18.5.1 Understanding Resolution, Peak Overload
Resolution
Sound recordings are saved with 16-bit resolution which provides a
measurement range of about 90 dB. This means that the 831C is
capable of recording sound signals with amplitudes no more than 90
dB below the level at which the selected range will overload.
Peak Overload
The 831C will calculate the peak overload based on the current
microphone type. To ensure the correct settings, navigate to
Tools
Calibrate
Settings
, and see

831C
.
Next, the 831C automatically calculates the sound recording range
based on the Peak Overload value. Additionally, setting the
Gain
at
either 0 dB or 20 dB (
Menu
Setup Manager
SLM
) and selecting
either Normal or High Range (
Menu
Setup Manager
Sound
) will
result in different values of upper and lower limits for any given
microphone. The current Peak Overload value displays on the calibrate
tab as shown in
Figure 18-6 Peak Overload
.
