AV RECEIVER BUYING TIPS

Putting together a home theater can seem like a daunting task. So many pieces to think through and connect up! But if you care enough to do your homework and educate yourself, you’ll find it’s not as complicated as it looks. Here’s what goes into your typical viewing room.

Of all the components in your home theater system, none gets more playtime than your audio/video receiver. But buying an AVR can be daunting for home theater newbies or even seasoned enthusiasts diving back into the upgrade pool. AVR technology and features have been constantly moving targets these last few years. Here are some basics to help you make your selection, circa 2012.

A/V What?
An A/V receiver combines three audio components in one box. Primarily, it performs the traditional roles of a preamplifier and power amplifier. The sound for any home theater begins as a relatively low-level audio signal coming off a source component such as a cable box or disc player. These days, it’s more likely to be a digital audio signal than an analog signal. That signal gets converted between digital and analog as needed, manipulated to affect your volume adjustment, and might perhaps have some bass and treble contouring (or more sophisticated equalization) applied before it’s sent to the power amplifier, whose only job is to pump it up to the power level necessary to drive your speakers to sufficient volume.

It’s easy in this brave new world of Ultra-Uber-HDR-4K HDTV to forget that the sound is still half—yes, half—of the home theater experience. Even if you’re actually smart enough to know that, and you wander into your local big-box electronics store in an effort to improve upon the tiny rear-facing drivers that pass for flat-panel TV speakers, you’re probably in for a knee-deep wade through soundbars and Bluetooth speakers before you stumble onto the audio/video receivers. You remember receivers: Those boxy things? Bunch of buttons and knobs and lights on the front? At one time, people used to called them stereos? “Oh yeah...those,” says the young skeptic festooned with the store logo on his shirt. “I think we still carry a couple of them in that back room over there.”

Selecting audio components is one of the more daunting tasks that any serious home theater enthusiast faces. On the surface, it seems evident that if you just go out and buy the best components you can afford, they’ll sound great with both movies and music. And that’s generally true: A better system will more accurately reproduce the waveforms you feed it, irrespective of whether they come from a movie or music. But it’s often not that simple. While assembling a home theater system that’s equally spectacular with movies and music may be a laudable goal, unless you have unlimited funds, you’ll probably have compromises to make. At that point, you might want to steer the system’s performance strengths one way or the other with the right mix of speakers and electronics. But how do you go about matching these up?

Basic Surround Decoding
Today's AVRs feature a ton of surround decoding features from Dolby and DTS, from basic 5.1-channel surround decoding to several ways of decoding stereo into 5.1-channel surround, or beyond.

Are You Ready for the Heavy Artillery?

A friend who went to college in the late 1960s told me that everyone in his dorm fell into one of two absolutely opposing groups: those who blasted the Who’s Tommy and those who were mesmerized by the Beatles’ White Album. Or for the sticklers among you, the album nicknamed the White Album but officially known as The Beatles. I could entertain you with a few more sentences’ worth of metaphor, but you get the idea. You say tomato, I say tomahto.
