ZK-1002T AUX+Bluetooth-Compatible Amplifier Board HIFI 2.0 Channel 100Wx2 Audio Module Stereo Subwoofer Speaker Treble Bass Accessory Feature: Bluetooth-compatible audio amplifier module 2.0 dual-channel stereo output, maximum output power 2X100W AUX and Bluetooth-compatible audio input mode, two in one power amplifier board. Bluetooth-compatible 5.0, transmission efficiency is higher, transmission distance is longer Imported CS8673E power amplifier chip, TPA3116D2 with AM interference suppression function; Output filter, HIFI sound quality, low requirements on the speaker With short circuit protection and over current, over heat, anti-reverse connection protection, to prevent comprehensive failure. When an overload occurs, the device reports the failure to the processor to protect itself from damage Use copper DC connector and fence terminal. Can withstand large current, do not heat, do not damage the wire. Adopt professional 36MM*25MM*10MM large area heat sink. Close to the shell of copper heat dissipation, heat dissipation area doubled, to ensure the full power of the product high-performance operation. With bass, treble, subwoofer frequency and volume control, easily adjust the volume, enjoy the music you want to sound.
