SYSTEM SETUP
While DVD-Audio also is output only in analog
form, many discs also contain PCM, Dolby Digital
or DTS digital tracks and may be played through
the
Digital Audio Outputs
01
.
Bass Management:
This setting activates the
SPEAKER
menu’s bass management settings,
to optimize playback of DVD-Audio discs through
the
Analog Audio Outputs
9B
. Three
settings are available:
•
Bypass
: This is the default setting. If your
receiver or processor is equipped with 6-chan-
nel inputs and is capable of adjusting the bass
management settings (speaker size, output
levels and delay times) for its 6-channel analog
inputs, then Harman Kardon recommends that
you leave this setting to
Bypass
, and adjust
the bass management settings on your receiver.
•
On
: If your receiver or processor is equipped
with “direct” 6-channel inputs and the receiver
is not capable of performing bass management
on these inputs, then change this setting on the
DMC 250 at the default of
ON
, and proceed to
the
AUDIO ADJUSTMENTS
menu to
program the bass management settings.
•
STEREO:
If your system consists of just a
pair of stereo loudspeakers, or a stereo system
with a subwoofer and a pair of satellite
loudspeakers, then change this setting to
STEREO
.
Speaker Settings
This menu allows you to adjust bass manage-
ment settings that control the audio output of
the
6-Channel Audio Outputs
B
for speaker
size, output level and delay times. The proper
adjustment of these settings is key to optimal
reproduction of DVD-Audio discs, when the
DMC 250 is used with a receiver or processor
that does not have audio adjustment capabilities
for the direct inputs.
Important Note:
In order to avoid audio
problems, when the DMC 250 is connected to a
receiver or processor that does have the
capability to adjust bass management parameters
for its multichannel inputs, you have the option
to either use that capability or adjust the settings
in the DMC 250. The preferred method of opera-
tion is to use the receiver for these adjustments.
In that case, remember to set the
Bass
Management
setting in the
AUDIO
SETUP
menu to
Bypass
. If you make the
adjustments using the DMC 250's settings, it is
important that the receiver's settings for the
multichannel direct inputs be disabled, or set to
“Large” for the speaker sizes and “0” for the
level adjustments and delay times, unless these
settings are also used for the receiver’s other
source inputs, in which case they should be left
the way you set them when you configured your
receiver. If you have any questions about the
capabilities of your receiver or processor, we
recommend that you consult its owner’s manual
or the manufacturer’s Web site for further
information.
If your receiver or processor does not have
6-channel analog inputs, make sure to select
Stereo
for the
Bass Management
setting in the
AUDIO SETUP
menu. Then
connect the
Analog Audio Outputs
9
to any
2-channel analog inputs on your receiver.
Before proceeding with the DMC 250’s audio
setup adjustments, we recommend that you first
use the menu system in your receiver or processor
to ascertain the settings already established for
“Speaker Size,” “Output Level” and “Delay
Time,” which may be set as a distance. Write
these settings down to refer to during the
configuration process.
Press the
Setup Button
8
to activate the
Setup menu; then use the
KL
Navigation
Buttons
9
until the
SPEAKER
submenu is
highlighted within a blue outline box, and press
the
Enter Button
6
.
Figure 4
The following adjustments are available on the
SPEAKER
menu for each speaker position. It is
recommended that you cycle through the adjust-
ments for each speaker position using the
KLM N
Navigation Buttons
9
to enter
the settings that are appropriate for your system.
Pressing the
Enter Button
6
displays a drop-
down menu with the selections available for that
setting. Use the
KL
Navigation Buttons
9
to highlight the appropriate setting, and
then press the
Enter Button
6
to select it.
You will notice that the adjustments for speaker
size and distance (used to calculate delay times)
are set in tandem for the front left and right
speaker pair, and for the surround left and right
speaker pair. Changing the settings for either
speaker in these pairs also affects that setting for
the other speaker in that pair. For this reason, it is
important to select the same brand and model for
both speakers in each pair, and also to place
them at about the same distance from the
listening position.
Speaker Size
Figure 4a
Speaker size is part of the bass management
system which determines which frequencies are
sent to the specific speaker position, and which
are sent to the subwoofer. The designation of
“size” does not refer to the speaker’s physical
size, but rather to the lowest frequency a speaker
can handle. For this purpose, “full-range”
speakers are considered “large,” while those not
capable of reproduction below 100Hz are
considered “small.” In general, if you are using a
packaged speaker system with smaller satellite-
type speakers and a subwoofer, you should select
Small
for all five speakers.
Large
should
only be selected if you are certain that your
speakers are capable of handling extreme low-
frequency sounds.
At the subwoofer setting, you can select whether
or not a subwoofer is present in your loudspeaker
setup.
Distance
Figure 4b
Due the different distances between the listening
position for the front channel speakers and the
surround speakers, the amount of time it takes
for sound to reach your ears from the front or
surround speakers is different. You may
compensate for this difference through the use of
the delay settings to adjust the timing for the
specific speaker placement and acoustic con -
ditions in your listening room or home theater.
Measure the distance from the listening position
to each of the individual loudspeakers. Once
done, select per loudspeaker the distance that is
closest to the one measured.
Before making any changes to the distance
settings, first move the blue bar down to the
UNIT
-line, press
Enter
6
and select the unit
for distances you prefer to enter, feet or meter
with the use of the
KL
Buttons
9
.
