C&C F1 Portable Headphone Amp & battery he

CC F1 C&C F1 Portable Headphone Amp & battery head-AMP & High-performance compact battery amp C & C F1 technical characteristics: 1. Professional design, the low-impedance headphones for portable battery amp; 2. With a gain selector switch, to adapt to a wider range; 3. Dedicated sound more perfect sound field compensation, reduce the effects of head; 4. By top op amp, the output impedance is low, control and strong; 5. ALPS volume potentiometer potentiometer using authentic, quality assurance; 6. Using high-performance lithium polymer battery, with full protection; 7. Built-in smart charging circuit voltage; 8. 10000uF pond design, power is more pure (F1). 9. Maximum output power: 120mW +120 mW; 10. Headphone adapter Impedance: 16-300Ω; 11. THD + N (total harmonic distortion plus noise): less than 0.01%; 12. Frequency response :0-100kHz / 1dB; 13. Long life: 100 hours; 14. Pocket size: 68 * 45 * 12-20mm (aluminum housing); 15. Weight (including batteries): 80g; 16. Power :100-240V, 50/60Hz; 5V DC Use instruction: The source (CD, MD, MP3, etc.) signal output, with 3.5-3.5 audio cable to connect to the amp's input jack (IN), press the power switch, then plug the headset output jack (OUT ), adjust the volume, you can enjoy the music. According to the headset impedance, the sensitivity of different, select the appropriate gain switch position, or you can select the sound field expansion compensation, increased sense of hearing. LOW: Low, HI: High, OFF: Off, ON: open. When charging, the power supply into the socket (100-240V universal), DC plug (USB head) into the amp behind the version of USB power jack to charge the battery. Charging indicator light turns red color, full out from the stop. Generally do not have electricity, or long-term hold, to be more than 8 hours charging, normal charging 4-6 hours. Amp internal regulator, charge control circuit that can be filled with the stop, will not overcharge, over discharge, to ensure that the battery life. F1 charging, the circuit will automatically disconnect the amp circuit to improve the charging efficiency, this time not listening to music. Battery is depleted, the power light is dimmed, to go out, prompted charging as soon as possible. There are many protected battery charging without memory effect, can be used with the charge. If you do not have the amp long-term, low-temperature storage should be fully charged, non-air electricity storage.
