We've covered just about everything you need to know about the PS3 Slim, but the sleuths over at Engadget HD (via a translated version of AV Watch) found a chart that indicates the PS3 Slim can bit stream both Dolby TrueHD and DTS-HD Master Audio. That change actually isn't that surprising, since the original limitation on the "old" PS3s was due to an older HDMI chipset; newer HDMI outputs have no problem bit streaming the high-resolution soundtrack formats.

We have a PS3 Slim review sample onhand, so it was easy to confirm the rumor. We had … Read more

In the beginning of recorded sound, there was mono. One speaker, period.

Mono speakers were plopped wherever it was convenient, and that was that. Consumer audio remained strictly mono until the late 1950s with the introduction of stereo tape and LPs. Now you needed two speakers.

Home theater upped the ante to 5.1 channel surround sound--five speakers, plus a subwoofer--and setup hassles were getting tricky. Dolby's Web site offers very specific requirements for the placement of the front left, center, right speakers, and the side surround speakers. 6.1 and 7.1 systems add rear surround speakers.

It's one thing to look at a diagram, but your room probably doesn't look like the diagram. Reality sets in, so very few 5.1, 6.1, or 7.1 system buyers get remotely close to the recommended speaker placements.

I've seen countless 5.1 home theater in a box systems in real people's homes with all five satellite speakers clumped in a row under or over the TV. Some buyers spread the speakers out across their entertainment furniture, still with all the speakers in front, near the TV. Obviously, those people don't want to string wires across the room. I don't blame them.

On one hand it'll sound "fine," but the envelopment the film sound mixers worked so hard to achieve will be lost. Don't worry, the Dolby Police won't arrest you for improper placement and the certain destruction of the filmmaker's intent.

If you have all of your speakers sitting in a pile, but I've made you a little curious, temporarily move the surround speakers out into the room. Put 'em on something to get them off the floor: A chair, bookcase, furniture, and so on. Play a few big action flicks and see what's up with surround. It might surprise you and just maybe you'll be inspired enough to make the effort to find permanent, around the room locations for the surround speakers. Hey, in 5.1 it's only two skinny wires.… Read more

Dolby has a new surround format: Pro Logic IIz.

Here we go again. Another new format with more speakers, but this time, the "surround" speakers are in the front of the room, three or four feet above the left-and right-main speakers. These height channels are designed to provide a greater sense of envelopment than previous generations of Dolby or DTS surround.

Pro Logic IIz incorporates all of the features and capabilities of Pro Logic IIx.

"Expanding on established Dolby Pro Logic II matrix-decoding innovations, Dolby Pro Logic IIz identifies and decodes spatial cues that occur naturally in all content--stereo and 5.1 broadcast, music CDs, DVDs, 5.1 and 7.1 Blu-ray Discs, and video games," the Dolby site further explains. "Dolby Pro Logic IIz processes low-level, uncorrelated information--such as ambiance and some amorphous effects like rain or wind--and directs it to the front height speakers."

You don't have to buy new, specially encoded discs to experience Pro Logic IIz, but do you really want to buy another pair of speakers, wall-mount them, and run a pair of speaker wires up your wall, to the sides of your TV?

Dolby doesn't require the height speakers to be identical to the main-left or -right speakers. Some Pro Logic IIz systems will use a total of nine speakers (five front, four rear), plus one or more subwoofers.

Onkyo's TX-SR607 ($599 MSRP) is the first receiver to feature Pro Logic IIz; the company will soon offer additional models equipped with the new Dolby processor, to be announced later this year.

Then again, Yamaha's higher-end receivers have had height, aka "Presence," channels for years. Those extra speakers supplement the sound from the front speakers with ambient effects produced by Yamaha's proprietary Cinema DSP, which provides various multichannel configurations up to 11 channels. Obviously, Dolby's Pro Logic IIz uses different technology, though the end result may be similar. … Read more

While the rest of tech world was busy scouring news from CES 2009, Samsung's duo of Netflix-enabled Blu-ray players--the BD-P2500 and BD-P2550--received a firmware update to enable onboard DTS-HD Master Audio decoding. The players were promised the update "by the end of the year", but chalk it up to another delayed Samsung firmware release, as we've seen before.

The firmware is available for download from Samsung's site, and the players can be updated via a direct download using an Ethernet connection, or, for players not connected to home networks, users can download the file to … Read more

DETROIT -- The future sweet spot for Buick's car line will be the mid-sized segment, the top executive for General Motors' Buick-Pontiac-GMC sales channel says.

The full-sized-car segment "has declined 35 percent this calendar year. Bringing more entries into a declining segment wouldn't necessarily be smart," said Susan Docherty, vice president of Buick-Pontiac-GMC.

Sales of the full-sized Lucerne totaled 50,799 in first 11 months of this year, a 34.1 percent drop from the year-ago period.

Buick's spotlight on the car side will be aimed at the redesigned, mid-sized 2010 LaCrosse, which debuts next … Read more

Samsung has put out some pretty good Blu-ray players, but the company needs to setup an RSS feed to keep buyers up to date with the constantly changing firmware plans. We got a note from Samsung this afternoon explaining that the firmware update adding DTS-HD High Resolution decoding to the Samsung BD-P1500, BD-P2500, and BD-P2550 has been delayed until the end of the year. That means owners will have to live with standard DTS soundtracks for a little bit longer if they don't own an HDMI-compatible receiver with onboard decoding for DTS-HD Master Audio.

On the upside, Samsung … Read more

You bought an audio-video receiver a couple of years ago, and now you're wondering whether it's time to trade up and get a model that features Dolby and DTS' new lossless codecs, TrueHD and Master Audio, respectively.

Judging by the numbers they should sound markedly better than standard Dolby and DTS, but according to a recent article in Home Entertainment magazine, the sonic differences were small to negligible. You can read the full article here.

David Birch-Jones and HE's editor-in-chief, Geoff Morrison, visited Dolby Laboratories and DTS' headquarters to listen to the new formats under ideal conditions, comparing them to standard Dolby and DTS. Birch-Jones and Morrison were hard-pressed to hear significant differences.

I have limited experience listening to the two contenders, and I never managed to do speedy A-B comparisons. That said, from what I've heard, I thought that TrueHD and DTS Master Audio were better than the older formats, especially in the areas of imaging, spaciousness, top-end detail, and "air."… Read more

Sony wasn't kidding when it said the next PS3 system update was coming in mid-April. Just in time to take the edge off tax day, the version 2.30 of the PlayStation 3 system software is now available for download. As revealed last week, the software update adds DTS Master Audio decoding (to deliver the best audio from compatible Blu-ray movies), as well as a major overhaul of the interface for the PlayStation Store (as explained in the Sony video walkthrough shown above).

The question is: what do you think? Does the DTS upgrade make the PS3 an even … Read more

Sony has announced the details on the next PS3 firmware update--version 2.30, coming mid-April--and the big news for home theater fans is that the PS3 is getting onboard DTS-HD High Resolution and DTS-HD Master Audio decoding for Blu-ray movies. Home theater fans have long lamented that the PS3 could not decode the new DTS soundtracks at their highest resolution, especially since movie studios like Fox have opted for DTS-HD Master Audio on many Blu-ray releases. Without getting too technical, DTS-HD Master Audio offers 7-channels of lossless audio at 96K sampling frequency and 24-bit depths--which means that the sound sent … Read more
