Pyramid PB2415X Installation guide

Congratulations

on

purchasing the High Speed Power Amplifier. The amplifier

has been designed using the latest electronic technology available, allowing

you to produce high quality stereo reproduction in mobile applications. This

system provides you with low harmonic distortion, a huge considerable amount

of

reserve voltage and high temperature stability.

Just

enjoy

the

perfect

sound

this

amplifier

takes

to

you!

INSTALLATION

*

Since

the

amplifier

is

sensitive

to

electrical

and

motor

noise

and

interference

from

the

amplifier

may

affect your

radio

reception, try

to

mount

it

at

least 3 feet

away

from

the

receiver.

Good

locations include

under

a

seat,

in

the

trunk

or

hatch

area.

*

Please

remember

this

is

a

high

power

unit

which

generates

high

electrical

energy

and

heat.

Therefore

be

sure

to

install

the

unit

in

a

place

with

sufficient airflow, a

minimum

of dust

and

no

moisture. Allow

enough

space

around

the

cooling

fins

to

permit

reasonable

airflow

and

cooling.

II

is

important

to

ensure

that

the

cooling

fins

of

the

heat

sink

are

not

against a

panel

or

a surface preventing air circulation.

*

Never

mount

the

amplifier

in

a location that

is

subject

to

direct sunlight

or

exposed

to

moisture.

Be

sure

to

mount

the

amplifier

to

a strong, solid surface

which

will

not

give

way

under

the

stress of a

sudden

stop

or

accident.

*

When

mounting

the

amplifier

on

a

side

wall, try

to

position it

so

that

the

slots

in

the

cooling

fins

are

vertical. Amplifier

should

not

be

mounted

on

the

bottom

of a

rear

deck

with

the

fins

facing

down

because

the

heat

will

radiate

back

up

into

the

amplifier.

Leave

yourself

enough

room

on

either

side

of

the

amplifier

to

make

all

the

wire connections

and

adjust

the

controls. If

you

have

a subwoofer

box

in

your vehicle,

you

can

mount

the

amplifier

on

the

outside of

the

box.

Caution:

If

you

are

mounting

the

amplifier

to

the

vehicle's

floor,

check

beneath

the

car

to

be

sure

your

screws

won't

puncture

a

brake

or

gas

line.

WARNING!

Continuous

exposure

to

sound

pressure

levels

over

lOOdB

may

cause

permanent

hearing

loss.

High

power

auto

sound

system

may

produce

sound

pressure

levels

well

over

l30dB,

use

common

sense

and

practice

safe

sound

please!

IMPORTANT!

Before

making

any

connections, disconnect

the

car's

battery until

the

installation

is

completed

to

avoid

possible

damage

to

the

electrical

system

*

The

+

12V

DC

power

cable

should

be

heavy

gauge

stranded copper cable

with

heavy

insulation,

since

it

draws

power

directly

from

the

positive battery terminal.

Select

the

cable

gauge

at

least 10mm'.

And

the

ground

cable

gauge

should

be

the

same

as

the

+

12V

DC.

* Connect

the

+12V

Power

terminal

to

the

battery

(+)

position terminal.

An

in-line

fuse

must

be

installed

in

the

+12V

power

cable near

the

battery

less

than

50mm.

Without one,

an

accidental short circuit

could

pose

a fire

hazard

and

damage

your

amplifier. Connect

the

fuse

holder

to

battery, however,

do

not

install

fuse

at

this

time.

* Connect

the

GROUND

Power

terminal direclly

to

the

battery

(-)

position terminal

or

the

car chassis.

Ensure

that all paint or other insulation

is

remove

from

around

the

hole

area,

and

using

self tapping

screw,

securely affix

the

bare

wire

ends

to

the

vehicle chassis.

Use

as

short

as

possible.

*

Many

radio's

and

other

music

sources

have

an

output terminal for connection of

the

remote

turn

on

of

the

power

amplifier.

CONNECT

the

output terminal

to

the

amplifier

REM

control jack. If a

radio

doesn't

have

a

remote

turn

on

feature,

you

can

connect

the

REM

pole

to

external

switch

for positive +12V ON/OFF.

*

To

help

minimize interference, it

is

best

to

run

the

power

cables

along

the

opposite

side

from

the

audio

cables.

Caution:

The

power cables must

be

connected tightly. A loose connection may

cause

malfunctions or interference noise

or

distortion.
