EV-20R
Sound Repeater
EV-20R
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.
- Dedicated file management software is supplied with the product.
- Audio file library is available on the supplied CD-ROM.
- Customized WAV files can be uploaded.
- Direct recordings can be done by front panel operation.
- Instant playback by front switch operation.
- Dry contact inputs are available to play and stop audio files by external devices such as sensors, program timers or manual switches
- Repeat audio files as set by the built-in interval TIMER.
- Up to 4 different messages can be stored in a built-in flash memory and played back.
- The maximum total recording time for the 4 messages is 6 minutes.
- Recorded data is not compressed, ensuring high quality sound output.
- Automatic Gain Control (AGC) can make recording audio levels uniform.
- An incorporated 3 W/ 8 Ω power amplifier allows direct connection with a low-impedance speaker.
- A USB interface permits audio data to be transferred from a PC with software.
- Live broadcasts can be made without recording by using a microphone or an audio player.
