WR-U4 is a four channel UHF wireless receiver rack with independent and interchangeable modules. It works with the handheld microphone transmitters U-299H and the belt pack transmitters U-299P. Each receiver can operate up to 99 preset frequencies in the UHF local authorized bands. The receiver modules can be removed from the rack and replaced very easily in case of problems. The infrared frequency synchronization system makes easy to synchronize with any new transmitter or receiver quickly without any manual setting. Each receiver features a LCD screen displaying the preset number, the frequency value, the battery life time of the transceiver, and the quality of the RF and AF signals. Four independent XLR balanced outputs corresponding to each output are available plus a mix line output pre-mixing the four channels in one single output.
