Ultra 900 Mobile Transmitter: Ultimate Portability for Silent Discos & Spoken Events

Take Your Event Anywhere, Clearly.

Cut the cords and unleash the full potential of your mobile events with the Ultra 900 Mobile Transmitter. Designed as the perfect broadcasting companion for all Ultra series headphones, this powerhouse unit is specifically engineered to maximize the capabilities of the Ultra2 dual-mode headphones.

Whether you are leading a high-energy mobile silent disco, hosting a multifaceted conference, or guiding a noisy tour, the Ultra 900 ensures your message is heard with absolute clarity.

Unmatched Audio Flexibility The Ultra 900 redefines mobile broadcasting standards. While compatible with standard setups, when paired with Ultra 2 mode headphones, it unlocks an impressive 13 channels (Channels 1-10 plus A1-A3). It also offers selectable SD and HD audio compatibility, making it the ideal choice for events involving spoken word where vocal articulation is paramount.

Advanced Professional Controls Don't just broadcast; command your audio environment. The Ultra 900 is packed with features for professional presenters and DJs:

  • Intelligent Mic Handling: The "MIC DecAudio" feature automatically lowers the music volume (or turns it off entirely) whenever you use the microphone—perfect for seamless announcements over beats.
  • Clear Vocals in Noisy Crowds: Integrated ENC (Environmental Noise Cancelling) technology on the microphone input minimizes background chatter, ensuring only your voice broadcasts clearly.
  • Built for the Long Haul Designed for movement: the unit features a secure belt clip and a robust battery lasting up to 24 hours on low power. With a range of up to 1,500 feet using the high-power antenna setting, you can cover massive venues without being tied to a booth.
