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 replacing the op amp or other component is not covered within the warranty
▶ The default is 2*OPA1612+2*JRC2068DD Version,the sound has been greatly improved, 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 default 2*OPA1612+2*JRC2068DD Version,please contact us if you need it.
▶ For OPA1612 chip, there are two kinds of chips are used randomly, OPA1612AIDR and OPA1612AIDRGR(OVII). Their performance is very outstanding, which greatly improves the performance of this DAC and the cost performance of this DAC to a new level
▶ This DAC uses DC 5V power supply, if the voltage is too high, it will burn the circuit board.
▶ When replacing the operational amplifier, please pay attention to the definition of different pins to avoid reverse insertion, otherwise the circuit board will be burned.
▶ After 10 minutes of power on, if the Bluetooth search and connection have not been performed, the dac&x27;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.
▶ 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 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.
▶ 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~
