HPA D-Series Lightweight Audio Power Amplifier

The light weight and simple to use built in features, as well as robust circuitry make the D-Series amplifier range an obvious choice for mobile band and DJ rigs. The versatile features allow setup in virtually any system, without the need for adding extensive amounts external equipment.

 

When state of the art amplifier technology is combined with a high quality switch mode power supply and D class amplifier design, you get the highest audio resolution and efficiency.  They are much more efficient than conventional amplifiers, they run cooler, lighter, and don't require massive heat sinks and heavy transformers.
This revolutionary amplifier offers the sonic superiority and great 
reliability  in an extremely efficient and lightweight design. Advanced protection circuitry allows operation with greater efficiency into any load condition, under any power conditions.
Thermal limiting circuitry ensures stable operation into loads as low as 2 ohms. This thermal limiting circuitry also ensures powerful sound even in extreme overload conditions.

The light weight and simple to use built in features, as well as robust circuitry make the D-Series amplifier range an obvious choice for mobile band and DJ rigs. The versatile features allow setup in virtually any system, without the need for adding extensive amounts external equipment.
