The USB uses XMOS XU208, whose sound is mellow and sound resistant. Bluetooth chip chooses CSR8670 supporting more stable and faster data transmission and APTX. Adding coaxial, optical input decoding function, can be connected to TV, DVD, set-top box, etc. Convenient for external audio, can significantly improve the sound effects. Coaxial port with two-way function: When using Bluetooth mode, the coaxial port is Bluetooth signal output (Bluetooth signal spdif out).
When coaxial input, this port is coaxial input decoding (spdif in). With a input switch on the panel, and the corresponding indicator light can show the input state.
It isn't necessary to plug and unplug the USB cable, convenient and lossless. The op amp default 3JRC4580, and can be plugged in and replaced. It uses dual power supply, more dynamic and better resolution. Line out output signal level is 2.1V, better dynamic.Supporting external power supply, can be connected to power bank or other USB ports, such as set-top box, USB port of TV, etc. Convenient for power supply (power supply voltage is 5V, current is greater than 0.5A). Built-in high-fidelity headphone, strong power source with volume control, low frequency response.
Supporting DSD native hard mode when using USB decoding, details, and sound field width are better. USB Support OTG Android mobile Android TV box Apple computer linux don't need the driver (need the external power and set the input mode as USB), We recommend mobile install the APP "haibyMusic"to support DSD format. The sound card supports Windows system (need to install the driver to use), MAC and Linux (do not need to install the driver), as well as mobile device phones, tablets. Power : USB Power(Please note:The voltage must be 5V, if over it the device will be burned).Coaxial, Optical working current: 60mA. USB input working current: 200mA. Headphone power: 130MW / 32? Audio output THD: 0.001%. USB support: PCM44.1K-384K/32Bit, DSD64-DSD256. USB support system: OTG Andriod Mobile. Apple PC, Linux, delphi system don't need the driver. Size: 1109825mm (Not include the connector part). Note: When DAC Only with Optical input (Opt), no matter the switch at Coaxial or optical place the signal is optical signal, Once plug the coaxial cable then you can select the matching decoding way. Please put the selector switch at the "BT "position, then the CNCT indicator will flash quickly. After matching well, the CNCT indicator will flash slowly.
We recommend using the mobile with ATPX function , the sound quality will be much better. If the DAC only with Optical input signal, no matter the selector switch at Coaxial or optical position it just the optical signal, once insert the coaxial cable then have to select the matching input signal, that not the device quality problem, it is just the DAC preferred signal mode. DAC not support DXD format.USB Port to Mobile, need add the external power supply. If the device has a fast forward and no sound problem , that caused by the USB Contact or power supply , just inert the cable again or change USB port is fine. This device Line Out output signal is a little weak, so when connecting it to amplifier should adjust the volume higher. USB sound card can't be identified, If the indicator not glow , the problem caused by USB Poor contact or external power not enough, pls exclude the USB cable problem or power supply voltage is 5V. The device can't be connected to the PC front USB port , it easy cause the papapa noise. Is near 10 meter, the best distance is within 5 meter without the wall or.
