On

the

back

of

the

speaker,

near

the

bottom,

you

will

see

two

pairs

of

terminals.

Each

pair

has

1

red

terminal

(+)

and

1

black

ter-

minal

(-).

These

will

accept

a

number

of

different

connection

con-

figurations.

"Spade"

lugs

or

"Banana"

plugs

are

preferred

but

they

will

accept

bared

wire

up

to

4mm.

If

you

are

using

bared

wire,

use

the

hole

in

the

post

rather

than

wrapping

it

around

and

tightening.

WARNING:

MAKE

CERTAIN

THAT

ALL

STRANDS

ARE

NEATLY

TUCKED

INTO

THE

HOLE

TO

AVOID

SHORT

CIRCUITS.

If

you

are

not

bi-wiring

or

bi-amping,

either

the

upper

or

lower

pair

of

terminals

may

be

used.

Of

course,

the

connecting

strips

between

the

terminals

must

be

left

in

place.

Connect

the

red

(4-)

terminal

on

the

speaker

with

the

red

(4-)

terminal

on

the

back

of

your

amplifier

and

similarly

with

the

black.

If

these

connections

are

reversed

on

one

of

the

loudspeakers,

bass

output

will

drop

dramatically.

In

this

condition,

the

speakers

are

out

of

phase.

If

both

are

reversed,

bass

output

Is

unaffected

but

absolute

phase

Is

lost.

This

will

not

be

noticed

on

most

recordings

but

you

might

as

well

have

it

right.

WARNING:

IF

YOU

ARE

BI

-WIRING

OR

BI-AMPING

AND

ARE

UNCLEAR

ABOUT

ANY

ASPECT

OF

THE

FOLLOWING

SECTIONS,

CONSULT

YOUR

DEALER.

DON'T

GUESS,

YOU

CAN

DO

SERIOUS

DAMAGE

TO

YOUR

SYSTEM.

Remove

and

save

the

connecting

strips

between

the

two

pairs

of

terminals.

The

two

terminals

are

now

completely

isolated

from

each

other.

The

upper

pair

of

terminals

connects

to

the

tweeter

and

midrange

crossovers

and

the

lower

to

the

woofer

crossover

in

the

Sixty.

In

the

Fifty

the

lower

terminal

connects

to

the

woofer

cross-

overs

and

the

upper

to

the

tweeter.

Connect

the

appropriate

wires

to

the

appropriate

terminals

and

your

amplifier.

Pay

extra

attention

to

maintaining

correct

phase

as

above.

Errors

in

this

case can

intro-

duce

frequency

response

anomalies

and

prevent

accurate

imaging.

Woofers

Bi-amping

can

have

very

beneficial

effects.

However,

if

you

are

bi-

amping,

there

are

number

of

points

you

must

keep

in

mind

in

addi-

tion

to

those

mentioned

in

the

Bi-WIRING

section.

WARNING:

YOU

MUST

REMOVETHE

CONNECTING

STRIPS

BETWEEN

THE

TERMINALS.

FAILURE

TO

DD

THIS

CAN

DESTROY

YOUR

AMPLIFIERS

AND

MAYBE

SPEAKERS

AS

WELL.

DO

SD

NOW.

If

the

amplifiers

you

are

using

are

not

identical,

ascertain

the

following...

1.

That

the

amplifiers

have

the

same

polarity.

Some

amplifiers

invert

phase

and

this

condition

will

have

the

same

effect

as

mis-

wiring

in

the

bi-wiring

mode.

If

one

of

your

amplifiers

inverts

phase,

be

sure

to

invert

its

connection

to

its

corresponding

speaker

terminal.

That

is,

connect

its

red

(+)

terminal

to

the

black

(-)

termi-

nal

on

the

speaker.

2.

That

the

amplifiers

have

the

same

sensitivity.

That

is,

that

they

achieve

their

respective

rated

power

at

the

same

input

voltage.

A

better

alternative

is

to

use

power

amplifiers

that

have

input

attenua-

tors.

Care

must

be

taken

to

adjust

the

output

of

the

amplifiers

so

that

the

speakers

sound

as

balanced

as

possible.

Otherwise,

the

woofers

or

the

midrange

/tweeter

will

be

playing

too

loud

or

soft.

Naturally,

this

will

have

deleterious

effects

on

fidelity.

It

is

generally

recommended

that

the

more

powerful

amplifier

be

used

for

low

frequencies.

The

equipment

you

choose

to

complement

your

loudspeakers

will

have

a

direct

bearing

on

the

quality

of

sound

you

will

achieve.

As

your

loudspeaker

is

very

efficient,

it

is

not

necessary

to

use

high

powered

amplifiers

to

drive

them

to

realistic

levels..

Your

money

is

better

spent

on

quality

rather

than

high

"spec"

power.

Your

loud-

speakers

are

capable

of

the

highest

possible

performance

and

will

do

justice

to

the
