Digital Announcer
Optimize your PA system with versatile control
Adding the TOA EV-700 Digital Announcer to your existing PA system provides numerous benefits for
large facilities ranging from retail stores and shopping malls to schools, factories and railway lines. The
EV-700 permits easy manual distribution or automatic activation by external device of timed and repeat
announcements, BGM and other audio programs with excellent sound quality. Creation and editing of
various sound source files and programs, updating of settings and activation of announcements can be
handled easily by direct input or managed remotely via a network. And prerecorded emergency messages are ready for broadcast the moment they are needed.

and other content are recorded on a memory card, eliminating concerns about deterioration in sound quality with repeated playback.
Users can create or edit/update sound source files by directly inputting new phrases or combining prerecorded phrases
to create audio programs that meet their particular PA needs.
