FRONT PANEL CONTROLS
Main Power Switch: Press this button to
apply power to the AVR 500. When the switch
is pressed in, the unit is placed in a Standby
mode, as indicated by the amber LED 
3 sur-
rounding the System Power Control
2.
This button MUST be pressed in to operate the
unit. To turn the unit off 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: In normal operation this switch is left in
the “ON” position.
System Power Control: When the Main
Power Switch 
1 is “ON,” press this button
to turn on the AVR 500; press it again to turn
the unit off. Note that the Power Indicator
surrounding the switch 3 will turn green
when the unit is on.
Power Indicator: This LED will illuminate
in amber 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 green.
Headphone Jack: This jack may be used to
listen to the AVR 500’s output through a pair of
headphones. Be certain that the headphones
have a standard 
1
/
4
" stereo phone plug. Note
that the main room speakers will automatically
be turned off when the headphone jack is in use.
Bass Control: Turn this control to modify the
low-frequency output of the left/right channels by
as much as ±10dB. Set this control to a suitable
position for your taste or room acoustics.
Treble Control: Turn this control to modify
the high-frequency output of the left/right chan-
nels by as much as ±10dB. Set this control to a
suitable position for your taste or room acoustics.
Balance Control: Turn this control to
change the relative volume for the front
left/right channels.
NOTE: For proper operation of the surround
modes this control should be at the midpoint 
or “12 o’clock” position.
