IMPORTANT SAFETY PRECAUTIONS
CAUTION: TO REDUCE THE RISK OF ELE CTRIC SH OCK, DO NOT REMOVE
COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within equilateral triangle, is intended to
alert the user 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 the user to
the presence of important operating and maintenance (servicing) instructions in the
literature accompanying the appliance.

WARNING: TO PREVENT FIRE OR SHOCK
APPLIANCE TO RAIN OR MOISTURE.
For U.S.A.
TO THE USER
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed
to p ro vid e rea son abl e pro tec tion again st ha rmf ul
interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to
radio communications.
However, there is no guarantee that interference will
not occur in a particular installation. If this equipment
does cause harmful interference to radio or television
reception, whic h can be determin ed by turning the
equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following
measures.
a) Reorient or relocate the receiving antenna.
b) Increase the separation between the equipment and
receiver.
c) Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
d) Consult t he dea ler or an e xperi en ced radio/ TV
technician for help.
HAZARD, DO NOT EXPOSE THIS
CAUTION
Cha nges o r mo dif i cat ions t o th is equip men t not
expressly approved by BMB Corp. for compliance could

replacement of the obsolete outlet.
• Do not expose this apparatus to drips or splashes.
• Do not place any objects filled with liquids, such as
vases, on the apparatus.
• Do not install this apparatus in a confined space
such as a book case or similar unit.
• The apparatus draws nominal non-operating power
from the AC outlet with its POWER switch in the off
position.
• The apparatus should be located close enough to
the AC outlet so that you can easily grasp the power
cord plug at any time.
• An app a r a t u s w i t h Class I constructio n shall
be connected to an AC outlet wit h a prote cti ve
grounding connection.
10
Protect the power c ord fro m bei ng w alked o n
or p inc hed p art icu lar ly at p lug s, con ven ien ce
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

BEFORE CONNECTION
Cautions and warnings
·
When making connections, do so with the power to the
•
unit switched OFF.
As for the input a nd output jacks on the amplifier,
•
"white" denotes left channel whereas "red" right
channel. Firmly make connections in correct left and
right channels.
Connect cord plugs firmly. Improper connection may
•
lead to no sound output or to generation of noise.
When disconnecting the power cord from the outlet, be
•
sure to hold its plug.
Power consumption of the AC OUTLETS
·
See that the powe r consumption doe s not exceed
•
the wattage shown on the rear panel. Do not connect
any unit other than the system equipment to the AC
OUTLETS on the rear of this unit.
Do not connect a TV monitor as it may draw a large
•
current and its wattage may exceed the allowable
value when the power is switched ON, even if the
value indicated on the TV monitor is smaller than the
allowable wattage for this unit.
Page 5
SAFETY PRECAUTIONS
Check the voltage of your local mains
supply
Singapore: AC230V
Malaysia : AC240V
The power cord should not be connected to a direct
current (DC).
If malfunction occurs
If malfunction occurs, such as noise in the sound or
odor from the unit, remove the power cord from the
AC outlet and stop using the unit immediately and
consult your local dealer.
Do not disassemble the unit
Avoid push or drop any object or
liquid into the unit
Never push or drop any kind of objects into this unit
thro ugh openings as they m ay to uch dangerous
voltage points or short-circuit parts that could result
in a fire or electric shock. Never spill any kind of liquid
on this unit. If some object/liquid has been dropped,
remove the power cord from AC outlet and consult
your local dealer.
Do not damage the Power Cord
When remove the power cord from AC outlet, always
grasp and pull the plug, not the power cord. Damage
to the power cord may cause short-circuit or shock
hazard. Power cord should not be routed to under
furniture or where it may be likely damaged.
Do not attempt to modify, repair, or disassemble the
unit, as opening or removing covers may expose you
to dangerous voltage or other hazards. There are no
user serviceable parts inside. If the unit has a problem
or breakdown in case of you attempt to modify the
unit, quality of the unit can not be guaranteed.
When you leave your home or ins tallation
location
When you leave your home for a long period of time,
turn OFF the powe r and re move th e powe r co rd
from the AC outlet. This will prevent from unexpected
accident and fire.

LEVELS OF MIC MASTER VOL CONTROL AND
MUSIC VOL CONTROL
Although usually the volume level can be varied from level
0 to a maximum level of 10, this feature allows you to
change the maximum volume level to the required setting
(such as up to 7, 8, 9, etc.).
Setting procedure
·
1. Remove the volume knob.
2. Remove the screw behind the knob, then reinstall it to
the required maximum level.
CAUTION:
Please connect higher power handling speakers when
you use this amplifier DAR-800II.
Th e maximum power of DAR-80 0II is over 36 0W/CH
peak.
Please adjust each volume to obtain proper sound level
by confirming the Input peak indicator and the Peak level
indicators to prevent over load level and distor tion. It
should be avoided handling the highest power and over
distortion since it would cause the trouble of the system.
Never listen the sound near the speakers because the
high sound pressure level will lead to ear problems.
The MIC MASTER VOL control knob and MUSIC VOL
control knob cannot turn more than the position where
the screw fixed.
Please set the maximum volume level to prevent over
leveled driven and to protect speakers.
DOOR LOCKING
The front door is available to lock from door opening for
holding each setting adjust.
To relea se the door loc k, slide the lock l ever on the
bottom of the front panel.
From the bottom view :

BASIC OPERATION
1Depress the power switch (˘) of this unit and other
equipment.
2 Connect the required number of microphones.
3Set the karaoke music machine to the play mode, then
set the MUSIC VOL control to the required level, by
checking the Peak level indicator of music input level.
4Turn the MIC VOL controls and MIC MASTER VOL
control to balance the level with that of music source,
by checking the Peak level indicator of mic input level
(MIC 1/A, 2/B, 3
Notes: 3and 4
If the peak level indicator blinks with red, input level is too
high, then reduce the input level by adjusting MUSIC VOL,
or MIC MASTER VOL controls.

MC).
5 Adjust the echo level as required.
6 Adjust the pitch using the key control buttons.
Now that the required setting is over, you do not have
to operate this unit. All you need to do is to operate the
music source equipment.
How to use microphones properly and
·
operating precautions
Keep the microphone approx. 5 to 10 cm away from
•
your mouth.
To make the voice sound clearly, leave the proper
•
space between the microphone head and holding
position on the microphone.
Do not cover the lower wind screen of the microphone.
•
As this may muffle the bass sound, defeating proper
vocal reproduction. It may also cause howling.
When you use the IR microphone system, do not cover
•
or shade the IR radiation parts (black plastic window)
of microphone at the bottom as the wireless signal is
weakened.
Provide a space of
approx. 5 to 10 cm.
Leave the proper space.
Do not use the microphone toward the speaker as it
•
may cause the feedback (howling).
