SMSL AD18 80W2 Bluetooth 4.2 HIFI USB DSP Digital Decoding Power Amplifier Review

AD 18 is a multi-functional digital power amplifier with headphone amplifier. Up to six kinds of
input including USB, coaxial, analog, bluetooth and two optical jacks(round and
square).Customized BT4.2 Bluetooth module, device easily connect with bluetooth by NFC. Using
TAS5508C+TAS5342A from TI. Headphone amplifier adopts independent IC. Using advanced DSP
technology, with 1.44-inch color screen and remote control. Built-in SDB sound patented belongs
to S.M.S.L.

Amplifier Chip: Using 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.
Digital Receiving Chip:CS8422. It receive optical and coaxial signal and all signal transfer.
USB chip: VT1620A. Support stereo sound 16bit/24bit and sampling rate up to 192kHz.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. Dual-OP amplifier: NE5532 with High efficiency low noise.
Analog/Digital convertor IC: CS5341, Accurate to 24 bit 48kHz.Convert AUX signal to digital signal.
Then digital signal processing by CS8422
