The Alto Professional Stealth Wireless Pro is a state-of-the-art wireless solution that eliminates the need for speaker cabling and offers even greater performance capabilities than the already outstanding original Stealth Wireless system. With Stealth Wireless Pro, it’s easy to add wireless audio connectivity to any active loudspeaker, obviating the necessity for long, complex cable runs, simplifying setup and teardown, saving time—all without any compromise in audio quality. The system works perfectly well through walls, floors and ceilings, providing setup flexibility that far exceeds conventional hardwired systems.
Stealth Wireless Pro contains a single dual-channel transmitter with a 2-antenna system (either dual mono or stereo switchable) for true diversity operation. A front panel LCD screen with dual frequency display conveniently shows the RF frequency and channel as well as the AF signal level for each channel. The trim-sized unit is easily 1U rack-mountable, with two units fitting side-by-side in a 19-inch rack. The Stealth Wireless Series adds wireless connectivity to nearly any active loudspeaker system. In addition, the Stealth Wireless Series greatly reduces the setup time of a traveling or temporary sound system by eliminating the need for lengthy and unsightly cable runs that may otherwise interfere with the dance floor, patrons, or venue staff.
Stealth Wireless Pro can be set for mono or stereo use. Two XLR + balanced TRS 1/4-inch combo inputs on the transmitter accommodate the main outputs from nearly any mixing board or console. Each of the receiving units has a single XLR output to send the signal to a powered speaker array or a traditional amplifier-and-speaker combo. Two receivers are included with the system. They feature slim-line metal housings, dual removable and swiveling hinged antennae, delay line functionality and a Feature Lock Switch to prevent unintended operation once the system is configured.
For sound professionals, setup time and simplicity are of paramount importance. But any reduction in audio quality for the sake of convenience is totally unacceptable. Stealth Wireless Pro delivers exactly what professionals demand—faster setup/ teardown, LCD displays for instant visual confirmation of system configuration, and uncompromised audio quality.

What is an extended warranty?
An extended warranty is an extension of your original manufacturer’s warranty. Most manufacturer’s warranty their products to be free from defects for up to one year from the date of purchase. This warranty virtually guarantees you that if your purchased product fails, CPS will protect you from the high costs of replacement parts and labor necessary to repair your product. Most Consumer Priority Service extended service plans lengthen your product’s coverage for up to an additional 48 months (4 years) to ensure you get years of performance satisfaction from your newly purchased product.
How is this different than the manufacturer's warranty?
A manufacturer's warranty usually offers limited coverage for a limited time, with parts and labor carrying separate lengths of coverage. For example, a common manufacturer warranty of a television might cover a consumer for one full year on parts defects but only 90 days on the high cost of labor involved to change those parts. CPS extended service plans provide comprehensive, long term, even length coverage. This means that should your product fail within your plans coverage time frame, both parts and labor costs are covered.
When does Accidental Damage Coverage begin?
Accidental Damage protection begins 30 days after purchase.
Who will perform the service on my product?
PS works with tens of thousands of authorized service professionals. Each technician is extensively trained by the respective manufacturers to provide service on your products. Authorized technicians must complete annual and bi-annual continued education exams in addition to being well learned in manufacturer supplied update bulletins to ensure their level of expertise is as current as the new products which come to market.
Can I transfer my CPS plan to another person?
Yes, all plans are transferable. Please call (800) 905-0443 for further assistance in transferring your plan. Please note: A transfer fee of $25.00 will apply to all warranty transfers.
Will I have to pay a deductible or any other hidden costs?
Every CPS service plan carries a zero deductible along with low premiums. This means that with a CPS service plan there are no high upfront costs and we are committed to cover 100% parts and labor costs on any authorized claim. Generally, the amount of a deductible is almost always proportional to the amount of the premium charged. In order to have a lower deductible, even as low as $0, the plan holder would generally have to agree to a higher premium. For those who want lower premiums, they must agree to a higher deductible.
How do I file a claim?
Logon to CPS Central where you can initiate a claim on your product. You may also call the toll-free number (800) 905-0443 and have a qualified representative file a claim for you with the information you provide.
