Alto Professional STEALTH WIRELESS overview

  • 1Description

The Alto Stealth Wireless Stereo System is a complete, ready-to-use wireless audio system, which consists of a single dual-channel transmitter and two single-channel receivers. Designed for active loudspeakers, it replaces hundreds of feet of audio cable with a reliable wireless connection.

There are up to 16 reliable UHF channels to minimize interference and a manually-set squelch control with three-settings to help optimize performance. The Alto Stealth Wireless Stereo System ships with an assortment of mounting hardware and accessories including three power supplies, two XLR cables, two M10 screws, two machine screws, and two hook-and-loop fasteners.

    Alto Professional STEALTH WIRELESS reviews

    Stealth Wireless Stereo System for Active Loudspeakers is rated 4.5 out of 5 by 6.
    Rated 5 out of 5 by from Awesome System!! I Work for a community college and am in charge of AV support and this product is just amazing!! Excellent price no more running cables and gaffers tape. I Was using the Sennheiser ew 100-ENG G3 to do this but they run more expensive. Pros: - Good Range - Portable - Easy Set-up - NO MORE RUNNING WIRES TO SPEAKERS!! Cons: - Receiver needs to be powered up. (not battery operated like the Sennheiser) - Make sure you don't set to same frequency as Wireless Mic (you may get a little static) Overall excellent product. Recommend it!

    Rated 3 out of 5 by from Kind of meh, does the job I use this for playback on film sets - it's great to remote a powered speaker and not have to worry about 50-100'-plus cable runs. The issue with these is their need for line of sight - recently, just a jib moving in and out of view was enough to disrupt signal momentarily. That, and the fact that this is in the 610-640MHz range makes it a less than ideal buy right now, those days are numbered. I wish Alto would come out with the pro model - it's been coming for almost 2 years now . . .

    Rated 5 out of 5 by from exactly what i wanted I have only used this once, but it performed as I wanted it to. I hooked this up to the booth output from my main DJ mixer and ran it to a satellite speaker on the other side of the property for cocktail hour music. In the past i've had to hook up an iPod to be able to do cocktail hour music that was in a different area than the reception, this has solved that problem!

    Rated 4 out of 5 by from Excellent Product I concocted my 2 speakers in my community center, my mixer was on the 1st floor and the speaker on the 2nd, it worked through the concrete floor.

    Rated 5 out of 5 by from I would buy the product again. Its Works great. One of the adapters didn??t work but I can??t return it because I live on Costa Rica.
