LFE Low-Pass Filter Setting

The LFE LP FLT line selects the frequency set-

ting below which sounds that may be available from a

pecial low-frequency effects (LFE) track are sent to

he subwoofer. In most cases, this setting will be set

accurately by EzSet/EQII but, should you wish to make

a change from that setting or the 120Hz frequency

that is most commonly used in the creation of LFE

hannels by motion picture sound mixers, after making

sure that the

SPEAKER SIZE menu (Figure

27) is on the screen, press the

⁄/¤ Navigation

Buttons

so that the cursor is pointing to

FE LP FLT

Press the

‹/› N

avigation

Buttons

to begin the selection process, and

note that the warning

message (Figure 28) will appear,

reminding you to rerun EzSet/EQII after all changes

have been made.

When the

SPEAKER SIZE menu returns to

the screen, press the

‹/› Navigation Buttons

to make your selection. When the desired

setting appears, press the

⁄/¤ Navigation

Buttons

to move the cursor to any other

line on this menu where you wish to make a setting

change, or go to the

BACK TO MANUAL

SETUP

menu and then press the OK/Enter

Button

E in the TC 30 or the Set Button

to continue with overall configuration.

Sub Mode Setting

When the Front Left/Right speakers are configured as

“Large” and a subwoofer is detected by EzSet/EQII

or manually configured as being available, additional

options are available to further customize bass redirec-

tion. To change these settings, first make sure that

the

SPEAKER SIZE menu (Figure 27) is on

the screen, and then press the

⁄/¤ Navigation

Buttons

so that the cursor is pointing to

SUB MODE. Press the ‹/› Navigation Buttons

to begin the selection process, and note that

the warning message (Figure 28) will appear, remind-

ing you to rerun EzSet/EQII after all changes have

been made.

The following options are available:

• The default setting for Large front left/right speakers

when a subwoofer is present is SUB L/R+LFE.

In this mode, all sounds below the crossover point

set on the

LFE LP FLT line will be sent to

BOTH the subwoofer

and front left/right speakers.

• To send only the LFE channel information to the

subwoofer, but have all other (“derived”) low-

frequency sounds sent to the front left/right

speakers, select the

SUB (LFE) setting.

• To have low-frequency information sent to the sub-

woofer only when Large speakers are selected,

choose

SUB

(L/R)

This option is only avail-

able when the unit is set to

SURROUND OFF

so that a pure analog audio path is provided.

• When no subwoofer is present and Large speakers

are configured for the front left/right position, select

NONE. This will route all low-frequency informa-

ion to the front left/right speakers.

When the

SPEAKER SIZE menu returns to

the screen, replacing the warning message, press the

‹/› Navigation Buttons D

to make your

election. When the desired setting appears, press the

⁄/¤ Navigation Buttons D

to move the

cursor to any other line on this menu where you wish

to make a setting change, or go to the

BACK TO

MANUAL SETUP

menu and then press the

OK/Enter Button E in the TC 30 or the Set

Button

to continue with overall configuration.

Subwoofer Configuration

The AVR 745 is among the very few A/V receivers or

surround processors that are capable of feeding two

subwoofers, as well as the standard configuration of a

single subwoofer. Although one subwoofer is capable

of delivering powerful bass, the use of two subwoofers

in conjunction with EzSet/EQII expands the bass

response over a wider listening area.

The default setting for the AVR 745 is a single sub-

woofer, but if you are using two subwoofers, it is

important to change the setting on the NO. SUBS

line. To do that, press the ‹/› Navigation Buttons

as needed so that the cursor is pointing to

NO. SUBS, and then press the ‹/› Navigation

Buttons

so that the number shown changes

from

1 to 2.

Subwoofer Size

The final setting on the SPEAKER SIZE menu

enables you to change the setting for the subwoofer

size. In the event that EzSet/EQII did not accurately

enter the correct size, or if you wish to experiment

with a different setting, first make sure that the

SPEAKER SIZE menu (Figure 27) is on

the screen; then press the

⁄/¤ Navigation

Buttons

so that the cursor is pointing to

SUB SIZE and then press the ‹/› Na

viga

tion

Buttons

to begin the selection process.

Note that a warning message will appear for four

seconds to remind you to rerun EzSet/EQII after

all changes have been made

Select a setting that best matches the diameter of

your subwoofer’s driver, or which provides the appro-

priate high-pass filter setting for your system. In each

case,

the frequency of the high-pass filter deter

mines

the frequencies below which no information is sent to

the subwoofer

• The setting for an 8-inch/200mm driver activates a

38Hz subwoofer high-pass filter.

•

The setting for a 10-inch/250mm driver activates a

30Hz subwoofer high-pass filter.

• The setting for a 12-inch/305mm driver activates a

20Hz subwoofer high-pass filter.

• The setting for a 15-inch/380mm driver activates a

15Hz subwoofer high-pass filter.

When all changes to speaker-related settings have

been made, press the

⁄

Navigation Buttons

ntil the cursor is on the

ACK TO

MANUAL SETUP

menu; then press the

OK/Enter Button E on the TC 30 or the Set

Button

so that you may make any other adjust-

ments to the system parameters. Remember to rerun

he EzSet/EQII system if any changes have been

made to the settings in this menu,

ollowing the

instructions for using the Manual mode shown on

page 30.

The speaker configuration settings may also be adjusted

directly and without going into the OSD menu system

at any time using the TC 30 remote control. To adjust

the speaker settings, first press the Devices Button

4 on the TC 30, and then press the Screen

Button

6 at the top of the left vertical row, to the

right of the

AVR image on the remote’s screen.

When the images in the LCD change, press the

Screen Button 6 next to the box with the word

SPEAKER. Immediately press the ‹/›

Navigation Buttons D

until the desired

speaker position’s name appears in the

Lower

Display Line

D, and in the semi-OSD message,

if the video in use is a 480i source.

Within five seconds of stopping at the desired speaker

position, press the

OK/Enter Button E. Use the

‹/› Navigation Buttons D

to select the

desired setting and then press the

OK/Enter Button

E again to enter the setting into the system memory.

Delay Settings

Due to the different distances between the listening

position and each speaker position, the amount of

time it takes for sound to reach your ears from each

channel is different. You may compensate for this dif-

ference through the use of the

delay settings

to adjust

the timing for the speaker placement and acoustic

conditions in your listening room or home theater.

In most cases, the settings established by EzSet/EQII

are accurate to within one foot, but the placement of

the microphone and other factors may influence

the setting. Should you wish to manually adjust the

channel delay times, follow the instructions shown

below. Whenever adjustments to the delay settings are

made remember that the distance settings need not

be accurate to the inch,

as the system is designed to

accommodate a typical listening area rather than the

precise measurement from the speakers to a specific

“sweet spot”

position.
