FRS-1801 | 29
Overload Cursor – The overload cursor appears on the meter as an arrowhead in the meter scale. The two
pulldown boxes set the position of the overload cursor on the left and right meters. If the audio level on that
channel goes above the cursor, the Overload Counter at the top of the meter is incremented.
The Overload Counter shows a running count of the number of overloads
detected. The Overload level is shown by a marker beside the meter,
and its position can be set under the Meter Ballistics Config tab
The Phasemeter (located at the bottom of the RALM meter display) is a
small meter that represents the phase correlation factor between the two
channels of a pair.
Note – The level and phase meters are disabled for channels carrying
non-PCM audio (Dolby E, Dolby Digital or other non-PCM types).

with pulsed tone on left channel in every pair) to the
