Either banana plug or 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 if you are inserting 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.

CONNECTING THE MAIN SPEAKER

DX-211 is capable of driving four main speakers, which are
grouped in Group A and Group B. We recommend you
using different size of speakers for Group A (10-inch woofer
or bigger) and Group B (6-inch woofer). Under this
arrangement, Group A speaker can produce greater bass

RL

music output while Group B speaker can produce clear
vocal. The mixing of music and vocal is important to produce
quality sound for singing. Therefore, the audience can feel
different effects from Group A and Group B speakers. You
can also adjust the vocal on both speakers, or you can adjust
the vocal in either speaker by adjusting the balance.

CONNECTING THE AUDIO/VIDEO INPUT SOURCE

Before connecting the source (i.e. LD, DVD, VCD and AUX),
turn off the power for all machine, so it would protect electric
shock and prevent damage to the equipment. To connect the
AV source, the first thing to do is to connect the audio source

CONNECTING THE VIDEO OUTPUT SOURCE

The DX-211 comes with two dedicated composite video
output. Typical connection usage such as for a small
classroom show in the diagram or it can be use similarly in
connecting to the amplifier with a KTV video touch screen
stand. If 3 or 4 more is needed, use an external composite
video distributor. If the wiring distance to the output source is
more than 25 feet. A composite video amplifier distributor is
needed; otherwise, the video will be very poor.

CONNECTING THE AUDIO/VIDEO OUTPUT SOURCE

AUDIO OUT

The DX-211 is versatile. The differences for the DX-211 from the high-end models DX-222 G2 and the DX-288 G2 is that it is
less external signal line outputs for recording and connection to external power amplifiers to drive subwoofers and monitor
speakers. DX-211 is the basic model.

For example, if you are having a party, you may have guests in the living room where the DX-211 and the 5 speakers are
located; at the same time, there are people in the backyard.
That’s when this feature comes in handy. By running
additional signal out lines to the back yard where another
power amplifiers can drive the subwoofer and monitor
speakers, or hook up the signal lines to the powered
speakers can then greatly expand the entertainment area.
Please note that we recommend using the wireless
microphones in the backyard for convenience.

NOTE

If the distance from the living room to the backyard is more
than 25 feet, we recommend using an A/V distribution amplifier.

SYSTEM SETUP GUIDELINES

INSTALLATION SETUP

Through many years of experience in installation and design for Karaoke business in Asia, the engineering team of Better
Music Builder has designed two installation setups as illustrated in figure 1 and figure 2 that can produce excellent sound
performance. This design is specifically for North America.

DX-211 is a four-channel Karaoke mixing amplifier. The music
comes from main (Group-A & Group-B) speakers.

NOTE

DX-211 with four-channel output would produce different
effects from that of the 5.1, 7.1 and 7.2 home theater systems for
playing movie.

In figure 1, main (Group-A & Group-B) speakers are set up in
the front.

In figure 2, all speakers are positioned in parallel in the front.
Therefore, we recommend using different size of speakers for
main and center speakers. The reason is that main speaker
has a bigger woofer (10-inch woofer or bigger) for music and
center speaker has a smaller woofer (6-inch woofer) for clear
vocal. In addition, the vocal comes independently from the
center monitoring speaker. Therefore, the audience can feel
the better sound performance and unprecedented experience.

COMMERCIAL APPLICATIONS

For commercial or large space setup, you may need two
power amplifiers. The main amplifier is to monitor singing and
the auxiliary amplifier is for audience. Please refer to the
following diagram for hookup.

FIGURE 1

SINGER

MONITORMONITOR

If you want to set up the DX-211 inside an auditorium or a
commercial business of 2,000 square feet or more, we
recommend you to use an external power amplifier for output.
In this case, you need to “line out” and connect the AUDIO
OUT of DX-211 to a power amplifier and a speaker system
(with a 12-inch woofer) with power rating of at least 1,000W.

NOTE

We recommend you hiring a professional technician to
handle the installation for safety purpose.

KTV COMMERCIAL APPLICATIONS

Our Better Music Builder engineering team is specialized in
KTV equipment design and commercial applications. In KTV
audio signal sources (i.e. computer, DVD, VCR and cassette
deck) normally come from the DJ room. Each Karaoke room
has independent power amplifier and speakers, so it can
allow customers to freely make adjustments on music and
microphone settings in the Karaoke room. For KTV business
application, you need an audio/video distribution amplifier
(or simply called AV Distribution amplifier) if the distance
between the DJ room and Karaoke room is more than 25 feet
to make up for the loss of original signal strength.

A/V Distribution Amplifier is the perfect solution for KTV
commercial applications. It is compact, practical and
convenient for installation. You can buy this equipment at any
audio professional installation company. AV Distribution
Amplifier can strengthen the original signals to each Karaoke

DJ ROOM STORAGE EQUIPMENT

room from the DJ room. It is also the ideal choice for

USING EXTERNAL EQUIPMENT

DX-211 is not only a mixing amplifier, but it is also a
pre-amplifier specially designed for using external
equipment. When you connect other equipment to the
mixing amplifier, you may need a different type of cable
such as RCA to XLR cable. We highly recommend you using
high quality cable for connection, so it can give you the
crystal clear sound and sharp video image. Please refer to
the following figures.

duty clamping rack shelf into
the portable case. This
would protect your
equipment. There are
different sizes of the heavy
duty clamping rack shelves
to suit your specific needs.

8. VIDEO PROBLEM

10. PROTECTION FOR AUDIO/VIDEO EQUIPMENT

Symptoms: the video display appears in black and white
color only or it has unstable image.

Possible Causes:

1. Video source (i.e. DVD player) is in different formats like
NTSC or PAL. Therefore, you should select the right “Video
Format” in the “Output” of the DVD player. It is because the
video display is incompatible with the video source.

2. The video out from the amplifier to the video display has
a distance over 25 feet. Therefore, you need to add an
additional signal distribution amplifier to further enhance the
signals for longer destinations.

VIDEO BLOCK DIAGRAM

Video Signal Amplifier

KD-SCDA8

LOW MID HIGH

Video

Decoder

Video Out

3. You may be using the wrong cable for connection. The
cable for video signal is different from the cable for audio,
microphone and speaker. Therefore, you should use coaxial
cable for connection.

4. You may be using a low quality cable with poor connec­tion. We highly recommend you using high quality
audio/video cable for connection.

Before you hook up or disconnect any audio/video equip­ment, you must turn off the power for all equipments. Other­wise, it may cause black spots to appear on the LCD or
Plasma TV screen.

11. NOISE AND DISTORTION

When humming noise or displeasing sound appears, you
can replace the supplied power cord with an AC power
cord with a magnetic device as shown in the figure below.

Quali t y P o w er Cord:

105°C 3 C / 1 8 AWG 300V

12. SOUND PROBLEM

Symptom: no sound.

Possible Cause:

1. Speaker wires positive and negative touch each other at
the terminals. We recommend you using the double
banana plug.

2. “Mute” is accidentally turn on from the remote.

9. AMPLIFIER SHUT DOWN/INTERFERENCE NOISE

Symptom: the amplifier turned on but there is no music
coming out from the speaker powered output channels.

Probable cause: this unit comes with multiple switch able
AC-power. For North America its 115V and for Asia and
Europe markets are 230V.

Remedy: make sure that the AC-power supply is connected
to the correct voltage level according to the local market.
See illustration below for the proper switching of the
AC-power supply level.

3. “MUSIC GAIN” is on with music volume limit adjusted
too low.
