MainStage MultiMeter Correlation Meter
Correlation Meter gauges the phase relationship of a stereo signal.
Correlation Meter scale values indicate the following:
• A +1 correlation value indicates that the left and right channels correlate 100%. In other
words, the left and right signals are in phase and are the same shape.
• Correlation values to the right of the center position indicate that the stereo signal is
mono compatible.
• The middle position indicates the highest allowable amount of left/right divergence,
which is often audible as an extremely wide stereo effect.
• When the Correlation Meter moves to the left of the center position, out-of-phase
material is present. This leads to phase cancelations if the stereo signal is combined
into a mono signal.
MainStage MultiMeter Peak parameters
MultiMeter offers common Peak parameters for the Analyzer and Goniometer metering
tools. The Level and Correlation meters have discrete Peak parameters. See MainStage
MultiMeter Level and Loudness Meters.
MultiMeter Peak parameters
• Peak pop-up menu: Choose the hold time for all metering tools. Choose 2, 4, or 6
seconds—or infinite.
Note: The (Peak) Hold button must be turned on for the selected time value to have an
effect.
• Hold button: Turn on peak hold for all metering modes in MultiMeter. This is displayed in
the following ways:
• Analyzer: A small segment above each 1/3-octave level bar indicates the most recent
peak level.
• Goniometer: All illuminated pixels are held during a peak hold.
• Reset button: Reset the peak hold segments of all metering tools.
