At first look, RCA’s Mobile TV Tablet is just another one of the many Android tablets on the market. But beneath the tablet’s eight-inch (1024 x 768) screen is what RCA claims is the “world’s first” dual-tuner mobile TV. In addition to a standard over-the-air DTV tuner, the new tablet includes a Dyle mobile TV-compatible DTV tuner that provides access to around 130 mobile TV stations in 35 markets around the country. (The built-in mobile DTV tuner also receives mobile digital TV channels from broadcasters not affiliated with Dyle. You can see if there’s a Mobile DTV station in your area here.) The multifunction tablet includes a built-in telescoping antenna, Wi-Fi connectivity, dual cameras, and GPS functionality. The tablet (Model DDA850R) has a battery life up to four hours in mobile TV mode, or up to 10 hours when web browsing. It will be available this Spring with a suggested retail price of $299.

LG's BH9430PW all in one home theater system may be a bit (OK, more than a bit) less ambitious than some of the components we discuss in this report and review in the pages of Home Theater, but for many folks it's all they think they can afford (which is not always the case). It's said to be a 9.1-channel system, but I saw only 5.1 channels in the demo. The small speaker cones use Kevlar, a material long used in some very high-end speakers. B&W, for example, began using Kevlar for some of its drivers in the mid 1970s. I didn't get to hear the LG system; the demo began with a far too loud (for me and the system) crash, boom, bang action scene and I was out of there like a shot.

HiFiMan is introducing two in-ear headphones aimed at “audiophiles on the go” and a high-performance portable music player at CES. The RE-600 “Songbird” ($399) and RE-400 “Waterline” ($99) earphones use custom-designed Titanium-coated drivers, neodymium magnets and premium cabling. Both are due out in the coming weeks.

The flagship HM-901 music player ($999) is slimmer than previous models, has a simplified user interface, and accepts most lossless audio formats, including Apple lossless. It uses 32-bit DAC chips and accommodates 24-bit/192 kHz upsampling. The player will be available in March with an optional $399 docking station to follow in April.

Here's a front shot of the Theta Supernova preamp-processor covered in an earlier blog. It should sell for around $10K, just a bit more than half the cost of a fully configured Theta Casablanca. The only open question appears to be if the Supernova will offer the same advanced room correction that will grace the Casablanca. My vote is yes, it should.

You just never know who or what you’re going to run into while walking the show floor…

Dancing Robots: Tosy’s mRobo Ultra Bass is actually an MP3 player with a built-in speaker. When the music starts to play, the little guy turns into a dancin’ fool with some serious moves. Best part: Watching his head pop out from his chest when the music starts (mRobo is a mere torso before he springs into action).

And then there's...

"Blue" and "Air" has become our notebook slang for products including both Bluetooth and AirPlay wireless capability. There are quite a few of them at this CES. HRT, a new company, features them in the Stage speakers, with analog amplification, preamp, and USB DAC built into a separate module. One-inch tweeters are treated fabric, 3.5-inch woofers are aluminum, and the system sounded fabulous with CD-resolution files of Miles Davis' Kind of Blue (and we think it could have sounded even better with a 24-bit file). The price is $999 with Blue and Air or a hundred bucks less without—but why would you do that? Shipping in June.

DTS offered one of the show's more interesting audio demos with DTS Headphone:X. The audience were given Sennheiser headphones selling for roughly $100. With headphones off, we heard an 11.1 channel check with front, front height, center, side surround, back surround, and back surround height channels (not including sub). Then the channel check was repeated with headphones on. It sounded precisely the same and the sound still seemed to be coming with the speakers. Finally we were invited to hear the channel check while removing and replacing the headphones. At this point it became clear that the sound was coming only from the headphones. The steering was impressive, with the side, back, and height channels occupying their places in the soundfield with the same confidence as the front channels. DTS also did an A/B demo of the Vizio VHT215 2.1-channel soundbar with various technologies acquired along with SRS Labs. Even amid the noise of the show floor, it was clear that what is now called DTS TruSurround (formerly SRS TruSurround) was lifting the soundstage clear of the bar's physical limits. Just a little, but enough to be noticeable.

Panasonic and Sony have teamed up to produce OLED panels using a (presumably more productive and thus likely more economical) printing technique. If successful, the company's will share panels though go their own way on electronics. Should be interesting to watch. This 4K, 56-inch Panasonic OLED did look fabulous. Of the OLEDs on display at the show, only Sony's and Panasonic's were 4K.

Lantos Technologies demonstrated how simple and relatively discomfort-free it is to take an impression of the average person’s ear canal with their new 3D digital ear scanning technology. Taking an accurate and complete impression of the ear canal is incredibly important when it comes to making custom earpieces for hearing aids, noise protection, and custom audio (i.e., high-performance earbud-style headphones). The traditional process of taking an ear canal impression involves examining the ear canal, inserting an otocblock into the ear canal to protect the tympanic membrane from harm, and then filling the ear canal with an pliable impression material that takes about five to ten minutes to solidify before it can be removed. (Sounds like fun, doesn’t it?) The Lantos technology uses
emission re-absorption laser induced fluorescence (ERLIF) [and] was developed by Dr. Douglas Hart at the Massachusetts Institute of Technology. Using the intensity measurement of two different wavelength bands of fluorescent light as they travel through an absorbing medium, ERLIF generates a highly accurate 3D map. The medium selectively absorbs one wavelength band over the other, thus the intensity ratio of the two wavelengths as they travel through the medium can be measured using a standard camera…
During a sparsely attended press conference at CES, Lantos representatives demonstrated the process using the Lantos Scanner, which is a small, handheld device that includes a fiberscope enclosed in a conforming membrane. Once gently inserted in the ear canal, the membrane is expanded and conforms to the shape of the ear canal. As the fiberscope is retracted, it creates a 3D image of the ear canal in real time – with the entire process taking less than two minutes per ear. The resulting scan is typically much more accurate than the standard impression technique provides and has the advantage of immediately being available as a digital data file that can be sent electronically to a manufacturer.

Currently it’s somewhat expensive (>$100), time-consuming, and often uncomfortable to go to an audiologist who can make a custom ear canal impression which can be sent to an earphone manufacturer (such as Etymotic) in order to create an individually customized earbud insert. Once FDA-approved in the US, the Lantos 3D Digital Ear Scanner promises to make customized earpieces much more widely available.

On the video side, CES is a flat screen HDTV-fest, not a projector show. Nor is home theater a common site at the audio-centric Venetian Hotel exhibits, dominated by expensive 2-channel audio. But I was delighted to come across at least one superb audio/video setup. The new Gray Wolf is the latest 3D LCOS projector from Wolf Cinema, and at $8000 the company's lowest price projector to date. It looked amazing--and amazingly bright on a 132-inch wide, 2.35:1 Screen Innovations Black Diamond 0.8 gain projection screen.

The program material I viewed included the latest Mission Impossible flick (from Wolf's collection) and scenes from Prometheus. The latter was one of the three discs I had brought to the show (which also included Thor and How to Train Your Dragon. I was surprised to see a bigger crowd in the room when the selections were finished than before--given the 2-channel-centric leanings of most of those who visit the exhibits at the Venetian. (All of my choices, by the way, were based primarily on their music and visuals, not their action.)
