The TOA EV-20R digital message repeater with USB is a convenient addition to sites where the same message or music is repeatedly broadcast. Up to 4 types of music and messages (6 minutes total time) can be recorded and played back. The USB port facilitates recording by transferring the supplied sound sources from a PC to the unit. The unit's small built-in amplifier enables small-scale broadcasts through a simple speaker connection.
The EV-20R Sound Repeater is used to record and play back sounds produced from a microphone, CD player or other sources. Its particularly ideal applications include repeated broadcasts of the same message in schools, department stores and factories. Flash memory is used as a recording medium, and up to 4 different messages can be recorded and played back. The Sound Repeater also permits broadcasts to be made directly from the microphone or CD player without recording.
