Interpreting the Surround Sound Display
The Surround Sound display indicates the audio level balance among the left (L), right (R),
The cyan polygon formed by connecting the level indicator endpoints shows the total sound volume formed by the L, R, Ls, and Rs channels. This connecting line will bend away from the center if the two signals have a positive correlation, will bend towards the center if the signals have a negative correlation, and will not bend if the signals are uncorrelated.
The Center Volume indicator displays the sound volume of the center channel as a vertical yellow bar between the L and R channels, and connects the ends of the L, C, and R audio level indicators with straight lines.
Phantom Sound Indicators (PSI), located on each side of the Surround Sound display, indicate the location of potential phantom sound sources formed by adjacent channels. The white tic marks on these moving bar indicators show the phantom source locations. The bar length indicates the correlation between the adjacent channels. A
A fifth PSI at the top of the display shows potential phantom sources formed by the LC channel pair and the CR channel pair. If the L, R, and C channels all have the same signal level, the white tic mark on the bar will appear directly above the C level indicator. The white tic mark will move right or left depending on the relative balance between the three channels. A short bar to the left of the white tic mark indicates a positive correlation between L and C. The bar will grow as the correlation decreases. Like the
45 _ angle for negative signal correlations. The bar to the right of the white tic mark behaves in the same way, depending on the
