Output Level Adjustment; Using Ezset - Harman Kardon AVR 230 Owner's Manual

Delay times are only adjustable for the Dolby modes,
so you will notice that the DELAY menu may not
be accessed when any other mode, such as a DTS or
Logic 7 option, has been selected. In addition, when a
non-Dolby Digital mode such as Dolby 3 Stereo or
Pro Logic II is selected, adjustments may be made to
the Surround speakers only.
To set the delay time for a specific input, the
DELAY ADJUST menu (Figure 7) should be
visible on your on-screen display. If the system is not
already at that point, press the OSD Button v to
bring up the MASTER MENU, press the
Button n until the on-screen
cursor is pointing at
›
the DELAY ADJUST line. Press the Set
Button p to call up the menu.
NOTE: In order to adjust the Delay settings for the
surround back channels, a Dolby Digital or DTS source
must be playing. This enables the system to activate
the surround back processing mode.

Output Level Adjustment

Output level adjustment is a key part of the configura-
tion of any surround sound product. It is particularly
important for a digital receiver such as the AVR 230,
as correct outputs ensure that you hear soundtracks
with the proper directionality and intensity.
IMPORTANT NOTES:
• Listeners are often confused about the operation of
the surround channels. While some assume that
sound should always be coming from each speaker,
most of the time there will be little or no sound in
the surround channels. This is because they are
› cursor
only used when a movie director or sound mixer
specifically places sound there to create ambience
or a special effect, or to continue action from the
›
cursor front of the room to the rear. Once the output
levels are properly set, it is normal for surround
speakers to operate only occasionally. Artificially
increasing the volume to the rear speakers may
destroy the illusion of an enveloping sound field
that duplicates the way you hear sound in a movie
theater or concert hall.

• When the AVR 230 is configured for 6.1-channel
operation using a single surround back speaker, the
output level adjustments will still provide an adjustment
for separate surround back left and surround back right
positions even though your system has only one
surround back speaker. This means that the Surround
Back channel will seem to appear twice, and in 6.1
operation this is normal. The separate SBL/SBR adjust-
SYSTEM CONFIGURATION SYSTEM CONFIGURATION
ments for 6.1 operation are needed to optimize the
balance between the two discrete channels within the
AVR as they are mixed for output to a single speaker.
Before beginning the output level adjustment process,
make certain that all speaker connections have been
properly made. The system volume should be set to
the level that you will use during a typical listening
session. While the AVR 230 allows you to set output
levels manually, we recommend that the EzSet system
be used when the AVR is first installed, to establish the
initial level settings.

Using EzSet

Harman Kardon's exclusive EzSet remote makes it
possible to quickly and accurately set the AVR 230's
output levels without the use of a sound pressure

meter, although manual adjustment is also available.
However, for the easiest setup, follow these steps
while seated in the listening position that will be used

most often:
1. Make certain that all speaker positions have been
properly configured for their "large" or "small" set-
tings (as outlined above) and turn off the OSD
system if it is in use.
2. Adjust the volume so that it is at -15dB, as
shown in the on-screen display or Lower
Display Line ¯.
3. Hold the remote in front of you at arm's length,
being sure not to cover the EzSet Sensor
Microphone
4. Press and hold the SPL Selector Button
three seconds. Release it when the Program/
SPL Indicator c stops flashing and remains
lit. Within five seconds, press the 5 Button r
on the remote if your system is configured for
5.1 operation with standard speakers or the
7 Button r on the remote if your system is
configured for 6.1/7.1 operation with one or two
rear surround speakers. Once the correct channel
configuration button has been pressed, the test
noise will be heard from the front left speaker.
5. At this point, EzSet will take over, adjusting the
output level of each channel so that when the
process is complete all levels will be equal and at
the set reference point. This process may take a
few minutes, depending on the extent of adjust-
ment required.
