•
Integration Time (LKFS) A-D - Adjust the integration time for each of the meters.
Default is 3 seconds, 10 seconds, 30 seconds, and 10 seconds for meters A-D.
•
ITU Gating Level - Sets the threshold below which the meter automatically pauses.
Default is -70dB. This is essentially a silence gate. Be careful not to adjust too low
as it will remain ungated due to noise, and likewise setting too high may cause too
much gating thus affecting the overall measurement.
•
ITU Gate Time Limit - Sets a "hold-off" time (i.e. hysteresis) to prevent unneces-
sary gate opening/closing.
•
Loudness Meter: Run/Stop - Allows starting/stopping (pausing) meter. This can
also be controlled via GPI.
•
Peak Hold Time - Sets how long the peak meter will hold the last peak value. De-
fault is 5 seconds.
•
Scroll Interval - Sets how fast the histogram will scroll from left to right. Note that
it acts like a "zoom" control and only on subsequent loudness values. The time be-
tween the horizontal ticks remains at 5 seconds.
•
Apply Loudness Measurement - Apply the automatically calculated difference be-
tween the loudness measured by the "D" LKFS meter and the target value as an
offset to Input Gain. Note that this can be done automatically by pressing the F3
front panel key when GPI is enabled.
•
Reset Loudness Measurement - Clears the integrator for all meters, does not reset
Input Gain. Note that except for a setting of Infinite, all integrators are self-clear-
ing once their time elapses (so about 30 seconds for an integration time of 30 sec-
onds).
•
Reset Peak Hold - Resets the value shown in the numeric Peak indicator.
•
Screenshot to USB - Copies the current screen to a timestamped file and stores it
to an installed USB thumb drive.
RTA Options:
•
1/3 octave/1/6 octave - sets the analyzer to 30 bands or 60 bands. Typical mea-
surements require only 1/3 octave resolution.
•
RTA Source - Select the input for the RTA
•
Target Level - Adjusts a horizontal target line, used for display only
•
Averages - Sets the averaging for the RTA. Lower averaging results in a faster dis-
