68W*4 LM3886 Amplifier Board HiFi Amp Board Assembled without Heat Sink For Car DC 12V Power Supply

68W*4 LM3886 Amplifier Board HiFi Amp Board Assembled without Heat Sink For Car DC 12V Power Supply

Features:
- 4-channel: 68W*4.
- Powered by vehicle DC 12V power supply.
- LM3886 is a well-known high-performance audio power amplifier integrated circuit. The maximum output power can reach 68W, the sound is accurate, noise and distortion are quite low, and the protection function is relatively complete, and the performance is stable. LM3886 is a configuration of high and medium power HIFI audio amplifier and high fidelity active monitor speaker amplifier circuit.
- This power amplifier board takes LM3886TF as the core and adds a step-up transformer conversion circuit. Just use DC 12-14 to make it work. It can be used in a car to works as a HiFi car power amplifier. Four independent amplification, and with a complete output protection circuit, midpoint detection circuit, switch delay circuit. It outperforms ordinary car power amps in tone and performance.
- Component Materials: Professional high-power single to double-boost circuit, imported HiFi coupling capacitors, German capacitors, C1237+ imported relay for protection circuits, switch machine without impact, pure sound quality, brand new imported LM3886TF. Imported output protection relay.
- The four channels of LM3886 are independently amplified and output with protection function. Imported relay and imported LM3886TF chip are used for output protection circuit.
- Professional high-power single to double boost circuit, full power.
