NuPrime Evolution STA-SE - Stereo Power Amplifier

The NuPrime Evolution STA-SE is a stereo power amplifier combining Only Distortion Cancellation Class D circuitry with an ANC GaN power supply. The ODC circuit extracts its correction signal from the MOSFET devices and output filter. The amplifier operates at a 650 kHz switching frequency.

Its dual-phase interleaved GaN supply uses active noise cancellation to address mains noise and ripple, while GaN power modules supply the amplifier stages. NuPrime specifies 400 watts per channel into both 8 and 4 ohms. Trigger input and output connections support system integration, and the low-profile full-width chassis is available in Black or Silver.
