INSTALLATION

GUIDELINES

Connecting

the

GND

(GROUND)

screw

terminal

Connecting

a

mixer

or

preamplifier

may

cause

excessive

noise

or

hum

in

the

amplifier

output.

To

prevent

this,

connect

one

end

of

a

low

-capacitance

shield

wire

to

the

amplifier's

ground

screw

(on

the

rear

panel).

Then

connect

the

other

end

of

this

wire

to

the

ground

terminal

on

the

mixer

or

preamplifier

enclosure.

Inputs

Your

amplifier

can

be

operated

in

Stereo

or

Mono

mode,

depending

on

the

input

source.

If

the

input

signal

is

mono,

connect

the

source

via

the

LEFT

input

only

(also

marked

"MONO"

on

the

back

of

amplifier).

Then

slide

the

STEREO/MONO

selector

and

the

signal

will

Ohm,

or

16

speakers

to

Channel

A

and/or

Channel

B

of

the

amplifier.

If

you

connect

two

pairs

of

speakers,

be

sure

to

follow

these

guidelines:

•

Speakers

which

are

connected

to

the

same

channel

are

part

of

a

pair,

and

must

be

of

the

same

impedance.

•

Speakers

connected

to

different

channels

are

NOT

part

of

a

pair,

and

can

be

of

different

impedances.

1.

Prepare

the

speaker

wire

by

removing

about

1

inch

of

insulation

from

the

end

of

speaker

wire

you

intend

to

connect

to

the

amplifier.

Then

twist

the

exposed

wire

to

secure

all

the

wire

strands.

NOTE:

Use

18

-gauge

speaker

wire

for

lengths

up

to

25

feet;

16

-gauge

wire

for

lengths

over

25

feet.

It

is

recommended

that

you

use

the

shortest

length

of

wire

possible.

2.

Connect

the

speaker

wire

to

the

speaker's

positive

and

negative

terminals.

NOTE:

Most

speaker

terminals

are

either

color

-coded

or

have

a

mark

that

indicates

the

terminal's

polarity.

Usually

positive

terminals

are

red

or

have

a

plus

symbol

(+),

and

negative

terminals

are

black

or

have

a

minus

symbol

(-).

3.

Connect

the

speaker

wires

to

the

amplifier's

left

and

right

speaker

terminals

according

to

the

color

polarity.

Using

headphones

To

listen

privately,

or

to

monitor

sound

sources,

connect

a

pair

of

low

impedance

stereo

headphones

(not

supplied)

with

6.35mm

plug

into

the

PHONES

jack

on

the

amplifier

front

panel.

Please

listen

safely.

Follow

these

recommendations:

Do

not

listen

at

extremely

high

volume

levels.

Extended,

high

-volume

listening

can

lead

to

permanent

hearing

loss.

Always

start

with

the

volume

control

set

to

a

LOW

level

BEFORE

you

put

the

headphones

on.

Then

gradually

increase

the

voulume

as

necessary.

Connecting

to

standard

AC

power

After

making

all

other

connections,

set

the

POWER

switch

to

OFF

position.

Then

connect

the

power

cord

to

a

standard

AC

outlet.

Mounting

the

amplifier

This

amplifier

is

designed

to

accept

standard

rack

mounting

installations.

Two

slots

on

each

end

of

the

front

panel

make

it

suitable

for

such

an

installation.

Tightly

secure

four

mounting

screws

(not

supplied)

through

these

four

slots

and

into

your

standard

electronics

equipment

rack.

Turning

the

amplifier

on

1.Turn

on

the

audio

input

source

equipment

which

is

connected

to

the

amplifier

INPUT

jack.

2.Set

the

amplifier's

left

and

right

output

level

gain

controls

to

the

minimum

level

settings.

3.Press

the

power

switch

to

turn

the

amplifier

on.

Using

the

power

meter

The

meter

LED

dispaly

position

indicate

the

amplifier

output

power.

Using

the

left

and

right

Output

Level

controls

Rotate

output

level

gain

clockwise

to

increase,

or

counterclockwise

to

decrease

the

output

power.

To

get

the

best

performance

with

the

leaset

sound

distortion,

always

adjust

the

output

level

gain

so

the

meter's

level

indication

does

not

continuously

exceed

to

the

extreme

right.

CAUTION:It

is

possible

to

overdrive

the

amplifier

by

setting

output

level

gain

too

high,

which

may

cause

damage

or

failure.

About

the

internal

clip

circuitry

Special

clip

circuitry

incorporated

into

your

amplifier's

design

protects

the

amplifier

and

speaker

system

from

being

damaged

from

overdriving

power.

Under

normal

conditions,

the

amplifier's

clip

indicator

will

flicker

as

the

output

power

momentarily

exceeds

the

level

as

set

by

the

output

level

gain

selector.

However,

under

excessive

output

conditions,

the

clip

indicator

lights

remain

on

continuously,

altering

you

that

the

special

clip

circuitry

has

become

active.

When

this

occurs,

you

should

simply

reduce

the

output

power

level

by

rotating

the

Master

Volume

control

counterclockwise.

Using

the

A/B

Speaker

Selector

Switch

You

can

listen

to

speakers

on

set

A

or

set

B

individually

or

simultaneously.

Simply

push

in

or

out

the

desired

speaker

set

to

make

your

selection.

CAUTION:If

the

impedance

of

your

speakers

is

4

OHMS,

do

not

use

both

the

speaker

A

and

speaker

B

terminal

at

the

same

time

as

the

net

impedance

may

be

low

enough

to

damage

your

amplifier.

Caring

for

your

Pyle

Pro

Amplifier

Your

Pyle

Pro

Amplifier

is

an

example

of

superior

design

and

craftsmanship.

The

following

suggestions

will

help

you

care

for

your

amplifier

so

you

can

enjoy

years

of

use:

•

Keep

the

amplifier

dry.

If

it

gets

wet,

wipe

immediately.

•

Use

the

amplifier

only

in

well

-ventilated

installations.

•

Handle

the

amplifier

away

from

dust

and

dirt.

•

Wipe

occasionally

with

a

damp

cloth

to

keep

it

looking

new.

Do

not

use

harsh

chemical,

solvents

or

detergents!

Replacing

a

fuse

This

amplifier

requires

a

fuse

with

the

proper

rating

for

protection

from

power

surges

and

short

circuits.

If

the

amplifier

suddenly

turns

off

or

will

not

turn

on,

the

fuse

is

properly

blown.

Remove

the

old

fuse

and

replace

it

with

an

identical,

serviceable

fuse:

PT

-2801

=

7A

(110-120V)

OR

3.5A

(220-240V)

PT

-2401

=

5A

(110-120V)

OR

2.5A

(220-240V)

CAUTION:Never

use

a

fuse

with

a

higher

rating.
