MICROPHONE CONNECTION

Unlike previous versions of the Phonic Personal
Audio series, the PAA3X has a detachable mi-
crophone that can be connected directly to the
unit or placed remotely through the 5 meter
extension cable.
When inserting the microphone into the micro-
phone slot, the release button must be facing the
front of the PAA3X, as shown below.
The mic is removed by pushing the release
button on the base of the microphone and slid-
ing it out.
Phonic have also included a 5 meter exten-
sion cable, as previously mentioned. This can
be used along with the mic stand adapter to
remotely place the microphone.

AUDIO ANALYSIS
On the following pages we will discuss the
various audio analysis functions that the PAA3X
provides. There are four main functions in total,
all of which are easily accessible through the
function menu. If at any point you wish to access
a new feature, simply use the controls to select
the function icon to bring up the function menu.

Real Time Analyzer (RTA)

This function analyzes the audio received
through either the built-in microphones or line in
connectors, divided into a number of separate
bands in 1/3rd or 1/6th octave resolution. Each
frequency band is graphed as a vertical bar on
the RTA, the height of which represents the level
– whether in dB SPL, dBu, etc – of the individual
octave or sub-octave bands. A 60 dB range is
displayed at any one time, and users can scroll
up the page slightly if clipping occurs, or scroll
down if the results aren't visible.
Frequencies from 20 Hz to 20 kHz can be
monitored individually by selecting the frequency
band on screen. The level and frequency will
appear to the left of the screen. Measurements
can be taken at four different response times
(35 ms, 125 ms, 250 ms, and 1 sec) and in four
weighting types (A weighting, B weighting, C
weighting and Flat). For more info on response
times and weighting, please consult the appro-
priate sections.
