NCx122MP

Product information "NCx122MP"

The NCx122MP is a compact dual channel amplifier module based on NCOREx® Class D technology. It is designed for integration in power amplifiers and active loudspeaker systems where compact implementation and predictable electrical performance are required.

The module integrates a high efficiency switch mode power supply, a low power standby supply compliant with 2013 ERP Lot 6 requirements and two NCOREx® Class D amplifier channels on a single PCB assembly.

Control is based on a phase shift controlled self oscillating loop with feedback taken directly at the loudspeaker output. This architecture supports stable operation across varying load impedances.

The NCx122MP includes the Hypex Extension connector, allowing the addition of an auxiliary low power amplifier channel for multi way active loudspeaker designs.

NCx102EXT

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. Highlights • High efficiency • Flat, fully load-independent frequency response • Low output impedance • Very low, frequency independent THD • Very low noise Features • NCOREx® Technology • NCx-MP Add-on • External controlled operation • Specifically designed as channel extension for our Mains Powered NCORE® and NCOREx® modules Protections • Advanced overcurrent protection • Exessive DC protection • Short circuit protection • Over temperature protection Possible applications • Monitor loudspeakers for recording and mastering studios • Public address systems • Active loudspeakers
