The SPEAKER SETUP menu is used to config-

ure the RSP-1066 for use with your specific

loudspeakers. The menu is accessed from the

MAIN menu.

Home theater systems vary in the number of

speakers and the bass capabilities of those

speakers. The RSP-1066 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 RSP-1066 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 sound system. The first is normal 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

have a Low Frequency Effects (LFE) channel –

the .1 channel. This bass channel, typically

played by a subwoofer, 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 informa-

tion away from all SMALL speakers and sends

it to the LARGE speakers and/or the SUB-

WOOFER.

Four examples illustrate the principles behind

bass management:

• A system with five LARGE speakers and a

subwoofer: This system requires no bass

redirection. All five speakers play the nor-

mal bass recorded in their respective chan-

nels. The subwoofer plays only the LFE

channel bass. This may not be the most ef-

ficient use of system resources. Depend-

ing on the soundtrack, there may be mini-

mal use of the LFE channel, so the subwoofer

would be underutilized. Meanwhile the

normal bass places higher demands on the

capabilities of the other speakers and the

amplifiers driving them.

• A system with LARGE front, center, and

surround speakers, but no subwoofer. The

normal bass from the front, center, and

surround channels is played in its respec-

tive speakers. With no subwoofer, the LFE

bass is redirected to all five LARGE speak-

ers. This places significant demands on these

speakers and their amplifiers, as they must

play their own normal bass plus the very

demanding LFE bass.

• A system with LARGE front speakers, SMALL

center and surround speakers, and a sub-

woofer. The normal bass from the SMALL

center and surround speakers is redirected

to the LARGE front speakers and the sub-

woofer. The LARGE front speakers play their

own normal bass plus the redirected bass

from the SMALL speakers. The subwoofer

plays the LFE bass plus some of the redi-

rected bass from the SMALL center and

surround channels. This might be an ap-

propriate configuration with a pair of very

capable front speakers driven by a large

separate power amplifier.

• A system with all SMALL speakers and a

subwoofer. The normal bass from all chan-

nels is redirected to the subwoofer, which

also plays the LFE bass. The subwoofer

handles ALL of the bass in the system, while

the other speakers benefit from the added

dynamic range and reduced strain of not

having to play low bass. This configura-

tion realizes the full benefits of bi-amping:

bass is played by the speaker most suited

to do so, the other speakers play louder

with less distortion, and the need for am-

plifier power is reduced. This is the most

popular home theater configuration and

should be strongly considered even if the

speakers are physically large and capable

of playing low bass. This configuration is

particularly advantageous when driving the

speakers with moderate power amplifiers.

NOTE

: An alternative configuration for setting

up a satellite/subwoofer package as the front

speakers: follow the speaker manufacturer’s

instructions, connecting the high-level inputs

of the powered subwoofer directly to the

speaker outputs of front amplifier and con-

necting the satellite speakers to the

subwoofer’s own crossover. In this arrange-

ment, the speakers would be classified as

LARGE and the subwoofer setting would be

OFF for all surround modes. No information

will be lost during playback because the sys-

tem knows to redirect the bass information to

the front LARGE speakers. While this configu-

ration may ensure correct satellite speaker

operation by using the speaker manufacturer’s

own crossovers, it has some disadvantages

in terms of system calibration.

The following speaker options are available:

FRONT SPEAKERS (small/large): This

menu setting determines what kind of main front

left and right speakers you are using. Use the

LARGE setting to have the front speakers play

low bass. Use the SMALL setting to redirect

normal bass away from these speakers to a

subwoofer.

CENTER SPEAKER(S) (small/large/

none): Use the LARGE position (not available

with SMALL front speakers) to have the cen-

ter speaker play low bass. Use the SMALL po-

sition if your center channel speaker has more

limited low frequency capability, or if you prefer

that the bass be sent to the subwoofer. Select

the NONE setting if your system does not have

a center channel speaker (the surround modes

will automatically divide all center channel

information equally between the two front

speakers, creating a phantom center channel).

SURROUND SPEAKERS (small/large/

none): Select the LARGE setting (not avail-

able with SMALL front speakers) to have the

surround speakers play low bass. If your rear

speakers have limited bass capability or if you

would prefer that the bass go to a subwoofer,

use the SMALL setting. If your system has no

rear surround speakers, select the NONE

setting (surround channels are added to the

front speakers so none of the recording is lost).
