NC122MP OEM
The NC122MP is a compact dual channel amplifier module designed for use in power amplifiers and active loudspeaker systems. The module integrates power supply and amplification functions on a single PCB assembly.
The NC122MP includes an integrated power supply architecture consisting of a low power standby supply compliant with 2013 ERP Lot 6 requirements for a maximum standby consumption of 0.5 W, a regulated switch mode power supply and two 125 W NCORE® Class D amplifier channels.
The amplifier section consists of two self contained NCORE® Class D amplifiers. 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. The amplifier operates using a phase shift controlled self oscillating loop with feedback taken at the loudspeaker output.
The main power supply is a compact, regulated half bridge switch mode converter with synchronous rectification on the main output rails. The supply is designed specifically for Class D audio amplifier operation and supports efficient power delivery under typical audio load conditions.
An automatic input voltage doubler is included to support universal mains input operation. For applications requiring standby functionality, the NC122MP integrates a dedicated low power standby switch mode power supply designed to minimise energy consumption during idle periods.
The NC122MP includes the Hypex Extension connector, which allows the addition of an auxiliary low power amplifier channel. This supports system designs such as three way active loudspeakers where an additional tweeter amplifier channel is required.
