OPERATION

Table on pages 37–38 for a listing of the remote
control buttons that have been programmed to
control the iPod. In brief, the

Reverse Search,

Play and Forward Search Buttons

and the

⁄

‹

›

Buttons

and

Set Button

may be used in a similar manner to the corresponding
controls on the iPod. Additional buttons on the remote
may also be used to navigate your iPod’s albums
and playlists. Complete details on operating an iPod
using

and an AVR remote are furnished

with .

The front-panel controls may be used to access a lim-
ited number of iPod functions. Press the

Tuner Mode

Button

to play or pause the current track. The

Tuning Selector

may be used to search reverse

(left side of button) or forward (right side of button)
through the tracks. Press the

Tuner Band Selector

to call up the iPod’s menu. Press the

to scroll, and the

Set Button

select.

Output Level Trim Adjustment

Normal output level adjustment for the AVR 140 is
established using the test tone, as outlined on pages
23–24. In some cases, however, it may be desirable
to adjust the output levels using program material such
as a test disc, or a selection you are familiar with.
Additionally, the output level for the subwoofer can
only be adjusted using this procedure.

To adjust the output levels using program material, first
set the reference volume for the front left and front right
channels using the

Volume Control

If you are using a disc with test signals or an external
signal generator as the source from which to trim the
output levels, you may use a handheld SPL meter to
guide you to the correct SPL levels. Set the meter to
the C-Weighting Slow scale, and adjust the volume
until the meter reads 75dB.

Once the reference level has been set, press the

Channel Select Button

and

FRONT L

LEVEL

will appear in the

Lower Display Line

and semi-OSD. To change the level, first press

the

Set Button

, and then use the

⁄

Buttons

to raise or lower the level. DO NOT

use the volume control, as this will alter the
reference setting.

Once the change has been made, press the

Set

Button

and then press the

⁄

Buttons

to select the next output channel location you wish to
adjust. To adjust the subwoofer level, press the

⁄

Buttons

until

WOOFER LEVEL

appears in

the

Lower Display Line

and on screen.

Repeat the procedure as needed until all channels
requiring adjustment have been set. When all adjust-

ments have been made and no further adjustments
are made for five seconds, the AVR 140 will return to
normal operation.

The channel output for any input may also be adjusted
using the full-OSD on-screen menu system. First, set
the volume to a comfortable listening level using the

Volume Control

. Then, press the

OSD

Button

to bring up the

MASTER MENU

(Figure 1). Press the

Button

until the on-

screen

›

cursor is next to the

MANUAL

SETUP

line. Press the

Set Button

to display

the

MANUAL SETUP

submenu, and use the

⁄

Buttons

to scroll to the

CHANNEL

ADJUST

line. Press the

Set Button

again to

display the

CHANNEL ADJUST

submenu.

Once the menu appears on your video screen, first
use the

⁄

Buttons

to move the on-screen

›

cursor so that it is next to the

TEST TONE

line. Press the

‹

›

Buttons

so that

OFF

appears. This will turn off the test tone and allow you
to use your external test disc or other source material
as the reference. Then, use the

⁄

Buttons

until the

›

cursor is next to the

TEST TONE

SEQ

line so that you may select between automatic

and manual movement of the test tone from one
channel to the next. When

AUTO

appears, the test

tone will automatically circulate from one channel to
the next, pausing momentarily at each channel. If you
adjust the level of any channel, the test tone will
remain paused at that channel until several seconds
after your last adjustment before continuing to the next
channel. When

MANUAL

appears, the test tone will

remain paused at the last channel until you use the

⁄

Buttons

to select another channel.

At each channel position, use the

‹

›

Buttons

to change the output level. Remember, the goal is to
have the output level at each channel be equal when
heard at the listening position. Regardless of the
method used to adjust the output levels, whether the
test tone or an external source is used, remember that
when the AVR is configured for 6.1 operation with only
a single surround back speaker, you will still have an
output adjustment for both a surround back left and
surround back right speaker location even though
there is only one speaker. This is not a duplicate
adjustment. Rather, it is needed so that the proper bal-
ance is achieved for 7.1-channel processing modes
when the discrete surround back channels are mixed
to a single output.

If you wish to reset all the levels to their original
factory default of 0dB offset, press the

⁄

Buttons

so that the on-screen cursor is next to the

CHANNEL RESET

line and press the

‹

›

Buttons

so that the word

appears. After the

levels are reset, resume the procedure outlined above

to reset the levels to the desired settings. When all
adjustments are done, press the

⁄

Buttons

to move the on-screen

›

cursor so that it is next to

BACK TO MANUAL SETUP

and then press

the

Set Button

if you wish to go back to the

manual setup menu to make other adjustments. If you
have no other adjustments to make, press the

OSD

Button

to exit the menu system.

NOTE:

The output levels may be separately trimmed for

each digital and analog surround mode. If you wish to
have different trim levels for a specific mode, select that
mode and then follow the instructions in the steps shown
earlier.

Memory Backup

This product is equipped with a memory backup sys-
tem that preserves the system configuration information
and tuner presets if the unit is accidentally unplugged
or subjected to a power outage. This memory will last
for approximately four weeks, after which time all infor-
mation must be reentered.
