INTRODUCTION
Better Music Builder A-4300 power amplifier provides
excellent performance and impressive power for all the
speakers. The A-4300 is a 4-Channel power amplifier. This
4-Channel power amplifier is one of the most powerful and
innovative amplifiers on the market today.
The A-4300 power amplifier is designed by the best minds
here in Better Music Builder to make this the most efficient,
most durable, and of course the best designed power
amplifier ever. The A-4300 features Better Music Builder’s
latest Auto Temperature and Loads Compensated Impedance
and DDT™ (Distortion Detection Technique) circuitry for
clean, undistorted sound with the ultimate circuit protection
needed by amps which often get pushed to the limit. DDT
protects drivers and ensures that sonic integrity is maintained,
even in extreme overload conditions. The Bass Boost circuit
optimized output from the power amplifier to match the
characteristics of our speaker systems, resulting in
extra-smooth highs and enhanced lows. And to officially
make this the most portable amplifier, we’ve included front
handles so you can lug the machine with ease.
Considering how much power the A-4300 can bring, it
needs a sophisticated cooling system. That’s where the
patented Turbo-Cooling System from Better Music Builder
comes in. Using the new technology, the system aligns the
amplifier’s massive heat sinks to provide maximum cooling.
Also, the fan speed is programmed to vary automatically
based on temperature. What all this means is that the system
extends the life of power transistors by maintaining safe
internal temperatures.
Better Music Builder is simply the best solution for home and
professional karaoke performance!

OVERLOADING
Do not overload wall outlets, extension cords or convenience
receptacles beyond their capacity, since this can result in fire
or electric shock.
An appliance and cart combination
should be moved with care. Quick
stops, excessive force and uneven
surfaces may cause the appliance and
cart combination to overturn.
Do not place the electronic equipment onto the unstable
table or stand. It is because it would fall easily from the
unstable table or stand,
so it may cause
accident including
personal injuries and
damage the equipment.
Please follow our
instructions to install the
equipment, or you may
hire a professional
technician to handle the
installation for safety
purpose.
Do not place the set on an unstable cart, stand, tripod,
bracket, or table. The set may fall, causing serious injury to
a child or an adult and serious damage to the set. Use only
a cart stand tripod, bracket, or table recommended by the
manufacturer.
For the set with a three-wire grounding type ac plug:
This plug will only fit into a grounding-type power outlet.
This is a safety feature. If you are unable to insert the plug
into the outlet, contact your electrician to have a suitable
outlet installed. Do not defeat the safety purpose of the
grounding plug.
120V AC-POWER
Do not store the electronic equipment near water or area
with moisture such as bathroom, kitchen sink, laundry area
and swimming pool, etc.
Do not transport the electronic equipment by yourself if its
weight exceeds 70 pounds. It is recommended that two
people work together to transport the equipment or by using
hand truck and the like.
Do not place the electronic equipment directly under
sunlight or close to the window. It may cause overheat on
the electronic equipment by the sunlight.
Do not block the openings and vents in the cabinet which
is designed for the ventilation of the electronic equipment.
The blocking may cause overheat in the electronic equipment
because of insufficient circulation of air, so it would damage
the electronic equipment.

SPEAKER CONNECTION METHODS AND INFORMATION
Connection
CONNECTOR INFORMATION
Either banana plug or wire insert type can be used to
connect the unit to speakers. Be sure to connect red (+) to red
(+) and black (–) to black (–). Otherwise, the sound output
would be 180° out of phase and distorted.
Follow these steps to insert the wire directly into the speaker
terminal.
1. Strip off the vinyl covering and twist the tip of the
wire core.
2. Loosen the knob and insert the wire core into the
terminal hole.
3. Tighten the knob to fix the wire core in place.
Do not allow the wire core to protrude or touch other
terminals or wires, otherwise, damage may occur.

This diagram gives you an idea of how to connect two
speakers to the 2-Channel power amplifier. If it’s used in a
bigger room that’s in excess of 1,000 square feet, you may
need two other speakers acting as rear speakers. When
doing so, a second 2-channel power amplifier is required.

AIR VENTILATION
This series of amplifiers use the same ventilation structure.
First, cool air enters through the front panel. While inside, it
goes through the transformer and enters the fan. And then it
is finally compressed into the radiator and flows out from the
rear outlets.

TROUBLESHOOTING
1. NO SOUND: Power indicator is Off.
REMEDY:
• Check the AC Plug.
• Ensure that the AC outlet works by testing other devices. If
too many amplifiers are used on one outlet, the building's
circuit breaker may trip and shut off power.
• Check the overload switch located on rear panel.
• An amplifier that keeps shutting off may have a serious
internal fault. Turn it off, remove AC power, and have the
amplifier serviced by a qualified technician.
2. NO SOUND: The power indicator light is On but signal
light is Off.
REMEDY:
If the POWER indicator LED is On and the fan is running,
but the signal LED indicate no signal, check the input. Make
sure the signal source is operating and try another input
cable. Connect the source to another channel or amplifier to
confirm its operation.
Check audio cables or microphone cables.
Use a better audio cable or 3pin XLR microphone cable.
Ensure microphone is On.
Check the microphone volume.
3. DDT (DISTORTION DETECTION TECHNIQUE) LED
INDICATOR IS ON & SOUND IS ABNORMAL
REMEDY:
Sound of music signal output amplitude is too high.
The gain level is set too high.
Ensure the output connection is connected correctly and
then reboot the machine.
4. SIGNAL LED IS NOT RESPONDING TO SIGNAL LEVEL
REMEDY: If the SIGNAL indicator is lighting normally, the
problem may be between the amplifier and the speaker.
Check the speaker wiring for breaks. Try another speaker
and cable.
Troubleshooting
5. BAD AUDIO OR MICROPHONE SOUNDS
REMEDY:
Check the source of audio (CD, DVD) to see if it’s
scratched.
Check audio cables or microphone cables.
Use a better audio cable or 3pin XLR microphone cable.
6. THERE IS NO PICTURE
REMEDY:
Check to see if video sources are selected accordingly.
Check to see if plugged in the video cables are plugged in.
Check TV or display monitor.
7. VIDEO IS FLICKERING
REMEDY:
Check to see if the AV cable is damaged.
Use a better AV cable.
We recommend connecting videos to the TV or monitor
directly for best results.
8. POWER CAN NOT BE TURNED ON
REMEDY:
Check to see if unit is plugged in properly.
Check power cable.
9. PROTECTION FOR AUDIO/VIDEO EQUIPMENT
Before hooking up or disconnecting any audio/video equip-
ment, turn off the power for all equipment. Otherwise, it may
cause black spots to appear on the LCD or Plasma TV screen.
10. AMPLIFIER SHUT DOWN/INTERFERENCE NOISE
CAUSE: The amplifier turned On but there is no music coming
out from the speaker powered output channels.
REMEDY: Ensure that the AC-power supply is connected to the
correct voltage level according to your region.
18
11. NOISE AND DISTORTION
When humming noise or displeasing sound appears, replace
the supplied power cord with an AC power cord with a
magnetic device as shown in the figure below.
In North America many families own satellite TVs, HD TVs
and cable TV receivers. They may cause interference which
affect both audio and video equipment. The power cord as
shown in figure 2 may help eliminate the humming sound
and enhance TV picture quality.
12. SOUND PROBLEM: No sound.
REMEDY:
Positive and negative of
speaker wire are touching
each other at the terminals.
We recommend the usage
of double banana plugs.
3 prong to 2 prong adaptor
110V~120V
