Enjoy creating a new wireless remote audio project with this all-in-one, easy to use 3.0 Bluetooth 2.1 channel three piece amplifier board with bass, treble, and subwoofer volume controls. It delivers 50W into stereo channels and an additional 100W into a mono subwoofer channel for making a big sounding remote boom box, portable speaker, or even a mobile power amp.
2.1 Amplifier 50W x 50W x 100W with Built-In Bluetooth 3.0 Backlit LCD Screen, and IR Remote
Make your own 2.1 multimedia wireless Bluetooth amplifier or portable speaker with this 2 x 50W + 100W amplifier board. The board accepts 9 to 26 VDC which makes it perfect for making home or mobile audio projects. Use a 120-055 24V DC power supply for highest output wattage. Make your audio project truly portable by adding three to five 18650 Li-Ion batteries. The built-in 150 Hz low pass filter helps eliminate extra crossover components when building an amplified 2.1 3.0 Bluetooth speaker. The 2.1 design also saves you money, eliminating the need for and active subwoofer.
The IR remote, digital display, and 3.0 Bluetooth sets this 2.1 amplifier apart from other pre-assembled amp board kits. One small board incorporates a NE55322 3.0 Bluetooth module and a 2.1 TPA3116D2 chipset amplifier with a connected PT2313 digital display and preamp tone control powered by one 9 to 26V DC supply. This saves you time and money eliminating the need for extra power supplies. Not only does the IR remote control all the sound functions like a smartphone, it also selects the audio input mode and turns the amp board on/off. The digital display keeps you informed of what mode you're in, mute on/off, loudness on/off, and volume level for master, bass, treble, and sub.
