BATTERY-FREE MEMORY BACKUP  
Memory Preservation  
This unit does not require memory preservation batteries. A  
built-in memory power back-up system preserves the contents  
of the memory during power failures and even when the unit is  
unplugged. The unit must be plugged in order to charge the  
back-up system.  
The memory preservation period after the unit has been  
unplugged varies depending on climate and placement of the  
unit. On the average, memory contents are protected over a  
period of a few weeks after the last time the unit has been  
unplugged. This period is shorter when the unit is exposed to a  
highly humid climate.

Notes:  
When using a playback-only VCR, you need to make only the output connections.  
This receiver can be used with only a monitor TV equipped with a video input jack.  
Interference may be caused between the TV and this receiver. If this interference occurs, place the receiver and the TV as far apart  
as possible. We do not recommend the use of a common TV/FM antenna (see antenna section).  
A DVD or other component equipped with a digital output can be connected to this receiver. The digital connection must be used in  
conjunction with an analog connection, because if the analog cable is disconnected, the audio output from TAPE OUT and VIDEO-2  
will not work.  
Remove the protective cap attached to the DIGITAL-1 (OPTICAL) jack before making the connection. When this jack is not used,  
replace the protective cap.

Positioning speakers  
Positioning speakers  
Speaker placement plays an important role in the reproduction of  
Surround sound. The placement of the speakers varies depending  
on the size of the room and the wall coverings used in the room.  
The illustration shows an example of a layout for standard speaker  
placement. Refer to this example when you position the speakers in  
order to experience the best of Surround sound.

Center

For ideal Surround effects, all speakers should be installed. If a  
center speaker or subwoofer is not connected, the sound from the  
unused channel is properly distributed to the connected speakers in  
order to produce the best Surround sound possible.  
Front: The left, right, and center speakers should face the seated  
listener and be placed at ear level. The center speaker produces a  
richer sound image by enhancing the perception of the sound’s  
source and movement.  
Surround

Right

Left  
Surround: Place the left and right Surround speakers 1 meter  
(3 feet) above the listener’s ear level and facing toward the sides of  
the room, making sure that the listener is within the speakers’ dis-  
persion angle. These speakers produce the feel of a moving sound  
while creating the sensation of being in the middle of the action.  
Subwoofer: Install a subwoofer with a built-in power amplifier for  
powerful bass sounds. The placement of the subwoofer does not  
affect the final quality of the sound image too much, so you can  
install it with the room layout in mind.

Refer to the speaker’s instruction manual for more details.

This receiver has five Surround modes. Select a suitable mode according to the type of music you are listening to, the media used, and your  
personal preference. The selected surround mode is automatically stored along with the selected source. Next time you select the same  
source again, the stored surround mode will be automatically recalled.  
Surround Modes  
Before using a Surround mode, make sure the Speaker Setup  
parameters have been set (refer to page 14). Once the parameters  
have been set, it is not necessary to set them again.  
Dolby Pro Logic Surround provides four channels of surround  
sound (Left/Right front, Center, and monaural Surround channels),  
with importance placed on the Center speaker.

Dolby Digital is a new-generation digital audio format for multi-  
channel surround audio.  
LIVE  
This mode reproduces the acoustics of a live performance.  
Adding to the conventional five full range channels, Dolby Digital  
supports one LFE (Low Frequency Effects) channel, which is used  
solely for correcting the bass range by using an independent sub-  
woofer. Dolby Digital is sometimes referred to as 5.1-channel for-  
mat since this LFE channel is calculated as 0.1.  
ARENA Surround  
This mode recreates the atmosphere of a concert in a domed sta-  
dium.  
STEREO  
Select this mode when you do not wish to use the surround mode.  
All input sound is output from the front speakers.  
DOLBY PRO LOGIC  
In Dolby Surround mode, video tapes and laser discs bearing the  
DOLBY SURROUND  
trademark are decoded to reproduce the multi-channel  
Surround sound of a movie theater.
