AD 18 is a small complete digital class d bluetooth amplifier built-in headphone amplifier supports subwoofer output.Connect it to your computer system and use it to drive your earphones with an amplifier or to power your passive speakers(4ohm speaker produces 80Wx2 output power). Advanced matting aluminum housing minimizes interference. Patented SDB sound and +-8 level treble and bass change. Independent headphone amplifier style and advanced DSP innovation makes the unit better.
Amplifier Chip: Using TAS5508C for digital signal DSP processing and Pre-Amp. TAS5342A for digital signal rear-AMP. It will be through LC filter then send out to amplifier output jack.
Digital Receiving Chip: CS8422.It get optical and coaxial signal and all signal transfer.
USB chip: TAS1020B. Supports stereo sound 24bit/96kHz. For far better sound, we use SDPI output instead of internal DAC output style. Strong anti-interference capability and More High-Fidelity.
HP Amplifier Chip: MAX97220A. Dual-OP amplifier: NE5532 with High effectiveness low sound.
Analog/Digital converter IC: CS5341, Accurate to 24 bit 48kHz. Convert AUX signal to digital signal. Then digital signal processing by CS8422
