When the summer temperature is high, pay attention to heat dissipation to prevent hot hands!   Normal version: working in Class A and Class B;   Special Edition: Maximum output current 1A peak-to-peak one channel, 400% higher than MG2; (Note that the peak current here only supports instantaneous value, does not support such a large current for a long time)   Normal version: Maximum output current 0.5A peak-to-peak one channel, 200% higher than MG2; (Note that the peak current here only supports instantaneous value, does not support such a large current for a long time)   Special Edition: Battery capacity is 10200mA/h (three Panasonic 18650 lithium battery 3.7V/3600mA/h) with balanced charging board;   Normal version: battery capacity is 10200mA / h (three Panasonic 18650 lithium battery 3.7V / 3600mA / h) with balanced charging board;   Both the special edition and the normal edition are equipped with a headphone protection circuit and a shutdown earphone protection circuit;

 

 

Support: single-ended input balanced output, support balanced input single-ended output, support balanced input single-ended output;   Please lower the gain when using balanced output! Single-ended and balanced can be switched through the switch on the front panel.

The charging indicator is on the charger like the MG2, full of green light; Warranty service is the same as MG2!   Note : 1: In the season when static electricity is easy to occur, do not open the IC of the box touch circuit board at will;   2: If the earphone is a low-resistance and high-sensitivity earphone, and the magic is changed to balance with the MG3, for a better experience, please do not adjust to the maximum gain, because the gain reaches 10 times of the horror, for the low There is a slight noise floor in headphones that are sensitive to high sensitivity! The minimum gain can be used as much as possible under the condition that the gain can be satisfied, so that there is a better listening experience.   3: The balanced single-ended switch on the front panel is only the signal for switching the input. It is not the output of the switch. The balance of the output and the single-ended can be used at will, as long as the connection is correct.   Product List:   1pcs  headphone amp
