A seismic shift is one that literally means moving the Earth. That's a big change. When I got started in 1974 there were no computers, cell phones, digital circuitry. It was all analog. We learned the art of analog design because that was the only way to build a high-end audio product. Analog in, analog out. Front panels were controlled by knobs and switches rather than what we take for granted today, the remote control—itself enjoying a rich history including the Blab-off in 1952 to quiet TV commercials, the Space Commander channel tuner in 1956 using an ultrasonic "clicker", and Apple founder Steve Wozniac's CL 9 wireless universal remote in 1987. Contrast those early days of analog with today's amalgam of digital and analog and we can see the Earth has indeed moved. Few products today aren't hybrids of digital and analog, if even just to control the front panel LED. Over the next few days, we'll take a look at some of these major shifts.
