Review: Works Beautifully!!!! - This unit works better than expected and adds versatility to any DJ/KJ setup. It has good range with new batteries but you can hear the difference as the batteries ware. I recommend this unit to anyone. Review: Works as intended but there are issues with the hand mics dropping out. - The unit works very well as advertised with an occasional glitch on handmics that dropout depending on where the user is holding it. I purchased it for a class where the instructor uses a head mic and they pass around the other two microphones to the class to get any comments or remarks and it does as it is supposed to do except, like I said, the hand mics might drop out. Update: We. have used the unit for 3 classes and are having continuing issues with the 2 hand mics. GTD has replaced the 2 hand mics but we continue have drop out issues. I am trying to find frequencies that work better hoping that that will solve the issue. I will add more as we try to work through this. Also, know the dropout issues do not occur with the head mics and body packs as they have use an external antenna. Please know that GTD has been working with me to resolve these issues, for which I am very grateful. ## Features - 100 Selectable frequencies on each mic, Multiple sets can be worked at the same time - Automatic transmitter setup, the channel of the transmitter and receiver can easily synchronize - Automatic frequency scanning to find and set the best available channel - Range: up to 300 Feets ( 100 meters ), Frequency: UHF 520MHz - 580MHz ( Selectable ) - Four XLR individual outputs and one 1/4" Mixed output.
