TR-AMP 800 DLS  
     
The TR Digital Audio Amplifiers use class D technology that reduces energy loss and therefore increases its performance. In fact, only 10% of the gene-rated power will be lost as heat, leaving 90% of the energy to be delivered to the speakers. Besides a higher efficiency, this system will maintain a low temperature inside the amplifier.
