By using MC/TDMA/TDD radio transmissions both to and from your microphone, the system is able to co-exist with wireless 802.11 networks and GSM cellphones without interference. It also includes digital encryption technology for secure communications. The transmitter has analog 3.5mm input and output connectors, which can be switched between mic and line level operation, and also has the ability for both inputs and outputs to be mixed to a single channel.
Because the system is full-duplex, the input connections provide the ability to hear program audio using a 2.5mm earpiece attached to the HD wearable microphone (available separately). Depending on the application, it is possible to feed a single audio feed back to each earpiece ”allowing for translation, personal hearing assistance, or other services to be incorporated into an application.
