Please note: 1. This package contains the wireless microphone system only. You still need an additional audio device (speaker or amplifier) to output the sound. 2. The volume depends on the output power of the speakers. We recommend not to use this microphone for speakers under 15 watts. How do I avoid interference? 1. Do not use the microphone too tight to the receiver to avoid noise interference. 2. Keep the receiver away from metal or digital devices (such as computers, mobile phones, etc.) to avoid possible sources of interference. 3. We recommend using a windshield foam cover to achieve a better vocal experience.     How to use: 1. Connect the receiver to a socket and turn it on. 2. Connect the output socket of the receiver and the input socket of the amplifier or active speaker with the audio cable (use an adapter from 6.35 mm to 3.5 mm if your speaker has a 3.5 mm socket). 3. Connect TV / PC / DVD / VOD or other audio devices to the amplifier or active speaker to play background noise. 4. Connect your external speaker to the amplifier with an audio cable to output sound (Please ignore these steps when using an active speaker). 5. Insert 2 AA batteries into the microphone. Turn on the microphone and enjoy singing songs.
