IMIC-5 Single-Channel UHF Wireless Receiver
Model IMIC-5
Overview
The IMIC-5 is a single-channel UHF wireless receiver with antenna diversity, developed specifically for educational and presentation applications.
Its 8-band architecture with 50 channels per band and a total bandwidth of up to 128 MHz allows operation in congested environments with ample frequency flexibility.
The expansion functions via RS-485, USB, and automatic synchronization with the EC-50 facilitate management of multiple classrooms and systems from a central point.
