This package includes everything you need to add professional quality audio to your video productions. There are two transmitters and one receiver. The transmitters have two plugs, one for microphones, and one for line-input, so you can transmit just about anything. The receiver has two antennas, and two plugs, one for output and one for a headset so you can monitor the audio in real-time.
What I like most about this set is the professional attention to detail. All the units can be run on either 2-AA batteries, or by USB power. All the connections have locking screws so you don't have to worry about the cables getting pulled out by mistake.
In addition to the transmitters and the receiver, the kit also includes a pair of high quality lavalier microphiones with two types of windscreens, foam and fur. it also includes belt clips and several other cables including an XLR adapter for connecting to pro-grade gear.
Everything comes in a high quality canvas bag and it comes with an easy to follow manual that explains how to change the channels, and adjust the gain. I'm not a big fan of most user manuals, but this one was easy to follow.
I recorded a short video demonstrating the kit in action... I hope you find it useful. Check it out and feel free to ask questions in the comments.
