It is during the analog conversion that the majority of amplifier heat and waste take place.
“Digital” amplifiers are high-speed, high-efficiency “transmissions”. They work, or “switch” at much higher
rates that analog amplifiers. Digital amplifiers allow more of the power supply's energy to the speakers with
less heat and waste.

U.S. Amps T-Class™ digital amplifiers
provide the full range high-fidelity of Class
“A” and “A-B”designs, yet maintain the
high-power digital efficiency of less
sophisticated and less capable “Class D”
amplifiers.
Digital Power Processing™**
Both types function on digital principals, where they virtually “skip” the analog conversion process of “Class
A” and “A-B”. It is
and
that primarily distinguishes T-Class™ from “Class D” in
performance.
“Class-D” amplifiers are unable to equal the performance of U.S. Amps
™. The fundamental
technology of “Class D” is self-limiting.
Here's Why:
“Class D” switching uses pulse-width modulation (PWM) technology. PWM switching is
and
at a switching frequency anywhere from 75KHz to 200KHz. This produces audio output quality that is
inferior to “Class A” or “A-B,” so efficiency is gained at the expense of sonic fidelity.
