PRECAUTIONS
1.GENERAL
BE SURE TO USE YOUR A.C. POWER SOURCE
Your A.C. power requirement is marked on the
side 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
AC. outlet by pulling the cord, Firmly grasp the
plug to remove it from the AC. outlet.
DO NOT ALLOW WATER OR ANY FOREIGN
MATTER TO GET INSIDE THIS UNIT
Should water or a metallic 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 shock.
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 mal-
function, 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 exA
tremely high or low temperatures. Place it 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 ventilation holes.
3. CONNECTIONS
PLUG THE POWER CORD OF THE POWER
AMPLIFIER INTO THE SWITCHED" A.C.
OUTLET OF THIS UNIT.
This is to prevent popping noise when the power
to this unit is switched on or off.
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
CORRECT CONNECTIONS
If you reverse the R (right) and L (left) leads, you
will reverse the stereo location of R and L channels.
IN MAKING THE
MAKE CONNECTIONS SECURELY
If any of the plugs should become loose or dis-
connected, 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.
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
program selector switch without a turntable
connected.
WHEN USING THE COMPANION POWER
AMPLIFIER (DA-A7DC, DA-AIODC, DA-A15DC)
AND SWITCHING TWO PAIRS OF SPEAKERS
FROM THIS UNIT, ENSURE THAT THE COM-
BINED IMPEDANCE (BOTH PAIRS OF SPEAK~
ERS OPERATING) IS4 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.
A
COMBINED IMPEDANCE = A:
B IOHMSI
B
