FRONT PANEL CONTROLS

1 Main Power Switch: Press this button to
apply power to the AVR 4500. When the switch
is pressed in, the unit is placed in a Standby
mode, as indicated by the orange LED 3 sur-
rounding the System Power Control 2. T his
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.

2 System Power Control: When the Main
Power Switch 1 is “ON,” press this button to
turn on the AVR 4500; press it again to turn the
unit off (to Standby). Note that the Power
Indicator surrounding the switch 3 will turn
green when the unit is on.

3 Power Indicator: This LED will be illuminat-
ed 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 green.

4 Headphone Jack: This jack may be used to
listen to the AVR 4500’s output through a pair of
headphones. Be certain that the headphones
have a standard 6.3 mm stereo phone plug. Note
that the main room speakers and all Preamp
Outputs

b will automatically be turned off

when the headphone jack is in use.

5 Dolby Mode Selector: Pressing this selector
button cycles the AVR through the various Dolby
surround modes. The first press of the button
switches the surround mode to the last Dolby sur-
round mode that was in use.
Each subsequent press selects the next mode in
the following order:

Note that DOLBY DIGITAL mode is available only
with digital input selected and the other modes
only when a Dolby Digital source is not playing.

6 DTS Surround Mode Selector: When a
DTS source is in use the AVR 4500 will select the
appropriate mode automatically and no other
mode will be available. In that case, pressing that
button will display the mode currently selected
by the AVR´s decoder. Depending on the surround
material played and the speaker setting, one of
the following modes will be selected by the unit:

• DTS-ES 6.1 DISCRETE
• DTS-ES 6.1 MATRIX
• DTS + NEO:6
• DTS 5.1

Both DTS ES 6.1 Modes and DTS+NEO:6 will be
selected only when surround back speakers have
been configured with your system: DISCRETE
with appropriate source material, MATRIX with
6.1 Matrix recordings and DTS+NEO:6 with nor-
mal DTS 5.1 channel recordings. The DTS 5.1
mode will be selected with any DTS source, when
no surround back speakers are configured (see
also pages 24 and 32-35).
