1. Core features

1. Power performance and driving capability: The rated mono output power reaches 240W (40 load), and the peak power is higher. It can easily drive low-impedance, large-dynamic speakers (such as 8-inch and above subwoofers, high-sensitivity bookshelf boxes).

2. Sound quality performance and technical advantages: Using TI PurePathHD technology, the total harmonic distortion (THD+N) is as low as 0.003%, and the signal-to-noise ratio (SNR) is as high as 112dB, achieving near-lossless audio restoration, with delicate vocals and rich instrumental details. Supports 24bit/192kHz high-resolution audio input, is compatible with various lossless music formats, and fully unleashes the potential of high-fidelity audio sources.

3. Efficiency and heat dissipation design

The efficiency of the Class D amplification architecture exceeds 90%, and the heat generated during operation is much lower than that of traditional Class AB amplifiers. It only requires a small heat sink to operate stably, and is suitable for compact equipment design.

Built-in over-current, over-temperature, short-circuit, and under-voltage protection, and automatic shutdown under extreme working conditions to ensure the safety of the module and speaker.

2. Applicable scenarios and advantages

DIY for Hi-Fi enthusiasts: The circuit design is streamlined and there are few peripheral components. It is suitable for building cost-effective desktop Hi-Fi systems or customized speakers. Home theater upgrade: High-power output can drive a subwoofer, and it can be paired with a multi-channel preamp to achieve theater-level low-frequency impact. Professional audio engineering: Stable performance and high power reserve, suitable for small performances, conference room sound reinforcement, background music systems and other scenarios.
