DSA254 OEM
Product information "DSA254 OEM"
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.

The SMPS1200 is a high efficiency Safety Class 2 switch mode power supply designed for use with UcD™, NCORE® and NCOREx® amplifier modules. The unit is intended for audio systems that require stable power delivery across a wide load range in a compact and lightweight format. The power supply includes an overcurrent protection mechanism that limits output current during temporary overload conditions. It also provides symmetrical auxiliary outputs and a control interface for operation with UcD™, NCORE® and NCOREx® amplifier modules. The SMPS1200 is designed to achieve low levels of radiated and conducted electromagnetic interference. The topology and layout are optimised to meet EMI requirements commonly associated with professional and high end audio applications. The power supply supports a selectable input voltage range, allowing operation with different mains supply specifications. This supports use in international applications with varying power grid standards. SMPS1200 is a 2-quadrant full bridge rectifier, making it possible to supply single ended class d amplifiers. The SMPS1200 complies with applicable safety and performance standards and is certified for use in professional audio equipmen HIGHLIGHTS • High efficiency • Small form factor • Low EMI FEATURES • 2-quadrant full bridge rectifier • Selectable input voltage range • External controlled operation • 4 variants available: A100 / A180 / A400 / A700 PROTECTIONS • Advanced Overcurrent protection • Over temperature protection • DC detection input POSSIBLE APPLICATIONS • Active Loudspeakers, for home and professional use • Line Array and Immersive Systems • Power Amplifiers, for home and professional use • Multichannel Power Amplifiers • Home Theatre Systems POSSIBLE APPLICATIONS • Active Loudspeakers, for home and professional use • Line Array and Immersive Systems • Power Amplifiers, for home and professional use • Multichannel Power Amplifiers • Home Theatre Systems Note: NCORE® and NCOREx® amplifier modules are not available for DIY customers.
The SMPS3k is a high power, high efficiency Safety Class 1 switch mode power supply designed for integration with UcD™, NCORE® and NCOREx® amplifier modules. The power supply includes an overcurrent protection mechanism that limits the output current during temporary overload conditions. If an overload persists, the unit enters hiccup mode and remains in this state until the overload condition is removed. Large primary electrolytic buffer capacitors support short term peak power delivery to the connected amplifier modules. The SMPS3k follows the same design principles for safety, quality and electrical performance as other power supplies in the SMPS family, including the SMPS400 and SMPS1200.
