Everything You Need
This complete, ready-to-use system contains a stereo (2-channel) transmitter, plus two single-channel receivers. The transmitter is equipped with XLR+1 4 combo inputs to accommodate nearly any type of mixer or other audio source. Each receiver provides a single XLR output. Two XLR cables are included. The Stealth Wireless also includes an assortment of mounting hardware, used to secure the receivers in place.

Simple Setup
First, Connect the transmitter. Plug the main outputs of your mixer or DJ controller into the Stealth Wireless transmitter, using either the XLR or 1 4 inputs.

Next, Connect the receivers. Take the XLR output on the Stealth Wireless Receiver and connect it to the input of your active loudspeaker, or to the input of your amplifier speaker combination. Repeat this step for the second receiver.

Turn the transmitter on first, and then the receivers. It’s that easy. Select any one of the 16 reliable UHF channels to minimize interference. The squelch control can be manually set to one of three levels for optimal performance. As your needs change, you can add more receivers to your system with the Stealth Wireless Expansion Pack.
