The Schedulon digital message repeater from Technomad offers both instant playback of audio via a convenient knob and screen, and also allows sounds to be scheduled for automatic unattended playback. New for ISE 2015 is a playlist facility, while Flash memory is said to make the Schedulon message repeater tough and reliable. Technomad notes that, unlike a PC-based solution, Schedulon cannot be infected by a virus or crash due to operating system errors.
