INTRODUCTION

Better Music Builder the new A Series power amplifier in two

models: A-1600 and A-1800 provides excellent performance

and impressive power for all the speakers. Both of the

A-1600 and A-1800 are a 2-Channel power amplifier. This

2-Channel power amplifier is one of the most powerful and

innovative amplifiers on the market today. If you’re really

looking for something to bring life to your party, bring this

along and you’ll have a blast!

The A-1600/A-1800 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. They feature 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. 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-1600/A-1800 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

Conn ection

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.

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.
