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.

1 Programmable Channels: The ability of a headphone/receiver to lock down exactly how many channels a person can choose. This stops dead air channels.
2 Secure Channels: Utilize one or more frequenies/channels that others with the same headphone are unable to tune into.
3 Power saver: After 15 minutues if there is no audio, the headphones turn off. This allows for end of show, to save time manually turnning off the headphones.
4 While the audio will penetrate walls,celings, and other objects, this will have an impact on the maximum distance.
5 Power levels will determine how far a signal will travel. For smaller spaces lower power is recommended to reduce the risk of audio quality if there are more than one transmitters in use.
6 Don't be fooled by marketing by other brands who purchase from us that say "Noise Canceling." Anything that covers the ear can be considered "noise canceling". We want to be transparent with our customers. These headphones are not "Active Noise canceling," which is a technology that uses microphones to detect and cancel out external sounds so that you can listen to your audio without interruption.
7 Hi-Fi Audio is a special audio that is reproduced as accurately as possible to the original recording.
8 Radio Frequency Filter is a technology that removes the natural "hiss" noise that Radio Frequencies create, making for a crystal clear sound.
