CAUTION: Describes precautions that should be observed to prevent danger of the apparatus.
IMPORTANT SAFETY INSTRUCTIONS
·Read these instructions.
·Keep these instructions.
·Heed all warning.
·Follow all instructions.
·Water & Moisture
The apparatus should be protected from moisture and
rain, can not used near water, for example: near bathtub, kitchen sink or a swimming pool, etc.
·Heat
The apparatus should be located away from the heat
source such as radiators, stoves or other appliances
that produce heat.
·Ventilation
Do not block areas of ventilation opening. Failure to
do could result in fire. Always install accordance with
the manufacturer's instructions.
·Object and Liquid Entry
Objects do not fall into and liquids are not spilled into
the inside of the apparatus for safety.
·Power Cord and Plug
Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus.
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 is provided for your safety.
If the provided plug does not fit into your outlet, refer to
electrician for replacement.
28
·Power Supply
The apparatus should be connected to the power supply
only of the type as marked on the apparatus or described
in the manual. Failure to do could result in damage to the
product and possibly the user.
Unplug this apparatus during lightning storms or when
unused for long periods of time.
·Fuse
To prevent the risk of fire and damaging the unit, please
use only of the recommended fuse type as described in
the manual. Before replacing the fuse, make sure the unit
turned off and disconnected from the AC outlet.
·Electrical Connection
Improper electrical wiring may invalidate the product warranty.
·Cleaning
Clean only with a dry cloth. Do not use any solvents such
as benzol or alcohol.
·Servicing
Do not implement any servicing other than those means
described in the manual. Refer all servicing to qualified
service personnel only.
·Only use accessories/attachments or parts recommended
by the manufacturer.
·Warning
Please remember the high sound pressure do not only
temporarily damage your sense of hearing, but can also
cause permanent damage. Be careful to select a suitable
volume.

14. FUSE holder
The fuse holder is for containing the fuse, which is a safety device that protects the AC supplies circuit of the unit.
Caution: if the fuse blew out, it should be replaced with the same type and specification, if the fuse continues to
blow out, please stop using and refer servicing to qualified personnel.
15. AC power socket
It is used to connect the power supply to the unit via enclosed power cord.
Caution: ensure the source voltage matches the voltage of product before turning on the unit.
16. Voltage selection switch
This switch provides two voltage selections: 115V or 230V, please select the proper voltage depends on actual
application.

3-band equalization to modify the sound tone. These controls are electronically post-gain and if boosted can clip

ON: the signal ground is electrically disconnected from the amplifier ground circuit (the chassis). If hum is heard in
the loudspeakers, the ON position breaks the ground loop, often the cause of this interference.
OFF: the ground of the input signals is electrically connected to the amplifier ground circuit (the chassis).
USE GROUND LIFT ONLY WITH BALANCED SIGNALS.
