-1002L MINI Bluetooth 5.0 DC 5-24V Wireless o Digital Power Amplifier Stereo Board 100Wx2 Bluetooth version 5.0 provides higher transmission efficiency and a stable connection with a transmission distance of up to 15 meters without obstruction. Equipped with an efficient heatsink for optimal heat dissipation. Volume control via potentiometer with an on/off switch for easy operation, suitable for DIY speaker projects. If using a metal enclosure, ensure the Bluetooth antenna is properly extended. Features a copper DC connector designed to handle high current with minimal heat generation. Incorporates four 470uF capacitors to ensure stable power storage and consistent power delivery, supporting high-quality o performance. DC power input with cable allows compatibility with standard power supplies. Direct wiring is possible even without a DC adapter or battery. Operating Voltage: 5-24V (Compatible with 9V, 12V, 15V, 18V, 24V adapters; higher voltage recommended for better performance) Power Output: - 12V: 24W + 24W @ 8 ohm, 40W + 40W @ 4 ohm - 15V: 32W + 32W @ 8 ohm, 60W + 60W @ 4 ohm - 19V: 64W + 64W @ 8 ohm, 80W + 80W @ 4 ohm - 24V: 72W + 72W @ 8 ohm, 100W + 100W @ 4 ohm Product Name: HIFI Bluetooth Digital Power Amplifier Board with Filter Model: -1002L Chip Solution: Domestic Built-in Filter: Yes Compatible Speakers: 50W-300W, 4 ohm to 8 ohm Channels: Stereo (Left and Right) Bluetooth Version: 5.0 Bluetooth Range: 15 meters (unobstructed) Protection Features: Overheating protection, short circuit protection Color: Black Material: Metal + PCB Package Includes: 1 x Bluetooth 5.0 Digital Amplifier Board 1 x Shell 1 x Screwdriver 1 x Power Cord Note: The power switch on the board acts as a standby switch. When turned off, the unit enters a low-power standby mode. To completely disconnect power, remove the DC plug. For optimal performance, ensure sufficient input signal and adequate power supply voltage and current. Higher supply voltage results in increased output power. Output power varies depending on speaker impedance. With sufficient power supply, higher impedance speakers will produce relatively lower output power. The package includes only the items listed. Other accessories or products are not included. Note: Lighting and display differences may cause slight variations in the color of the item compared to the image. Measurement error is allowed within +/- 1-3 cm.
