FIELD

CAUTION!

Do

not

locate

sensitive

high-gain

equipment

such

as

preamplifiers

or

tape

decks

directly

above

or

below

the

unit.

Because

this

amplifier

has

a

high

power

density,

it

has

a

strong

magnetic

field

which

can

induce

hum

into

unshielded

devices

that

are

located

nearby.

The

field

is

strongest

just

above

and

below

the

unit.

If

an

equipment

rack

is

used

,

we

recommend

locating

the

amplifier(s)

in

the

bottom

of

the

rack

and

the

preamplifier

or

other

sensitive

equip-

ment

at

the

top

.

and

(2)

this

device

must

accept

any

interference

received,

including

interference

that

may

cause

undesired

operation

.

CAUTION:

Changes

or

modifications

not

expressly

approved

by

the

party

responsible

for

compliance

could

void

the

the

equipment.

NOTE

:

This

equipment

has

been

tested

and

found

to

comply

with

the

limits

for

a

Class

B

digital

device,

pursuant

to

part

15

of

the

FCC

Rules

.

These

limits

are

designed

to

provide

reasonable

protection

against

harmful

interference

in

a

residential

installation.

This

equip-

ment

generates

,

uses

,

and

can

radiate

radio

frequency

energy

and,

if

not

installed

and

used

in

accordance

with

the

instruction

manual

,

may

cause

harmful

interference

to

radio

com-

munications.

However,

there

is

no

guarantee

that

interference

will

not

occur

in

a

particular

installation

.

If

this

equipment

does

cause

harmful

interference

to

radio

or

television

recep-

tion

,

which

can

be

determined

by

turning

the

equipment

by

one

or

more

of

the

following

measures

:

•

Reorient

or

relocate

the

receiving

antenna.

•

Increase

the

separation

between

the

equipment

and

the

equipment

into

an

outlet

on

a

2.1 UnpackYourAmplifier

Please

unpack

and

inspect

your

amplifier

for

any

damage

that

may

have

occurred

during

transit.

If

damage

is

found,

notify

the

transportation

company

immediately.

Only

you

can

initiate

a

claim

for

shipping

damage.

Crown

will

be

happy

to

help

as

needed.

Save

the

carton

as

evidence

of

damage

for

the

shipper's

inspection.

We

also

recommend

that

you

save

all

packing

materials

so

you

wi

11

have

them

if

you

ever

need

to

transport

the

2.8 Connectto AC Mains

Connect

your

amplifier

to

the

AC

mains

power

source

(power

outlet)

with

the

supplied

AC

power

cordset.

First,

connect

the

IEC

end

of

the

cordset

to

the

IEC

connector

on

the

amplifier;

then,

plug

the

other

end

of

the

cordset

to

the

AC

mains.

WARNING

:

The

t

hird

prong

of

this

connector

(ground)

is

an

important

safety

feature

.

Do

not

attempt

to

disable

this

gro

u

nd

connection

by

using

an

adapter

or

other

methods

.

Amplifiers

don't

create

energy

.

The

AC

mains

voltage

and

current

must

be

sufficient

to

deliver

the

power

you

expect.

You

must

operate

your

amplifier

from

an

AC

mains

power

source

with

not

more

than

a

10%

variation

above

or

a

15%

variation

below

the

amplifier's

specified

line

voltage

and

within

the

specfied

frequency

requirements

(indicated

on

the

amplifier's

back

panel

label).

If

you

are

unsure

of

the

output

voltage

of

your

AC

mains,

please

consult

your

electrician.

Wiring

2.9 Protecting Your Speakers

It's

wise

to

avoid

clipping

the

amplifier

signal.

Not

only

does

clipping

sound

bad,

it

can

damage

high-frequency

drivers.

The

built-in

clip

limiter

prevents

clipping.

Also,

avoid

sending

strong

subsonic

signals

to

the

amplifier.

High-level,

low-frequency

signals

from

breath

pops

or

dropped

microphones

can

blow

out

drivers.

To

prevent

subsonic

signals,

use

System

Architect

software

to

insert

a

high

pass

filter

(see

Section

4.1.6).

Alternatively,

switch

in

high

pass

filters

at

your

mixer.

Set

the

filter

to

as

high

a

frequency

as

possible

that

does

not

affect

your

program.

For

example,

try

35

Hz

for

music

and

75

Hz

for

speech

.

On

each

mixer

input

channel,

set

the

filter

frequency

just

below

the

lowest

fundamental

frequency

of

that

channel's

instrument.

2.10 Startup Procedure

Use

the

following

procedure

when

first

turning

on

your

amplifier:

1.

Turn

down

the

level

of

your

audio

source.

2.

Turn

down

the

level

controls

of

the

amplifier.

3.

Turn

on

the

"Power"

switch.

The

Power

indicator

should

glow.

4.

Turn

up

the

level

of

your

audio

source

to

an

optimum

level.

5.

Turn

up

the

Level

controls

on

the

amplifier

until

the

desired

loudness

or

power

level

is

achieved.

NOTE:

In

Bridge-Mono

mode,

only

the

Channel

1

Level

control

is

functional

(unless

you

make

an

alternate

setting

with

the

Y

processing

block).

When

Bridge

Preset

is

used,

both

Level

controls

are

functional.

6.

Turn

down

the

level

of

your

audio

source

to

its

normal

range.

If

you

ever

need

to

make

any

wiring

or

installation

changes,

don't

forget

to

disconnect

the

power

cord.
