Alto Professional has announced the Stealth Wireless Pro at NAMM 2015; an innovative system that eliminates the need for speaker cables, adding wireless audio connectivity to any active loudspeaker without any compromise in audio quality. The system works through walls, floors and ceilings, providing setup flexibility that far exceeds conventional hard-wired 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” rack. The included rack kit includes BNC connectors for attaching antennae at the front of the rack. BNC extension cables are also included. This self-contained kit provides a convenient wireless path to carry a stereo audio signal from the main mixing/listening location to the sound system. 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 travelling 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″ 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 swivelling hinged antennas, delay line functionality and a Feature Lock Switch to prevent unintended operation once the system is configured. The Stealth Wireless Pro Expander Pack provides two additional receivers for adding more loudspeakers to a system and providing increased coverage. The user may add as many expander packs as needed to accommodate any size system.
