SYSTEM CONFIGURATION
Surround Speakers for 6.1 Systems
A 6.1 surround speaker adds an additional center
back surround speaker to the system, enabling you to
enjoy the benefits of advanced surround modes such
as Dolby Digital EX, DTS-ES and Harman Kardon’s
proprietar
y Logic 7/7.1 processing.
T
o step up to a 6.1 system,
first place the speakers
for a 5.1 system, as shown on page 14. The “sixth”
speaker should ideally be placed at the center of the
room’s rear wall, pointing directly towards the front
center channel speaker.
IMPOR
T
ANT NOTE
:
It is not possible to configure the
AVR 140 for 7.1-channel operation. Do not connect
more than one speaker to the
Surround Back
Speaker Outputs
¶, as doing so may damage your
speakers, the AVR 140 or both. When 7.1-channel
infor
mation is received, for example through the
6/8-Channel Direct Inputs g,
or when deriving
7-Channel Stereo or Logic 7/7.1 surround informa-
tion, the AVR 140 combines the left and right sur-
round back channel infor
mation and outputs it as a
single surround back channel.
Since subwoofers produce nondirectional sound,
they
may be placed almost anywhere in a room. Actual
placement should be based on room size and shape
and the type of subwoofer used. One method of find-
ing the optimal location for a subwoofer
is to begin by
placing it in the front of the room, about six inches
from a wall,
or near the front cor
ner of the room.
Another method is to temporarily place the subwoofer
at your nor
mal listening position, and then walk
around the room until you find a spot where the sub-
woofer
sounds best.
Place the subwoofer in that spot.
Y
ou should also follow the instructions of the
sub-
woofer’s manufacturer, or you may wish to experiment
with the best location for a subwoofer in your listening
room.
NOTES ON
SPEAKER PLACEMENT:
1.
The limitations of your listening room,
including the
placement of walls and furniture, may make it diffi-
cult to follow the speaker placement suggestions
shown above
.
Depending on the specific layout of
the room, here are some ways to compensate for
unusual conditions:
• Try to follow the suggested placement, but move
the speakers within a few feet from the preferred
locations.
•
Regardless of where they are placed,
always tr
y
to make certain that the main surround speakers
are the same distance from the front speakers.
(For example, try not to have the right surround
speaker further back into the room than the left
surround speaker.)
•
If it is not possible to wall-mount or place speak-
e
rs on a shelf, consider the use of optional floor
stands, available for many speakers.
2. When using ceiling mounted in-wall speakers, fol-
l
ow the same guidelines shown for conventional
floor or shelf-mounted speakers.
System Setup
Once the speakers have been placed in the room
a
nd connected, the remaining steps in the setup
process are to configure each source input to match
the physical connections you have made, select a sur-
round mode
, program the AVR 140’s bass manage-
ment system for the type of speakers used in your
system, calibrate the output levels, and set the delay
times used by the surround sound processor.
You are now ready to power up the AVR 140 to begin
these final adjustments.
1. Make certain that the
AC Power Cord ‹
is firmly inserted into an unswitched AC outlet.
To maintain the unit’s safety rating, DO NOT
replace the power cord with one that has a
lower current capacity.
2. Press the
Main Power Switch 1 in until it
latches and the word “OFF” on the top of the
switch disappears inside the front panel. Note
that the
Power Indicator 2 will turn amber,
indicating that the unit is in the Standby mode.
3. Remove the protective plastic film from the front-
panel lens
.
If left in place, the film will affect the
perfor
mance of your remote control
.
4. Install the three supplied AAA batteries in the
remote as shown. Be certain to follow the (+)
and (–) polarity indicators that are on the top of
the battery compartment.
5. Turn the AVR 140 on either by pressing the
Standby/On Switch 2 on the front panel,
or
via the remote by pressing the
Power On Button
d, the AVR Selector f or any of the Input
Selectors
degde on the remote.
When the unit is tur
ned on, the entire list of
options will briefly light for both the
Input
Indicators
Ú and the Surround Mode
