IMPORTANT SAFETY INSTRUCTIONS
• Explanation of Graphical Symbols
12 Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury from tip-over.
13 Unplug this apparatus during lightning storms or when unused for long periods of
time.
14 Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
We Want You Listening For A Lifetime
We group want you to get the most out of your equipment by playing it at a safe
level. One that lets the sound come through loud and clear without annoying
blaring or distortion –and, most importantly, without affecting your sensitive
hearing.
Since hearing damage from loud sounds is often undetectable until it is too late,
We recommend you to avoid prolonged exposure from excessive volume levels.
The lightning flash with arrowhead symbol, within an equilateral triangle, is
intended to alert you to the presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient magnitude to constitute a risk
of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert you to
the presence of important operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
1 Read these instructions.
2 Keep these instructions.
3 Heed all warnings.
4 Follow all instructions.
5 Do not use this apparatus near water.
6 Clean only with dry cloth.
7 Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8 Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9 Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has
two blades with one wider than the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10 Protect the power cord from being walked on or pinched particularly at plugs, convenience
Receptacles, and the point where they exit from the apparatus.
11 Only use attachments/accessories specified by the manufacturer.

Connecting speakers
・Connection method A (Recommendation)
Insert a 4 mm banana clip (not included) to the end of the cable
and insert it into the speaker terminal hole of this instrument.
Attention How to connect speakers
・This unit is compatible with speakers that have 4–8Ω nominal
impedance. If speakers with impedance of less than 4 Ω are used,
the protection circuit could operate, causing sound output to
stop. In some cases, this unit or the speakers could be damaged.
・The red speaker terminals are positive (+) and the black speaker
terminals are negative (-). Generally, the (+) wire of the speaker
cable is marked to distinguish it from the (-) wire of the cable.
Connect the marked wire to the red (+) terminal and the
unmarked wire to the black (-) terminal.
・If the exposed core wires at the tips of the speaker cables
should touch other cables or terminals, an electrical short might
occur.
・Never allow speaker cables to cause a short.
・To prevent hum and noise, avoid bundling the cables together
with the AC power cord or other cables.
・Connection method B
Remove about one centimeter of insulation from the end of the
speaker cable and twist the core wires well.
Turn the terminal cap counterclockwise to loosen it.
Insert the wire into the hole in the terminal post and turn the
terminal cap clockwise to securely connect it.

Connecting headphone
◆CAUTION
While wearing headphones, do not connect or disconnect them,
turn the unit on or off, or switch the headphone amp gain.
Doing so could result in a sudden loud noise that could harm your
hearing.
Always set the amplifier volume to minimum before connecting
and unconnecting headphones on. (Left rotating end is minimum
volume)
To prevent hearing loss, do not raise the volume level excessively
when using headphones.
PHONES jack
This headphone amp circuit uses a three-pole connector with
Common left and right for grounding. Ordinary 3.5mm stereo
mini plugs with 3 poles can be used.
Left rotating end is minimum volume

Connecting to a network (PC/NAS/Internet connection)
CAUTION
•For details on Internet connection, refer to the owner’s manuals
of your network devices.
•If you are using a router that supports DHCP, you do not need to
configure any network settings for the unit.
•Wired connections are recommended for devices other than the
mobile to ensure high sound quality.
•Some security software installed on your PC or the firewall
settings of network devices (such as a router) may block the
access of the unit to the network devices or the Internet. In this
case, change the setting of the security software or network
devices.
•When setting the subnet manually, each server must be
connected to the same subnet as the unit .wearing headphones,
do not connect or disconnect them, turn the unit on or off, or
switch the headphone amp gain. Doing so could result in a
sudden loud noise that could harm your hearing. Always set the
amplifier volume to minimum before connecting and un
connecting headphones on. (Left rotating end is minimum
volume) To prevent hearing loss, do not raise the volume level
excessively when using headphones.
Connecting to a network
(PC/NAS/Internet connection)
You can play back music files stored on your PC or NAS, audio
contents on the Internet radio, by connecting this unit to
a network.
Connect with a commercially available STP (shielded twisted pair)
network cable (CAT-5 or higher, straight-through)
