A lot of consumer electronics editors and reviewers have a love-hate relationship with product ratings. The love side comes from knowing they make readers happy. Assuming the ratings structure is well thought out (that is, simple and easy to understand) and the ratings are applied with fairness and accuracy, they wrap the whole product up in a nice little ball and tell you, at a quick glance, whether it's a winner, loser, or in-betweener. Perhaps most important, a good rating, or a good rating coupled with a seal of approval like our Top Picks designation, is validation that the product is worthy of the money you plan to spend on it. Given the sea of black boxes, identically thin TVs, and similar speaker systems out there, we recognize that giving you this validation is really the essence of our job at Home Theater.

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.”
