The DNA RV-4 is a professional wireless microphone kit consisting of four handheld microphones and a radio receiver that transmits audio signals to the sound system. This kit is the perfect solution for bands, vocal groups and event companies. It is ideal for weddings during general parties, karaoke, on stage during concerts and various performances, as well as during conferences, author meetings and various cultural events.

Each wireless microphone is powered by two AA batteries. The centre of the handle features a power switch, an infrared receiver and an easy-to-read LCD display showing the transmitter frequency and battery level. There is also a high and low frequency switch that allows subtle adjustments to be made to the timbre of the sound picked up by the microphone.

The UHF receiver has 2 XLR output channels (A and B) and a 1/4 jack output. There are 4 separate control panels on the front for individual microphones. These can be used to pair the units together by sending the appropriate transmitter frequency to a specific panel via infrared. The microphones are ready for use and we can control their volume and channel functions via the receiver. The wide frequency range and high data rate allow the microphones to operate without interference.

The DNR RV-4 is an excellent wireless audio system widely used in stage technology. It is lightweight, mobile and easy to use, and it is powerful too, with two batteries providing up to 8 hours of operation! When considering which wireless microphone to choose, it's definitely worth thinking about a complete solution and paying attention to the DNA RV-4.
