"Though the standard analog party-line beltpack-and-headset intercom is alive and well in thousands of venues worldwide, technology has continued to advance with the availability of faster processors, robust VOIP algorithms, DSP, networking, and other computer and telecommunications techniques.

Going beyond the large digital matrix intercom card frames and stations used almost exclusively in television broadcast applications just a few years ago, multi-channel digital matrix intercoms in 1 RU and 2 RU chassis are now readily available and can be found at the core of some live show and touring communications networks.

The transition to digital is now underway in wireless intercoms - allowing more flexible point-to-point as well as party-line communications on more than one channel without being tied to a cable. Digital wired party-line systems are now offered, with two or more channels per user and the ability for each user to choose and switch among various party-line or point-to-point conversations at the beltpack.

Virtual intercoms have also become a reality, where a laptop or desktop computer can become a fully functional multi-channel intercom station, with party-lines, point-to-point links, and program monitoring at the click of a mouse - plus the ability via IP connectivity to bring remote individuals and teams into the same production communications in real time.

All of these devices can be interfaced together, so a matrix or virtual intercom core can seamlessly add digital party-line and wireless for a flexible communications network that meet the needs of director through stage tech. Let’s have a look at available intercom technologies," says Gary Parks in the ProSoundWeb article, Current Options In Production Communication Systems.

Friday Fun: Happy Birthday Mr. Hertz!

Did you notice this neat Google Doodle this past Wednesday?

Well, it was in honor of the 155th birthday of German physicist Heinrich Rudolf Hertz. You know, that guy that proved that electromagnetic waves exist, otherwise known as Hertz. A very pivotal discovery for us living in audio-land.

The Huffington Post wrote a brief article about Hertz and Google's homage to the man. Here's some excerpts:

"Heinrich Rudolf Hertz, born in Hamburg on February 22, 1857, was the first person to prove electromagnetic waves exist...and that electricity can be carried through them."

"While this Google doodle is pretty simple, it's not without its hidden features.....The wavelength's repeating pattern outlines the shape of Google's usual logo."

"Great as has been the influence of his work in the short period which has elapsed since its promulgation, the importance of its ultimate results can scarcely be overestimated. [from the physicist's obituary]"
