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
the
red
terminal
marked
( + )
RIGHT
SYSTEM
A.
4.
Connect the ( - ) or common terminal of
the
right
speaker
to the black terminal marked ( - )
RIGHT
SYSTEM
A.
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 2m V and
lOmV.
1.
Connect
the
left channel output of a stereo turn-
table to the
LEFT
channel (upper)
PHO
O input
jack on the
rear
panel of the amplifier.
2. Connect
the
right channel output of the turn-
table to the
RIGHT
channel (lower)
PHO
O input
jac
k.
3. If a monophonic player or turntable
is
used, it
may be connected to either
RIGHT
or
LFFT
chan-
nel
PHONO
input jack.
NO
TE:
Although it is not recommended from a
standpoint of tone quality, if a player with a crystal
cartridge must be used, connect
the
o
utput
of
th
e
player to an input jack labeled
AUX
on the
rear
of
the amplifier.
To
Listen
to
Records
1.
Set
the
SELECTOR
switch to the
PHONO
posi-
tion.
2. Set the
MODE
switch to
either
STEREO
or
MONO
, depending on the type of record player
used.
3. Switch on
the
record player and adjust its speed
of rotation (
RPM
) for
the
record to be played. (33
½, 45 etc.)
4.
After
placing
the
needle on
the
record, adjust
the BA
LANCE
control for equal sound from both
right
and
left channels.
5. Use
other
controls and switches according to
y
our
taste
and
listening conditions.
NOTE:
When
playing monophonic records on a
stereo record player, follow
the
same procedures as
for stereo records for best results.
To
balance the
sound from b~th channels, play a monophonic
record the
same
as a stereo record and adjust the
BALANCE
control so
that
the sound
is
heard
from
a point midway between the
right
and left speakers.
