    The demand for wireless microphones has grown as a result of the increasing prevalence of videoconferencing and web conferencing. Audio-Technica’s Engineered Sound Wireless Systems is a DECT wireless system that offers simple, smart, and scalable high-quality audio. This system overcomes many challenges of conventional wireless microphones, such as frequency coordination and the limited number of simultaneous microphones.

    Operation is incredibly easy for end users, with microphones ready to use by simply removing them from the charging station. At full charge, the batteries offer all-day operation. Installation is also made easy using PoE to power the receiver and Dante audio output capabilities. Wiring is as simple as connecting a single Cat 5e cable to a PoE switch. This helps streamline the installation process, with no need to worry about having to install multiple antennas. System integrators are able to configure detailed settings to meet a wide variety of end-user needs.

    Seamless setup and management are controlled via Audio-Technica’s Wireless Manager software, which is capable of managing multiple wireless systems, including UHF wireless systems, from a single screen. In addition, AES256 encryption support comes standard, providing superior security and reliable operation.
