Airwave is the best kept secret in wireless mics today.  This is a brand that we've been watching and using for years - when you don't need top-dollar, high-end wireless, these Airwave mic's provide an exceptional value and quality at a reasonable price. 

By bunding 2 channels of wireless together into one rack unit, Airwave saves on cost and complexity.  Smaller installations LOVE the fact that you can simple use (1) XLR output for both microphones when you're short on inputs.

All of the microphones sound good and have quality that is comparable to mid-level microphones from the major players.   When we have gotten these for customers, the feedback we get is that they love the mics, and they are comparable to systems that cost almost twice as much! 

You'll notice that the receivers have a battery level and RF/AF indicator and IR sync.  Other wireless systems in this price range have none of that.

It's not a $3000/channel wireless system, but what it is, is a tremendous value for many churches, bands, installations, corporate AV, and more!

This package features (2) lavalier microphones.

If using up to 2 units (up to 4 channels) the wireless handheld microphone system does not require an antenna combiner under normal conditions.  If using 3 to 5 units (6 to 10 channels) the use of an approved antenna combiner is highly recommended. The official Antenna distribution partner of Airwave Technologies is RF Venue.   They are without question, the leaders of antenna distribution.
