Initially working alongside Graham Buchanan, the current MD, Elliott will take on the job full-time on 1 September 2008 when Buchanan becomes chairman.
Elliott's 30-year broadcast industry career includes stints at Redifon, Sennheiser, Kingston TLI, Encoda Systems and Leitch Europe.
He also co-founded broadcast radio systems installation company Elliott Brothers.
"With the increasing focus on IT-based broadcast engineering, this is an ideal time to be progressing from hardware manufacturing into dedicated television systems integration," said Elliott. "My objective will be to extend ATG's presence into a wider market arena.”
ATG Broadcast Ltd is part of the Danmon Systems Group, a division of DanTechnologies.
The company combines experience of traditional broadcast equipment with computer-based media management systems.
