Here following are explained two types of connections that

improve sound quality. The speakers in these explanations have

low and mid/high input jacks that support a bi-amp connec-

tion. To determine whether or not your speakers support a bi-

amp connection, check in the instruction manual that came

with your speakers or contact the manufacturer.

BI-WIRING CONNECTION

A bi-wiring connection separately connects the low and mid/

high jacks of the speaker to the amplifier using separate

speaker cables. Because separate cables are used for low

and mid/high sounds, the return current generated in the low

speaker causes little interference with the mid/high speaker.

The PM-11S1 and speakers of Connection Example 1 use a

bi-wiring connection, therefore also refer to that page for help.

COMPLETE BI-AMP CONNECTION

Proposed by Marantz, the complete bi-amp connection en-

hances the bi-wiring connection. With it, the low and mid/high

amplifiers are separate and independent of the preamplifier,

therefore interference between low and mid/high sounds is

reduced to a minimum. As a result, a wide sound environment

can be reproduced. Connection Example 3 connects two PM-

11S1s by FCBS in a complete bi-amp connection, therefore

also refer to that page for help.

SPEAKER POSITIONING FOR SUPER

AUDIO MULTI-CHANNEL SOUND

In order to enjoy Super Audio CD multi-channel sound with

the best possible acoustics, it is recommended to position

speakers as specified in ITU-R BS.775-1 of the International

Telecommunication Union (ITU). Super Audio CD multi-chan-

nel discs are recorded and mixed so as to achieve the opti-

mum effect with a speaker system laid out as specified in ITU-

R BS.775-1.

• With Super Audio CD multi-channel discs, the music sig-

nals are basically recorded using 5 channels (3 - 6 chan-

nels sometimes), but in some cases, LFE (for subwoofer) is

recorded as a sixth channel. Each disc indicates how many

channels have been recorded on it.

• The basic layout is 3 speakers in the front and 2 in the back

since multi-channel discs usually have 5 channels. The 2

front, 1 center and 2 surround (rear) speakers should be set

in a circle around the listening point as shown below. If us-

ing speakers of differing sizes, adjust volume balance from

the amplifier.

• The location of the subwoofer in the figure is just for ex-

planatory purposes. It can be located anywhere in the room.

For connection and positioning instructions, see the instruc-

tion manual that came with the subwoofer.

systems.”
