Main Power Switch: Press this button to
apply power to the AVR. When the switch is
pressed in, the unit is placed in a Standby
mode, as indicated by the orange LED
2
. This
button MUST be pressed in to operate the unit.
To turn the unit off completely and prevent the
use of the remote control, this switch should be
pressed until it pops out from the front panel
so that the word “OFF” may be read at the top
of the switch.
NOTE: This switch is normally left in the “ON”
position.
1
System Power Control: When the Main
Power Switch is “ON,” press this button to
turn on the AVR; press it again to turn the unit
off (to Standby). Note that the
Power
Indicator
2
will turn blue when the unit is on.
2
Power Indicator: This LED will be illumi-
nated in orange when the unit is in the Standby
mode to signal that the unit is ready to be
turned on. When the unit is in operation, the
indicator will turn blue.
3
Headphone Jack: This jack may be used to
listen to the AVR’s output through a pair of
headphones. Be certain that the headphones
have a standard 6.3 mm stereo phone plug.
Note that the speakers will automatically be
turned off when the headphones are connected.
4
Digital Optical 3 Input: Connect the opti-
cal digital audio output of an audio or video prod-
uct to this jack. When the Input is not in use, be
certain to keep the plastic cap installed to avoid
dust contamination that might degrade future
performance.
5
Speaker/Channel Input Indicators: These
indicators are multipurpose, indicating either the
speaker type selected for each channel or the
incoming data-signal configuration. The left, cen-
ter, right, right surround and left surround speaker
indicators are composed of three boxes, while the
subwoofer is a single box. The center box lights
when a “Small” speaker is selected, and the two
outer boxes light when “Large” speakers are
selected. When none of the boxes are lit for the
center, surround or subwoofer channels, no
speaker has been selected for that position. (See
page 16 for more information on configuring
speakers.) The letters inside each of the center
boxes display active input channels. For standard
analog inputs, only the L and R will light, indicat-
ing a stereo input. When a digital source is play-
ing, the indicators will light to display the chan-
nels begin received at the digital input. When the
letters flash, the digital input has been interrupt-
ed. (See page 20 for more information on the
Channel Indicators).
