Setting up
The system includes two handheld transmitters and a USB receiver. Connect the USB type A plug to a 5V 1000mA USB port (power adaptor or power bank). Note that the USB port is for power only; audio is not transmitted via USB. If you need to connect a USB stick, you can use the USB type A socket on the rear of the receiver.
Operation
Before connecting, turn down the volume on your mixer or amplifier to prevent loud noises. Connect the 3.5mm plug to the receiver and the 6.3mm plug to the mixer/amplifier input. Insert 2x AA alkaline batteries into the microphones, ensuring correct polarity. Move the switch to 'on'. If the LED is lit constantly, replace the batteries. Use the 'mute' position on the switch to silence the microphone while keeping the signal active.
