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.

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 cause black spots to appear on the LCD or Plasma TV screen. 4. SIGNAL LED IS NOT RESPONDING TO SIGNAL LEVEL 10. AMPLIFIER SHUT DOWN/INTERFERENCE NOISE 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. 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. 18 Final Words 11.
