After Neural-THX Surround got around 14.5 minutes in the limelight with its Super Bowl XLII showing earlier this year, the technology has remained far, far away from the press. Now, however, SPEED is vowing to integrate Neural-THX Surround professional products "for its HD programming schedule covering NASCAR, Grand Am, IndyCar, etc." For those unfamiliar with the technology, it goes a little something like this: 5.1 sound from the track is taken in, beamed over stereo channels to minimize bandwidth usage and then decoded by specially equipped receivers for "5.1 surround" in the living room. From what we can tell, the tech should be ready to roll right now, so it's up to you to snatch up an AVR in order to take advantage.

Yamaha cranked out its pricey YSP-600 sound bar just a few months back, but the company's already looking to put the past behind and move forward with the YSP-3050. The latest in the outfit's long-standing line of Digital Sound Projectors offers up 21 beam drivers, two woofers, 23 corresponding digital amplifiers, three Cinema DSP programs (movie, music and sports), analog-to-HDMI video upconversion, HD upscaling to 1080i / 720p and a 1080p (24Hz and 60Hz) compatible HDMI interface with two inputs and one output. Aside from engulfing you in audio with just a single bar, the unit is also XM Radio / iPod-ready (via the $99.95 YDS-11), and the integrated FM tuner and bundled remote make it even easier to see in your den. You'll also find the firm's propriety automated system calibration (IntelliBeam) along with TV Equal Volume to keep those sudden bursts at bay when it comes time for commercials. 'Tis a shame this piece costs $1,399.95, but if you're tight on space, it just might be worth it. Full release after the break.

It's too early to tell if gold-colored components really are making a comeback, but you better believe Onkyo's at the forefront of the gilded parade. Shortly after pumping out the TX-SA606X in Japan (and the TX-SA606 in America), the TX-SA706X has arrived to take things one step further. This 7.1-channel receiver delivers a potent 200-watts of juice to each channel and includes five HDMI 1.3 inputs (alongside one output), a frequency response of 5Hz to 100,000Hz, Audyssey Dynamic EQ processing and built-in decoding for Dolby TrueHD / DTS-HD Master Audio formats. Granted, such a monster of an AVR won't become your very own with putting a nice size dent in your wallet, but those in Japan can treat themselves on July 19th when it lands for ¥189,000 ($1,781).

We've seen a few HTIB systems trickle out from the Pioneer labs of late, but never four at once. Today, the firm has made official a foursome of home cinema systems slated to hit Europe in the fall, so we'll cut right to the chase. The LX03 is the lone system with a DVD / SACD player and USB port, while the others thoughtfully include Blu-ray decks. The LX03BD (satellite speakers included) and LX08BD (no satellites included) feature 500-watts of power, HDMI 1.3 sockets (2 in / 1 out), KURO LINK, an iPod connection and a 7-band equalizer. The LX01BD includes omni-direction speakers, 400-watts of power and pretty much everything else found on the LX08BD. For complete specifications, be sure to give the read link a visit; as for availability, you'll find the LX03, LX03BD and LX08BD systems in October while the LX01BD arrives in November.

Earlier this month, ASUS introduced the "world's first HDMI 1.3a compliant audio / video enhancement combo card." Who knew numero dos was so close behind? Auzentech has just announced its very own HDMI 1.3-native PCIe audio combo card, which is built around Creative's X-Fi processor and enables PC users to easily output 7.1-channel audio with no downsampling. Essentially, the Auzen X-Fi HomeTheater 7.1 "accepts video from either an internal or external connection, mixes it with digital audio, and outputs the combined video and lossless multichannel audio via a single HDMI 1.3 port." Yep, that means Dolby TrueHD and DTS-HD Master Audio codecs are fully supported. The only digs? For one, pricing remains a mystery, but the real kicker is the September release -- talk about a long wait.

