• Do not use the device in a confined, poorly-ventilated
location. If this device is to be used in a small space
other than an EIA-standard rack, make sure that there is
adequate space between the device and surrounding
walls or other devices: at least 30cm at the sides, 30cm
behind and 30cm above. Inadequate ventilation can
result in overheating, possibly causing damage to the
device(s), or even catch fire.

NOTE
NOTE
• Do not use the speaker’s handles for suspended installation.
Doing so can result in damage or injury.
• Do no expose the device to excessive dust, vibrations,
extreme cold or heat (such as in direct sunlight, near a
heater, or in a car during the day) to prevent the possibility
of panel disfiguration or damage to the internal
components.
• Do not place the device in an unstable position where it
might accidentally fall over.
CONNECTIONS
• Before connecting the device to other devices, turn off the
power for all devices. Before turning the power on or off
for all devices, set all volume levels to minimum.
CAUTION
• When turning on the AC power in your audio system,
always turn on the device LAST, to avoid speaker damage.
When turning the power off, the device should be turned
off FIRST for the same reason.
• Do not insert your fingers or hands in any gaps or
openings on the device (ports, etc.).
• Avoid inserting or dropping foreign objects (paper, plastic,
metal, etc.) into any gaps or openings on the device
(ports, etc.). If this happens, turn off the power immediately
and unplug the power cord from the AC outlet. Then
have the device inspected by qualified Better Music
Builder service personnel.
• Do not use the device for a long period of time at a high
volume level, since this can cause permanent hearing loss.
If you experience any hearing loss or ringing in the ears,
consult a physician.
• Do not operate the device if the sound is distorting.
Prolonged use in this condition could cause overheating
and result in fire.
• Do not rest your weight on the device or place heavy
objects on it, and avoid using excessive force on the
buttons, switches or connectors.
GETTING STARTED
WIRING
IMPORTANT: Make sure all equipments are turned off before
making any connections.
For speaker connections, use a high-quality speaker wire with
polarity coding. The side of the wire with a ridge or other
coding is usually considered positive polarity.
If desired, consult Better Music Builder technical
support for speaker wire and connection options.
The speakers have coded terminals that accept a variety or
wire connectors.
To ensure proper polarity, connect each + terminal on the
back of the amplifier or receiver to the respective + (red)
terminal on each speaker. Connect the – (black) terminals in
a similar way. See the owner’s guides that were included
with your amplifier, receiver and television to confirm connec-
tion procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +)
when making connections. Doing so will cause poor imaging
and diminished bass response.
ADJUSTING
Check the speakers for playback, first by setting the system
volume control to a minimum level, and then by applying
power to your audio system. Play a favorite music or video
segment and increase the system volume control to a comfort-
able level.
You should hear balanced audio reproduction across
the entire frequency spectrum. If not, check all wiring connec-
tions or consult the authorized dealer from whom you
purchased the system for more help.
The amount of bass you hear and the stereo-image quality
will be affected by a number of different factors, including the
room’s size and shape, the construction materials used to
build the room, the listener’s position relative to the speakers,
and the position of the speakers in the room.
Listen to a variety of music selections and note the bass level.
If there is too much bass, move the speakers away from
nearby walls. Conversely, if you place the speakers closer to
the walls, there will be more bass output.
CARING
Each enclosure has a finish that does not require any routine
maintenance. When needed, use a soft cloth to remove any
fingerprints or dust from the enclosure or grille.

EXAMPLE OF SPEAKON CONNECTOR
There are two groups on the speakon connectors: Group 1
(+1, –1) and Group 2 (+2, –2) as indicated in the diagram. In
order to use it, your speaker must have multi-functions (i.e.
enable two sources of signal for input). If your speaker does
not have multi-functions, it would not work with the Group 2
for connection. Please refer to the following diagram for
connection.
SYSTEM APPLICATIONS
Applications
Speakon Outputs
The upper Speakon jack has both Channel 1 and
Channel 2 outputs, so it is especially useful for parallel,
bi-amp, or BRIDGE mono operation. The other Speakon
carries only Channel 2's output. See the illustrations at
above.

Troubleshooting
TROUBLESHOOTING
1. SYMPTOM: NO SOUND COMING OUT FROM THE
SPEAKERS
Probable causes:
1. The A/C power of the speaker is turned off.
2. Wrong A/C power selection (i.e. 110V~ 220V).
Remedy:
A. Turn on the A/C power of the speaker.
B. Make sure the receiver or amplifier is on and the source is
playing.
C. Check all wires and connections between receivers,
amplifiers and speakers. Make sure all wires are connected,
none of the speaker wires are frayed, cut or punctured, and
that no wires are touching each other.
D. Review proper operation of your receiver or amplifier.
E. Choose the right A/C power.
2. SYMPTOM: NO SOUND COMING OUT FROM ONLY
ONE SPEAKER
Probable cause:
The A/C power of the speaker is turned off.
Remedy:
A. Check the "Balance" control on your receiver or amplifier.
B. Check all wires and connections between receiver,
amplifier and speaker. Make sure all wires are connected,
none of the speaker wires are frayed, cut or punctured, and
that no wires are touching each other.
C. In Dolby®Digital or DTS®mode, make sure that the
receiver or processor is configured so that the speaker in
question is enabled.
D. Turn off all electronics and switch the speaker in question
with another speaker that is working correctly. Turn
everything back on, and determine whether the problem is in
the same place: i.e., the speaker that was working previously
now has no sound and the speaker that was not working
now sounds fine. If the problem is in the same place, the
source of the problem is most likely with your receiver or
amplifier, and you should consult the owner's manual for
further information. If the problem is with the speaker, consult
your dealer for further assistance, or visit our web site for
technical support.
3. SYMPTOM: NOISE FROM THE SPEAKER.
Probable cause:
The A/C power cord of the speaker is not grounded.
Remedy:
Change a new magnet cord of the A/C power cord.
4. SYMPTOM: MICROPHONE VOLUME IS TOO LOW.
Probable causes:
A. The microphone is poorly connected to the speaker.
B. The volume on the speaker is too low.
Remedy:
A. Check the connection between the microphone and the
speaker. Make sure that they are connected properly.
Condense microphone doesn't work with the speaker. You
may need to change to a dynamic vocal microphone.
B. Turn the volume to an appropriate level. If the volume is
still not high enough, you may need to upgrade your existing
audio system to a system with much higher output.
5. SYMPTOM: CRACKING NOISE FROM THE SPEAKER.
Probable cause:
The tweeter may be burned out.
Remedy:
Replace with a new tweeter.
Note: we recommend hiring a professional to change a
tweeter in order to do it properly.
6. SYMPTOM: SOUNDS LIKE DAZZ, DAZZ, DAZZ ........
COMING FROM THE SPEAKER.
Probable cause:
The speaker cable (with small gauges) is over 100 feet.
Remedy:
Change to a higher quality cable preferably 12 and 14
gauges.

15
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.
