1>>>High-performance Dac & USB Decoding Chip
Equipped with the powerful and proven ESS ES9038Q2M and XU208 chip, the DS400 headphone amps is capable of decoding Up to 768kHz/32 bit and DSD64-DSD512, Its memory is twice as high as U8, and its computing speed reaches a terrifying 1000MIPS, which is twice as fast as U8’s 500MIPS.The DS400 ‘s dual crystal oscillators ensure that any digital audio signals being fed into the DAC are exactly correct for further enhanced sound quality.
2>>>Support full Hi-res wireless Bluetooth format
Can easily handle any low or high impedance headphones. For a total power output of up to 140.5mW under a 32Ω load, and up to 140.5mW at 600Ω, the DS400 desktop amplifier. With volume adjustment, DS400 portable headphone amplifier allows you to smoothly adjust the volume at extremely fine increments without any undesirable noise nor with any channel imbalances.
3>>>Type-C OTG input
Only one line（USB OTG line) is required to complete all the inputs, no additional lines are required. The ESS chip in the DS400 directly converts any USB audio input to digital signals output , allowing you to connect to speaker systems, amplifiers, or other external decoders.
Note: The input cannot be completed if the USB line does not have OTG function, such as the original data line of iphone.
4>>>Variety of Outputs
Supports 3.5mm single-ended and a 4.4mm balanced headphone out/RCA line-out outputs, ,with optical and coaxial inputs supporting up to PCM44.1-192kHz,DSD64 outputs, so the DS400 portable headphone dac compatible with various OSes like Android/iOS/Windows7/10, you could use it connect with your phone/computer/player.
5>>>Unbelievably Low Noise Floor
Optimized active low-pass and BASS circuit designs ensure lower noise floor in any situation. Such as power supply module. the DS400 implements overvoltage protection (OVP) and a double-filter circuit to ensure power supply stability, while the digital and analog audio circuits each get their own power supply to greatly reduce crosstalk.– this is true high-fidelity sound.
