UA188 is such a product that developed and finished by YuLong Audio,most senior earphone-fanciers participated in the suggestion of tuning.
These earphone-fanciers have different equipment,environment and personal listening habits.Their suggestion for us is various. We have absorbed the strong points of these suggestion and used our technical experience to carry on the fine-tuning to the product,finally we obtain the more popular voice orientation.
UA188 has a small size, only 165*110*45mm.It uses the refined aluminum shell,so the appearance is high-end.In order to ensure sufficient supply of electricity,we use AC power supply directly,so the driving ability of UA188 is more stronger than the similar small size earphone amplifier which uses an external power or batteries to supply !
In order to ensure the consistency and stability of both the machine's performance and sound effects,UA188 selects the import high-quality components with the fanciers class during the adjustment. Each of the components used must be tested by QC before we begin to produce.
When you press LINE switch,UA188 will work under the pure earphone amplification condition, the USB decoding power supply will be cut off,at this time the USB does not work. The part of earphone amplification will carry on the pure amplification to obtain a better effect.When you press USBINE,UA188 will work under both the USB decoding and the earphone amplification condition,you can connect to the computer to drive the earphone easily.Under either condition, UA188 has a former class output,it can be connected to drive the other audio devices,such as power amplifiers, active speakers and so on.
