Surround Sound

At the heart of the receiver is the surround-sound processor. The most basic surround processors use a Dolby Pro Logic II decoder. Pro Logic II is a "matrix" system that takes an encoded two-channel stereo signal and converts it to a five-channel full bandwidth (range) playback (Left/Center/Right/Left Surround/Right Surround),resulting in a surround experience. Most TV shows are encoded in Dolby Pro Logic II, as are the majority of VHS videos. You can also play DVDs through a Pro Logic II only-receiver because DVD players can synthesize a Pro Logic II signal that mimics a surround soundtrack. The newer Dolby Pro Logic IIx adds the ability of converting stereo or 5.1-channel surround sound for seamless 6.1 or 7.1 playback.

I check all my life support equipment and camera gear before boarding the Zodiac (rubber raft type boat).

Until recently, options for multi-monitor support were limited. You could accept the fact that your computer didn't support it – or replace the computer entirely. Or, assuming your machine had an open expansion slot, you could take on a DIY video-card upgrade, a project fraught with the joys of research, installation, troubleshooting, and without any guarantee of success.

If you're from my generation and have ever explained the concept of the vinyl record to anyone under the age of 18, then you too have experienced the looks of bewildered amusement and the distinct realization that you're probably just getting old. Well before you put yourself out to pasture, or consider putting your beloved record collection up for auction on eBay, there are a few things you should know. A recent resurgence in vinyl records fueled by collectors, vinyl DJs and music enthusiasts who can't seem to find their favorite oldies on iTunes has paved the way for new products that merge one of the oldest audio achievements of the 20th century with the digital advancements of today – the turntable and the USB port.

Even those who have never worked with film sometimes long for the shooting techniques & aesthetic effects lost in the transition to digital video. Thankfully, some of that lost magic is being returned to our craft with devices like 35mm adapters, which allow you to marry a 35mm SLR camera lens to a video camera.
