and music, may prefer that different bass management

be used when listening to music through a CD player

as opposed to a movie from a DVD player, VCR or

cable/satellite set-top. Also, you may wish to activate

or deactivate certain speakers for some sources. For

example, when listening to music CDs, you may wish

to have only the front left and right speakers active,

or for watching TV, you may wish to deactivate the

surround back speakers in favor of a 5.1-channel

configuration.

If you wish to customize the speaker settings for

each input, make certain that the

›

cursor is on the

BASS MGR

line, and press the

o

so that

INDEPENDENT

appears. When this

setting is entered by exiting the menu, you may need

to go back to the

INPUT

menu to select another

input, and then return to this menu page again to

change the settings for that input. Repeat the proce-

dure for any input where you wish to have a different

set of speaker configurations.

NOTE:

When the

INDEPENDENT

setting is

activated, you may assign different speaker size set-

tings to each input to accommodate different bass

management settings that match your preferences

with the type of program material normally used with a

particular source (for example, when movies are played

from DVD and music from a CD player). However, the

actual speaker crossover settings are set only once and

do not change with the input selection. The reason is

that, while bass management preferences may vary,

the actual speakers remain the same, regardless of the

bass-management and redirection settings.

Speaker Crossover Settings

When all initial speaker “size” settings have been

made, you now have the option to take advantage of

the AVR 140’s Quadruple Crossover system, which

allows individual crossover settings to be made for

each speaker grouping. In systems where full-range or

tower speakers are used for the front soundstage or

where different brands or models are in use at the

various speaker positions, this feature allows you to

customize the bass management and redirection cir-

cuits with a precision not previously possible.

The low-frequency crossover setting is determined by

the design of your speakers. Depending on the design

and driver complement of your speakers, it is usually

the lowest possible frequency the speaker is capable

of reproducing. Before making any changes to the

settings for the crossover point, we suggest that you

find the lowest frequency for the speakers in each of

the three groupings, front left/right, center and sur-

rounds, by looking at the specifications page of each

speakers’ owner’s manual, or by contacting your dealer

or the manufacturer’s customer service department or

Web site.You will need this figure to accurately config-

ure the next group of settings.

The factory default setting for all speaker positions is

100Hz. If that setting is acceptable for all channels,

then no adjustments are needed and you may skip

this section. However, if you wish to change one of the

settings, proceed to the

SPEAKERX-OVER

submenu by pressing the

and then press the

until the desired

setting appears. The available choices that determine

at which point low-frequency information will be sent

to the subwoofer, rather than to the main speaker

channel, are 40Hz, 60Hz, 80Hz, 100Hz, 120Hz,

150Hz and 200Hz. Pick the choice that is identical to

the information for the speakers, or if an exact match

is not possible, pick the closest choice that is ABOVE

the speaker’s low-frequency limit or crossover point to

avoid the creation of a low-frequency “hole” where

your system will have no bass information.

NOTE:

In cases where

LARGE

is selected as the

front channel speaker option and

LFE+L/R

is

selected as the subwoofer option, the front channel

sound information below the setting shown will be

sent BOTH to the front channel speakers and to

the subwoofer.

The crossover settings for the Left/Right, Center,

Surround and Surround Back speakers are used to

determine where bass information is sent when it is

derived from the main channels of a source.

The setting for the menu line shown as

LFE

is used

to impose a low-pass filter point for the information in

the Low Frequency Effects (LFE) channel that is a part

of Dolby Digital- and DTS-encoded source material.

While the LFE channel, which is the “.1” you see in

surround sound designations, is restricted to low fre-

quency sounds, some mixes may include information

that is higher in frequency than your subwoofer is

capable of reproducing. To prevent unwanted sounds

from being sent to subwoofers that cannot handle

them and which do not have a built-in low-pass filter,

the

LFE

option line enables you to select a setting

for the low-pass filter that is part of the subwoofer

feed from the LFE channel. The settings available are

the same as those tied to any one of the four available

speaker positions on this submenu. We recommend

that you use the frequency that is just slightly higher

than the upper capability limit of your subwoofer, as

shown in the sub’s Owner’s Manual.

When the cursor is on the

LFE

line, press the

to choose the appropriate setting.

When all speaker selections have been made, press

submenu.

Delay Settings

Due to the different distances between the listening

position for the front channel speakers and the sur-

round speakers, the amount of time it takes for sound

to reach your ears from the front versus surround

speakers differs. You may compensate for this differ-

ence 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.

The AVR 140’s advanced software enables you to

quickly and easily set delay times without having to

calculate them using a complex formula. All you need

to do is measure the approximate distance between

your listening position and each of the speakers in

your system. When you enter those distances into

the AVR’s memory as shown below, the AVR’s micro-

processor calculates the proper delay time. The meas-

urements need not be accurate to the inch, as the

system is designed to accommodate a typical listening

area rather than require the precise measurement to

one “sweet spot” position.

Due to the differences in the way each surround

mode operates, the delay settings must be established

individually for each surround mode. However, once

the delay settings are configured for the version of the

surround mode with the most channels, they need not

be entered again for a version of that mode with fewer

channels. For example, once the delay settings are

established for Dolby Pro Logic IIx – Movie, they will

be carried over to Dolby Pro Logic II – Movie mode.

However, you will need to enter the delay settings sep-

arately for each variant mode, such as Dolby Pro

Logic IIx – Music, Dolby Pro Logic IIx – Game, Dolby

Pro Logic, Dolby 3 Stereo and Dolby Digital EX.
