FINAL WORDS TO USER
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

Our engineering team also designs audio equipments for

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 to avoid damaging the equipment with improper
installation and safety protection purposes.
We also provide educational and technical information on
audio equipments and technologies. For example, we
provide free installation diagrams to make it easier to
connect the system. In addition, to get best connections for
the sharpest image and sound quality, we provide hot tip for
choosing high quality A/V cables. Free information on audio
equipments and technologies is available for download on
our website, w w w.BetterMusicBuilder.com.
Please do not remove the “Yellow Label”
in the rear of the machine; otherwise, the
warranty will be void automatically. We
design it to protect your own safety. If
repair and maintenance service is needed,
please contact us directly or hire a
professional technician. To learn more
about the technical aspects, visit our website

information for review.
Before hooking up the system, turn off the AC powers on all
machines including audio/video equipment and TV.
Otherwise, it may damage the equipment, especially on the
HDTV in which a spot might appeared on the TV screen.
After hooking up the system, double check the audio/video
connections to ensure that they are connected correctly.
Sometimes, loose or poor cable quality would affect
the microphone effects, picture quality, or even cause the
machine to shut down suddenly.
Again, we must thank you for choosing a Better Music
Builder product. We hope you can make the best use of the
machine and enjoy it for years to come. If you have any

Final Words
NOTE
Any form of
tampering with this
product, will void
the warranty.
7. SYMPTOM: TOO MUCH MICROPHONE FEEDBACK
FROM THE SPEAKER.
Probable cause:
Incorrect tremble and bass adjustments on the speaker.
Remedy:
Adjust the tremble and bass to an appropriate level to avoid
microphone feedback.
8. SYMPTOM: NO SOUND FROM THE MAIN SPEAKERS
Probable cause:
Speaker connectors are not connected properly.
Remedy:
Please make sure that the speaker connectors are locked
tight. Please also note that there are two groups of speakon
connectors (i.e. Group 1 +1, –1, Group 2 +2, –2). Make
sure that your speakers have the multifunction that enables the
connection to Group 2 for different signal inputs. The basic
connection is on Group 1 (+1, –1).
9. SYMPTOM: SOMETIMES THE SPEAKERS HAVE NO
SOUND.
Probable cause:
When the master volume reaches the maximum level, the
speaker automatically shuts down because this speaker has
a built-in auto circuit to protect itself when the master volume
becomes too high.
Remedy:
Change to a higher power amplifier to work with the
speakers. Please make sure the output power of the amplifier
can match that of the speakers. Another option is to add
more speakers or subwoofers for higher output as below.
1. Add one more loudspeaker.
2. Add one more powered subwoofer.
We highly recommend hiring an audio professional for
advise on the right engineering for the amplifier and
speakers.
