INTRODUCTION
The wait is over! 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!
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.
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.