Looks like one of those "souped-up" set-top-boxes could be just what the doctor ordered for ailing U-verse users. It's no secret (not even to AT&T) that many customers have been experiencing intermittent audio dropouts using optical audio connections on the current Motorola STBs. Typically, the glitches occur every 30 seconds to a minute, and the problem seems to reside within the box itself. Reportedly, Tier 2 technical support has advised some subscribers that Cisco boxes are now being dispatched for those dealing with the issue, and of course, AT&T asserts that these units will solve the problem. The latest word on end-user availability is "within [a few] weeks," so hopefully a bona fide fix isn't too far out.

Sure, it's easy to get a great sounding system when money ain't a thang, but what if you're on the hunt for a 5.1-channel surround sound system from a company you've heard of in the last decade... and you've only got $50? Enter JVC's SXXSW6000, which is being sold now at Wal-Mart for a staggeringly low $49.88. The critics over at Sound & Vision actually took the plunge and decided to put the incredibly inexpensive system through the paces. Miraculously, reviewers found that the system wasn't nearly as bad as one might expect, even proclaiming that it was "definitely worth $50." Still, the kit had its flaws, particularly when trying to handle loud explosions, throaty voices and any manner of bangs / crashes. All in all, S&V couldn't really knock these guys considering just how cheap they were, but they still recommended that you hold off and save up until you could throw a few Benjamins on a real system.

Home theaters have almost always been a balance between usability and experience. On one had having surround sound while watching TV is much more enjoyable, but at the same time trying to explain to the significant other how to turn it all on can be a nightmare. And in the spirit of a solution, William writes in:

"I've been thinking that the next TV I bought would be the center of my system, with all of the HD inputs connected directly to my TV and the TV feeding digital sound to my multichannel Dolby Digital decoding amplifier. Then I noticed that the TVs SPDIF output doesn't work with HDMI inputs. This seems to me that it's negating the entire purpose of HDMI, using one simple cable. If I connect my DVD player to the TV using HDMI then I don't want to have to string a separate digital cable from my DVD player to my amplifier. I want to connect my TV to my amplifier once, and just use the power button and volume controls on the amp. Is this sort of thing common among TVs with digital sound outputs? Is it some copy restriction issue with the HDMI stuff that the digital sound can't then be shipped to a separate output?"

Unfortunately this is very common and we've heard the DRM excuse on this one a few times -- but who knows if it's true. The fact is that the receiver has been the junction point of the HT system for years, and even with HDMI it continues to be. The good news is that if you play your cards right you can still have one remote (non universal) that easily controls everything. The trick is buying equipment -- which might mean replacing what you already have -- that supports HDMI-CEC, and works well together. Using HDMI-CEC, the receiver's remote can send signals to the HDTV via HDMI to let it know when to turn off and on. Furthermore, you Blu-ray player can tell the receiver to change inputs when it is turned on, etc. The bad news is that although HDMI-CEC is a standard, most manufacturers only guarantee compatibility with their products.

Turns out that not everybody is lawyer-angry with Vizio right now. The company has entered a partnership with SRS Labs that will give it access to SRS's portfolio of audio technologies. Fruits of the partnership will start showing up in Q2 of 2008, when Vizio starts making SRS TruSurround XT available in three models: a 42- and 46-inch LCD, and a 50-inch plasma. Not exactly new, TruSurround XT is all about virtual surround sound; that audio we sometimes find phasey and unnatural to the point where it decreases our involvement with the content. But Vizio and SRS have data to back up their strategy: a Consumer Electronics Association poll showed that 76-percent of all flat panels are used without any external audio. We're used to being a minority opinion, but we don't understand the widespread fear over multiple discrete speakers in the room, especially with the rash of stylish HTIB systems now available. If you're in that 76-percent crowd, we suppose virtual surround is better than mono; but you're missing out.

