S.M.S.L AD18 Audio HiFi Stereo Amplifier with Bluetooth 4.2 Supports Apt-X,USB D

Product 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.

【Digital Input】The SMSL AD18 has 6 input methods, USB, coaxial, analog, Bluetooth and two optical fibers, using two different chips for SPDIF and USB input. The USB comes from Texas Instruments’ TAS1020B. The chip fully supports 24bit/96khz, and any excess will be automatically downsampled. SPDIF uses Cirrus Logic’s CS8422. The chip can decode files up to 24bit/192khz, but can only decode up to 96kh on the AD18.
【Bluetooth and NFC】The Class D amplifier allows you to Bluetooth BT4.2 Bluetooth input, Bluetooth supports apt-X, and easily connects Bluetooth via NFC, providing higher quality wireless playback for compatible , tablets and Android smartphones.
【Two Independent Circuits】The S.MS.L ad18 bluetooth amp has two independent circuits, one for speakers and one for headphone output. It also has a subwoofer active subwoofer output, 80Wx2 amplifier output, with amplifier output, which can provide unparalleled stereo audio for speakers. 3.5mm headphone jack, the headphone amplifier
【Bass and Treble Control】SMSL Audio Stereo Amplifier This all-in-one amplifier is also equipped with a digital equalizer with multiple functions (bass tuning, treble, etc.), built-in SMSL patented sound effect SDB, SDB can effectively improve the sound restoration, while dynamically adjusting the high and low sounds according to the current music signal.
【SMSL AD18 chip】Full digital amplifier is part of the new generation of FDA all-digital amplifiers. It uses high-tech TAS5508C and TAS5342 chips using Texas Instruments (TI) digital pure path technology. The amplifier has the characteristics of “all-digital”, compact design, high sound quality and high resolution, bringing a wonderful experience to music lovers.
