The TOA EV-20RPS is a compact digital message repeater designed for facilities that require scheduled or triggered audio playback without operator intervention. Retail environments, transit facilities, corporate lobbies, and light commercial installations benefit from its ability to store up to four distinct messages or chime sequences in onboard flash memory, with a combined recording time of six minutes. The unit ships with the AD-246 AC adapter included, making it ready to install without sourcing additional power accessories. Audio engineers and AV integrators will appreciate the flexibility of the input and output architecture. The front-panel microphone and line inputs allow live broadcasts to pass through without pre-recording, while the terminal block connections for control input and output enable integration with building management systems, door contacts, or scheduling controllers using dry-contact triggers. USB data transfer and dedicated file management software give integrators a straightforward path to loading custom WAV files from a PC, replacing the default chime library with facility-specific content. Compared to consumer-grade players or repurposed media devices, the EV-20RPS is built around the operational needs of installed audio. Uncompressed 16-bit PCM playback preserves audio fidelity through the signal chain, and selectable playback interval times ranging from immediate repeat to one-hour cycles allow precise scheduling without an external controller. The removable terminal blocks, ABS resin enclosure, and optional rack mounting brackets support permanent installation in standard equipment rooms.
