DVD-Audio: The long and winding road to the future of music?

DVD is a hit. Lauded as the most successful format launch since—well, I guess nothing has had this overwhelming level of acceptance in a long, long time. I wish I could say the same about DVD's younger sibling, DVD-Audio. Introduced three years ago, it's just now starting to gather some momentum. On the hardware side, DVD-Audio offerings run the gamut from saucy little $200 players to budget-busting state-of-the-art machines. New DVD-Audio titles are still just trickling out, but even a cursory glance at a typical disc's fairly lengthy production credits might explain the relative paucity of releases. I counted 13 DVD-Audio-related producers, engineers, and mixers on R.E.M.'s Reveal disc and a crew of 21 on Queen's epic A Night at the Opera. Releasing a DVD-Audio reissue or brand-new title is a labor-intensive effort.

A sharper, wider view of the current sports action and what you can expect in the future.

High-definition television isn't just about movies. Another killer app is making the case for an HDTV in every home: sports. Highfalutin videophile talk about the ability to see what the director intended pales beside the sports fan's visceral need to follow the ball and watch the action develop. Sports bars are where many fans get their first taste of sports on HDTV. The falling price of HDTVs has created the irresistible urge to bring the experience home. Plus, at home you can add a good surround sound system. A Dolby Digital 5.1 soundtrack that captures the roar of the crowd only adds to the excitement.

Our first look at Ultra 2 and the first certified system from Snell and Pioneer.

It may be time to start asking the question that's asked of all pastimes with hobbyist roots when their popularity surges: Is home theater a permanent cultural phenomenon or just another fad destined to burn out before its time? Recent evidence certainly shades the former. DVD-Video has been the catalyst for an unprecedented boom in the popularity of home theater and should probably be credited with completing home theater's undeniable transition from novelty act to mainstream entertainment that began with Dolby Surround and the first inexpensive multichannel speaker system. But is home theater a cultural phenomenon the way that the computer is a cultural phenomenon? Do a majority of Americans actively seek to make it a part of their lives day in and day out? Not yet—but home theater's high-water mark is still to come.

Determining amplifier-power requirements for your home theater system.

Power output is often the biggest selling point for receivers and standalone amplifiers. Bells and whistles aside, you can often spend a lot less money for an amplifier or receiver that has a lot less power. While there are several factors that influence an amplifier's sound quality, we're not going to go into many of them in this article. We're going to focus on power. Ideally, an amplifier should be rated with low distortion, measured over the entire audible frequency range and with all channels driven. You should always listen to an amplifier before you purchase it. Whether you should test the 60-watt model or the 150-watt version depends on many factors, including your listening environment, the speakers you'll be using with it, and your listening habits.

The ins and outs of A/V connections.

Anyone who's looked at the back of a new, high-end TV or receiver and gazed upon row after row of ports knows that there just might be too many ways to connect other devices. Believe it or not, more inputs are going to become commonplace in the next few years (a number of high-end TVs already have seven video inputs in four different formats). Whether you fall into the category of those who are just discovering the merits of S-video or those who like to argue the merits of their projector's five-wire RGB inputs, the number and type of connections, ports, and inputs has exploded in the last decade, and it isn't going to get any simpler in the next few years.

The basics of bass management.

Bass: It is undoubtedly the most misunderstood aspect of a home theater system's performance and, in some ways, the least appreciated—especially among the higher-end ranks. Bass' bad rap (no pun intended) derives from a number of sources, but its fundamental undoing is its poor implementation in the vast majority of audio systems—from the genius who cruises around with 10 $50 monotone subwoofers in the trunk of his car to the home theater owner who hasn't put forth the considerable time and effort it takes to properly calibrate low-frequency output. Poor-quality subs, of which there is no shortage, are as much to blame in this situation as user error. The bottom line is that quality bass performance is critical to any audio, music, or home theater system, and its journey begins long before the signals ever reach our speakers.

A three-step guide to receiving HDTV signals.

