The UDH-Dual-B from VocoPro is a portable 900 MHz dual channel UHF Digital Hybrid wireless lavalier and headset microphone system for capturing audio. It can be used in several environments, when two mics are needed, for applications such as lectures, boardrooms, schools, houses of worship, and more.
The UDH-Dual-B runs on two AA alkaline or rechargeable batteries (not included) and is built with an on/off switch, a mini-XLR jack for the mic input, and a volume control knob. In addition, a two color single LED indicates when power is on and flashes solid green for healthy batteries. It blinks red when the batteries are low and require changing.
Finally, an AC power adapter, two headsets, two lavalier mics, a receiver, two rack ears, two antennas, and a 1/4" to 1/4" mic cable are included.
