LA12X Power Amplifier

Power supply

The LA12X relies on a switched power supply (SMPS) and is equipped with power factor correction technology (PFC) controlled by a DSP, allowing it to provide 12000 W of power in voltage environments ranging from 100V to 240V.
PFC has high immunity to unstable power sources and can reduce power consumption by up to 40% under the same usage conditions. For example, the output of a specified circuit can achieve higher power (up to 16A at 240V and 30A at 120V). In addition to its high RMS rated power, its ability to transmit energy (power X holding time) will generate extreme performance from the speaker system, especially low-frequency regeneration. LA12X can have 4 analog inputs, AES and AVB. The four cascaded 24bit and 96kHz A/D converters in the front-end will generate 130dB of encoding dynamics. The digital input of AES/EBU is operated using a sampling rate converter, ranging from 44.1kHz to 192kHz. The automatic return function creates redundant audio channels with constant latency and stable levels.
The DSP operates at 96 kHz and 32 bit floating precision. This DSP combines IIR and FIR filters to produce a perfect linear phase curve and significantly improve the pulse response, giving you a more uniform, natural, transparent and real sound experience.

System protection

The latest protection system comes with advanced signal level analysis. When the sensor operates in a nonlinear domain, whether in high pulse, high temperature, or high voltage environments, it serves as a power regulator to improve the durability of the component while maintaining the highest dynamic range. The circuit design is to maintain the acoustic transparency of the system.
