What are the capabilities of modern test equipment and its ability to test very low noise and distortion devices? Can test equipment of today keep up with increasingly impressive specs? Are the specs real? We’ll review some real world examples from both the electrical audio test world as well as room acoustics testing.
Join Chapter 36 Wednesday, February 15, at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Audio Precision buys lunch. Members and visitors are welcome as always.

An attentive crowd at the KFMB studios heard Sumnit Singh make a case for using the technology developed for consumer mobile devices to relay news audio and video to broadcast outlets over private networks. It should be interesting to see if stations step up to the plate to capitalize this evolution, or if an organization will step up to finance the movement and then resell to broadcasters, or if the technology will die on the vine before being rolled out.
The SBE gang held its annual holiday luncheon this year at Mimi’s Cafe in Mission Valley and had a great time of it. Congratulations to those who walked out with prizes. Nigel Worrall received a ham radio handi-talkie from RF Specialties. Bob Gonsett, Steve Frick, and Barbara Lange walked off with chocolates or wine from Piper Digital and Utah Scientific. Everyone got great food and conversation.
When broadcasters swap CD’s, cart machines, turntables and audio consoles for PC-based digital playout, mixing & processing systems, we call that Virtual Radio. At our next meeting, guest speaker Bill Bennett, Lawo’s Radio Applications lead in the U.S., will describe virtualization in greater detail by outlining the real applications in use today. He’ll explore how broadcasters may now reap operational benefits and gains by capitalizing on I.T.’s investment in R&D and will discuss virtualization’s anticipated role in content creation and broadcast workflow in the future.
Virtual Radio is a hot topic. A recent episode of This Week in Radio Tech (TWiRT) featured a Lawo presentation on this topic. How did they conduct their broadcast interview? Virtually, of course!
Lawo is a provider of virtual radio products, digital mixing consoles, routing systems, video solutions and turnkey systems for the professional broadcast industry. Their equipment is utilized by TV and radio stations, production companies, and theaters worldwide.
Bill Bennett made his presentation Wednesday, November 9th, 2016 at iHeartMedia, San Diego before a sizable audience of local broadcast engineers.
About the Presenter
Bill Bennett has been a long time audio engineer and project manager, leading media venue technical set-up teams for several Olympics. He’s also managed NBA, NHL, and regional events. He joined Lawo last year.
Many, if not most, radio stations these days have an Xpress box to bring them some flavor of satellite-delivered content, whether a talk show or syndicated music broadcast. But did you know these receivers are made in San Diego? Did you know they can be programmed to operate as self-contained radio automation systems? What can networks do with these store-and-forward devices?
Damon will talk about their watermarking and monitoring technology as well.
Pico Digital started as Pico Macom in 1969, selling TV modulators and related RF devices for the cable TV and hospitality markets. They still make and sell sophisticated cable RF modulators, but have widened their offerings to include radio and TV IRDs.
Damon Semprebon of Pico Digital will give a talk on the capabilities of the Xpress line of receivers and other Pico products of interest to TV and radio broadcasts Wednesday, August 10th at 12 noon at KFMB, 7677 Engineer Road in San Diego. We’ll have a small lunch provided by Pico Digital, then the presentation. Members and guests welcome.
About Our Presenter
Damon Semprebon has 30 years experience in technical project management, product development, and other technical services. Before coming to Pico Digital a year ago, he spent 25 years at the San Diego company variously known as Comstream, Tiernan, Radyne, Comtech, and International Datacasting.
With the FCC auctioning UHF-TV broadcast spectrum to telecom, “white space” is destined to be a mostly obsolete concept.
Will there be replacement spectrum for our wireless microphones?
How soon will we have to change channels again?
Will broadcasters and other users be reimbursed?
Can we use Part 74 spectrum for wireless mics and IFB?
Kelly Fair of Lectrosonics will discuss wireless microphone and IFB spectrum at a Chapter 36 SBE meeting 12 noon on June 15, 2016 at KFMB Stations, 7677 Engineer Road, San Diego. Kelly will provide a lunch in the station deli, then move on to Studio A for the presentation. SBE members and guests are welcome.
About Kelly Fair
Kelly has been in technical broadcast audio sales for 27 years, representing Sennheiser, Riedel, Wohler, and most lately, Lectrosonics. Kelly lives, and occasionally beats a set of drums, in Los Angeles.
By now, you’ve likely heard about the audio-over-IP protocol called Dante. It’s low-latency so that you can use it with live audio, and can pass through most data switches. Many of the largest broadcast suppliers have adopted it. RTS, the intercom company that has been around since the 1970s, will come to town and explain why their latest generation of products is knee-deep into Dante.
They can answer a few questions you might have:
What data rates are used?
What is the packet structure?
Does it play well in my network?
How many audio channels can fit at a time?
What is its latency? Will my air staff hear an echo?
When should I favor analog audio, if at all?
Are there phone apps that work with intercom systems now?
Jeff Shorsher of RTS/Telex will sort out these topics and more in a meeting Wednesday, May 18 at 12 noon at KFMB Stations, 7677 Engineer Road in Kearny Mesa. Join us for a lunch provided by RTS, then a general meeting and presentation. Members and guests are all welcome.

