New version 4.  Ogg Vorbis, FLAC, and WAV playback (and MP3).  To-the-second scheduling,  300%  faster file upload speeds, user-editable GUI, two password levels (admin and control-only), lots more.  Now – playlist creation and scheduling right from the web interface.

The Schedulon digital message repeater offers both instant playback of your  audio via a convenient knob and screen, and also allows you to schedule sounds for automatic unattended playback – i.e. A bell every day at 08:00, safety announcements every 30 minutes, a special song every Saturday at 10:00, etc. Robust flash-RAM memory (no hard-drive) makes the Schedulon message repeater tough and reliable – and unlike a PC-based solution, it can’t catch a virus or crash due to operating system errors.  A robust internal Real Time Clock (RTC) ensures accurate time (+/-1 sec/mo), or the unit can be synched to an internet Time Server. The Schedulon stores 200 hours of audio with the included drive, and with larger SD cards it stores over 10 HOURS of audio.New Playlist feature! Now you can create playlists of audio files which then be both scheduled for playback just like a single audio file as well as assigned to a knob for on-demand playback. Playlists can be set to either play the audio file set in random or specific order. » Read More

The Schedulon can record audio from its stereo line-in jacks – audio is encoded as either OGG Hifi profile 44kHz format or 24kHz ADPCM-WAV format. Recorded audio files can be assigned to any desired knob location for playback.  You can also use the recorded sound in a schedule for automatic playback.

The Schedulon integrates with your existing audio systems (i.e. internal building audio systems) using standard line-level cables, or order it with any Technomad Turnkey PA System. [ Technomad makes complete Carillon systems also – click here for more information. ]

Applications: facility scheduling (schools, airports, hospitals, casinos), corporate audio (no CDs to misplace, looping BGM and on-demand Cues), training, sports facilities (load team music or special effects for instant playback), automatic safety announcements (i.e. ‘airport announcements’), theme park audio, sound-effects, pool-side music or DJ applications, and much more.  » Read an application article about the Schedulon at Simi Valley Hosipital.

Load sounds by simply plugging the Schedulon’s SD Card into your computer for fast file transfer – or upload / manage files via Internet /  LAN connection.  Or – fieldrecord audio via the Schedulon’s built-in recording function, then schedule the audio for playback or assign to the knob for instant access.

Unlike competing devices, ALL data storage – sounds, knob assignments, settings, and schedules – are stored on one, removable internal SD card. This means you can ‘clone’ an entire Schedulon setup to a folder on your computer, and even duplicate that folder to new SD cards to create exact working duplicates of a configured Schedulon

You can remotely manage the Schedulon via Internet / LAN connection – upload or delete audio files, edit the schedule, trigger sound playback or recording, make knob assignments and more – using any standard web browser.   Web interface is password protected.
