It supports a wide voltage input of 18–36V and delivers powerful output up to 220W × 2 + 350W (PMPO). • Treble & Bass Control If you’re tired of amplifiers with only a single volume knob, this board is a great upgrade. With dedicated treble and bass controls, you can fine-tune your sound, add depth, and enjoy richer, more impactful bass. • Highly Compatible Power Input Most DC adapters on the market (5.5mm × 2.1mm plug) work perfectly with the ZK-AS21. Don’t have a DC plug? No problem—you can also connect the positive and negative wires directly to the power socket on the board. • Built-in Protection Features The ZK-AS21 includes multiple safety protections such as short-circuit, under-voltage, over-voltage, and clipping protection to ensure safe and stable performance. • Reliable 24×7 After-Sales Support Customer satisfaction is a priority. If you have any questions or face any issues with the product, the support team is available 24/7 to provide a helpful and satisfactory response. • Product Disclaimer The product is exactly as shown in the images.
