nal 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.
4. To turn the test tone on and have it automatically
circulate among the channels where a speaker
has been configured (see page 20), press the
Button n until the › cursor is pointing
¤
to the TEST TONE SEQ line on the
menu. Next, press the ‹/› Buttons o until
AUTO is shown. At this time the test tone will
immediately begin to circulate clockwise around
the room, playing for two seconds 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.
As the test noise circulates, listen to make certain that
the sound comes from the speaker position shown in
, next to the › cursor
the Lower Display Line
in the on-screen display, and by the flashing indication
in the Speaker/Channel Input Indicators
sound from a speaker location does NOT match the
position indicated in the display, turn the AVR 140 off
using the Main Power Switch and check the
speaker wiring or connections to external power
amplifiers to make certain that each speaker is
connected to the correct output terminal.
NOTE: Remember that when your system has only a
single Surround Back speaker and is thus configured
for 6.1-channel operation, you will hear the test tone
twice from the back speaker, once with the SBL indi-
cation and once with the SBR indication. This is nor-
mal, and it allows you to adjust the output balance for
the mixing circuit that creates a 6.1 output when 7.1
modes such as Logic 7/7.1 are used.
5. After checking for speaker placement, let the test
noise circulate again, and listen to see which
channels sound louder than the others. Using
the front left speaker as a reference, press the
Buttons o on the remote to bring all
/
‹ ›
of the speakers to the same volume level. When
Buttons o is pushed, the test
one of the /
‹ ›
noise circulation will pause on the channel being
adjusted to give you time to make the adjustment.
When you release the button, the circulation will
resume after five seconds.
6. Continue to adjust the individual channels until the
volume level sounds the same from each speaker.
Adjustments should be made with the
Buttons o on the remote only, NOT the main
volume controls. If you are using a sound-pres-
sure level (SPL) meter for precise level adjust-
ment, set the volume so that the meter reads
75dB on the C-Weighting, Slow scale.

You may also make these same adjustments with
complete manual control over the channel being
adjusted by pressing the
cursor is pointing to the TEST TONE SEQ line
on the menu and then using the ‹/› Buttons o
to select MANUAL. In the MANUAL mode, the
test tone will also start immediately, but the tone will
only be moved to another channel by pressing the
Button n. When the manual sequencing mode is
active, the tone is turned off by pressing the
Button n until the › cursor is pointing to the
TEST TONE line and the ‹/› Buttons o
are then pressed to select OFF.
If you find that the output levels are either uncomfort-
ably low or high, you may repeat the procedure.
Return to Step 2 and adjust the master volume either
slightly higher or lower to accommodate your particu-
lar room layout and your tastes. You may repeat this
procedure as many times as necessary to achieve
a desired result. In order to prevent possible damage
to your hearing or your equipment, we emphasize
that you should avoid setting the master volume
. If the
above 0dB.
When all channels have an equal volume level, the
adjustment is complete. Use the
to move the › cursor next to the TEST TONE
‹
line, and press the
OFF appears to stop the test tone.
Note that any time a given surround mode is selected,
even for a different source input, these output level
settings will be used. However, the output levels must
be set independently for each surround mode, includ-
ing variations such as Dolby Pro Logic II-Movie versus
Dolby Pro Logic II-Music. Although this may seem to
be tedious, it is necessary in order to optimize the
AVR's performance when differing methods are
employed to steer the audio materials to the various
channels. However, the AVR will carry over the settings
for one mode to the same mode in a different channel
configuration, such as Dolby Pro Logic IIx-Movie and
Dolby Pro Logic II-Movie. If you wish, as a shortcut to
get started quickly, you may set the levels for Dolby
Pro Logic IIx-Movie and copy down those settings, re-
entering them for each of the Dolby modes and enter-
ing the settings only for those speakers which are
available for each mode. Later, it is recommended that
you adjust the output levels while listening to various
sources, as opposed to the test tone. See page 34
for more information on trimming the output levels
to external source material.

NOTE: The subwoofer level is not adjustable when the
normal test tone is in use. The subwoofer output level
may be adjusted when the channel levels are being
trimmed to an external program source rather than the
test tone, as shown on page 34.
Using the Semi-OSD System
The output levels may also be adjusted at any time
using the remote control and semi-OSD system. To
adjust the output levels in this fashion, press the Test
Button i. 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 Lower Display Line
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.
To adjust the output level, press the
⁄
n 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, press
the Test Button i again to complete the process.
If you find that the output levels are either uncomfort-
ably low or high, you may repeat the procedure, but
first adjust the master volume either slightly higher or
lower (but not higher than 0dB) to compensate. Do
not adjust the volume during the procedure, as that will
cause the output levels to be higher or lower for only
some channels, resulting in uneven balance.
NOTE: Output level adjustment is not available for the
VMAx or Surround Off modes.
Additional Input Adjustments
After one input has been adjusted for Surround mode,
digital input (if any) and speaker type, go back to the
INPUT SETUP line on the MASTER
MENU (Figure 1) and enter the settings for each
input that you will use. In most cases, only the digital
input and surround mode will be different from one
input to the next, while the speaker type, crossover
frequency, Night mode and output level settings will
usually be the same and will automatically be carried
over when the previously configured surround modes
are selected. However, you will need to reenter
the delay and output level settings for each
surround mode.
When all settings and adjustments have been made,
press the OSD Button v to return to normal oper-
ation of the AVR.
