Instructions:

I. Connect to PC:

42. Insert the USB end of the USB receiver into the PC's USB port. The USB receiver's LED flashes for 1 second, then goes off.

43. Turn on the main unit power switch. The main unit and USB receiver connect automatically; the adapter's LED stays on.

II. Connect to mixer/analog input interface:

44. Insert the USB receiver into a USB power supply interface. The USB receiver's LED flashes for 1 second, then goes off.

45. Use a 3.5mm audio cable: plug one end into the 3.5mm jack at the rear of the USB receiver, and the other end into the mixer's 3.5mm analog signal input interface.

46. (If the target device's interface is XLR, Phoenix terminal, RCA, etc., a corresponding adapter cable is required.)

47. Turn on the main unit power switch. The main unit and USB receiver connect automatically; the adapter's LED stays on.
