The following section contains information
concerning acoustic analysis, and illustrates how
to use the PAA3 to measure various properties of
your audio.
RTA (Real Time Analyzer) - Accoustic
This function analyzes the audio received through
either the built-in mic or Line In connection, divided
into 31-bands at 1/3 octave intervals, and displays
the relevent information on a bar graph that shows
the decible level of each band of sound from 20 Hz
to 20 kHz in four different response times (35 ms,
125 ms, 250 ms, and 1 sec) and in three weighting
types (A weighting, C weighting and Flat). For
more info on response times and weighting,
please consult the appropriate sections.
Beneath you will nd two readouts: the
numbers in the left column display the
frequency while the numbers in the right
column display the frequency levels. The
graphic shown indicates that the user has set
the level range at 50~110 SPL, A weighting.
The max level during the time of measurement
is 105.5 dB, The user is reading at 1 kHz,
which has a dB SPL of 102.8. If you would like
to store the measurement data in the memory
of PAA3, go to the STORE menu. Users can
save the measured spectrum data into one of
the ten memories. Please refer to MEMORY/
STORE for more information.
5. Scroll through the various values located in
the 'Hz' box until you come to a ashing ESC.
Press enter to exit RTA mode.
SPL (Sound Pressure Level) Meter
This feature of the PAA3 gives users an accurate
measurement of the overall "loudness" of their
sound, measured in decibels (dB). This is a true
RMS-measurement, using standard display time
average, and standard A, C, and Flat weightings.
Procedure:
1. After the start up sequence of the PAA3 is
complete, the real time analyzer will appear on
the LCD screen.
2. Go to the SETTING menu to set the
appropriate weighting, level range, response
time, or other relevant properties.
3. Select VALUE from the main menu to enter
RTA mode.
4. Press ENTER to freeze measurement data.
Press ENTER again on the highlighted VALUE
to view the value of each center frequency.
5. Use the LEFT/UP and RIGHT/ DOWN buttons
or simply scroll the JOG control to view the
level of dB SPL in real-time for the center
frequency of all 31 bands. The default readout
is the ALL FREQUENCY level.
page 10
PAA3 User's Manual PHONIC CORPORATION
Procedure:
1. Enter the SPL/LINE menu and set the
measurement unit to SPL.
2. You may select a range level, weighting,
response time or a maximum level by going
into the SETTINGS menu, then onto the
appropriate menus. The selected values of
these options will be displayed above the RTA
on the PAA3's default screen.
3. On the main RTA display, hold the ENTER
button for approximately 2 seconds to activate
the SPL screen. Press the ENTER button
once to exit.
NB. You can easily refresh the Max SPL value
by holding both the ← left and → right keys
simultaneously for at least one second.
RT60 (Reverb Time Analyzing)
The RT60 function of the PAA3 is easy enough
to understand: it is basically the time it takes for
a signal to drop 60 dB. Getting the average of
many different RT60 calculations from around a
room allows users to get an idea as to how much
absorption or reection of audio the room provides.
Depending on your needs, you may wish to have
a high or low RT60 measurement. For example,
for public speaking, an RT60 measurement of
less than 1 second is preferable, as to have a
clear, concise voice conveyed to the audience.
With choirs or instrumental music, an RT60
measurement of greater than 1.5 seconds may be
appropriate. It all depends on your needs.
Measuring Reverb Time:
1. Press enter to open the main menu and select
“RT60.”
2. Simply click “RUN” to get your RT60 reading.
3. The PAA3 will wait for a signal greater than 30
dB over the background noise level (detected
prior to the measurement). A little helpful hint:
the louder the test signal, the greater accuracy
of your RT60 calculation.
4. Play the pink noise from the included CD
through your audio system. Slowly move the
master fader up, to a point where the audio
level received by the PAA3 is greater than 30
dB. Quickly mute the system to get your RT60
reading as accurate as possible.
5. After the measurement is taken, the RT60
measurement will appear onscreen.
PHONIC CORPORATION PAA3 User's Manual

