• Locations exposed to direct sunlight
• Places subject to humidity and with less ventilation
• Places where are extremely hot or cold
• Places subject to strong vibration
• Places subject to dust
• Places subject to oil, steam, and heat (such as kitchens)
To avoid heat emission
Do not place this unit on such device as an amplifier that may
emit heat. If the unit is installed on a rack, install the unit as
distantly as possible from where the amplifier is installed so
as to avoid heat emission from the amplifier and other audio
devices.
Power off this unit when it is not used.
Depending on the condition of radio waves emitted during
television broadcasting, interference fringes may appear on
the television monitor, but that is not a malfunction. In such
a case, power off the unit. There may also be a case where
noises are heard on the radio due to radio wave interference.
Notice when handling optical digital cables
• Do not fold the cables. For storage, wind each cable to
make a coil whose diameter is approx.15 cm or larger.
• For connection, insert the cable connectors firmly into the
terminals of this unit and the other device.
• Use the cables whose each length is 3 m or less.
• When the cable connectors get dusty, wipe the dust away
with a dry soft cloth before inserting into the terminals.
Cleaning
• Usually, wipe the unit with a dry soft cloth. When the dirt
is hard to remove, dip soft cloth in detergent diluted 5 or 6
times with water, wring it well, and remove contaminants.
Then, remove the moisture with dry cloth.
• Do not use a solvent like alcohol, benzine, thinner, or pes-
ticide because such a substance can damage the exterior.
In addition, do not let this unit contact a rubber or plastic
form for a long time. That may damage the cabinet surface
of the unit.
• When using a chemical cloth for cleaning, read the caution
provided with the chemical cloth product.
• Before cleaning, unplug the power cord from the AC outlet.

minals are not output from the analog balance output termi-
nals (XLR) or digital output terminals (OPT/COAX).
10. Analog unbalance output terminals
(RCA)
These are RCA output terminals used for the unbalanced
playback output signals from this unit.
When the line output level fix/variable selection switch (FIX/
VARIABLE) is set to VARIABLE, the output level varies de-
pending on the state of the volume control (VOLUME) on
the front panel.
11. Line output level fix/variable selection
switch (FIX/VARIABLE)
Toggles the level of the playback signals from the analog
unbalance output terminal (RCA) between fixed and vari-
able.
When this switch is set to FIX, the line output level fix indica-
tor (FIX LINE-OUT) lights up to indicate that the output level
from the analog unbalance output terminal (RCA) is fixed
and cannot be adjusted with the volume control.
When the switch is set to VARIABLE, the output level of
volume control on the front panel and that of the analog
unbalance output terminal (RCA) changes interlockingly.
(The sound volume of the headphone can be adjusted re-
gardless of the state of the selection switch.)
Besides, the level of the playback signals from the analog
balance output terminals (XLR) is always fixed regardless of
the state of the selection switch.
When the selection switch is toggled, the line output level
may greatly change.
Be careful of the sudden change in the sound volume.
