AVR745
OPERATION
long as the AVR 745 is turned on, unless the setting is
changed in the OSD menu system, as described
above. However, once the AVR 745 is turned off, the
setting is canceled. When the unit is turned on again,
the front-panel jacks will return to their normal default
setting as inputs. If you wish to use the jacks as out-
puts at a future time, the setting must be changed
again using the OSD menu system, as described
above.
Output Level Trim Adjustment
Normal output level adjustment for the AVR 745 is
established using EzSet/EQII, as outlined on pages
29–33. In some cases, however, it may be desirable
to trim 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 )∫˙.
Press the Devices Button 4 on the TC 30 remote
and then press the Screen Button 6 next to AV
Receiver. Next, press the Screen Button
6 next to Setup Menu and after the choic-
es in the LCD Screen 7 change, press the Screen
Button 6 next to Channel and FRONT
L LEVEL will appear in the Lower Display Line
$. To change the level, first press the OK/Enter
Button E or the Set Button œ, and then use
Navigation Buttons D© to raise or
the /
⁄ ¤
lower the level. DO NOT use the volume control, as
this will alter the reference setting.
Once the change has been made, press the OK/Enter
Button E or the Set Button œ and then press
Navigation Buttons D© to select
the /
⁄ ¤
the next output-channel location that you wish to
adjust. To adjust the subwoofer level, press the
Navigation Button o until WOOFER
/
⁄ ¤
LEVEL appears in the Lower Display Line $
or on-screen display.
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 5 seconds, the AVR 745 will return to
normal operation.
The output levels may also be adjusted using the on-
screen menu system to either the internal test tone or
an external test disc by following the instructions
shown on page 37

EzSet/EQII Operation
A major advantage of EzSet/EQII over competitive
systems is its ability to store up to three different EQ
Designs. This allows you to preset different combina-
tions of speakers or manually set adjustments, or per-
haps create different EQ Designs with the microphone
in different locations to optimize the system for either
your favorite listening position, or for a different setting
when more people are in the listening room. You may
also turn off the EzSet/EQII system entirely so that
you may compare the sound of your system with
the system in a particular EQ Design, or with it out of
the system.
To access the settings for selecting an EQ Design pre-
set, press the Devices Button 4 on the TC 30
followed by the Screen Button 6 at the top of
the row of buttons on the left side of the TC 30, to the
left of AV Receiver on the LCD screen. After
the list of options displayed in the LCD Screen 7
changes, press the Page Left/Right Button 8
to go to the second page of AV Receiver
settings. When that page of settings appears, you may
do the following:
• Press the Screen Button 6 to the left of EQ
On/Off to bring the EQ settings into the signal
path, or to put the system in the Bypass mode,
which removes the equalization filters.
• Press the Screen Button 6 to the left of EQ
Presets to cycle through the EQ Designs
stored in each of the three memory positions, as
shown in the instructions on page 38.
Subwoofer Control
If you have a 7.2 system with two subwoofers pres-
ent, you may occasionally wish to turn one of the sub-
woofers off to accommodate your preferences with a
particular movie or musical program, or to demon-
strate the change made by using one subwoofer or
two. To do this, press the Devices Button 4 on
the TC 30 followed by the Screen Button 6 at
the top of the row of buttons on the left side of the
TC 30, to the left of AV Receiver on the
LCD screen. After the list of options displayed on the
LCD Screen 7 changes, press the LCD Screen 7
to go to the second page of AV Receiver
settings. When that page of settings appears, press
the Screen Button 6 to the left of Sub 2
On/Off to turn the feed to the second sub-
woofer on or off.
Dim Function
Since the AVR 745 will often be used when movies
or other kinds of video programming are viewed under
low-light conditions, you may wish to lower the bright-
ness of the front-panel displays and indicators so that
they do not distract from the video presentation. You
29
harman/kardon
may dim the displays using the menu system, as
shown on page 49, or you may control the brightness
directly from the remote.
Press the Devices Button 4 on the TC 30 remote
and then press the Screen Button 6 next to AV
Receiver. Next, press the LCD Screen 7
and after the choices in the LCD Screen 7
change, press the Screen Button 6 next to
Dim. Note that when the displays are dimmed or
turned off, the blue lighting around the Standby/On
Switch 1 will continue to stay lit as a reminder that
the AVR is still turned on. The accent lighting for the
Volume Control ) will remain at its normal level,
rather than dim when the panel displays are at half-
brightness.
Note that all changes to the front-panel brightness
level are temporary; the displays will return to full-
brightness after the AVR is turned off and then on
again. To return the displays to full-brightness without
turning the unit off, return the TC 30 to the AVR
Device screen, and press the Screen Button 6
next to Dim as needed until the displays are on.
In addition to lowering the brightness of the displays
or turning them off completely, you may wish to have
them appear whenever a button on the remote or
front panel is pushed, and then gradually fade out after
a set time period. You may do this by making the
appropriate settings in the VFD FADE TIME
OUT line of the ADVANCED SELECT
menu, as shown on page 49.
Memory Backup
This product is equipped with a memory backup
system that preserves the system configuration infor-
mation and tuner presets if the unit is accidentally
unplugged or subjected to a power outage. This
memory will last for at least four weeks, after which
time all information must be reentered.
