NC500 OEM
Product information "NC500 OEM"
The NC500 OEM is an NCORE® amplifier module developed as a successor to the earlier UcD™ module family. It is a Class D amplifier design intended for applications that require high measured performance combined with efficient power operation.
The amplifier is based on a non hysteresis fifth order self oscillating control loop that applies feedback directly at the loudspeaker output. This control concept is intended to reduce load dependency and distortion across the operating range and contributes to predictable electrical behaviour.
The NC500 OEM is designed as an unbuffered amplifier module. This allows system designers to implement an external input buffer according to their own design requirements. The absence of an integrated buffer supports flexible system tuning and integration without imposing a fixed input stage topology.
The module includes a differential audio input to support robust signal transmission and reduce sensitivity to external interference. This supports signal integrity when integrated into larger audio systems.
Typical applications include high end stereo and multichannel power amplifiers active loudspeakers for studio monitoring and mastering as well as premium home theatre systems.
The NC500 OEM is specified with conservative operating margins and component ratings. This design approach is intended to support long term reliability under normal operating conditions in professional and high end audio applications.

Recommended additional parts
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.
