no center width spreading and all of the center

channel information is sent to the center

speaker. The maximum setting of 7 shifts all

of the center channel signal to the left and

right speakers, essentially muting the center

speaker and maximizing the soundfield width.

Other settings provide incremental steps be-

tween the two extremes.

When you have completed all the desired

adjustments, highlight the INPUT SETUP MENU

line at the bottom of the screen and press the

ENTER button to return to the INPUT SETUP

menu (or just press the ENTER button).

DTS Neo:6

MODE:Cinema

INPUT SETUP MENU

When DTS Neo:6 is selected as the default

surround mode on the INPUT SETUP menu,

there are additional option settings and pa-

rameters available to optimize the surround

decoding for various types of recordings, music

or movie soundtracks. DTS Neo:6 uses ma-

trix decoding algorithms to derive a center

channel and surround channels from 2-chan-

nel source material.

In DTS Neo:6 surround mode, there will only

be one choice available on the sub-menu:

selecting CINEMA or MUSIC modes. Use the

+/– buttons on the remote to change the set-

tings.

• Select CINEMA to optimize the DTS Neo:6

decoding for movie soundtracks.

• Select MUSIC to optimize the DTS Neo:6

decoding for musical recordings.

When you have completed the setting, high-

light the INPUT SETUP MENU line at the bot-

tom of the screen and press the ENTER but-

ton to return to the INPUT SETUP menu (or just

press the ENTER button).

Configuring

Speakers and Audio

This section of the setup process covers items

concerning audio reproduction such as the

number of speakers, bass management includ-

ing subwoofer crossovers, establishing equal

output levels for all channels, delay settings,

and tone contour settings.

Understanding Speaker

Configuration

Home theater systems vary in the number of

speakers and the bass capabilities of those

speakers. The RSX-1056 offers surround modes

tailored to systems with various numbers of

speakers and bass management features which

send bass information to the speaker(s) best

able to handle it – subwoofers and/or large

speakers. For optimum performance, you must

tell the RSX-1056 the number of speakers in

your system and how bass should be distrib-

uted among them.

NOTE

: There are two types of bass in a sur-

round system. The first is bass recorded in each

of the main channels (front, center, and sur-

round). This bass is present in all recordings

and soundtracks. In addition, Dolby Digital 5.1

and DTS 5.1 recordings may have a Low Fre-

quency Effects (LFE) channel – the .1 channel.

This LFE channel, typically played by a sub-

woofer, is used for effects such as explosions

or rumble. The use of the LFE channel will vary

from soundtrack to soundtrack. Recordings that

are not encoded in Dolby Digital or DTS do

not have the LFE channel.

The following configuration instructions refer to

LARGE and SMALL speakers, referring more

to their desired bass configuration than their

physical size. Specifically, use the LARGE set-

ting for speakers that you want to play deep

bass signals. Use the SMALL designation for

speakers that would benefit from having their

bass sent to more capable speakers. The bass

management system redirects bass information

away from all SMALL speakers and sends it to

the LARGE speakers and/or the SUBWOOFER.

It may be useful to think of LARGE as “full-range”

and SMALL as “high-pass filtered.”

Four typical examples of the many possible

system configurations illustrate the principles

behind bass management:

• Five LARGE speakers and sub-

woofer: This system requires no bass re-

direction. All five speakers play the nor-

mal bass recorded in their respective chan-

nels. The subwoofer plays only the LFE

channel bass. Depending on the

soundtrack, there may be minimal use of

the LFE channel, so the subwoofer would

be under utilized. Meanwhile the normal

bass places higher demands on the capa-

bilities of the other speakers and the am-

plifiers driving them.

• LARGE front, center, surround

speakers, no subwoofer. The normal

bass from the front, center, and surround

channels is played in its respective speak-

ers. With no subwoofer, the LFE bass is re-

directed to all five LARGE speakers. This

places significant demands on these speak-

ers and their amplifiers, as they must play

their own normal bass plus the very demand-

ing LFE bass.

• All SMALL speakers and subwoofer.

The normal bass from all channels is redi-

rected to the subwoofer, which also plays

the LFE channel. The subwoofer handles

ALL of the bass in the system. This configu-

ration provides several benefits: deep bass

is played by the speaker most suited to do

so, the main speakers may play louder with

less distortion, and the need for amplifier

power is reduced. This configuration should

be used with bookshelf-size or smaller main

speakers. It should also be considered in

some cases with floorstanding front speak-

ers. This configuration is advantageous

when driving the system with moderate

power amplifiers.

• LARGE front speakers, SMALL cen-

ter and surround speakers, and a

subwoofer. The normal bass from the

SMALL center and surround speakers is re-

directed to the LARGE front speakers and

the subwoofer. The LARGE front speakers

play their own normal bass plus the redi-

rected bass from the SMALL speakers and

LFE bass. The subwoofer plays the LFE bass

plus the redirected bass from all of the other

channels. This might be an appropriate con-

figuration with a pair of very capable front

speakers driven by a large power ampli-

fier. A potential disadvantage with mixed
