Operation

Basic Operation

Once you have completed the setup and configu-
ration of the AVR, it is simple to operate and
enjoy. The following instructions should be
followed for you to maximize your enjoyment of
your new receiver:
Turning the AVR On or Off
• When using the AVR for the first time, you must
press the Main Power Switch 1 on the front
panel to turn the unit on. This places the unit in a
Standby mode, as indicated by the amber color of
the Power Indicator 3. Once the unit is in
Standby, you may begin a listening session by
pressing the System Power Control 2 or the
Source button % on the front panel or the
B. Note that the Power
AVR Selector
Indicator 3 will turn blue. This will turn the unit
on and return it to the input source that was last
used. The unit may also be turned on from Standby
by pressing any of the Source Selector buttons
BCD or
on the remote
the Source button % on the front panel.
To turn the unit off at the end of a listening
session, simply press the System Power
Control 2 on the front panel or the Power
A on the remote. Power will

be shut off to any equipment plugged into the
rear panel Switched AC Outlets
Power Indicator 3 will turn orange.
When the remote is used to turn the unit "off" it
is actually placing the system in a Standby mode,
as indicated by the orange color of the Power
Indicator 3.
When you will be away from home for an
extended period of time it is always a good idea
to completely turn the unit off with the front
panel Main Power Switch 1.
NOTE: All preset memories may be lost if the
unit is left turned off with the Main Power
Switch 1 for more than two weeks.
Using the Sleep Timer
• To program the AVR for automatic turn-off, press
the Sleep Button on the remote. Each press
of the button will increase the time before shut
down in the following sequence:
90 80 70 60 50
min min min min min
40 30 20 10
OFF
min min min min
The sleep time will be displayed in the Lower
Display Line ˜ and it will count down until
the time has elapsed.
40 OPERATION
When the programmed sleep time has elapsed,
the unit will automatically turn off (to Standby
mode). Note that the front panel display will dim
to one half brightness when the Sleep function is
programmed. To cancel the Sleep function, press
and hold the Sleep Button
mation display returns to normal brightness and
the Sleep indicator numbers disappear and the
words

Source Selection

• To select a source, press any of the Source
Selector buttons on the remote
CD.
NOTE: After pressing one of the Input Selector
D to turn the unit on, press the
buttons
AVR Selector
control the AVR functions.
• The input source may also be changed by
pressing the front-panel Input Source Selector
button %. Each press of the button will move
the input selection through the list of available
inputs.
• As the input is changed, the AVR will automati-
cally switch to the digital input (if selected),
surround mode component video input, A/V Sync
and the
Delay and Night Mode configurations that were
in effect the last time that input was used.
• The front-panel Video 4 Inputs Ô, Optical
Digital 4 Input * or the Coaxial Digital 4
Input Ó may be used to connect a device such
as a video game or camcorder to your home
entertainment system on a temporary basis.
When they are configured as outputs (see page
25) you can also connect an audio or video
recorder (composite or S-Video) for recording the
source selected.
• As the input source is changed, the new input
name will appear momentarily as an on-screen
display in the lower third of the video display. The
input name will also appear in the Main
Information Display ˜.
• When a pure audio input (CD, Tuner, Tape,
6/8 Channel Input) is selected, the last video
input used remains routed to the Video Out-

• When a Video source is selected, its audio
signal will be fed to the speakers and the video
signal for that input will be routed to the

6-Channel/8-Channel Direct Input
• There are four input choices available for use
with sources such as a DVD-Audio or SACD
player that are connected to the 8-Channel

according to the way your system and source
equipment is configured:
• The 6 CH DIRECT input should be used when
the SBR and SBL inputs are NOT in use and the
input source device has its own internal bass
management system. This input passes the input
from the source directly through to the volume
control without any analog to digital conversion
and it mutes the unused input jacks to prevent
unwanted noise from interfering with system
performance.
• The 6 CH DVD AUDIO input should be used
when the SBR and SBL inputs are NOT in use and
the input source device does NOT have its own
internal bass management system. When this
input is in use the analog source is converted to
digital so that you may use the same Quadruple
Crossover bass management options for the
direct input as you do with all other inputs.
This input also mutes the unused input jacks to
prevent unwanted noise from interfering with
system performance.
