1. Audio solutions use BB PCM2704 ( USB DAC ) /OPA2134 ( LINE OUT ) /MAX9722 ( 130mW+130mW AMP ) building, with its excellent industrial design, thin thickness within the control of 9.54mm ( and iphone4s be roughly the same ), becoming the most thin decoding amp integrated machine in the market. The design of the popular tune, sound mellow song. The mainstream fashion appearance, easy to carry, is that the young generation is necessary headset HIFI game player peripheral products.
2.U-SKIN amp and decoding mode conversion using the relay the amp when listening to music ,while using USB decoding to listen songs , unplug the INPUT audio cable, the relay will automatically to go to listen to the sound of the computer inside player and music using the USB DAC.
3.decoding part of the chip module equipped with PCM2704 OPA2134, PCM2704 support 16BIT/48KHZ see the value of just a standard value, but this decoder chip is very mature, very stable work, recognition speed quickly. USB digital signal can be accurately decoded analog signal output using the classic op-amp chip 2134, the popularity of the chip believe many enthusiasts have heard, Features is warm sound, Naiting and detail is extremely rich. 2134 also served as a preamp, amp part is enlarged by 9722. 9722 is a professional amplifier chip, full thrust, tie circuit optimization can achieve 130mW 130mW of output power, so deal with 16-300 ohm headphones also easier, although the force, but the sound engineers carefully debugging under extremely delicate, very strong sense of hierarchy.
4.official statement said 40 hours of battery life, go shopping trust enough to use. The charge is 2 hours can be filled with, very fast, built-in intelligent charging protection chip, prevent overcharge or not full. The charging of STATE lights, STATE lights charged.
