Bluetooth Audio Receiver Board Wireless HIFI 15Wx2 Stereo Amplifier Module AUX
Features:
This Bluetooth digital amplifier board, use Broadcom Bluetooth Core BEKEN high quality music and compatibility Bluetooth chip, built-in enhanced signal transmission circuit, Bluetooth receiver from the stable continuous sound, built-AEC echo cancellation and noise cancellation ANC circuit, speakerphone ultra-quiet no echo and noise. amplifier IC to make efficient use of pure class D M6008N chip. With ultra-wide bandwidth excellent EMI performance Low-E, the maximum power output 15Wx2, clear and pure treble powerful bass, beautiful appearance, stable, sound quality is excellent and affordable.
Amplifier chip features:
With anti-breaking sound control function, can detect and suppress the input music, voice signal amplitude is too large output signal caused by broken sound and minimizes distortion and noise pulse output signal. In addition, the chip built-in shutdown function enables standby current is minimized, but also integrates the mute function, fade effect, the speaker output over-current protection, over-temperature protection inside the chip and other features.
Using DC power supply interface, Bluetooth stereo dual speaker outputs, paired with a Bluetooth phone or computer, can wirelessly listen to music, but also hands-free phone calls, back-linking function. Support TF card to play, there AUX IN / OUT audio input / output, Max features is switching function / voice prompts. (3.5mm stereo headphone plug audio signal input / output audio amplifiers do have a role).
