levels

demanded

of

today,s

equipment.

Each

pOLyTONE

ieakers

are

capable

of

handling

extreme

power.

They

are specially

designed,

utilizing

a high-temperature

expoxy..

However,

when

using

the

ampl-ifier

or long

periods

of

time

at

any

overdriven,

level,

the

power

watts. use

good

sense.

6. Minimum exterior ipeaker impedance is 4 ohms. lf improper

impedance

is used

the

amptifier

will

operate

extremely

hot,

which

could

cause

damage.

Much

better

results

can

be

achieved

by

using

our SIDEKICK

abinet.for

CONTOUR:

when

CONTO(R,

you

will boost

different

upper frequen-

cies as

you

18.

BASS DRIVE: uming up the

BASS DRI\rE adds

low-end

frequencies to the

sound you will hear as you tum up this control. Remember, these three

controls work as

partners,

not

individually.

Once

you

have

the setting

like,

.you

can tum up the

to

control volume.

This

SONIC CIRC[JIT

nothing to do with

will hear

that this

a three-wire line with a

lt

is not a

idea to

rernoye the

under any circumstances. lf

it

is

necessary

to

operate the amp

with the old 2

prong plugs,

a suitable

adapter sfrould

be used.

Operating

amp with the

proper grounding

receptacle reduces

hazard of sftock.
