source
may
cause damage
to
this
unit and/or
severe
electrical
shock.
DO NOT
PLUG IN OR UNPLUG
THE POWEB
CORD WITH WET HANDS
There
is a
great
danger of severe electrical shock if
the
power
cord is
plugged
in
or unplugged with wet

request
service from
your
authorized service dealer. Continued
use under
these
conditions,
may
cause
f
ire or electrical shock.
DO

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
lt in
a
well
ventilated area
for
proper
heat
dissipation.
Avoid
placement
in direct sunlight,
near
air conditioners,
poorly
ventilated areas or
in
areas of excess humidi-
ty or dust. Do not
block the
ventilatlon holes.
3. CONNECTTONS
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
CORRECT CONNECTIONS
lf
you
reverse
the
R
(right)
and L
(left)
leads,
you
will reverse
the stereo location
of R
and L channels.
MAKE
CONN
ECTIONS
SECUR ELY
lf
any of
the
plugs
should
become loose or
connected, a
hum may
develop. lf
this is
corrected, deterioration of
sound
quality
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.
WHEN NOT
USING THE PHONO INPUTS,
KEEP
THE SHORTING PLUGS
INSERTED IN THE
INPUTS
This
is
to
prevent
hum
and
noise
and
to
prevent
the
popping
noise which
can occur when
switching
the
proqram
selector
switch
without
a

connected.
WHEN
USING THE
COMPANION POWEB
AMPLIFIER
(DA-A1ODC,
DA.A1sDC)
AND
SWITCHING TWO PAIRS
OF SPEAKERS FROM
THIS
UNIT,
ENSURE
THAT THE
COMBINED
IMPEDANCE
(BOTH
PAIRS OF
SPEAKERS
OPERATING)
IS 4
OHMS OR ABOVE
lf the combined impedance
is
below 4
ohms, the
load
impedance
detector circuit may
operate and
mute
the
power
amplif
ier output.
d is-
not
and
The
combined impedance is determined with
the
following formula.
