Using the MultiMeter’s Level Meter
The Level Meter displays the current signal level on a logarithmic decibel scale. The signal
level for each channel is represented by a blue bar.
RMS and Peak levels are shown simultaneously, with RMS levels appearing as dark blue
bars and Peak levels appearing as light blue bars. When the level exceeds 0 dB, the portion
of the bar above the 0 dB mark turns red.
Current peak values are displayed numerically (in dB increments) above the Level Meter.
Click in the display to reset peak values.
Using the MultiMeter’s Correlation Meter
The Correlation Meter gauges the phase relationship of a stereo signal. The Correlation
Meter’s 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 in the blue zone (between +1 and the middle 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 into the red area to the left of the center position,
out-of-phase material is present. This will lead to phase cancelations if the stereo signal
is combined into a mono signal.
