Product Overview
For department stores, offices, schools, stations, and anywhere announcements are needed, the EV-20R helps assemble a system that makes good use of the advantages only digital technology can provide. Using flash memory for recording and storing messages allows unlimited announcement repeats without the sound deterioration associated with analog recording and repeated playback.
The EV-20R 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.
