DNF Controls installs a Tally Manager system for Maryland Public Television

DNF Controls announced the installation of a large-scale Tally Manager system, part of a major facility upgrade at Maryland Public Television, orchestrated by system integrator Digital Video Group.


“We upgraded their main production control room with a 4 M/E Grass Valley Karerra switcher and Kaleido multiviewer system, plus a Utah Scientific 528×528 hybrid router,” said Joe Davenport, Digital Video Group’s vice president of engineering.


Maryland Public Television generates hours of live and recorded local content each week, plus programming for PBS, so the entire project – from installation and testing to commissioning and training – was on a tight, two-week schedule, with DNF’s Tally Manager system a key interface between the Grass and Utah elements. Adding to the challenge, the room transitioned from CRTs with under-monitor displays to multi-viewers, so the new tally control had to display multiple levels of four ME switcher status and exceed their old system’s functionality.


“DNF was our ‘go to’ solution – we’ve done other large projects with DNF and were confident in their technology and people,” Davenport noted. “Their on-site engineer did a bang-up job … our guys were busy getting the switcher and other gear up and running … I told him what needed to be done and stood back. It was done right, on-time, and to everyone’s satisfaction” he concluded.


“We’re gratified to play a part in the success of this high-profile project and greatly appreciate the confidence Digital Video Group placed in us,” said Dan Fogel, chief technical officer of DNF Controls. “Despite a very tight timeframe, their team’s proficiency and professionalism made our part of the installation that much easier,” Fogel added.
