Digital Bluetooth Amplifier 2x20W

Description: The digital Bluetooth amplifier provides an excellent solution for your audio projects with a power of 2x20W. Equipped with Bluetooth 5.0, it enables a stable connection over a distance of up to 15 meters. Ideal for use with Raspberry Pi or mobile phones, it transforms any environment into a sound room with excellent stereo sound quality. Additionally, the amplifier offers protection against reverse currents, short circuits and static electricity, ensuring its longevity and reliability.

Notes:

• Place the amplifier board as far away as possible from WIFI signal sources to avoid interference.
• An operating voltage of 5-24VDC is recommended. Voltages above 26V can damage the chip.
• The input voltage must not exceed 16V when using 4Ω speakers and 24V when using 8Ω speakers.
• A current of at least 2A is recommended for power supply.
• Speaker cables should not be longer than 1m.
• Pay attention to electrostatic discharge, as the Bluetooth chip is very sensitive to static electricity.
• Use speakers with more than 40W power to avoid damage.
• At low supply voltage and high output power, noise may occur. Reducing the volume or increasing the supply voltage can remedy this.
