The Ovation™ 1880 is a classroom audio amplifier designed for regions requiring the 1.88–1.90 GHz DECT frequency band, including Europe, Australia/New Zealand, the Middle East, and parts of Asia and Africa.

The amplifier combines a wireless receiver, mixer, and 50-watt amplifier into a single, easy-to-install device. It drives up to four speakers to provide consistent speech intelligibility for every learner. To support modern instruction, it uses Video Conference Sync with EchoGuard™ to prevent audio feedback loops during hybrid learning sessions.

The Ovation 1880 serves as the audio hub of the classroom, featuring four line-level AV media inputs and seamless integration with assistive listening, paging, fire alarms, and security alert systems.

Works with Ovation wireless pendent and handheld mics available separately and in systems.
