Warm tips: 1. Bluetooth input is prior to USB input, if you want USB input please make sure Bluetooth input is disconnected. 2. USB input doesn't support U-disk or Hard-disk, can connect USB interface of computer or mobile phones (Android system needs OTG cable and IOS system needs camera kit, please prepare by yourself). 3. This is a preamp but NOT a amplifier or a phono preamp, CAN'T be used for turntables or passive speakers. The main purpose of L200 is to act as a buffer to sweet the sound.
