Connecting
a Speaker System
Speakers with nominal impedance of 4 to 16 ohms
may be hooked to this amplifier. Avoid usmg
speakers with impedance below 4 ohms.
To
connect a stereo speaker sy
stem
:
1. Connect the (
+)
terminal of the spea
ker
on y
our
left (as viewed from the listening area) to
the
red
terminal
marked
(+ )
LEFT
SYSTEM
A on the
rear
panel of the amplifier.
2. Connect the (- ) or common terminal of the left
speaker
to the black terminal
marked
(- )
LEFT
SYSTEM
A.
3. Connect the (+ ) terminal of the
right
speaker

To
connect to the terminals of
the
amplifier:
1. Depress
the
colored button, opening a hole m
the terminal.
2. Push the stripped end of lead wire m the hole
and release the button.
When
you intend to connect two sets of stereo
speaker
systems to this amplifier, be
sure
to use
speakers having impedance of 8 ohms or more.
If
you
are
using only one speaker, connect the
speaker leads to either
right
or left channel termi-
nals of
SYSTEM
A or
B.
If
Speaker Polarities Are
Not
Properly Matched
...
If
the
polarities (+ and - ) of the !>peakers and the
amplifier are not matched correctly, sound cancella-
tion
at
some frequencies or in some listening posi-
tion occurs. Particularly
when
listening to mona
u-
ral reproduction, this condition
is
noticeable by an
absence of sound
at
a point midway between
right
and left speakers. If this situation occurs, check
the
amplifier
and
spea
ker
connections once again
and reverse the connections between
the
amplifier
and
either
right or left speaker.
Connecting
a Record Player
The
following procedures are recommended for use
with a player or turntable utilizing a magnetic car-
tridge
with
an output voltage between 2mV and
lOmV.
1.
Connect
the
left channel output of a stereo turn-
table to the
LEFT
channel (upper)

ANTENNA
CONNECTION
-
RADIO
RECEPTION
The
quality of reception
that
can be expected from
the 350A
is
largely dependent on the correct posi-
tioning and use of antennas.
The
following proce-
dures are recommended for noise-free reception.
FM
Antenna
Where
FM
broadcasting stations are near and
FM
signals are strong, satisfactory
FM
reception can be
obtained by using the feeder wire accompanying
the amplifier. Connect the feeder wire to the an-
tenna terminals marked
FM
300,0,-Al and A2 on
the rear panel, then fully extend
the
wire to a T
form and
fix
it to a wall or ceiling
where
it allows
the strongest reception.
If
the 350A
is
used in a thick-walled building or
in
an area remote from
FM
broadcasting stations, the
indoor feeder wire antenna may be inadequate for
strong signal reception.
An
outdoor antenna de-
signed exclusively for
FM
reception should then be
installed.
FM
antennas for the 300-ohm balanced type and
75-ohm unbalanced type can be used with the
350A. Connect either
antenna
to the matching
antenna terminals on the rear of the amplifier.
The
300-ohm feeder wire should be connected to the
antenna terminal marked
FM
300,0,-Al and A2.
If
the 75-ohm coaxial cable
is
used, connect the con-
ductor to
the
antenna terminal
marked
FM
75,0, -
Al,
and the shielding wire to the terminal
G.
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 the best reception.
Built-in
AM
Ferrite Bar
Antenna
This
sensitive antenna, located on
the
rear
panel of
the
amplifier,
is
usually adequate for
AM
reception.
To
use, pull it down and away from the back of
the amplifier until it comes to a stop halfway between
the top and the bottom of the amplifier.
Then
move it from up to down until best reception
is
obtained.
- 9
Outdoor
AM
Antenna
In ferroconcrete buildings or in areas remote from
the broadcasting station, the built-in ferrite bar
antenna may be inadequate for
AM
reception.
An
outdoor antenna then becomes necessary.
This
can
be accomplished by connecting the
PVC
wire ac-
companying
the
amplifier to the antenna terminal
marked
AM-Al
on the back panel. Run this wire
to an antenna
that
has been installed outdoors and
away from the building.
At
the
same time, the unit.
should be grounded. Adjust the outdoor antenna for
maximum signal pick-up, while actually receiv
in
g
a broadcast. And, for reasons of safety, be sure to
attach a lightning arrester to the outdoor antenna.

