Better Music Builder (M) A-4300 4-Channel Power Amplifier 1200 Watts
Better Music Builder A-4300 power amplifier provides excellent performance and impressive power for all the speakers. The A-4300 is a 4-Channel power amplifier. This 4-Channel power amplifier is one of the most powerful and innovative amplifiers on the market today.
The A-4300 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. The A-4300 features 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. The Bass Boost circuit optimized output from the power amplifier to match the characteristics of our speaker systems, resulting in extra-smooth highs and enhanced lows. 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-4300 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!
