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.
