HUM

AND

NOISE

In

any

high

fidelity

installation,

hum

may

be

caused

by

the

interconnection

of

a

turntable,

tuner

and

amplifier,

and

speakers

as

the

result

of

wiring,

different

grounding

or

locations

of

components

If

hum

is

experienced

with

your

unit,

disconnect

everything

but

the

speakers

from

the

unit.

Plug

in

the

turntable

and

if

hum

or

howling

appears,

move

the

turntable

away

from

the

speakers

as

much

as

possible.

Note

hum

may

also

be

induced

by

defective

cable

connec¬

tions

or

by

running

the

cables

too

close

to

strong

Ac

field.

When

your

unit

picks

up

noise

during

the

reception

of

broad-casts,

causes

are

mostly

due

to

external

objects

such

as

fluorescent

lamps

and

house

appliances

using

motor

or

thermostat,

or

others

that

may

induce

the

noise.

Either

relocating

the

unit

away

from

the

noise

sources

or

using

an

improved

outdoor

antenna

may

readily

solve

the

problem.

In

the

event

you

cannot

find

the

cause

consult

your

dealer

or

a

qualified

electrician.
