There has been a lot of talk about convergence in the cabling world; some of this has been driven by new technology and market overlapping. Today’s integrator has the ability to install a system that covers phones, computers, security, audio/video and even low-voltage power.

I was talking yesterday to the outgoing CEO of a large stock fund. He wanted to know how Belden fit in to the rapid change of technology. I gave him my usual schpeal about how we're looking to the future, how networking with revolutionize the way TV stations are built and operated, how this will empower the "little guy" so we will see tens of thousands, even millions, of streaming video stations on the internet, with the same quality as what we're already used to.

Even my friends at Miranda offer a TV station-in-a-box. And couple this with the rise of 4K video and 8K coming after that, and we have a landscape as alien as any world outside our own. I also mentioned that the only thing that really mattered was "compelling content". You've got that and you have everything!

On Monday, April 28, 1969, I walked into the Hilton Hotel in downtown Los Angeles on Figueroa Street. The hotel is still there, but now part of another chain. I was a very excited 18-year old. I could barely contain myself because I was about to enter my very first convention of the Audio Engineering Society. Was this my first convention ever?

No, I had been attending tradeshows and conventions for a few years. The key one was Wescon, they were way ahead of their time and gave each attendee a "credit card" embossed with your name and address. I took it to every booth I could and, at age 14, the mail started pouring in. My parents were mystified. I actually filled up a three drawer file cabinet with all that literature, arranged in alphabetical order. (Some of you have suspected, now confirmed, that I was seriously OCD back then. I haven't improved much.)

I'm a huge fan of a British TV series from the 1960's called "The Prisoner". It starred Patrick McGoohan (reprising his 'Secret Agent' role) who is captured and sent to this strange land where they try and break him. It was only 13 episodes long and was seen as a summer replacement series in the USA.

The location footage for that show was filmed at a resort on the northern Welsh coast called "Portmeirion". I have visited there many times. Once I went by train from London to Portmeirion, which was one of the strangest trips I have ever taken. The train stops in the middle of Wales at a train station literally in the middle of nowhere. I was told it is the only train station NOT accessible by car in the entire British Isles. The reason for it is that the Welsh railroad uses a different rail gage, so the British trains cannot go there. You get off one train and on to another, just because the gage changes.

Do you know the difference between a balanced line and an unbalanced line? If we're talking about analog audio, this difference between balanced and unbalanced is also the difference between consumer products, which are almost always unbalanced, and professional, which is almost always balanced. To go into the details of these differences would take a number of blogs, so I'm going to try and condense it here.

If you want to know more details, just invite me out to speak at your local group. Are you a member of the Society of Broadcast Engineers? Perhaps you joined the Society of Motion Picture and Television Engineers or the Audio Engineering Society. All three of these, and many other similar organizations, have local groups and often have lunch or dinner speakers. I would be delighted to fit you in my schedule and come give a presentation on balanced lines or many other subjects.

You hear it everywhere: The world is going digital. But, hold on there, that might be true for video, but it's not true for audio. Just go visit the major networks in New York or LA. The majority of consoles they're running are still analog. Look in any broadcast or pro-audio catalog. Analog audio consoles still outsell digital audio by some huge number. And it's no wonder. The performance of analog cable was never a problem.

The limits in analog are based more on the boxes (preamps, consoles, distribution amplifiers) than on the cable itself. As long as you have reasonably low capacitance in the cable, at around 30 pF/ft. or 100pF/meter, you can go very far without significant loss. The real distance determinator is the source impedance of the device feeding that audio line. If you can get down to 100 ohms source impedance, you can go over 1,000 ft. (300m) before you're even 1 dB down at 20 kHz on that 30pF/ft. cable.

We're very proud of our professional audio and video cables. Our professional cables are so superior that most broadcasters simply won't use anything else. But when it comes to commercial designers and installers, sometimes they don't need all the bells and whistles we put in and they're willing to take less quality (for a lower price, of course).

Where we test every foot of cable we make such as our precision broadcast coaxes, most manufacturers "batch test" meaning they test one reel out of a batch of 25. By the way, when we say we test every foot this means we have test gear in the factory where the cable is made. Want a tour of a Belden factory? We would be happy to arrange a tour. No kidding, just send me an email.
