6. A big "?" or a screen switching
between plus and minus symbols
means the sound pressure level is at
a level that is not detectable by the
PAA3. So turn it up!
ATTENTION: Make sure the sound pressure level of
the polarity signal from the system is louder than the
environment noise, otherwise the PAA3 will not be able to
detect the phase of the speaker.
PAA3

GENERATOR

The PAA3 can send out pink noise, a polarity signal, and
a 1 kHz tone, all of which is sent out via the Male XLR
connector (on the bottom of the PAA3) to any external
system, at a level of -10 dBu.
Tones:
Pink noise: mostly used for acoustic environment
adjusting. For example: sound system equalization.
Polarity: often used to check the phase of
speakers.
1 kHz tone: a widely used among the professionals
for audio signal testing.
