Instant wireless connectivity for any active loudspeaker.

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.

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.

Setup simplified but for a consequence

By brubber

from Chicago, IL

Comments about Alto Stealth Wireless - Stereo Wireless System for Active Loudspeakers:

I have a DJ business but I'm not impressed. Used it twice and it has failed me in both instances. Even my clients gave me some unwanted comments on how my system sounded horribly. This system is good just for vocals (like wedding ceremonies, etc) and low volume applications. When I cranked up the volume during dancing, sound quality suffers, especially the bass and obvious treble hisses. Also, be always ready to retune the system during unexpected interference. This is a good solution to simplify setup especially during tight and huge venues (max of 200ft distance between TX/RX) but I won't compromise sound quality and hi-fidelity audio. I just sold my wireless system and got back to my conventional xlr cables. Sorry Alto, I'm a fan of your products except for this one.

Not So Stealth. Noise Floor Too High.

Comments about Alto Stealth Wireless - Stereo Wireless System for Active Loudspeakers:

Really disappointed in the high noise floor these bring to the party.

I run a small system; 4 mics, video projector and a computer to a ZED-16FX mixer through a DriveRack PX to four ZXA1-90 speakers primarily for lectures and speaking engagements.

When I run the system with wires, all is well. The speakers do have a noise floor, as do all speakers, especially powered speakers, but it is so low as to be inaudible more than three feet from the speaker. The Stealth Wireless system adds to the noise floor considerably, making the baseline hiss audible even in the center of moderately large hotel meeting rooms. The larger the room the better; but using Stealth, people sitting 20 feet from a speaker have complained about the hiss. I'll keep the Stealth for use in situations where loud hiss is not an issue (music, outdoors, etc.), but for most of my work, I'm back to the wires.

Great idea by Alto, and good execution, but not yet perfect. The high noise floor is likely the trade-off for zero latency, which does work as-advertised. But, with the high noise floor, for me anyway, Stealth will have limited applications.

Wish I had been able to hear a demo of these before I purchased. I may still have purchased Stealth, but I would have known the limitations before doing so.
