various sources, as opposed to the test tone. See
page 31 for more information on trimming the
output levels to external source material.
NOTE: The subwoofer output level is not
adjustable using the test tone. To change the
subwoofer level, follow the steps for Output
Level Trim Adjustment on page 32.
When all channels have an equal volume level,
the adjustment is complete. Now 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. To exit this
menu, press the
⁄ / ¤ buttons D until the
on-screen › cursor is next to the BACK T O
MASTER MENU line, and then press the
Set Button F to return to the
MASTER
MENU .
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 Ò. 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 ⁄ / ¤ but-
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.
After one input has been adjusted for analog or
digital input, speaker type and surround mode,
return to the
INPUT SETUP line on the
MASTER menu and enter the settings for each
input that you will use. In most cases, only the
digital input and surround mode may be different
from one input to the next, while the speaker
type will usually be the same (inputs set to
GLOBAL ). But if prefered you can also select
different speaker types or turn speakers on or off
individually for each input in use.
Once the settings outlined on the previous pages
have been made, the AVR is ready for operation.
While there are some additional settings to be
made, these are best done after you have had an
opportunity to listen to a variety of sources and
different kinds of program material. These
advanced settings are described on pages 33 to
34 of this manual. In addition, any of the settings
made in the initial configuration of the unit may
be changed at any time. As you add new or
different sources or speakers, or if you wish to
change a setting to better reflect your listening
taste, simply follow the instructions for changing
the settings for that parameter as shown in this
section.
Note that any settings changed at any time, also
when the discrete buttons are used only, will be
stored in memory in the AVR, also if it´s turned
off completely, unless it will be reset (see page
42).
Having completed the setup and configuration
process for your AVR, you are about to
experience the finest in music and home-
theater listening. Enjoy!
