The NCx252MP is a compact dual channel amplifier module based on NCOREx® Class D technology. The module is designed for integration in power amplifiers and active loudspeaker systems where compact implementation and predictable electrical performance are required.
The NCx252MP integrates a low power standby supply compliant with 2013 ERP Lot 6 requirements for a maximum standby consumption of 0.5 W, a high efficiency switch mode power supply and two NCOREx Class D amplifier channels. The integrated architecture supports compact power delivery within a single PCB assembly.
The amplifier section is based on the NCOREx® control architecture and is designed to provide stable operation across varying load impedances. The integrated power supply supports efficient operation under typical audio load conditions.
The NCx252MP includes the Hypex Extension connector, allowing the addition of an auxiliary low power amplifier channel. This supports system designs such as multi way active loudspeakers where an additional tweeter amplifier channel is required.
