Wireless Stereo o Board 100Wx2 Bluetooth Receiver Amplifier Module

1. Bluetooth 5.0 version for improved transmission efficiency and extended range. 2. Large heat sink ensures efficient thermal dissipation. 3. Volume control potentiometer with on/off switch for easy operation. Suitable for DIY speaker projects. If using a metal enclosure, ensure proper Bluetooth antenna placement. 4. Copper DC power connector designed for high-current applications with minimal heat generation. 5. Four 470µF capacitors provide stable power storage and consistent power delivery, supporting high-fidelity audio performance. 6. DC power input with cable allows flexible connection to compatible power sources. Input Voltage Range: 5–24V (compatible with 9V, 12V, 15V, 18V, and 24V adapters; higher voltage recommended for increased output power). Power Output Specifications: - At 12V: 24W + 24W into 8Ω; 40W + 40W into 4Ω - At 15V: 32W + 32W into 8Ω; >60W + >60W into 4Ω - At 19V: 64W + 64W into 8Ω; >80W + >80W into 4Ω - At 24V: 72W + 72W into 8Ω; >100W + >100W into 4Ω Product Name: HIFI Bluetooth Digital Power Amplifier Board with Filter Model: ZK-1002L Chip Solution: Domestic IC Filter Included: Yes Compatible Speaker Impedance: 4Ω–8Ω Speaker Power Range: 50W–300W per channel Channels: Stereo (Left/Right) Bluetooth Version: 5.0 Bluetooth Range: Up to 15 meters (line-of-sight) Protection Features: Overheating protection, short-circuit protection Color: Black Material: Metal + PC Package Contents: - 1 × Bluetooth 5.0 Digital Amplifier Board - 1 × Enclosure - 1 × Screwdriver - 1 × Power Cord Usage Notes: - The board’s power switch functions as a standby switch. When off, the unit enters low-power standby mode. - To fully disconnect power, unplug the DC power supply. - Maximum output power depends on sufficient audio input signal, adequate supply voltage, and current capacity. - Higher supply voltage increases available output power. - Output power varies with speaker impedance: for a given voltage and current, higher impedance results in lower output power. Note: Color representation may vary slightly due to lighting conditions and screen settings. Dimensions are subject to a tolerance of ±1–3 cm.
