Preparation for a gig or video filming becomes much easier 

• A battery-powered system provides the greatest convenience for outdoor use.
• Even the most generic AA battery(*2) for the back-pack transmitter and AAA ones(*2) for the receiver can last for 4 hours.
• The system is pre-paired. Just remove from the box, plug into a camera/digital recorder via the included adapter or hook up directly with a PA speaker, amplifier, mixer (any device that allows 1/4" input) for a live event. 
• For web conferencing through smartphones or computers.

Great features for outdoor use

• The easy-to-read transmitter LCD display shows battery life and the current frequency channel. 
• The receiver indicator conveys info of power and wireless connection (solid red - paired; blinking green- power runs low and failed to pair). 
• Both features enable your quick response for changing fresh batteries or new frequency, to eliminate cutout or dropout.
• UHF (Ultra High Frequency) is more penetrable and powerful, therefore a better choice for using in built-up areas. The wireless range is 45-60 feet even in the face of obstacles. 
• 20 frequency channels ensure conflict-free performance in less than perfect environment. 

What's the point of 20 channel

1. When experiencing interference, click the button on top of the transmitter to find the best-suited channel. 
2. Multiple sets of K037B can be utilized concurrently for a large group interview (will need multiple input jacks on speaker or mixer to plug in receivers).
