The NCx102EXT is an NCOREx® based Class D amplifier add on module for the NC-MP / NCx-MP series. It is intended for use in active loudspeaker systems as an additional amplifier channel, optimised for mid and high frequency reproduction while supporting full audio bandwidth operation.
The module is powered directly from the host NC-MP or NCx-MP module via the Hypex Channel Extension interface. It supports a wide input voltage range compatible with the complete NC-MP / NCx-MP product range and does not require an external power supply.
The NCx102EXT incorporates a self contained NCOREx® Class D amplifier. The design provides a flat frequency response independent of load impedance and maintains consistent distortion behaviour across the operating range. Radiated and conducted electromagnetic interference is controlled through circuit topology and PCB layout.
Control is based on a phase shift controlled self oscillating loop with feedback taken directly at the loudspeaker output. This architecture supports stable operation and predictable electrical behaviour when integrated into multi channel active loudspeaker systems.
The NCx102EXT is designed to expand NC-MP and NCx-MP based designs with additional amplifier channels, supporting two-way, three-way or four-way active loudspeaker configurations where an additional midrange or high-frequency channel is required.
