LED

TUBE

INSTALLATION

(OPTIONAL)

These

Polk

Audio

amplifiers

have

been

designed

with

a

custom

heat

sink

that

can

accommodate

two

(optional-not

supplied)

VARAD

LED

tubes.

1.

Before

installing

the

LED

tubes,

remove

and

discard

the

mounting

feet

from

the

VARAD

LED

tubes.

2.

Slide

each

LED

tube

assembly

into

your

Polk

Audio

amplifier

heat

sink.

Ensure

that

the

LEOs

are

facing

out

for

optimal

visibility.

The

wires

from

the

LEO

tube

assembly

should

be

on

the

signal

input

end

of

the

amplifier.

The

Black

wire

from

the

LEO

tube

is

ground

and

the

Black/White

wire

from

the

LED

tube

is

power.

3.

Run

the

two

wires

from

the

tube

assembly

and

connect

them

to

the

4-pin

LED/FAN

input

connec-

tor.

Refer

to

the

LEO/FAN

harness

diagram

given

earlier

in

this

manual.

NOTE:

If

the

optional

fan

IS

NOT

being

used,

we

recom-

mend

that

the

second

LEO

tube

be

wired

to

this

circuit.

If

the

optional

fan

is

being

used,

we

recommend

that

the

second

LED

tube

be

wired

in

parallel

with

the

first

LEO

tube.

SPECIFICATIONS

SUBSONIC

FILTER

ADJUSTMENT

(PA1100.5

only)

This

amplifier

uses

a

subsonic

filter

to

maximize

the

perfor-

mance

of

a

subwoofer.

The

subsonic

filter

is

a

high-pass

filter

that

removes

unwanted

bass

output

at

very

low

frequencies

form

the

woofer.

This

increases

the

output

of

a

subwoofer

by

as

much

as

3

dB

by

increasing

the

mechanical

power

handling

of

the

subwoofer.

Depending

on

the

type

of

enclosure

the

subsonic

filter

can

increase

the

useable

low

frequency

output

by

an

additional1OdB!

Acceptable

boost

levels

are

determined

by

the

type

of

enclosure

used,

wattage

of

the

amplifier,

and

the

subwoofer's

excursion

capability.

The

following

guidelines

should

be

used

for

proper

set

up

of

the

subsonic

filter

to

provide

optimum

performance

and

reliability

from

your

system.
