Pressing the Mute button allows you to step through three mute
states and an unmuted state. When the system is in one of the
mute states, all other information normally shown in the LCD such
as the
Input Status Display is disabled. In addition, all other
buttons are disabled until you unmute the system. See Table 3–2
below.
Muting functions affect the signals to the speakers, headphones and the
rear panel
Selected/Downmix Analog Output
connectors. Muting
does not affect the Metered Analog Ouputs except to defeat scaling.
These outputs reamain active even when the mute state is enabled.
Phase Correlation
1. Pressing the
φ
button displays the phase correlation indicator in
the LCD screen.
The average correlation (phase) for the signal going through the left
speaker compared to the signal going through the right speaker is
indicated by a stationary block appearing in one of three positions on
the second line of the screen. A moving block indicates an
instantaneous (short term sample) phase correlation. Each of the three
positions has a different meaning.
• Center : Only one channel active, or zero (0) correlation between the
two channels
• Left (-) : Selected channels are out-of-phase (-1 correlation
maximum)
• Right (+) : Selected channels are in-phase (+1 correlation
maximum).
