C&C XO2 CC XO 2 Portable Headphone AMP & 2011 version

C & C XO2 Features:
1. Professional design, suitable for driving low-impedance headphones high school;
2. With high and low impedance selector switch, gain selector switch, to adapt to a wider range;
3. No channel input and output coupling capacitor, a wider frequency response;
4. Special compensation for more perfect sound, low dive + sound field expansion of compensation to close the compensation, is a wide adaptability of high-fidelity headphone amplifier;
5. In parallel with multiple power tube output stage, the output impedance is low, control and strong. High-impedance state to start boost circuit, the output distortion with high voltage and high impedance headphonesto meet the demand-driven;
6. The volume of imported high-quality potentiometer fever potential, ensure sound quality;
7. High-performance lithium polymer battery, with full protection;
8. Built-in smart charging circuit voltage can be while listening to music while charging;
9. Large reservoirs + and more ultra-low resistance solid capacitor decoupling design, power is more pure.
10. Maximum output power: 1000mW +1000 mW;
11. Headphone Adapter Impedance: 8-600Ω;

C & C XO2 and C & C XO +  differences:

1.C & C XO2 is the development of XO and XO + 5 years sales experience, and feedback from many users on the basis of the proposed redesign of the circuit, adjust the structure, optimize the layout, each has improved significantly. 
2. High barrier maximum output slew distortion, there is a substantial increase compared with XO +, single-ended output voltage swing close to 24V, 300-600 European headset more easily drive to reach a new height of portable battery amp. 
3. Before the selection of super-class amplifier, compared with the XO +, sound quality, more excellent performance, lower noise floor, greater resistance to RF interference. 
4. Driven by four imported high-level constant current source, precise control of 12 medium-power tube output array, the low resistance before the high-impedance mode file mode with high-performance, all the load adaptive, dynamic performance has significantly improved . 
5. The new design of capacitor array composed of large reservoirs around the stage, the sound is more pure, high and low frequency extension wider. Large discrete capacitors within a total of 20, including solid-state capacitors 6, 1000uF16V fever, low resistance electrolytic 4, Siemens ... film capacitors 6, the total component count over 200. 
6. The new design of the output DC, short circuit, over current protection circuit, such as multiple, full protection of headphones and amp, better durability, the failure rate lower. 
7. Specially tailored, high quality, high-capacity lithium polymer battery pack, capacity increased by 40%, no signal or low battery power-saving features that make life longer and longer battery life. Life time: 70 hours low resistance profile, high block 18 hours. 
8. High and low impedance headphones choice, four gain, two kinds of compensation, intelligent charging protection, 2 * 2-color indicator light, audio channel without coupling capacitors, etc. XO + classic design retained. 
XO2 the front panel lights, left for the green / red color, the right side of the blue / red color, indicating different states, see below described in detail. 
There XO2 unified certificate number.
