The 4-Channel Wireless Headset/Lavalier Microphone System from VocoPro includes two UDH-DUAL-B systems pre-installed in a custom gig bag to give you a 4-channel system. Everything needed to set up is right there in the bag; you just need to connect the included XLR snake cables to your sound system and get started. This system includes two dual receivers, four bodypack transmitters, four headset microphones, four lavalier microphones, two power adapters, and two 1/4" patch cables.
This 4-channel wireless system combines digital signal processing technology with a traditional analog UHF transmitter. It is suitable for places that do not have a dedicated sound technician like schools, houses of worship, and more, or production rental companies.
Each of the transmitter backpack 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 dual-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.
