Spécifications

ChronoPlayer mkII is a reliable and easy-toinstall audio player that delivers messages, sounds alerts and plays music at a scheduled time.

Scheduled audio playback

ChronoPlayer mkII manages a precise playback of WAV and MP3 files all day long and according to a timetable that can last for years. Its internal clock will automatically adjust to time zones and daylight savings time. These functions ensure maximal autonomy to the player.

On-demand playback triggering

Thanks to the 8 input contacts, the delivery of messages, alarms and announcements is possible at any time. The RS-232 serial link will allow communicating with your own devices and increase delivery and control scenario possibilities.

Reliable and easy-to-install

ChronoPlayer mkII is designed for 24/7 operation. Engineered and manufactured in France, it comes with a 3-year warranty. Integration time is reduced: the ChronoPlayer mkII is rack mountable and wired with pluggable terminal blocks.

 

Suggestions of uses:

  • School bell management system: customisable message delivery, safety messages, background music.
  • In factories: break announcements, information along production lines.
  • Retail: informative and persuasive advertising, vendor call.