You used to be able to buy a TV, plug it into an antenna or cable outlet, and start flipping channels. It was an amazingly simple system. Digital television and its high-resolution subsystem, high-definition television, aren't quite as plug-and-play . . . yet. Antennas only pick up high-def signals in some markets; cable usually doesn't pick them up at all. Satellite seems like a good bet, but it doesn't offer everything. Plus, certain DTV tuners don't work with certain displays. It's enough to drive any self-respecting videophile to drink (not that we'd fault you for that). But there is hope. The following three-step guide is intended to make setting up an HDTV system easier than following that other multistep program. First, figure out what sources are available to you, then find a tuner that works with those sources. Finally, buy a high-definition display that works with that tuner.

Feeding the Beast and Chasing Its Gremlins : A basic guide for harnessing AC power.

There's absolutely nothing worse than putting together an awesome home theater system that's starved for power or buzzing with ground loops. We often take electricity for granted, assuming it will be there when we need it. Unfortunately, that's not always the case. You don't necessarily need an electrician just to connect your audio and video system, but you may need to check out your electrical system before you spend hours, if not days, connecting all your components. The two things you should consider are whether your system is getting enough power and if your components are connected to that power system correctly.

Part two in our high-resolution-audio series introduces SACD and DSD. The CD is dead. Long live the super CD.

You must allow me a bit of hyperbole for the sake of a powerful opening statement (which, as I assume they say in journalism school, is important). The truth is, the CD is about as dead as the analog television, which means it's alive and kicking just as it has always been. Still, the writing is on the wall for both formats. While the CD can at least take consolation in the fact that it doesn't have government mandates guaranteeing its demise, the future of audio has most definitely arrived (as with television) in the form of high-resolution. Let's not forget multichannel, either. While the hard-core music lovers are salivating over the potential of high-resolution, most are well aware that popular acceptance in America usually requires the new and different to be as big and flashy as possible. On many systems, the multichannel format is undoubtedly going to represent a more-noticeable change in the way people listen to music.

The truth behind progressive-scan DVD players.

Conspiracy theories are like computer problems—almost everyone has one. From JFK's assassination to the demise of TWA flight 800, it's rare that everyone will accept the simplest explanation as the truth. Consumer electronics has its fair share of conspiracy theories, as well. They may not be as complex as a Louisiana district attorney's triangulated-bullet-trajectory theory, but they exist, nonetheless. What do you expect to happen when a large number of obsessive-compulsive personalities have too much free time and join a chat room?

The world's most complete guide to DVD-player features.

If you're thinking of buying a DVD player, the number of features most players offer might overwhelm you. Sure, you know the basics: DVD is the hottest thing since the first time man invented something round. It consists of a disc the size of an audio CD but with 10 to 15 times more storage capacity. The disc has enough room to store a full-length motion picture with a digital picture that's better than that of laserdisc or satellite broadcasts. A progressive-scan DVD player connected to a widescreen TV can even approach the quality of high-definition television. The digital audio can include up to five full-range, discrete (meaning separate) channels with one LFE, or low-frequency-effects (aka the .1), channel for impact. The best part is that DVD players and movies should be compatible with your current system, no matter how archaic it is. You can buy a DVD player now and almost certainly enjoy the benefits right away, and you can upgrade various parts of your system and glean even more performance from the DVD software that you'll undoubtedly start collecting. What you really want to know, though, is what features to look for in your first/next DVD-player purchase. As usual, we're here to explain them to you. We've also included a couple of tips on how you can take your DVD/home theater experience to the next level.

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.

Last month, we explained our speaker measurements. Now, senior technical editor Mike Wood tackles the intricacies of video-display measurements.

It's only fitting that our video measurements be displayed in an obscure, almost-illegible triangle. Three-sided geometric shapes have always been somewhat mysterious objects, implying power or fear. Our measurements can do both. In this, our second attempt to explain to you, our faithful readers, what the ancillary boxes labeled "HT Labs Measures" mean, we'll discuss what our detractors call the triangle of death, why we use it in our display measurements, and what it means to you.
