Wire Connections
When
connecting tape decks, record players or
other
components to
the
350A, be
sure
to
use shielded
wire.
The
use of
an
ordinary cord or vinyl wire
may cause
humming
and buzzing.
The
length of
the
shielded wire used should be sho
rter
than
5 feet.
Be sure
that
all lead wires between the amplifier
and components are properly connected.
If
the
con-
nections are loose or in touch
with
other
parts, the
amplifier will not function properly, may pick up
noise, and ev
en
breakdown over a period of time.
Also
be
sure to read the
manufacturer
's instructions
for any component before connecting it to
the
350A.
The
shielded
wire
is
made
up for use as illustrated
below:
Local-Distant
Antenna
Switch
This
switch adjusts
the
tuner
to
the
strength
of
FM
radio waves.
It
should be set to
DIST
if the receiver
is
located in an
area
where
FM
signals are weak,
or to LOC if it
is
located
near
broadcasting
stations
and there
is
danger
of interstation interference.
Humming
and
Howling
Care
must be taken
never
to place a record player
on
or
too
near
a
speaker
enclosure. Otherwise
the
vibration of
the
speaker
enclosure
is
transmitted
to the player and causes howling.
It
is
best to keep
these components completely separated,
but
if this
is
impossible, to place a thick cushion between them.
Humming
is
a phenomenon caused by incomplete
or incorrect player-amplifier connection.
If
this
occurs, check to make
sure
that
all connections
are
complete and
that
the thickness of the connecting
wire is sufficient.
Be
sure
to connect the ground-
ing lead (
or
terminal) of the record player to
the
GND
terminal of the 350A.
It
ma
y suppress the
hum
noise which may otherwise occur.
