Or the user can use a large capacity power bank to power the device, and also use the power cord to connect to this interface (do not use inferior connection wires). Note: This machine needs to be in the 5V/ 2.5A power supply state to work normally at full load. It is forbidden to connect and use this machine when the parameters of the adapter cannot be determined, so as not to damage the equipment.
2. If you can only choose PC USB power supply, in order to reflect the high- quality recording effect of the device, it is recommended that you choose a PC device with a high configuration. Under this power supply state, it is suitable for single-person recording or music appreciation, and it is not recommended to use it under multi-channel/mad music combination.
