CONNECTING

THE

EQUALIZER

IT

IS

MOST

IMPORTANT

THAT

YOU

FOLLOW

THESE

IN-

STRUCTIONS

FOR

OPTIMUM

PERFORMANCE

OF

YOUR

901

SERIES

IV

SPEAKER

SYSTEM.

1.

Using

The

Tape

Monitor

Circuit

The

connection

methods

described

in

this

section

can

be

us-

ed

with

virtually

all

integrated

amplifers,

preamplifiers,

and

receivers.t

Using

the

tape

monitor

circuit

has

two

advan-

tages:

When

using

conventional

loudspeakers

or

head-

phones,

the

tape

monitor

circuit

allows

disconnection

of

the

Active

Equalizer

by

turning

off

the

tape

monitor

switch

on

your

control

amplifier;

this

is

important

because

conven-

tional

speakers

and

headphones

should

not

be

used

with

the

Active

Equalizer.

(See

SECTION

IV.)

Also,

optimum

system

noise

performance

is

obtained

when

connecting

the

equalizer

in

the

tape

monitor

circuitry.

When

using

this

procedure,

you

should

realize

that

the

901

equalizer

is

being

connected

to

your

equipment

as

if

it

were

a

tape

recorder,

using

the

tape

monitor

connections

of

your

control

amplifier.

NOTE:

Check

your

control

equipment

to

determine

if

your

unit

has

any

additional

switching

flexibility.

Some

recently

introduced

units

now

feature

switching

facilities

called

Tape

Monitor

3,

External

Equalizer/Processing,

or

Noise

Reduction

Connections.

The

equalizer

can

be

connected

to

these

terminals

allowing

greater

system

flexibility

if

re-

quired.

fro

make

connection

easier,

we

are

going

to

refer

to

all

of

these

various

corn

-

ponents

as

the

"control

amplifier."

Referring

to

FIGURE

4,

connect

the

Active

Equalizer

accor-

ding

to

the

following

instructions:

a.

Turn

off

all

power

to

your

high-fidelity

system.

b.

If

you

have

a

tape

recorder,

disconnect

it

from

your

control

amplifier.

(Instructions

in

SECTION

IV

will

tell

you

how

to

recon-

nect

your

tape

recorder

to

the

system

after

the

equalizer

has

been

installed.)

c.

Using

one

of

the

cables

supplied

with

the

equalizer,

con-

nect

the

LEFT

channel

OUTPUT

of

the

equalizer

to

the

LEFT

or

"A"

channel

of

the

tape

monitor

circuit

of

your

control

amplifier.

(This

terminal

may

also

be

labeled

PLAYBACK

or

TAPE

IN.)

d.

Connect

the

RIGHT

channel

OUTPUT

of

the

equalizer

to

the

RIGHT

or

"B"

channel

tape

monitor

connection

of

your

control

amplifier.

e.

Connect

the

LEFT

channel

INPUT

terminal

of

the

equal-

izer

to

the

LEFT

or

"A"

channel

TAPE

RECORD

connec-

tion

of

your

control

amplifier.

(This

terminal

may

also

be

labeled

TAPE

OUT

or

REC

OUT.)

f.

Connect

the

RIGHT

channel

INPUT

connection

to

the

RIGHT

or

"6"

channel

TAPE

RECORD

connection

of

your

control

amplifier.

g.

Plug

the

ac

power

cord

of

the

equalizer

into

a

"switched"

ac

outlet

on

your

control

amplifier

so

that

the

equalizer

will

automatically

be

turned

on

or

off

with

the

power

switch

of

your

equipment.

If

the

preceding

steps

are

unclear,

it

may

be

due

to

the

dif-

ferent

nomenclature

used

by

various

manufacturers

of

amplifying

equipment.

Consult

your

control

amplifier's

in-

struction

manual

and

refer

to

the

section

describing

the

connection

of

a

tape

recorder.

Remember,

the

equalizer

is

connected

just

like

a

tape

recorder.
