Product Description

Sabaj A4 is a small full digital class d bluetooth amplifier,with Clear, articulate hi-fi sound quality 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. Compact size makes  it  easy for this  amp to fit almost anywhere. 
Independent headphone amplifier design and advanced DSP technology makes the unit more desirable.
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:TAS1020B. Supports stereo sound 24bit/96kHz.For much better sound, we use I2S 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 converter IC :CS5341,Accurate to 24 bit 48kHz.Convert AUX signal to digital signal. Then digital signal processing by CS8422
