Surround Mode Indicators: One of these indicators will light
to show the surround mode in use. Depending on the specific
combination of input sources and surround mode selected, more
than one indicator may light. See the
Main Room Operation/
Surround Mode Selection
and Digital Audio Playback sections
for more information.
Upper Display Line: Depending on the unit’s status, a variety
of messages will appear here. In normal operation, this line will
show the current input source and identify whether an analog or
digital input is in use. When the tuner is selected as the input, this
line will identify the station as AM or FM, and show the frequency
and preset number, if any.
Lower Display Line: Depending on the unit’s status, a variety
of messages will appear here. In normal operation, the current
surround mode will appear on this line.
Speaker/Channel Input Indicators: These indicators are
multipurpose, indicating both the speaker type selected for each
channel and the number of audio channels available. The speaker
indicators light as a single outline around the speaker position
indicator when a “small” speaker is selected and as a larger icon
with three connected boxes when “large” speakers are selected.
When only the speaker position letters appear, no speaker has
been assigned to that position. See the
AVR21EN Configuration/
Speaker Setup
section for more information on configuring speakers.
The letters inside each box also indicate the active input channels.
For standard analog inputs, only the L and R will light, indicating a
stereo input. For a digital source, the indicators will light to display
the channels being received at the digital input. When the letters
flash, the digital input has been interrupted and an
UNLOCK
message may appear in the Lower Display Line . See the
AVR21EN Front Panel Information Display Features/Speaker/
Channel Input Indicators
section for more information on the
Channel Indicators.
Input Indicators: One of these indicators will light to identify
the currently selected input. Note that the entire list will light
briefly each time the unit is turned on, as a test.