Accumulation:
Users are able to accumulate various RT60 calculations by pressing enter while the “ACxx” (where
xx equals the number of accumulated values) option is highlighted. Up to 30 measurements can be
accumulated. When RT60 measurements are accumulated, the average of said memories is automatically
taken and displayed onscreen. After 30 memories have been accumulated, users will be forced to store
their data, or else lose it.
AC 01
Store:
Storing the results of RT60 measurements is simple. First highlight the STO option
and push ENTER. When the store page comes up, choose one of the memory

as humans. Generally, the sensitivity of human
hearing is restricted to the frequency range of
20 Hz to 20 kHz. The human ear, however, is
most sensitive to sounds in the range of 500 Hz
to 8 kHz. The ear becomes progressively less
sensitive to sound out of this range.
To account for this limitation of human hearing,
many audio analyzers, including the PAA3,
incorporate a ltering of acoustic signals according
to frequency. This ltering (weighting type) is
devised to correspond to the varying sensitivity of
the human ear to sound over the audible frequency
range. The PAA3 comes with both A-weighting and
C-weighting standardized by the ANSI (American
National Standards Institute). A-weighting is
the most frequently used weighting type and is
used for measuring lower sound levels, while C-
weighting is best suited for higher sound levels.
The user can set the weighting for measurements
in dBu, dBV or voltage.
Procedure:
1. Go to the SETTING/ WEIGHTING menu.
2. Select an appropriate weighting for the
measurement. A tick appears next to your
selection.
3. Press ESC to the previous menu.
Level Range
The PAA3 has three different ranges for
measurements in SPL, dBu, dBV and voltage.
SPL: 30 ~ 90 / 50 ~ 110 / 70 ~ 130
dBu: -50 ~ +10 / -35 ~ +25 / -20 ~ +40
dBV: -52 ~ +8 / -37 ~ +23 / -22 ~ +38
VAC: 5m ~ 2.45V / 14m ~ 14V / 77.5m ~ 80V
Procedure:
1. Go to the SETTING menu, and proceed onto
the LEVEL RANGE menu.
2. Select an appropriate level range for your
measurement and press the ENTER button.

Calibration
You should never actually need to calibrate your
PAA3. If measurement data or operation of the
unit is abnormal, however, it may be necessary
to. Anyone can calibrate the PAA3 and regain
accurate sound pressure level measurement by
using a sound level calibrator with 1/2” diameter
adapter that sends out a 1 kHz tone. A B&K TYPE
4231 sound level calibrator is suggested.
Procedure:
1. First, turn the PEAK HOLD OFF and set the
RESP TIME (response time) to 250 ms.
2. Place a sound level calibrator with a
microphone connector of a 1/2” diameter close
to the PAA3's built-in mic.
3. Enter the SETTING menu and activate the
function.
4. Adjust the level measured from the SPL
calibrator by pressing UP/DOWN buttons until
the level is equal to that of the sound level
calibrator (typically 94 dB). Pressing the UP
button each time will increase the value by
0.1dB; pressing the DOWN button each time
will decrease by 0.1 dB.
5. Press the ENTER button to complete the
calibration and to return to RTA display.
ATTENTION: If you want to cancel calibration, simply
press the ENTER button to exit before making any
adjustment. To resort the default calibration, simply adjust
the offset value to 0.0 dB.
PHASE CHECK
Measuring the phase of a signal allows you to
gure 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 (or play the included PAA3 CD
through your system).
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.

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.
POWER
To follow the correct power-down procedure is
quite important to the PAA3. The easiest way to do
so, however, is to hold the POWER / BACKLIGHT
button of the PAA3 for approximately 2.5 seconds.
The device will automatically shutdown. If that’s
too easy, and you prefer to do things the difcult
way, you may also do one of the following:
Procedure:
1. Enter the POWER menu.
2. Select AUTO OFF, and the PAA3 will
automatically shut itself down after being left
idle for 15 minutes.
Procedure:
1. Connect the PAA3 to your audio system via
the XLR-male connector on the bottom of the
device.
2. Go into the GENERATOR menu and select
one of the signal to activate.
3. Selecting MANUAL OFF will disable AUTO
OFF mode, and ensure the PAA3 will not shut
itself down automatically, unless the batteries
are low.
4. Select OFF, and the PAA3 will immediately
shut down, saving all of your settings and
measurement data before hand.
3. Select ESC to return to previous menu or
press OFF to cancel.
