Alto

Description

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.

Dependable?

I was quite excited about this product and spoke very highly of it. I heard other users which had purchased the system when it first was released were also impressed. So we got a system. The day it came in, setup and tested for Range and was surprized. I too encountered the human eliment, when someone walked between the Trans & Receiver site line the Audio would be interupted. At another loaction the Transmitter was positioned high on a balcony with the receivers velcro'd high on the speakers and it worked properly during the rehearsals but during the scheduled event the Audio started dropping out to one of the receivers. That same day in the afternoon we changed to a different CH and the other receiver started dropping out. We are going to try other CHs' & see if the problem continues or goes away.

Static

I had hoped this product would have mobile implications since I am a mobile DJ and wanted to use this product to drastically cut down set up time. This product may yet be useful in more permanent controlled situations such as Auditoriums or Gyms but if you can't control the conditions it will embarrass you. Bought the product on Friday and tested it in my garage just to get the feel for it. I knew I would have field test to really gage the range so the next day I showed up extra early to my event(a Wedding) with the product in tow. I set it up and enjoyed the quality of the audio while it was working.However, if someone was to walk by the transmitter or just stand for a moment between it and the receiver my speakers would let out loud static or pop sounds. It basically sends a high quality unreliable signal. I was in denial for a bit because I really wanted it to work but as I ran though scenarios in my head of a guest bumping it or just generally dancing by it and it letting out a loud blaring static noise and how badly that would represent me and the company I work for, I reluctantly decided to go with wires instead. I would actually be fine if it cut to silence instead of static much like a wireless microphone does when out of range. But the static just draws attention to the fact that there has been signal loss and is impossible to hide.

    Returning for a unit that falls within the new legal frequency ranges due to the FCC changes I live in Florida so the 600++range is definitely a no go, other areas of the country will be no go over the next couple years
