Eating better, exercising more and quitting smoking may be the most common New Year's resolutions, but what about some ideas for our home theater and audiophile readers? Here are some resolutions to increase your knowledge and enjoyment of your home theater and audio systems in 2009. We would also love to hear what your audio/video related new years resolutions are, so leave us a comment at the end of the article.
Learn About Video Calibration and have your HDTV calibrated
When the average consumer walks into a big-box AV retailer, trying to pick out a new set from the wall of HDTV displays can be intimidating. Determining which set has the best picture in the store can be like finding a needle in a haystack. Not only are the lighting conditions, with bright fluorescent lights, less than optimal, chances are the source content being fed to the sets is poor at best and most likely the sets were never calibrated. With salespeople who often have little or no knowledge about video calibration, consumers often simply pick the set that looks the brightest.
Brightness, contrast, picture, edge-enhancement; these are terms you have probably seen on the menus of your TV but do you actually know what they mean? Sure you probably have a general idea, but did you know there are classes you can take to learn exactly what they mean? The Imaging Science Foundation (ISF) is a group that provides educational seminars for consumers and certification programs for those who wish to be professional video calibrators.
If you have a front projection, rear projection, LCD or plasma, having your video monitor professional calibrated can not only provide you with a stellar picture, but in many cases can extend the life of your set, which can easily pay for the several hundred dollars you can expect to pay for a professional calibration. Rear projection sets, although not being manufactured by many companies anymore, have a lamp in them that burns very hot. When a new set comes out of the box, it is often much too bright so it can look good next to the other TVs at the store. When you get it home and are watching in a darker room, the resulting picture is too bright and a great amount of fine detail and contrast are lost.
Having the set ISF calibrated will often result in the light output being reduced dramatically. This means the bulb will burn cooler and will in turn last longer. I have seen calibrated rear projection and front projectors last twice as long as comparable sets after being calibrated. Of course individual results will vary. Be sure to never unplug your set without letting the cooling fan fully cool the bulb down, and never touch the bulb as the oil from your skin will make the bulb burn out faster.
Learn About Room Acoustics and have your room tuned
Other than perfectly tuned sound rooms, virtually no room is acoustically perfect. Square corners, windows, sofas, curtains, tile floors and shag carpet are just a small list of things that affect the way that sound travels around a room. There are automatic EQ systems, both outboard and built into receivers, that can analyze the way sound travels around a room and can automatically compensate for flaws in the room. This can be a good solution for some rooms, but there are times when a professional needs to be brought in to analyze the room and then make the necessary changes.
Perfectly flat frequency response is not always the end goal for acoustic spaces. Depending on the type of music you like to listen to, you may want to have a more “live” sounding room with a great deal of reverberation or you might want to have a more muted, and “dead” sounding room. Dead does not always mean bad as some people like to hear how their speakers and electronics sound rather than how the room itself imposes its own sonic character on the music.
Professional acousticians are available to come in to your home or room and analyze your existing set up and suggest changes. These changes can run from simple things like moving your speakers or sofa to expensive solutions like knocking down walls or buying new speakers and gear. Room tuning can be a never ending process that some people love and others find maddening, so you’ll just need to figure out how important it is to you. You just don’t know how good your room can really sound until you explore your options with room tuning.
