PS1000R85

The DSA254 OEM is an audio amplifier module designed for use in both conventional low impedance loudspeaker systems and 70 Vrms and 100 Vrms distribution systems. The module supports multiple output configurations, including single ended, bridge tied load and parallel bridge tied load operation, allowing adaptation to different system requirements. The amplifier is intended for integration in a wide range of professional audio applications where flexibility in loudspeaker topology is required. A single DSA254 OEM based design can be used for low impedance installations as well as high voltage distribution systems without changes to the amplifier topology. The DSA254 OEM is based on NCOREx® Class D amplifier technology. This architecture supports stable operation across a wide range of load impedances, allowing the module to drive both low impedance loudspeakers and high impedance distribution lines with consistent electrical behaviour. The design also supports reliable operation in installations with long cable runs, commonly encountered in 70 V and 100 V systems. For high voltage distribution applications, the DSA254 OEM uses high voltage semiconductor output stages to drive 70 V and 100 V lines directly. This removes the need for an external step up transformer, reducing system weight and simplifying mechanical and electrical integration. The DSA254 OEM is intended for professional audio systems where a single amplifier platform must support multiple output configurations and loudspeaker types. Its design allows system designers to cover a broad range of applications using one amplifier module.

Note: The NCx1400 OEM is not for sale yet. However, we expect to ship it in Q4, 2026. Please contact sales@hypex.nl for more information on the NCx1400 OEM. The NCx1400 OEM is a full bridge Class D amplifier module based on NCOREx® technology. Positioned as a higher output power variant within the NCOREx® family, NCx1400 OEM builds on the design principles used in the NCx500 OEM. Compared with the NCx500 OEM, the NCx1400 OEM provides increased output power, delivering at least twice the power into 4 Ohm. The full bridge configuration supports higher voltage swing and output capability while maintaining the performance characteristics associated with the NCOREx control architecture. The NCx1400 OEM benefits from further optimisation of noise and total harmonic distortion relative to earlier NCORE based designs. These improvements are the result of refinements to the NCOREx® control loop and output stage implementation. The module is designed to extend the NCOREx® product family and supports partial pin compatibility with other NCOREx® modules. This allows system designers to upgrade existing designs with limited changes to the surrounding hardware. Like its sibling, the NCx500 OEM, NCx1400 OEM is also fitted with a user-selectable high quality buffer stage. Depending on system requirements, customers can choose to use the module with or without this buffer stage through on-board jumper connectors. The NCx1400 OEM is intended for use in high power audio systems, including professional audio equipment and high end home audio applications, where increased output power, low noise and predictable electrical behaviour are required. HIGHLIGHTS • Low idle losses • Extremely low distortion across the frequency and power range • Exceptionally low output impedance for precise speaker control • Extremely low noise for a pure audio experience • Remarkably neutral and transparent sound reproduction FEATURES • On-board high-end buffer stage • SMPS dependent High-Current/High-Voltage mode • Built with thoughtfully chosen, superior-quality components PROTECTIONS • Overcurrent protection • DC error detection • Over- and undervoltage protection • Over temperature protection • Short circuit protection POSSIBLE APPLICATIONS • Home Theatre systems • Power Amplifiers; for home and professional use • Immersive Audio systems • Multichannel Power Amplifiers

The NCx500 OEM is an amplifier module based on the NCOREx® Class D technology. Compared with the earlier NC500 OEM, the NCx500 OEM provides improved measured performance, including lower noise and reduced total harmonic distortion. The module is designed for use in mono, stereo, multichannel and active loudspeaker applications. Its electrical and mechanical interface allows it to function as a direct replacement for the NC500 OEM in existing designs, supporting straightforward system upgrades without changes to the surrounding circuitry. The NCx500 OEM includes functional and performance updates relative to the NC500 OEM, reflecting further optimisation of the NCORE® based control architecture. These refinements are intended to improve overall system performance while maintaining compatibility with established NCORE® based designs. NCx500 OEM is fitted with a user-selectable high quality buffer stage. Depending on system requirements, customers can choose to use the module with or without this buffer stage through on-board jumper connectors.
