PROFESSIONAL POWER AMPLIFIER
The wait is over! The much anticipated stereo power
amplifier from Better Music Builder has arrived! And it comes
in two models: A-3 and A-4. A-3 is a 3-Channel and A-4 is
a 4-Channel power amplifier. If you’re really looking for
something to bring life to your party, bring this along and
you’ll have a blast!
A Series is equipped with the following
distinguished features:
Models: A-3
A-4
This new series 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 amplifier ever.
When you’re using the best components and the most
advanced technology, cutting the total weight wasn’t that
difficult. And to officially make this the most portable
amplifier, we’ve included front handles so you can lug the
machine with ease.
• 3-Channel and 4-Channel power amplifier
• Sleek aluminum chassis
• Signal level indicator for each channel
• Link and Alone work mode
• Power overload protection
• Sophisticated Turbo-Cooling System helps extend life
• Variable fan speed is automatically adjusted by
temperature
• Anti-dust ventilation grill
• Front handles for portability
• Gain has two settings: 32dB and 0.775V
• Inputs: 3 or 4 XLR audio inputs
• Outputs: 3 or 4 dual-banana audio outputs
Considering how much power the A Series 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.

OVERLOADING
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.
Do not overload wall outlets, extension cords or convenience
receptacles beyond their capacity, since this can result in fire
or electric shock.
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
An appliance and cart combination

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

This diagram gives you an idea of how to connect three
speakers to the 3-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.

after the system finish self-inspection.
2. 32dB indicator shows the channel has output signals.
3. 12dB indicator shows the channel has output power
closed 10% of RMS.
4. 3dB indicator shows the channel has output power 50%
higher than RMS.
5. 0dB indicator shows the channel reached its full power
output. At this time, there will be clip distortion.
6. When power is On but any indicator is Off, it means the

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
side outlets.

Troubleshooting
TROUBLESHOOTING
1. NO SOUND: Power indicator is Off.
5. BAD AUDIO OR MICROPHONE SOUNDS
REMEDY:
REMEDY:
• Check the AC Plug.
 Check the source of audio (CD, DVD) to see if it’s
scratched.
• 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 audio cables or microphone cables.
 Use a better audio cable or 3pin XLR microphone cable.
• 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.
6. THERE IS NO PICTURE
REMEDY:
 Check to see if video sources are selected accordingly.
2. NO SOUND: The power indicator light is On but -32dB
light (signal light) is Off.
 Check to see if plugged in the video cables are plugged in.
 Check TV or display monitor.
REMEDY:
 If the POWER indicator LED is On and the fan is running,
but the signal LEDs 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.
7. VIDEO IS FLICKERING
REMEDY:
 Check to see if the AV cable is damaged.
 Check audio cables or microphone cables.
 Use a better AV cable.
 Use a better audio cable or 3pin XLR microphone cable.
 We recommend connecting videos to the TV or monitor
directly for best results.
 Ensure microphone is On.
 Check the microphone volume.
8. POWER CAN NOT BE TURNED ON
REMEDY:
3. 0dB (OVERLOAD INDICATOR) IS ON & SOUND IS
ABNORMAL
 Check to see if unit is plugged in properly.
 Check power cable.
REMEDY:
 Sound of music signal output amplitude is too high.
 The gain level is set too high.
9. PROTECTION FOR AUDIO/VIDEO EQUIPMENT
 Ensure the output connection is connected correctly and
then reboot the machine.
Before hooking up or disconnecting any audio/video equipment, turn off the power for all equipment. Otherwise, it may

Final Words
11. NOISE AND DISTORTION
The engineering team of Better Music Builder has many
years of experience in audio equipment design. The team
constantly develops new audio technologies, designs
innovative audio and karaoke equipment to suit your specific
needs and provides you great ideas for home entertainment.
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.
Our engineering team also designs audio equipment for
commercial use by restaurants, coffee shops, churches, and
school auditoriums, etc. If the commercial area for audio
equipment installation exceeds 2,000 square feet, we highly
recommend hiring audio professionals to handle the
installation in order to avoid risks in breaking the equipment
with improper installation and safety protection purposes.
