Versatile Control and Reliability
Reliable UHF Performance The Stealth 1 operates in the reliable UHF band (863 – 865 MHz in the UK/EU), providing much better penetration and lower interference than 2.4GHz digital systems. The 16 selectable channels ensure that you can always find a clean frequency, while the built-in LEDs provide instant feedback on battery life and pairing status.
Flexible Power Management One of the Stealth 1's most unique features is its power flexibility. For short gigs and mobile setups, a single AA battery offers over 4 hours of life. For permanent installations or all-day festivals, simply plug in the included micro-USB cables to any standard 5V USB power source for unlimited, worry-free operation.

Frequently Asked Questions
Can I use this with a condenser microphone? No. The Stealth 1 is designed for dynamic microphones or line-level signals. It does not provide the phantom power required by condenser microphones.
Can I use multiple sets at once? Yes. Since you have 16 selectable channels, you can operate multiple Stealth 1 systems simultaneously by ensuring each pair is set to a unique, non-adjacent channel to avoid crosstalk.
Is it stereo? The Stealth 1 is a mono system. If you need wireless stereo for a pair of speakers, you would typically use two sets (one for the Left channel and one for the Right).
