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.
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.
15. Batteries shall not be exposed to excessive heat such as sunshine, fire or the like.
CAUTION:
• To completely disconnect this product from the mains, disconnect the plug from the wall socket outlet.
The mains plug is used to completely interrupt the power supply to the unit and must be within easy access by
the user.

①Power Switch (Power)
Press the “Power” switch to turn the a210 on, and press
again to turn off. The sound will not be output for four
seconds after the a210 is turned on.
②Input Selector Switch (Selector)
Select input source (INPUT) that is connected at the
back of the a210.
③Volume Knob (Volume)
Adjust the audio volume. Audio level will increase by
turning the Volume clockwise.
④Headphone Output (Phones)
Insert headphones here. Sound will not be output to
the speakers when headphones are inserted. Adjust
headphone volume by turning the volume knob.
Note:
In the interest of sound quality, the headphone
output circuit has been designed without the use
of a series resistor. Therefore, the right and left
channels may be shorted when the headphone plug
is inserted halfway, resulting in sound dropouts.
When using headphones, make sure the head-
phone plug is inserted completely. Audio volume
should be minimized when the headphone plug is
inserted or removed.

This function will be ignored and audio gain will be
fixed as “L” when Headphones are connected.
cSpeaker Terminal (SPEAKER)
These terminals are used for connecting speakers. The
impedance of the speaker must be 8 ohms or more.
Note:
Do not connect equipment other than speakers to
these terminals. Please keep as much distance as
possible between speaker cables and input cables.

Connecting Speakers
• The impedance of the connected Speaker System
must be 8 ohms or more. If the connected speaker
has an impedance of less than 8 ohms, audio may
be distorted or the protection circuit may trigger to
prevent damage to the system.
• Always match polarity when connecting the amplifier
to the speaker system (Plus ( ): Red and Minus ( ):
Black).

This equipment adopts the European Type of XLR
connector. If the connecting equipment has the “USA
Type” of XLR then the audio signal becomes reverse
phase. In this case, swap pin 2 and pin 3 of XLR
connector (INPUT or OUTPUT) to work the same as the
European Type.
