Working With Audio Signals

---

For most of the past century, working with audio signals was a very straightforward process. The audio information was converted to electrical signals in the form of a varying voltage between the two conductors in a pair (balanced) or between a conductor and the ground reference (unbalanced).

Its a MADI World

---

At this year’s NAB Show in Las Vegas, 3D solutions were still a hot topic — but one emerging technology threatened to steal the show. In fact, the rapid growth of devices that support the Multichannel Audio Digital Interface (MADI) has more potential for simplifying broadcasting operations than perhaps anything else.

Lighting up Yorkshire

---

The Yorkshire town of Rawmarsh looks like an easy target. Its trolley buses have come and gone and its two train stations were both wrapped up more than 40 years ago.

Getting the basics right

---

In this column in the last issue of TV-Bay I wrote that, thanks to technology, some jobs in broadcast are now more suited to people who have no broadcast training. It was, in the way of columns at the backs of magazines, more a call for comment than a reasoned argument. As it happened, the same issue also included an article by the admirable Freddi...
