The NCx122MP, a compact power dual-amplifier brick, represents the next generation of Class D amplification, incorporating our advanced NCOREx® technology.
Building on the proven performance of NCORE® and leveraging insights from our latest Nilai technology, the NCx122MP offers exceptional audio fidelity and efficiency in an integration-friendly design. This versatile module is ideal for a wide range of audio applications — from high-quality power amplifiers to high-performance active loudspeakers.
At the heart of the NCx122MP is a dual, self-contained, high- performance NCOREx® Class D amplifier. NCOREx® is a continuation of the NCORE® lineage, enhanced by Nilai research that has significantly improved the loop filter. This enhancement enables a >75dB loop gain across the entire audio band, providing ultra-low harmonic distortion, intermodulation distortion and negligible output impedance. The result is an amplifier that delivers transparent and dynamic audio with >60dB error correction throughout the audio spectrum, dramatically reducing distortion from the power stage and output filter.
The control mechanism is based on an upgraded phase-shift-controlled, self-oscillating loop, ensuring precise and clear audio reproduction. Combined with a flat frequency response regardless of load impedance and minimal electromagnetic interference (EMI), the NCx122MP guarantees pristine sound quality.
The power supply architecture of the NCx122MP has also been refined, featuring a highly-efficient switch mode power supply (SMPS) with synchronous rectification on the main output rails. The integrated low-power standby supply complies with 2013 ERP Lot 6 0.5W requirements, optimising energy efficiency. An automatic input voltage doubler enhances universal mains compatibility, making the NCX122MP suitable for diverse environments and applications.
To further expand its versatility, the NCx122MP is equipped with the Hypex Extension connector, enabling the integration of an additional low-power tweeter amplifier channel. This feature allows for advanced multi-way loudspeaker configurations, making the NCx122MP a flexible and powerful solution for demanding audio applications.ΩΩ
