STATUS MENU LEVEL METERS
Most STATUS menus contain level meters that indicate fluctuating
input levels in the front left (L), center (C), front right (R), surround left
(SL), surround right (SR), surround back (SB) and subwoofer (SUB)
channels. These level meters indicate input levels for both analog and
digital input sources. For instance, the level meters indicate digital
audio input levels when a digital audio source is present.
Different combinations of level meters appear on each STATUS
menu, depending on the source that is present. The SB level meter
appears when a 6.1-channel source is present, or when a 5.1-chan-
nel source is present and the ES DECODING parameter is set to ON.
Level meters appear in combinations of green, yellow and red
when the on-screen display is configured for a blue-screen back-
ground. Green indicates low levels, yellow indicates normal levels,
and red indicates high levels and the onset of overload. Level
meters appear in white when the on-screen display is not config-
ured for a blue screen background.
