For Wireless Audio Connectivity - The Alto Professional Stealth Wireless MKII is a next-gen wireless solution that eliminates the need for up to 200 feet of cabling. With Stealth Wireless MKII, it’s easy to add wireless audio connectivity to any active loudspeaker without compromising audio quality. The system works through walls, floors, and ceilings, providing setup flexibility that far exceeds conventional hard-wired systems. Adding Stealth Wireless MKII to your live sound rig will enable you to skip the long setup and teardown processes required of a wired sound system. This is the ultimate time and money saver. Dual-channel Transmitter - Stealth Wireless MKII includes a single dual-channel transmitter with two removable antennas. The front panel LCD screen conveniently shows the RF frequency, channel number, and AF signal level for each channel. Each system also includes two receivers with slim-line, rugged plastic housings, and dual swiveling hinged antennae. Mono or Stereo Use - Stealth Wireless MKII can be set for mono or stereo use. Two XLR balanced 1/4" TRS combo inputs on the transmitter accommodate the main outputs from nearly any mixing board or console. Each of the receiving units has a single 1/4" TRS output to send the signal to a powered speaker array or a traditional amplifier-and-speaker combo. Each Stealth Wireless MKII package comes with (2) 1/4" TRS to XLR cables so that you can plug them into your system right out of the box. Faster Setup - For sound professionals, setup time, simplicity, and flexibility are of paramount importance. But any reduction in audio quality for the sake of convenience is totally unacceptable. Stealth Wireless MKII delivers exactly what professionals demand—faster setup/teardown, LCD displays for instant visual confirmation of system configuration, and uncompromised audio quality.
