Output Level Adjustment - Harman Kardon AVR 140 Owner's Manual

Delay times are adjustable for all surround modes.
Although all channels will appear on screen with the
default or previously entered distances, the menu sys-
tem will only allow you to adjust the settings for those
channels which are actually used by the current sur-
round mode. For example, when you are listening to
music CDs using the CD input in DSP Surround Off
mode, you may adjust the delay settings for the front
left, front right and subwoofer channels only. The cur-
sor will simply skip the other channels as you navigate
through the menu. Therefore, the first time you adjust
the delay settings, it is recommended that you select a
5.1-, 6.1- or 7.1-channel surround mode, depending
on the number of speakers in your system. For the
purposes of setting the delay distances, the Logic 7
modes allow access to the settings for all channels
without requiring that you play a source.
When your system includes a surround back speaker,
delay distances should be entered twice for this
speaker, once for the surround back left channel,
and again for the surround back right channel. This
enables the mixing circuit that combines the signals
for these channels when a 7.1-channel surround
mode is in use to output the information correctly.
To set the delay time for a specific input, the
DELAY ADJUST submenu (Figure 10) should
be visible on your on-screen display. If it is not, press
the OSD Button v to bring up the MASTER
Button n until the
MENU, and press the

SETUP line. Press the Set Button p to enter
the MANUAL SETUP submenu, and then scroll

the Set Button p again, and the DELAY
ADJUST submenu will appear (see Figure 10).

Once the DELAY ADJUST menu is on your

feet. If your measurements are in feet, proceed to the

this fashion to enter the distance from the listening

round back left (SBL), surround left (SL) and
subwoofer (SUB) speakers. Remember that the

Output Level Adjustment

31
Output level adjustment is a key part of the configura-
30
tion of any surround sound product. It is particularly
29
important for a digital receiver such as the AVR 140,
28
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
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
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
cursor
›
destroy the illusion of an enveloping sound field
that duplicates the way you hear sound in a movie
theater or concert hall.

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 sur-
round 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-
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 sure 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.
Using the Full-OSD System
Follow these steps while seated in the listening posi-
tion that will be used most often:
1. Adjust the volume so that it is at -15dB, as
shown in the on-screen display or Lower
Display Line ı.
2. Make certain that all speaker positions have been
properly configured for their LARGE or
SMALL settings (as outlined above).
3. Output level adjustment is most easily done
through the CHANNEL ADJUST sub-
menu (Figure 11). If you are already at the
MASTER MENU, press the
until the on-screen cursor is next to the
›
MANUAL SETUP line. Press the Set
51
Button p to enter the MANUAL SETUP

submenu, and then scroll down using the
Button n until the › cursor is pointing
49 ¤
to the CHANNEL ADJUST line.

Press the Set Button p again, and the
CHANNEL ADJUST submenu will
appear (see Figure 11).
