What Stands Out
Product Details
- 2.1CH Subwoofer Audio Amplifier Board The ZK-AS21P amplifier board features a 2.1-channel design, allowing you to connect two passive speakers and a subwoofer. Equipped with treble/bass adjustment knobs, an independent subwoofer volume control, and a 20-200Hz frequency adjustment knob, it delivers optimized audio performance for audiophiles. Fine-tune the sound to experience deeper bass, crisper highs, and a more immersive, layered soundstage.
- HIFI-Grade Audio Amplifier Powered by dual TPA3255 amplifier chips—high-performance Class D modules that ensure ultra-low distortion across the entire frequency range while delivering crystal-clear HD audio. The PCB utilizes advanced windowed tin-sprayed traces to enhance power output, while six low-noise NE5532 preamplifiers refine sound quality, boost volume, and improve gain.
- Massive 300W×2 + 600W Output Packs 300W per channel (left/right) and a staggering 600W subwoofer output, effortlessly driving high-power speakers and subwoofers. Requires an 18-50V DC/10A+ power supply (wider voltage input: 18-50V DC). Note: Higher voltage/current and lower speaker impedance increase output power—always use a PSU rated above the amplifier’s operational demand.
- Versatile Audio Inputs Supports Bluetooth 5.1 (faster transmission, lossless decoding, <15m range), USB flash drives, USB sound card mode, and 3.5mm AUX input. Pro tip: Disconnect Bluetooth when using AUX for uninterrupted playback.
- Advanced Protection & Cooling Built-in safeguards: over/under-voltage, overheating, and short-circuit protection. A whisper-quiet, long-life cooling fan (stall-proof, noiseless) sits atop the amp chips, ensuring optimal heat dissipation and reliability.
