The Mercury USB Adapter is a small scale alternaive to the MIU that instantly converts a PC to a Mercury IP communications station for one or two users. Virtual or hardware panels allow users to speak and listen to up to 8 independent IP audio channels at once. This includes communications with panels, radios, telephones and other third-party communications equipment located anywhere on the Mercury network.

To minimise impact on the host PC, all audio processing is handled by the USB adaptor. Dedicated jacks and connectors are provided for peripherals like headsets, speakers and microphones, and push-to-talk switches.
