- Page 1 DM-8 DIGITAL MESSAGING UNIT Item ref: 953.053UK User Manual Version 3.1 Caution: Please read this manual carefully before operating Damage caused by misuse is not covered by the warranty...
- Page 2 Introduction Thank you for choosing an Adastra DM-8 digital messaging unit for scheduled music, announcements, and alerts in your public address system. This unit is designed to provide flexible and hassle-free automation of audio playback, fully programmable by the operator.
- Page 3 Preparing the SD Card The DM-8 message player requires an SD card (or microSD with adaptor) to read the message and schedule information from. The SD card should be formatted to FAT32 and is recommended to be between 4GB and 32GB in capacity.
- Page 4 Save the software file to either the SD card or onto the PC and double click this .exe file to run from the stored location. Any schedules that are created and exported will be saved to the same directory. The opening window of the DM8_Schedule_Editor.exe application is a new blank schedule, which can be edited, exported, imported (from a previously made file) and saved as a backup or copy.
- Page 5 This file must be saved to the root folder of the SD card. The file name must be schedule.txt for the DM-8 to recognize it. The DM-8 looks for the schedule.txt file on power-up and reads it to set up the message playback schedule.
- Page 6 MIC level and if it is a condenser type which requires phantom power, set PHANTOM to “on”. For a line level signal (such as a CD or mp3 player or even another DM-8), select LINE level and PHANTOM to “off”.
- Page 7 If the switch is held closed (as with a latching switch), the track will play repeatedly, retriggering until the switch is open. If connecting the DM-8 to a fire or security alarm panel with a trigger voltage output, use a relay switch that operates at the appropriate trigger voltage to close the required contacts when the alarm is activated.
- Page 8 Viewing the Schedules The DM-8 can be automated to play back of any of the 99 tracks in the MESSA folder at a pre-set time on selected days of the week. There are no special limitations on the message mp3 content, so this could be an announcement, sound effect or even a full music mix.