How
to
Eliminate Radio
Noise
AM
Reception
AM reception noise can often be eliminated by
changing the position of the antenna.
If
you are
located far from the broadcasting station, or in the
mountains, a thick-walled building or a block of
such buildings, radio waves will not be well received,
resulting in unstable reception and increased noise.
If
reception
is
poor, connect a vinyl wire (supplied)
to the
AM
antenna terminal and position it for best
reception.
If
this does not reduce noise or improve
sensitivity, erect an antenna outside the building
and
apart
from the wall. Some noises are peculiar
to a certain broadcasting frequency or a certain time
of day.
These
result from the
nature
of
AM
signals.
In
some cases the noise can be eliminated by ground-
ing
the
amplifier or reversing the power-cord plug
receptacle connections.
FM Reception
Noise during
FM
reception can be generally attrib-
uted to either insufficient antenna input or interfer-
ence from other electrical appliances.
Antenna
input is insufficient when the antenna
is
not
installed properly or when the station
is
far away.
Extend
and
fix
the attached antenna so
that
noise
is
minimized and the antenna input
is
at
maximum.
For
better
results, install an exclusive
FM
antenna
in a position to receive signals most effectively.
If
you use a
T.V.
antenna for both
T.V.
set and
FM
unit with a splitter, make sure
that
the televi-
sion reception
is
not affected.
To
prevent noise,
avoid using a long antenna wire.
FM
reception
is
affected considerably by the trans-
mitting conditions of certain stations: usually their
power and antenna efficiency. You may receive one
station quite well and another poorly.
Noise Common to FM and
AM
In an area with many ferroconcrete buildings, noise
may occur at a particular time of day.
This
noise
is
easily distinguished from
that
discribed above.
To
eliminate such noise, attach a noise arrester to
the
interfering electrical appliances or to the power
source of the 350A.
When
you are listening to an
FM-MPX program, you may notice a noise not heard
with monophonic
FM
broadcasts.
In
some cases,
you can also eliminate
the
noise by setting the
TREBLE
control to "flat" or lower.

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.

Quick-Acting Fuses
These
fuses for right and left channels are also de-
signed to protect the transistors by blowing instantly
if
shorting occurs between connections at a speaker
system terminal.
If
, after the
POWER
switch
is
turned on and the dial scales
li
ght up, neit
her
channel operates or only one operates normall
y,
is
either
because one or both Quick-Acting fuses have
blown.
In
this case, remove the 3
50A
's power
supply cord from its outlet, remove the wood case
from the chassis, and check to see if the fuses are
blown. Replace them with identical 2.
5A
fuses a
ft
er
finding and eliminating the source of trouble that
caused them to blow.
AC
Outlet
The
350A
is
provided with an
AC
outl
et
on the back
pane
l.
It
is
controlled by the
POWER
switch
on
the front panel.
CAUTION:
The maximum capacity of this outlet
is
50VA. ever use it beyond its rated capacity.
The voltage supplied by the
AC outlet
is
the same as the
po
wer
supply voltage used.
Power
Fuse
Should the ampli
fi
er
fa
il
to operate and the
di
al
scales
fa
il
to light up when the
POWER
switch
is
turned
on
, the probable cause
is
either a power
stoppage or a blown fuse.
To
check, remove the
350A s power supply cord from its outlet, turn the
fuse holder on the
rear
panel counterclockwise, and
remove the
fu
s
e.
If it
is
blown, replace it with a
new glass-tubed fuse of the same capacity (

A,

0-----
250V-1.5A) after
de
termining
and eliminating the trouble source that caused the
fu
se to blow. Using wire or a fuse of a different
capacity as a stop-gap measure is dangerous and
should be avoide
d.
DIN
Socket
If
your tape deck has a
Dl
socket, it may be
connected to the 350A simply by the use of a cable
with a 5-pin DIN connector on each end. Insert
each connector to the DI socket
on
the receiver's
r
ear
panel and into the
on
e on the tape deck.
The
DI connection system, designed to simplify inter-
connections between the tape deck and amplifier,
is
based
on
the German DIN
Standard
s.

Grounding
Connect one end of vinyl or enameled wire
to
the
terminal screw marked
GND
at the
rear
of the am-
plifier, attach a copper plate to the
other
end, and
bury it underground.
Whenever
an outdoor
AM
antenna
is
used, grounding becomes necessary.
In
all cases,
gr
ounding
is
desireable since it allows a
better S ratio to
be
obtained.
To
ground an en-
tire audio system, connect the grounding wire of
each component used to this terminal.
Voltage
Adjustment
To
reach the Voltage Selector remove the two
screws from the nameplate on the rear panel and
then remove the nameplate.
The
Voltage Selector
makes
it
possible to operate the 350A at the correct
voltage in any
area
.
The
voltage has been pre-adjusted at the factory,
but can
be
easily readjusted as follows:
STEP
I Set arrow
of
main Voltage Selector plug
to required voltage: 100,
ll0,
ll7,
127, 220, 230,
240 or 250 volts.
STEP
II
If
numerals
of
voltage are printed in red,
set arrow of adjacent sub V.S. plug to position
marked red.
If
they are printed in white, set arrow
to position marked white.
STEP
III
The
power fuse should also be changed
when the AC line voltage
is
changed
For
100......,127
volt operation a 2-ampere fuse
is
required. For
220......,250
volt operation the fuse should be changed
to a 1.5 ampere unit.
NOTE:
The
Voltage Selector can be used to elimi-
nate
the trouble caused by the considerable voltage
fluctuation. In this case, it should be set to the peak
voltage.
