PRECAUTIONS
1. GENERAL
BE
SURE
TO
USE
YOUR
A.C.
POWER
SOURCE
Your
A.C.
power
is marked
on
the
rear
panel
of
this
unit.
Connection
to
any
other
power
source
may
cause
damage
to
this
unit
and/or
severe
electrical
shock.
DO NOT PLUG IN OR UNPLUG THE POWER
CORD WITH WET HANDS
There is a great danger of severe electrical shock if
the power cord is plugged in or unplugged with wet
hands.
Do
not
attempt
to
unplug
the
cord
from
an
A.C.
outlet
by
pulling
the
cord.
Firmly
grasp
the
plug to remove it from the A.C. outlet.
DO NOT ALLOW WATER OR ANY FOREIGN
MATTER TO GET INSIDE THIS UNIT
Should water or a metailic object accidentally fall
into this unit, immediately disconnect the power
cord and consult your authorized service dealer.
HANDLE THE POWER CORD WITH CARE
Do
not
bend
sharply
or
twist
the
power
cord.
If
the
insulation
becomes
damaged,
the
conductor
breaks,
or poor contacts occur, request service from your
authorized
service
dealer.
Continued
use
under
these
conditions, may cause fire or electrical shoek.
DO NOT TOUCH THE INSIDE OF THIS UNIT
There
are
high
voltages
inside
this
unit.
Never
re-
move
the
top
or
bottom
cover.
All
inspections
and
repair
including
fuse
replacement,
should
be
carried
out by your authorized service dealer.
DISCONNECT
THE
POWER
CORD
AT
THE
FIRST
SIGN
OF
TROUBLE
At the first sign of unusual noise, odor, or malfunc-
tion, disconnect the power cord and consult your
authorized
service
dealer.
Continued
use
under
these
conditions, may increase damage or cause additional
problems.
2. LOCATION
AVOID PLACEMENT IN DIRECT SUNLIGHT,
NEAR AIR CONDITIONER ETC.
This unit can become unstable if operated in ex-
tremely high or low temperatures. Place it in a well
ventilated area for proper heat dissipation. Avoid
placement in direct sunlight, near air corditioners,
poorly ventilated areas or in areas of excess humidi-
ty or dust. Do not block the ventilation holes.
3. CONNECTIONS
BE SURE TO TURN OFF THE POWER BEFORE
MAKING CONNECTIONS
This
is
to
prevent
damage
to
the
speakers
from
the
popping
noise
which
occurs
when
plugging
and
unplugging
cords.
USE
EXTREME
CARE
IN
MAKING
THE
COR-
RECT CONNECTIONS
If
you
reverse
the
R
(right)
and
L
(left)
leads,
you
will
reverse
the
stereo
location
of
R
and
L
channels.
MAKE CONNECTIONS SECURELY
If
any
of
the
plugs
should
become
loose
or
discon-
nected,
a
hum
may
develop.
If
this
is
not
corrected,
deterioration
of
sound
quality
and
possible
damage
to
the
speakers
may
result.
USE
ONLY
SHIELDED
CORD
FOR
THE
LEADS
Use
only
shielded
cords
for
interconnecting
com-
ponents.
Do
not
use
cords
longer
than
2m
(6'),
Ex-
cessive
lead
lengths
can
deteriorate
high
frequency
response
and
are
subject
to
interference
that
can
result
in
hum
or
noise.
DO
NOT
SHORT
THE
OUTPUT
OF
THE
POWER
AMPLIFIER
This
unit
incorporates
a
protection
circuit
so
that
power
transistors
will
be
protected
in
case
of
a
short.
Shorts
can
reduce
the
life
of
the
transistors
and
should
be
avoided.
USE
SPEAKERS
WITH
NOMINAL
IMPEDANCE
OF
4-16
OHMS
If
you
use
speakers
with
a
load
impedance
of
less
than
4
ohms,
the
protection
circuit
may
be
triggered
and
the
amplifier
output
muted.
WHEN
CONTROLLING
TWO
PAIRS
OF
SPEAK-
ERS
SELECTION
FROM
THE
COMPANION
PREAMPLIFIER,
ENSURE
THAT
THE
COM.-
BINED
IMPEDANCE
(BOTH
PAIRS
OF
SPEAK-
ERS
OPERATING)
IS
4
OHMS
OR
ABOVE
If
the
combined
impedance
is
below
4
ohms,
the
load
impedance
detector
circuit
may
operate
and
mute
the
power
amplifier
output.
The
combined
impedance
is
determined
with
the
following
formula.
Ax
COMBINED
IMPEDANCE