Some of what’s going on in TV broadcasting would have been impossible just a few years ago. For example, stations are now converting their news or event ticker text to speech on a secondary audio channel for the visually impaired, bringing them information never before heard. We can now normalize audio levels within an MPEG transport stream.
Cobalt started as a video accessories company in the analog broadcast era, but has taken on serial digital and now transport stream processing. Come see what solutions they have to offer. Cobalt Digital visits Chapter 36 Wednesday, March 16 at 12 o’clock noon at KGTV, 4600 Air Way, San Diego to discuss these technologies and more. Cobalt will provide lunch.

Lukas Hurwitz, West Coast Sales Engineer for Wheatstone, will present on Advancements in AoIP Networking.
The presentation will cover the latest developments in audio networking with WheatNet-IP. Additionally, Lukas will go over the major benefits for Radio and TV broadcasters and provide examples of the integrated software and hardware tools currently available.
Outfitting a TV channel with playout automation can be a real challenge. “Channel-in-a-box” solutions turn out to be more expensive than advertised because you end up buying a dizzying array of modules and licenses to get EAS, graphics layers, dynamic content, satellite network sources, and ASI inputs and outputs. Your vendor can make your product ownership experience frustrating because support is overseas or you have to pay for a big contract.
Local supplier DVEO is gaining traction with some interesting solutions for broadcasters of all kinds, whether a cable station, LPTV station, government channel, or a subchannel at your major affiliate TV station. DVEO will appear this month to show us modern tools for inserting commercials, network and local media, graphics layers, and even EAS into an SDI or ASI stream.
We’ll also get a look at a 4K resolution brand spanking new H.265 HEVC encoder and decoder pair. While you may not think of 4K as a practical format for broadcast yet, you can still use this codec for transmission of conventional HD video at about half the bandwidth of H.264.
Join us Wednesday, January 20 at 12 noon at KFMB, 7677 Engineer Road in Kearny Mesa, San Diego. DVEO will buy us lunch.
Once again Chapter 36 will meet to simply talk shop, share some cheer, and toast to a great coming year.
Our past meeting place, Cozymel’s at UTC, is now rubble, so we’ll gather at Casa Machado, 3750 John J. Montgomery Drive, on the south side of the runways at Montgomery Field in Kearny Mesa, San Diego. Date is Wednesday, December 16, 2015. The meeting time is a bit earlier, at 11:30AM.
Please reserve a spot if you intend to join us so that we can plan sufficient table space. Whether you’re a member, a guest, or just came to town, you’re welcome. Expect to spend about $15 – 20 for lunch and a tip.
If you would like to donate a gift for an exchange, let us know and bring it with you.
