SIGNAL GENERATOR
The PAA3X's signal generator can be accessed
at any time, for any function. There are four
built-in signals, each with their own adjustable
properties. All generated signals can have their
output level adjusted between -50 dBu and +4
dBu. All signals – except the sweep signal – can
also have their gate time adjusted, where users
can select a time up to 10 seconds for the signal
to run, at which time the signal will turn off.
Sweep: The sweep signal consists of a sine
wave with an ever-changing frequency. The
frequencies can be user-defined, with 1/6, 1/3,
2/3 and 1 octave intervals selectable by the
user. Alternatively, users can choose 'Select'
and adjust the sweep range manually. Once
users choose 'Select', the Sweep signal's "Start"
and "Stop" fields will become active. Users can
select the start frequency (between 20Hz and 20
kHz) and stop frequency (between 20 Hz and
20 kHz). Users can opt to have a continuous
sweep tone, where the signal generator will run
through the entire audio spectrum selected, then
start again. Alternatively, users can opt for the
tone to repeat itself anywhere between 1 and 10
times before it turns off.
Sine: Used for a variety of purposes. A 1 kHz sine
wave is perhaps the most commonly used sine
wave. However, users can adjust the PAA3X's
sine wave to a number of frequencies between
20 Hz and 20 kHz.

Polarity: The polarity signal is commonly used for
checking the polarity of speakers. Check the Po-
larity section of this manual for more information.
Pink Noise: The pink noise signal is typically
used for adjustment of environmental acoustics.
The most common use would be in the setting of
equalizers. As pink noise encompasses most fre-
quencies audible to humans, playing a pink noise
signal in any given setting can give engineers a
sense of the acoustical properties of the room
and allows them to compensate through the EQ.
UTILITY
The Utility menu can be found within the PAA3X's
main menu. Within are some basic settings for
the unit.
Calendar: Users can adjust the date here.
Time: Change the time (in 24 hour time).
Display Brightness: Users can adjust the
brightness level through this function. Reducing
the brightness of the screen can help preserve
battery power, or increasing it can enhance vis-
ibility in bright areas.
Display Backlight: The backlight time option
allows users to adjust the time they wish the
PAA3X's screen to remain on. After the selected
time has passed, the screen will go dark to pre-
serve the battery power. Adjusting the backlight
option to 'off' will disable this feature.
Battery Remain Power: Users can monitor the
current remaining battery life here.
