VocoPro UHF3200 Wireless Handheld Microphone System; Two road ready mics for home karaoke or DJs on the road! Operating on the UHF band, the UHF3200 offers a clearer signal and interference free operation with this less crowded frequency band. Each mic channel uses a separate volume control, independent 1/4 inch outputs for each mic that can be run into two separate mixer channels and a single 1/4 inch output that sends both channels to a single source so using the mixed output channel you can save on mixer channels or plug directly into your home karaoke player. Refer the user manul, page 13, for troble shooting steps.
