SMSL AD18 HI-FI Audio Stereo Amplifier with Bluetooth 4.2 NFC
USB DSP Full Digital Power Amplifier 2.1 support Bluetooth 4.2/Aux/optical/coaxial inputs 80Wx2
This class d amplifier supports USB coaxial analog bluetooth and two optical inputs
With amplifier output port,3.5mm headphone jack and subwoofer outputs, 80w*2 output power,1.44-inch color screen,the brightness of the display can be adjusted
Customized BT4.2 Bluetooth Module,supports apt-x, easily connect with bluetooth by NFC
The bluetooth amplifier uses TAS5508C+TAS5342A from TI as amplifier chips, DSP technology, built-in SDB sound patented.
Re-designed and updated version AD18
AD18 supports a wide range of inputs, including USB, optical, coaxial, auxiliary, and Bluetooth 4.2. Connect it to your computer and use it to drive your headphones with an amp or to power your passive speakers (4 Ohm speaker produces 80W*2 output). Sophisticated matting aluminium housing reduces interference. Patented SDB sound and +- level treble and bass adjustment. Independent headphone amp design and advanced DSP technology makes the unit more desirable.
Hi-Fi Sound quality, Stable transmission
Bluetooth 4.2 wireless connection and NFC function. This unit uses the most advanced BT 4.2 version, it is more stable and faster in transmission. It supports apt-X (apt-X is a codec, or code/decode algorithm, that packs a digital audio signal into a smaller amount of data transmission bandwidth or data storage than the signal would otherwise occupy. It's a lossy (as opposed to lossless) codec. It's a fixed 4:1 compression ratio so the performance is guaranteed).
AD18 built-in NFC function. Please make sure that the NFC setting on your phone is switched on. AD18 will recognise your phone when close to an NFC area.
Attractive and durable. Compact design
Made from high accuracy CNC advance angle process. Smaller and more convenient.
AD18 uses digital amplifier circuitry. The analogue signal is converted to a digital signal with phase keeping the output signal the 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. The signal will go through the LC filter and then sent to the amplifier output jack.
Digital Receiving Chip
CS8422 mainly acts as a signal converter. It receives a optical and coaxial signal and all signal transfer.
TAS1020B supports 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 Analogue/Digital converter. IC:CS5341, is accurate to 24bit 48kHz. Converts AUX signal to a digital signal. Then the digital signal is processed with CS8422.
Customised BT4.2 Bluetooth Module
Device easily connected with bluetooth by NFC. The device has an external Antenna with a distance range up to 10M or more.
