Palma Gil St., Poblacion, Davao City, while its national marketing offices are located in Makati.

It has three radio network brands, namely UMBN News & Public Affairs, Wild FM and Retro.

The origins of UMBN can be traced to DXMC, the first radio station in Davao City and the entire Mindanao region.

[3][4][5] The broadcast franchise was later amended on June 22, 1957, under Republic Act 1832, allowing Torres to establish and operate radio stations in the Philippines.

By that time, the station became Hit Radio later becoming Retro 95.5 while on the other hand, the former became a relay of Manila-based DZRJ-FM since early 2010s.
