Kind Tips:
▶ For buyers who do not have the ability to replace the op amp,please DO NOT replace the op amp yourself.If necessary,we can help you install it.Product damage caused by opening the shell and replacing the op amp or other components is not covered within the warranty!!!
▶ The Normal version is 2*OPA1612+2*JRC2068DD Version,the sound quality is much better than the decoder of the same configuration/grade, the Upgrade version is 4*OPA1612, the details/dynamic scenes have changed significantly.for 4*OPA1612 Version,there is little noise when the volume is higher than 98%, but there is no problem when the volume is lower than 98 %,and sound better than normal version 2*OPA1612+2*JRC2068DD Version.
▶ For OPA1612 chip, there are two kinds of chips are used randomly, OPA1612AIDR(blue board) and OPA1612AIDRGR(OVII)(green board). They are two different appearances of the same chip OPA1612, with the same parameters and performance, which greatly improves the performance of this DAC to a new level! Please contact us for the TI Official information on OPA1612AIDR and OPA1612AIDRGR if you need it.
▶ This DAC uses DC 5V power supply, if the voltage is too high, it will burn the circuit board,damage caused by high input voltage is not covered by the warranty.
▶ When replacing the op amp, please pay attention to the definition of different pins to avoid reverse insertion, otherwise the circuit board will be burned.The resulting damage is not covered by the warranty!
▶ After 10 minutes of power on, if the Bluetooth search and connection have not been performed, the dac's Bluetooth will be in a dormant state and cannot be searched at this time. If you need to connect Bluetooth, please turn off and turn on the DAC again.
▶ If Bluetooth suddenly cannot be searched, it means that this DAC is connected by other devices. At this time, please check whether it is wrongly connected by other devices. If this device cannot be found, please unplug the antenna and disconnect the connected device,or move this DAC more than 20 meters, and then restart to search.
▶ It is recommended to use a high-quality 5V DC power adapter, preferably a linear power supply. Of course, most 5V DC chargers are suit(PD charger and c to c cable is not suit), but not all of them are supported. If not support, please replace other 5V DC charger adapters like PC/Laptop usb port,power bank,phone changer(including fast phone charger with 5V output).
▶ This dac use 4 pieces dual op amp,they're working at the same time for both RCA and 3.5mm output,not 2 pieces for RCA, 2 pieces for 3.5mm.RCA output and 3.5mm output always working at the same time. If the load is connected at the same time, the output level will be appropriately reduced.
▶ When turning on the power,it will remember the last position of the input selection by default,you needn't to choose the input again.The same goes for Bluetooth, which automatically connects.
▶ This DAC has undergone strict performance and noise testing before leaving the factory. If there is noise during use, it can be solved by adjust the volume below 98%,or replacing a high-quality power supply,or check if there is electromagnetic interference, just change the position slightly.Just contact us if you need help~
▶ At present, there are two random product logos: “AkLIAM” and “Rod Rain Audio”,but we are certain that the product is completely consistent internally. Please contact us If you need to specify the Logo, thank you~
