High-Quality Audio Performance: Featuring the advanced TPA3116D2 HIFI Chip with AM Interference Suppression, our ZK-1002 amplifier delivers outstanding sound quality. Even during extended high-power usage, it maintains a THD (Total Harmonic Distortion) of less than 0.1%, ensuring a superior listening experience. Versatile Voltage Compatibility: The ZK-1002 supports a wide input voltage range from DC 5V to 24V, allowing it to be powered by 9V, 12V, 15V, 18V, or 24V sources. This adaptability ensures that you can easily find a suitable power supply. Dual Audio Input Options: Enjoy the flexibility of two audio input methods. You can seamlessly connect through the latest Bluetooth 5.0 technology for wireless convenience, or opt for the traditional headphone (line-in) connection for your audio source. Comprehensive Protection: Our BT amplifier is meticulously designed to safeguard your investment. It incorporates multiple protective features, including over-voltage protection, under-voltage protection, over-heat protection, and short-circuit protection. Rest assured that your device is protected in various scenarios. Optimal Power Match: Please note that achieving the best audio output requires the right combination of sufficient audio input and appropriate power supply voltage and current. Different speaker impedances will affect the relative sound power. With adequate voltage and current, higher impedance speakers will produce lower relative sound power. Pay attention to these factors to optimize your audio experience.
