Description

AD 18 is a small full digital class d bluetooth amplifier built-in headphone amplifier supports subwoofer output.Connect it to your computer and use it to drive your headphones with an amplifier or to power your passive speakers(4ohm speaker produces 80Wx2 output power).Sophisticated matting aluminum housing reduces interference. Patented SDB sound and +-8 level treble and bass adjustment. Independent headphone amplifier design and advanced DSP technology makes the unit more desirable.


CS8422 it mainly act as a signal convertor. It receive optical and coaxial signal and all signal transfer.	TAS1020B support stereo sound 16bit/24bit and sampling rate up to 96kHz. For much better sound, we use SDPI output instead of internal DAC output design. Strong/anti-interference ability and more high-fidelity. HP Amplifier Chip:MAX97220A analog/digital convertor IC:CS5341,Accurate to 24 bit 48kHz. Convert AUX signal to digital signal. Then digital signal processing by CS8422.	Customized BT4.2 Bluetooth Module Device easily connect with bluetooth by NFC. External Antenna Distance range up to 10M or more


AD18 uses digital amplify circuit. All analog signal convert to digital signal to make PHASE of input and output signal keep same. Phase shift is zero. Strong anti-interference ability. High efficiency up to 90%.	TAS5508C for digital signal DSP processing and Pre-Amp.	TAS5342A for digital signal rear-AMP. It will be through LC filter and then send to amplifier output jack.
