UR-270D + 2x UD-222, band A (522-586 MHz)

Relacart UR-270D + UD-222 522-586MHz - dual-channel UHF wireless system with two gooseneck conference microphones

Professional conference microphones with no cables on the table and no holes drilled in desks. The Relacart UR-270D + UD-222 is a dual-channel UHF system operating in the 522-586MHz band, consisting of a UR-270D receiver in a metal 1U rack housing and two UD-222 wireless gooseneck conference microphones. Each microphone features a stable metal base, a 420mm gooseneck, an OLED display and a silent touch switch that lets you turn the microphone on and off without clicks audible through the sound system. With no cables, the room can be set up and rearranged quickly. It is designed for AV integrators equipping conference rooms, council chambers, public offices and institutions, and lecture halls.

The UD-222 microphones offer volume adjustment from -10 to +10dB and a low-cut filter that attenuates frequencies below 200Hz, while two AA batteries provide approx. 9 hours of operation. The receiver features an automatic frequency scan button (AFS), infrared synchronisation, a Feedback Killer and a MagicEQ parametric equaliser. The LCD display with a Polish-language menu shows RF and AF levels, signal strength and battery status, while the TCP/IP protocol allows the receiver to be controlled over the network. The range reaches 80m in open space.
