The WM-D5300 Digital wireless transmitter has been manufactured for use with a UHF system. It is for use in speech reinforcement applications.

This wireless transmitter employs a digital transmission system that is effectively immune to interference. Further, not only does TOA's unique information concealment technology (Encryption Setting function) ensure high confidentiality and security against eavesdropping, but their code setting and transmission output selection functions ensure that this transmitter is also compatible with a wide range of operating conditions, such as use of the same transmission channel between adjacent areas.
