RF-ResQ rack

Kaltman Creations RF-ResQ

Founded by Mark Kaltman in 2006, Kaltman Creations was never about doing things the usual way or creating “me-too” knockoffs. But perhaps that’s the way of many innovators who shape the direction of an industry. Now his latest product, RF-ResQ™ continues Kaltman’s tradition of coming up with something that redefines the way many of us will work in the future, just as he did with earlier inventions, like the Invisible Waves RF Command Center, the RF-id SOLO and Station, RF-intermodPro and RF-Vue.

The Mixing Algorithm

The recent crash of a German airliner — a disaster brought about, apparently, by the willful act of one of its pilots — triggered a predictable discussion about the role that automation might play in avoiding such catastrophes in the future.

Once upon a time on these very pages, we discussed the procedure and benefits of using Real Time Analysis (RTA) as a tool for revealing problems in a live sound system. RTA or spectrum analysis can help expose room anomalies, problems with a P.A. or to help ring out monitor mixes (“Interpreting RTA Measurement Techniques,” March 2013, and “Ten Tips for Better Monitor Mixes,” Jan. 2014).

The trucks are loaded. the buses are rolling and the tours are well underway with audio rigs small and large flying off the shelves and onto trusses everywhere.
