Chord XU4-B Quad Bodypack UHF Wireless Microphone System

The Chord XU4-B gives you four channels of UHF wireless microphones in a compact half-width 1U rack receiver. Each channel comes with a bodypack transmitter, a neckband and a lavalier (lapel) mic, so it suits presenters, instructors and vocalists who need to keep their hands free. The receiver uses a true diversity design with dual antennas (aerials) and internal distribution, which helps keep reception steady and cuts down on dropouts across the room.

You get 10 groups of 9 selectable UHF carrier frequencies, covering the UK/EU license-free band and the PMSE licensed duplex gap. That range of options makes it easier to find clear channels when other kit is running nearby. Setup is quick because you can sync settings by infrared from the receiver straight to each transmitter, so there's no fiddling with matching frequencies by hand. A colour TFT display handles the settings menu, and you can set a backlight colour per channel to tell them apart at a glance.

The front panel holds a volume control and indicator LEDs for each channel, plus level metering on the display. Every transmitter has its own LCD showing frequency and battery status, with a backlight you can set to one of six colours. Outputs cover 1, 2 or 4 XLR connections along with a 6.3mm mix output, so you can feed a mixer channel by channel or run a single combined signal. Each transmitter takes 2 x AA batteries, and wireless range runs up to 60m. The set ships with rack-mounting hardware and extension cables so you can front-mount the antennas.
