        DM Engineering has been designing and building custom equipment for the broadcast industry since 1992. Being personally involved in the broadcast engineering field, most of their products have been created out of need.

        From the variety of products designed to simplify the interfacing between both operators and automation systems for the Sage Endec Emergency Alert System encoder-decoder, studio products like their Mic Pro, Slave Relay Pack, Solid State Relay Pack, single and multi-line Phone Flashers, and their Don't Forget and Opto-Probe Status and Alert indicator systems, to signaling devices like their Silence Sense and Event Paging product lines, DM Engineering has devoted its focus to the devices the average engineer wants and needs, while keeping the prices for these products low.

        Markertek is an authorized dealer for the entire DM Engineering line. If you don't see what you're looking for, contact us and we'll do our best to get it for you.
