Manual Output Level Adjustment - Harman Kardon AVR 235 Owner's Manual

System Configuration

Manual Output Level Adjustment

Output levels may also be adjusted manually,
either to set them to a specific level with an SPL
meter, or to make fine tuning adjustments to the
levels obtained using the EzSet remote.
Manual output level adjustment is most easily
done through the
CHANNEL ADJUST
menu (Figure 9). If you are already at the main
Button D until the on-
menu, press the

screen © cursor is next to the
CHANNEL
line. If you are not at the main menu,

When the
CHANNEL ADJUST
appears, the test tone is off. Use the
Navigation Button D to select any channel
for adjustment using an external source, such as
a test disc, from which to judge the output levels.
After the © cursor is pointing to the channel to
be adjusted, press the / Navigation Button

Ea to raise or lower the output level.
However, before proceeding with any manual
adjustment we recommend that you first use the
AVR's internal test tone generator and automatic
sequencer to send a tone to each channel so that
you may verify that all speaker connections have
been properly made.
To turn the test tone on and have it automatical-
ly circulate among the channels where a speaker
has previously been configured (see page 24),

Button Ea once to immediately start the
test tone at the Front Left speaker. It will circulate
clockwise around the room, playing for two sec-
onds in each speaker before switching to the
next speaker position. The © cursor will blink
next to the active speaker to indicate which
speaker the sound should be coming from.
IMPORTANT NOTE: Because this test noise will
have a much lower level than normal music, the
volume must be lowered after the adjustment for

all channels is made, but BEFORE you return to
the main menu and the test tone turns off.
NOTE: Remember to verify that the speakers have
been properly connected. As the test noise circu-
lates, listen to make certain that the sound comes
from the speaker position shown in the Main
Information Display ˜. If the sound comes
from a speaker location that does NOT match the
position indicated in the display, turn the AVR off
using the Main Power Switch 1 and check the
speaker wiring or connections to external power
amplifiers to make certain that each speaker is
connected to the correct output terminal.
After checking for speaker placement, let the test
noise circulate again, and listen to see which
channels sound louder than the others. Using the
menu (Figure

Buttons Ea on the remote to bring all
speakers to the same volume level. When one of

If you are using a sound-pressure level (SPL)
meter for precise level adjustment with the test
tone, open the main Volume Control d to -
15dB and set the individual output level for each
channel so that the meter reads 75dB, C-
Weighted Slow. After all settings are made turn
the main volume down.
You may also make these same adjustments with

The output levels may also be adjusted at any
time using the remote control and semi-OSD sys-
tem. To adjust the output levels in this fashion,
press the Test Button 8. As soon as the
button is pressed, the test tone will begin to
circulate as indicated earlier. The correct channel
from which the test noise should be heard will be
shown in the lower third of the video screen and
in the Main Information Display ˜. While
the test noise is circulating, the proper channel
position will also be indicated in the Speaker/
Channel Input Indicators $ by a blinking
letter within the correct channel. Turn up the
Volume d until you can hear the test noise
clearly.
To adjust the output level, press the
tons D until the desired level is shown in the
display or on screen. Once the buttons are
released, the test noise will begin to circulate
again in five seconds.
When all channels have the same output level,
turn the Volume d down to about –40dB,
otherwise the listening level may be too high as
soon as the source's music starts to play.
Afterwards press the Test Tone Selector 8
button again to turn the test tone off and
complete the process.
IMPORTANT NOTE: The Output level adjust-
ment made will be effective for all inputs, but
only for the actual surround mode selected. To be
effective for any other mode select that mode
(with any input) and repeat the level adjustment
described above. This will also allow you to com-
pensate level differences between speakers, that
may be different with each surround mode, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected.
Note: Output level adjustment is not available
for the VMAx or Surround Off mode, as no
surround speakers are used (so level differences
between the speakers in the room cannot occur).
But to compensate level differences between
stereo, VMAx and other surround modes (inde-
pendently from the input selected) the outputs
can be adjusted with the Level Trim Adjustment
procedure, see page 32, also for the Surround Off
(Stereo) and VMAx modes.
