In the continuing saga to explain our measurements charts, senior technical editor Mike Wood explores ground control for your home theater: the preamp/processor.
Launching the space shuttle requires the actions of thousands of control systems and hundreds of people all directed by, ultimately, one person. Technicians sit in front of dozens of monitors, checking systems, subsystems, weather patterns, and so on—all to make sure that, when the chief gives the order, the big hunk of steel sitting on the launch pad is able to take off without a glitch. You may not be igniting hundreds of thousands of pounds of rocket fuel when you press play on your DVD-player remote, but you are trying to launch your home theater system, and you usually want it to happen without too many hang-ups. The main component that controls this process is the pre/pro, or preamp/ processor. This is the subject of our latest Boot Camp in the series explaining the technical measurements that accompany our product reviews.
