Home entertainment systems have come a long way since you ooh’ ed and ahh’ed because your neighbor had a few pairs of speakers that actually fit flush into his walls. That’s old news now. Even homes in comparatively modest new developments are being outfitted with a full complement of audio, network, TV and telephone wiring. In many developments the builder offers a standard wiring package and various upgrades for additional wiring, speakers, wiring enclosures and even full control systems.

Systems have evolved to include sleek, wall-mounted touch screens that allow simple access to your music and other house functions such as security, lighting, HVAC, and motorized window treatments. A talented programmer can make these systems function with true “one touch” simplicity. It’s almost as if they’re reading your mind.

The touch screen’s advantage is that it can change the control interface to only show what you need at any one time. This affords tremendous flexibility while retaining the simplicity people desire. The touch screen interface is extremely powerful when combined with another technology that has come into prominence recently; the hard disc based media server.
Your CDs are downloaded, or ripped, onto a hard drive. This combination allows your entire music catalog to be displayed on the touch screen for easy searching. You can typically search by artist, song title, genre, or album. Once the desired selection is located, you just touch it on the screen and it begins to play.

These hard drive servers use computer hard drives and modern compression techniques to store phenomenal amounts of music in a simple audio component less than half the size of a 200 disc CD changer. They function just like a typical CD player, not your computer, so they are reliable and easy to use.

Media servers have exploded in popularity recently because of the enormous popularity of compressed music formats such as MP3 and the fantastic array of functionality a disc based system allows.
For those who have, or do, own CD mega changers, a hard drive music server will be like a breath of fresh air.

Access to any song is typically less than a second away. Contrast that to selecting disc 94 in your 300-disc CD changer when you are playing disc 201. With a multi-room audio system, you may be on the other side of your house trying to do this with a keypad or remote control. The wait for your changer to return the disc it was playing then trundle the carousel around to your desired disc can seem like an eternity.

Another advantage is easy cataloging. Most hard drive systems will recognize any CD you insert for ripping and if they don’t, they are connected to the internet for access to a giant database. This they access automatically to gather artist, album and track information. Gone are the days of using a keyboard or remote to tediously enter the information about your CDs into a CD changer. You can also stop worrying about which slot your discs are in. “Let’s see, was Led Zeppelin IV in slot 90 or 190?”
Using a hard drive server frees up your CDs for use elsewhere such as your car, boat or vacation home.

In addition, since your CDs are not locked up in a changer, your collection is able to be enjoyed by many members of the family at once. With a changer, if someone is listening to it, all of the discs inside it are basically off limits. With a changer, not only are your CDs free for use in other locations but many hard drive servers provide multiple audio outputs.

Multiple outputs enable you to listen to different discs in different areas of the house if your system is so configured. For example, one person could be listening to Korn in the rec room while Bach’s Requiem is being played in the kitchen and Dire Straights in the bedroom. With a conventional CD changer, this is impossible.

You can also buy and store music from many online music services and store those on your hard drive server.
Hard drive servers offer advantages over music files stored on a computer as well. Because they function like a traditional audio component, they are easier to use for many people. It is also easier to integrate them with touch screen based home control systems. This will begin to change as the popularity of multimedia PCs such as those running Microsoft XP Media Center Edition 2005 increases.

These units are many steps closer to delivering the long promised “convergence” between consumer electronics and computers. Multimedia PCs, also known as HTPCs [Home Theater PC] function as DVD players, personal video recorders (similar to a TiVO), and hard drive media storage.

They allow storage of digital photos for easy display on your TV or monitor. HTPCs can, of course, browse the net on your TV via your broadband connection. As hard drive storage becomes more economical and compression techniques become better, the storage of HD movies and HDTV programming will become commonplace.

Soon these types of servers and interfaces will become the norm rather than the exception. You’ll think nothing of the amazing array of features offered and the ability to easily access your media collection throughout your home. Once a rarity, media servers, in one form or another, will be found in almost every home.

So you’ve scraped and saved, now you’ve finally gotten together a semi-respectable home theater system. You want even more, but the idea of spending another few thousand on new front speakers doesn’t cut it. What can you do?

There are ways to get the most out of what you have without breaking the bank. There are several areas you can look at to ensure your theater is set up correctly and performing at its best.

Cables and Interconnects - It’s imperative the signals are transferred from your source components to your speakers, going through various components along the way, with the least amount of degradation. Make sure your audio, video and speaker cables are all of good quality and that none are old and corroded. You can use contact enhancer to be sure the connection is really good. If you need any quality cables, check here: http://1touchmovie.com/blockbuster/BetterCables.html
Make sure to use the highest level of A/V connection your system supports. i.e. if you can use a component or DVI video connection from your DVD to your display device then do it.

Calibration - Your video display will definitely not look its best without proper calibration. Manufacturers have a dismal record when it comes to calibrating sets at the factory. Most are TVs designed to look their best on the showroom floor, not in your home theater. In fact, a CRT based rear projection TV can have its life dramatically shortened by improper calibration.

The contrast is invariably set too high to make the set stand out in the showroom environment. This sells more TVs but causes premature tube wear. (That sells more TVs too, I guess) Proper video calibration will correct the problem. I have used Joe Kane’s Digital Video Essentials for years and the Video Essentials laser disc before that. It is a great tool to help you get the best out of your home theater. Pick one up here:

Acoustic Improvements - These encompass a whole host of different things, from acoustically treating the interior of the room, to quieting down your projector. Whenever you lower your noise floor, you effectively increase your dynamic range. In addition, acoustic treatments can dramatically improve dialogue intelligibility, bass response and imaging.

One of the best in the “bang for the buck” category is to put a 1″ or 2″ thick, acoustic panel on the two side walls of the theater to reduce the “first reflection”. The first reflection is the sound that leaves the front speaker and takes a longer path to your ears by bouncing off the side wall on the way. Since it takes a longer path, it takes more time and arrives later than the direct sound that went straight from the speakers to your ears. The net effect is a loss of dialog intelligibility.

To find the correct placement for the acoustic material, sit at the listening position, place a small mirror on the side wall and move it until you can see the front speaker. When you can, that is the spot to center the acoustic panel.

Another, even cheaper, tweak is to optimize your subwoofer placement. For years people have been told “Bass is non-directional. You can put your sub anywhere”. That is, simply, BS. While low bass is fairly non-directional, the tonal quality and amount of bass is tremendously affected by subwoofer placement. A simple trick is to place the sub at the listening position (at ear height), then move around the room (at sub height) until you find the place with the best bass quality. If possible, that’s where you put the sub.

You can build a hush box around your projector to minimize noise from it. Make sure you use adequate ventilation to maintain proper cooling. That cannot be emphasized enough. As a partial measure, without having to build a whole box, you can place acoustic absorption material on the ceiling above the projector. If your projector is close to the ceiling, this will kill the noise that normally bounces off the ceiling and into the listening room.

I hope this gets you started down the path to even more enjoyment from your home theater and saves you some money at the same time.
