34 SYSTEM CONFIGURATION

System Configuration

Sub Mode Setting

When the Front Left/Right speakers are con-

figured as “Large” and a subwoofer is detected

by EzSet/EQ or manually configured as being

available, additional options are available to

further customize bass redirection. To change

these settings, first make sure that the

SPEAKER SIZE menu (Figure 19) is on the

screen, and then press the

⁄

Navigation

Button

so that the cursor is pointing to

SUB MODE. Press the

‹

›

Navigation

Button

to begin the selection process, and

note that the warning message (Figure 20) will

appear reminding you to rerun EzSet/EQ 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

the 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

subwoofer only when Large speakers are

selected, choose

SUB (L/R).This option is

only available 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 information to the front left/right

speakers.

When the SPEAKER SIZE menu returns to

the screen, replacing the warning message, press

the

‹

›

Navigation Button

to make your

selection. When the desired setting appears,

press the

⁄

Navigation Button

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 Set Button

to continue

with overall configuration.

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/EQ 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 19) is on the screen; then press the

⁄

Navigation Button

so that the cursor is

pointing to

SUB SIZEand then press the

‹

›

Navigation Button

to begin the selection

process. Note that a warning message will

appear for 4 seconds to remind you to rerun

EzSet/EQ after all changes have been made.

Select a setting that best matches the diameter

of your subwoofer’s driver, or which provides the

appropriate high-pass filter setting for your sys-

tem. In each case, the frequency of the high-pass

filter determines 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

Button

until the cursor is on the BACK

TO MANUALSETUP

menu and then

pressing the Set Button

so that you may

make any other adjustments to the system

parameters. It is also important to remember to

rerun the EzSet/EQ system if any changes have

been made to the settings on this menu,

following the instructions shown on page 33 for

using the Manual mode.

The Speaker Configuration may also be changed

at any time without using the full-OSD on-screen

menu system by pressing the Speaker Selector

on the front panel or

on the remote

control. Once the button is pressed,

FRONT

SPEAKER

will appear in both the lower third

of the video display and the Main Information

Display

Within five seconds, either press the

‹

›

buttons

on the front panel or the

⁄

buttons

on the remote to select a different speaker

position, or press the Set Button

begin the adjustment process for the front left

and right speakers.

When the Set button

has been pressed

and the system is ready for a change to the front

speaker setting, the on-screen display and Main

Information Display

will read FRONT

LARGE

or FRONT SMALL depending on

the current setting. Press the

‹

›

buttons

on the front panel or the

⁄

buttons

the remote until the desired setting is shown,

using the instructions for “large” or “small”

shown earlier, then press the Set button

If another speaker position needs to be changed,

press the

‹

›

buttons

on the front panel

or the

⁄

buttons

on the remote to

select a different speaker position, press the Set

button

and then the

‹

›

buttons

on the front panel or the

⁄

buttons

the remote until the correct speaker setting is

shown and press the Set button

again

to confirm the selection.

To assist in making these settings, the icons in

the Speaker/Channel Input Indicators

will change as the speaker type is selected at

each position. When only the inner icon box is lit,

the speaker is set for “small.” When the inner box

and the two outer boxes with circles inside them

are lit, the speaker is set for “large." When no

indicator appears at a speaker location, that

position is set for “none” or “no” speaker.

Note: These icons are available only when

making setup changes without the use of the full

OSD mode.

As an example, in the Figure below, all speakers

are set for “large,” and a subwoofer is set.

Delay Settings

Due the different distances between the listening

position for the front channel speakers and the

surround speakers, the amount of time it takes

for sound to reach your ears from the front or

surround speakers is different. You may

compensate for this difference through the use of

the delay settings to adjust the timing for the

specific speaker placement and acoustic

conditions in your listening room or home

theater.
