Depending on the chosen surround format, a number of points that indicate speaker
positions are shown (L, R, C, Ls, Rs in a 5.1 configuration is displayed in the figure). Lines
connect these points. The center position of each connecting line is indicated by a blue
marker.
A gray ball indicates the surround field/sound placement. As you move the surround
panner of the channel strip, the ball in the Correlation Meter mirrors your movements.
The blue markers also move in real time, with shaded gray lines indicating the divergence
from the centered positions on each of the connecting lines.
The LFE channel Correlation Meter is shown at the bottom of the main display. The
horizontal area around the white correlation indicator denotes phase correlation deviations
in real time. This is shown in both directions. A vertical red line to the left of the correlation
indicator shows the maximum negative phase deviation value. You can reset this line by
clicking it during playback.
The LFE Correlation Meter’s scale values indicate the following:
• A +1 correlation value indicates that the signal is balanced.
• Correlation values in the blue zone (between +1 and the middle position) indicate that
the signal is mono compatible.
• The middle position indicates the highest allowable amount of channel divergence.
• When the meter moves into the red area to the left of the center position, out-of-balance
material is present.
Surround MultiMeter Peak Parameters
The Surround MultiMeter offers the following Peak parameters:
• Hold button: Activates peak hold for all metering tools in the Surround MultiMeter, as
follows:
• Analyzer: A small yellow segment above each level bar indicates the most recent
peak level.
• Goniometer: All illuminated pixels are held during a peak hold.
• Level Meter: A small yellow segment above each level bar indicates the most recent
peak level.
• Balance/Correlation Meter: The horizontal area around the white correlation indicator
denotes phase correlation deviations in real time, in both directions.
Note: This meter must be manually opened by clicking the Balance/Correlation button.
