on the remote to select a parameter. Use the

+/– buttons to change the selected param-

eter as follows:

• PANORAMA: The Panorama option ex-

tends the front stereo image to include the

surround speakers for a dramatic “wrap-

around” effect. The options are OFF or

ON.

• DIMENSION: The Dimension option al-

lows you to gradually adjust the sound-

ﬁeld towards the front or towards the rear.

There are seven incremental settings from

0 to 6. A setting of 0 shifts the soundﬁeld

towards the rear for maximum surround ef-

fect. A setting of 6 shifts the soundﬁeld to

the front for minimum surround effect. The

default setting of 3 provides a “neutral”

balance between the two extremes.

• CENTER WIDTH: The Center Width op-

tion allows you to spread the signal in-

tended for the center speaker to the left

and right front speakers, widening the

perceived soundﬁeld. There are eight in-

cremental settings from 0 to 7. With the

default setting of 0, there is 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 between the two extremes.

Select GAME to optimize for Dolby Surround

encoded video games.

Select PRO LOGIC for original Dolby Pro

Logic decoding. Typically, Pro Logic II (Cin-

ema or Music modes) will provide better sur-

round performance, even with older source

material. Original Pro Logic mode provides

5.1 channel surround sound, even on 6.1/7.1

channel systems.

When you have completed all the desired ad-

justments, 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).

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 matrix decoding algorithms to derive a

center channel and surround channels from

2-channel 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 settings.

• 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 in-

cluding 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-1058 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-1058 the number of speak-

ers in your system and how bass should be

distributed 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

surround). 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

setting 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

redirection. All ﬁve speakers play the

normal bass recorded in their respective

channels. 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 ca-

pabilities of the other speakers and the

ampliﬁers driving them.

• LARGE front, center, surround

speakers, no subwoofer. The nor-

mal bass from the front, center, and sur-

round channels is played in its respective

speakers. With no subwoofer, the LFE bass

is redirected to all ﬁve LARGE speakers.

This places signiﬁcant demands on these
