NuPrime Evolution STA Dual-Mono Power AmplifierThe NuPrime Evolution STA offers a breakthrough in distortion reduction. Called Only Distortion Cancellation (ODC) design, it is part of their continual advancement of state of the art Class D amplifiers over the past decade. Typical feedback error correction design inverts the output signal for summation with the original input signal to derive the negative error signal, which adds to the next cycle of the input signal to form a more accurate output
