ALTO Stealth Wireless
The easy-to-use Stealth Wireless system from Alto Professional replaces hundreds of feet of audio cable with a reliable
wireless connection. Compatible with all active loudspeakers, as well as traditional passive speaker/amplifier setups,
this expandable two-channel system delivers interference-free sound.
Save Time. Save Money.
Enjoy faster setups, quicker teardowns, and eliminate complicated or unsightly cable runs, regardless of the venue.
The Stealth Wireless system quickly creates a robust, invisible connection from the output of your mixer or DJ controller
to the inputs of your active loudspeakers. There’s no need to snake, secure, or hide any cabling during set up. After the
show, simply disconnect the system and be on your way—no more tedious cable coiling at the end of the night.
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.
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.
