ANTENNA
CONNECTION
The
quality
of
reception
that
can
be
expected
from
the
TU-666
depends
largely
on
the
correct
position-
ing
and
use
of
antennas.
To
pull
in
more
stations
more
clearly,
the
following
procedures
are
recom-
mended:
Built-in
AM
Ferrite
Antenna
This
highly
sensitive
antenna,
located
on
the
rear
panel
of
the
tuner,
is
usually
adequate
for
AM
reception
in
many
areas.
To
use,
pull
it
down
and
away
from
the
back
of
the
tuner
until
the
best
reception
is
obtained.
Outdoor
AM
Antenna
In
ferroconcrete
buildings
or
in
fringe
areas,
the
built-in
ferrite
antenna
may
be
inadequate
for
reception
of
weak
or
distant
stations.
An
outdoor
antenna
then
becomes
necessary.
This
can
be
accomplished
by
connecting
the
PVC
wire
supplied
with
the
set
to
the
antenna
terminal
marked
AM-
A
on
the
rear
panel.
Run
this
wire
to
an
antenna
that
has
been
placed
outside
a
window
or
mounted
on
a
roof.
At
the
same
time,
the
unit
should
be
grounded.
Position
the
outdoor
antenna
where
reception
is
strongest
while
actually
receiving
a
broadcast.
And,
for
reasons
of
safety,
be
sure
to
attach
a
lightning
arrester
to
the
outdoor
antenna.
Indoor
FM
Antenna
In
urban
or
strong
signal
areas,
satisfactory
FM
reception
can
be
obtained
by
using
the
folded
dipole
antenna
(300
ohm)
supplied
with
the
TU-666.
Connect
the
two
leads
from
the
dipole
to
the
ter-
minals
marked
FM
300Q
Al
and
A2
on
the
rear
panel
and
tack
the
dipole
up
on
the
wall
in
the
form
a
T.
Be
sure
to
position
the
dipole
for
best
signal
reception
before
the
antenna
is
permanently
tacked
up
on
the
wall.
Outdoor
FM
Antennas
In
ferroconcrete
buildings
or
in
fringe
areas,
the
indoor
dipole
antenna
may
be
inadequate
for
recep-
tion
of
weak
or
distant
FM
stations.
An
outdoor
antenna
designed
specifically
for
FM
should
then
be
installed.
Either
a
balanced
300
ohm
or
unbalanced
75
ohm
antenna
can
be
used
with
the
TU-666.
If
the
300
ohm
twin-lead
is
used,
connect
it
to
the
terminals
marked
FM
3009
A,
and
A,
on
the
rear
panel
just like the indoor dipole antenna connection. If
the 75 ohm coaxial cable is used, connect the center
conductor to the FM 759 A terminal and the
shielding wire to the G terminal.
Note: FM sensitivity cannot be raised simply by
lengthening the antenna. Adjust the antenna’s
height and direction while actually listening to a
broadcast for best reception.
AMPLIFIER CONNECTION
To connect a control amplifier to the TU-666, use
the two cables supplied with the tuner. Connect
the R output on the rear panel of the tuner to the
right channel input marked TUNER or AUX on
the rear of the amplifier. The left channel connec-
tion are made between the L output of the tuner
and the left TUNER or AUX input of the
amplifier.
OPERATIONS
To Listen to an AM Program
1. Set the SELECTOR switch to the AM position.
2. Select your desired station on the AM band of
the tuning dial with the TUNING knob. The
station is properly tuned when the needle in the
tuning meter swings to the maximum upward
position.
Note: While the scale of the tuning meter is gra-
duated from 1 to 5, the needle need not move all
the way to “5” to indicate optimum reception.
To Listen to an FM Program
1. Set the SELECTOR switch to the FMA AUTO
position. If too much noise or interference accom-
panies a stereo program with the SELECTOR
switch in the FM AUTO position, turn it to the
FM MONO position and listen to the program
monophonically.
2. Set the MUTING switch to the ON position.
3. Select your desired position on the FM band of
the tuning dial with the TUNING knob, The ©
station is properly tuned when the needle in the
tuning meter swings to the maximum upward |
position.
4, Set the NOISE CANCELER to the ON position
if annoying noise accompanies the FM stereo
program.
5. For FM stereo reception, the mode switch of
the control amplifier must be in the STEREO
position.
