CS8673E Dual-Channel 50Wx2 Audio Amplifier Board Compatible with Bluetooth 5.1 Stereo AMP Amplifier Features: 1. CS8673E Microchip: The CS8673E chip inside this audio amplifier board features a high-efficiency, low-distortion Class-D audio power amplification circuit with noise suppression. It delivers clear and powerful sound quality and includes overcurrent protection, short-circuit protection, and auto-recovery overheating protection to prevent chip damage under abnormal operating conditions. 2. Bluetooth 5.1-Compatible Amplifier: With a transmission range of up to 15 meters (unobstructed), this audio power amplifier supports 2.0-channel stereo output, delivering 50W × 2 (left and right channels) pure audiophile-grade HIFI sound quality. High frequencies are crisp and clear, midrange is smooth and delicate, and bass is powerful and impactful. 3. USB Playback Support: This stereo AMP amplifier supports playback from a USB drive. Simply connect the USB drive, switch to “USB” mode in the app, and you’re ready to play. Note that the USB interface is a Type-C port. 4. USB Audio Card Function: This power amplifier board outputs high-quality audio signals to speakers via USB, offering superior sound quality compared to a computer’s built-in sound card. Connect the Bluetooth-compatible board to your computer using a data cable, switch to “Audio Card” mode in the app, and you’re ready to play music through your computer’s media player. 5. Smartphone App Control: Compatible with Android and iOS systems, the app allows control of playback mode, volume, equalizer, track selection, and more. You can also rename the digital audio amplifier board and set a connection password (YS Audio-APP). The Bluetooth-compatible function supports connection to smartphones, tablets, laptops, AUX devices such as MP3 players, and more. It can be connected to both passive and active speakers.

Place the power amplifier board as far away as possible from WiFi signals (e.g., routers). 2. Recommended power supply voltage is DC 5–24V. Exceeding 26V may burn out the chip. 3. Recommended power supply current is 2A or higher. 4. The speaker cable should not be excessively long; ensure it remains within 1 meter. 5. Pay attention to electrostatic protection. Before touching the amplifier board, discharge static electricity from your hands to prevent static damage to the chip. Bluetooth chips are highly sensitive to static electricity. 6. We recommend using speakers rated at 40W or higher to avoid overheating and speaker burnout. Note: Power adapter not included. Hand-delivery available in Amadora area
