Quoted from Tripath Technologies' website:
"Class-T® digital amplifiers provide the audio fidelity of traditional linear (Class-A/B) amplifiers with more than twice the power efficiency of these devices. This leads to higher levels of integration and smaller packages at the semiconductor level. At the system level, these advantages reduce the size of power supplies and heat sinks and significantly reduce the heat management challenges of today's dense, complex electronic systems. While pulse width modulated (PWM) switching amplifiers (Class-D) can also achieve similar power advantages, none have been able to do so without a significant compromise in audio fidelity. Hence Tripath's new designation, the Class-T® digital amplifier the new standard in audio performance and power efficiency."

Class-T® digital power amplifiers are both highly efficient and sonically pure. Utilizing this technology, we've designed our audio amplifiers to produce high powered output, while consuming less power from your motorcycles 12 volt system. The result is undeniable; Pure raw clean sound without the dead battery.