If Sony's diminutive new HT-IS100 HTIB is still too large for your hole in the wall, the HT-CT100 is probably your last hope at "surround sound." The sound bar itself is designed to be mounted beneath one's flat-panel and packs a trio of drivers which receive 50-watts each. As for the subbie, it gets a respectable 100-watts of its own. The system handles Dolby Digital / Dolby Pro Logic II / DTS signals and comes with three HDMI / optical digital audio jacks, a coaxial digital audio port, analog audio connectors and a remote to boot. Not a clue if this one's coming to America (though we have all ideas it will in time), but those in Tokyo can snag one in mid-July for ¥50,000 ($491).

Update: Seems this one's new for Japan only.

No sooner do we ask about just how many readers actually give a hoot about multi-channel audio, in comes this. Considering the plethora of folks in the exact same situation, we knew right away it'd made a beautiful Ask Engadget HD question. Without further adieu:

"I recently splurged on a hot new plasma, but now I am looking for a surround sound system to complete the joy. My issue is that I currently live in a rental property, and don't have the luxury of poking holes in walls to set up my system. I know there are a few options out there for people in my position (sound bars, wireless rear speakers, PowerLine?) but I have no idea which gives the best surround sound result. I was looking to spend no more than $2,000."

We'll be honest -- almost anything is possible at $2,000, unless that includes the price of a few (very) nice drivers. We've seen solutions from Rocketfish and a slew of other companies that essentially enable users to add two rear surrounds sans wires when running cabling towards the back proves problematic, but often these are underpowered and flaky at best in actual use. Let us know what you've found to be superior in comments below.

With all this focus on HDTV of late, we've been wondering if high-def junkies care nearly as much about their audio as they do their video. Sure, we know video trumps audio in the general public's eye, but we're talking home theater freaks here. Folks who make a point to hang up sheets to eliminate light from a room. Folks who take a vacation day just to calibrate their TV -- you know, people like yourself. Toss your vote in below and feel free to elaborate on your audio setup (or lack thereof) in comments below.

Rest assured, NBC isn't taking this year's Olympics broadcast lightly. After announcing that some 3,600 hours of the games would be shot (with many in HD), we've now learned that the network will be broadcasting the 5.1 surround mix and stereo mix simultaneously. According to Bob Dixon, NBC Olympics' director of sound design, 2008 marks "the first time the games will be produced totally in high-definition with 5.1 discrete channels of audio," and the plan is to send six discrete channels to those capable of receiving it and carefully downmix for those with stereo capabilities. Needless to say, there's going to be extensive work happening behind the scenes in order to pull off such a feat, and if you're the technical type, feel free to tap the read link to get a sense of just how elaborate the setup will be.

With all these companies honing in on bringing HD capabilities to handsets, we were beginning to wonder when someone would step up and lend a hand on the audio front. Thankfully, both Dolby and SRS Labs have come forward at Mobile World Congress to announce separate enhancements to mobile audio, so we'll touch on the former first. Dolby Mobile, hailed as an "audio processing technology platform that brings rich, vibrant surround sound to music, movies, and television programs on mobile phones and portable media players," is available as we speak on the FOMA SH905i and FOMA SH905iTV in Japan, but will hopefully float out to other handsets in due time. As for SRS Labs, it's boasting its own SRS CS Headphone technology, which reportedly "takes stereo or surround encoded 2-channel audio and processes it using an ultra-low-power Circle Surround decoder to create 5.1 highly accurate channels." Granted, we're still wondering exactly how 5.1 channels make their way though stereo earbuds, but we'd be up for a listen, regardless.

It's not often that we'll take time out to cover a single chip, but when said chip can handle "streaming of up to eight different concurrent single streams or four bi-directional streams of HD audio," we figure it's worthy of a mention. The STS DARR81 allows HD audio to be both transmitted and received with a single device simultaneously, and it also supports "5.1 and 7.1 surround sound, headphone and multi-room applications at the same time." Currently, we're not exactly sure what types of electronics will be housing these in 2008, but a slew of gear based on STS' technology will reportedly be showcased (and peeked by us) at CES next month.
