Meter
The meter function can take calculations in dB
SPL (through the detachable microphone), dBu,
dBV or Volt (through the line inputs). The SPL
function provides users with the overall ‘loud-
ness’ of their input signal and can be accessed
by simply selecting ‘Mic In’ as the desired input
source. The dBu, dBV and Volt measurements
can be taken through the line inputs, where the
meter function will give visual representations of
their respective levels.
Taking line input measurements:
1. Enter the Settings menu through the Main
menu and set your input source to “Line.”
You can also select your desired measure-
ment unit from dBu, dBV and Volt.
2. You may select a response time, weighting,
or peak hold time. Push “OK” to close the
settings menu.
3. Connect a source signal into the PAA3X’s
line inputs.
4. Select the RUN/STOP icon to start the level
meter.
5. Reset the Maximum level by highlighting and
selecting the word “Max” on screen.
6. If the level meter clips, it may be necessary
to adjust the measurement range. This is
done by simply clicking the range values
on the level meter itself. The measurement
range will depend on the unit selected in the
settings.
Each unit type has three dierent ranges that
can be selected.
When operating under dBu, the range can
be adjusted between -85 to -20 dBu, -75 to
-5 dBu, -60 to 10 dBu and -45 to 25 dBu.
When dBV is selected as the unit, the range
is selectable between -87.2 to -22.2 dBV,
-77.2 to -7.2 dBV, -62.2 to 7.8 dBV and -47.2
to 22.8 dBV.
Under voltage, you can select 43.6u to
77.4mV, 0.14m to 435 mV, 0.78 to 2.45V or
4.36m to 13.7V.
Taking SPL measurements:
1. Enter the Settings menu within the Main
menu.
2. Select “Mic” as your input source. The unit
will automatically be set to dB SPL.
3. Also in the settings menu, users can choose
the response time, weighting and peak hold.
4. Return to the meter by clicking “Exit”.
5. A 60 dB range is visible on screen at any time.
Users can view 30 to 100 dB SPL, 45 to 115
dB SPL or 60 to 130 dB SPL. To change the
range, simply the range icon to the right of
the screen.
6. Reset the Maximum SPL level by simply
highlighting and selecting the word “Max” on
screen.
