Audiophonics MPA-S250NC test by Audio Science Review

Discover Audio Science Review's test of the MPA-S250NC power amplifier. This power amplifier, available in RCA and XLR versions, is a Class D stereo amplifier based on a Hypex Ncore NC252MP module. This module enables it to develop a power of up to 2x 250W at 4 ohms and 2x 150W at 8 ohms, offering a considerable power reserve while maintaining a THD+N of 0.0015% and an efficiency of 92%. The whole unit is powered by an SMPS power supply integrated into the NC252MP module for stable, clean current. Connections include speaker terminals on the output, a 12V trigger on a 3.5mm jack, and a choice of RCA or XLR input depending on the version.
