Alto Stealth 1 Mono UHF XLR Wireless Audio System

AA battery or USB power gives you flexible operating options for presentations, performances and PA setups where a cable run is inconvenient.
Alto Stealth 1 Mono UHF XLR Wireless Audio System
The Alto Stealth 1 provides a wireless alternative to an XLR audio cable. Its compact transmitter and receiver carry one mono audio signal between compatible equipment.
Wireless Connections for Your Equipment
Use it with suitable mixers, powered speakers and dynamic microphones. Support for microphone and line-level signals makes it useful for several live sound applications.
Battery or USB Power
Choose AA battery operation for a portable setup or USB power when a suitable supply is available. Alto specifies four-plus hours of battery operation.
UHF Audio Transmission
The system uses UHF radio transmission, with a published 100-plus-foot line-of-sight range. Plan placement around the actual room and sound-check before use.
Keep Your Setup Practical
Choose the connection you want to replace before ordering. Check access around the XLR sockets and retain a wired option for occasions when venue conditions make it preferable.
Who Is the Alto Stealth 1 For?
- Mobile DJs: consider it for a mono audio connection where running a cable is inconvenient.
- Presenters: assess it when planning microphone and PA connections.
- Live performers: consider a compact wireless link for compatible equipment.
- Sound technicians: keep it available for temporary audio routing.
Plan around the number of audio signals you need to transmit. A mono link and a stereo connection require different setups.
