Marketing vs Tech…Consumers Need Voice

On any given day you will find a group of engineers or programmers huddling in the back room, sitting in the corner of the coffee shop, or gathering around the most recently divorced individual's kitchen table to plan the next major new company built on breathtaking technology. The hard fact is…we really don't need more technology. What we do need is better application of the technology we have. In fact, it would be fair to say that we probably have enough sound technology available to last us for the next five to ten years. What we need are people to make the technology usable for the rest of us. Technology is important, but what is needed even more is sound marketing/market understanding, ability and practice. We rush insanely great technology/products to market, we get them reviewed/talked about by bleeding edge media techno-writers and the din of noise fills the media. Print, web, blog, radio, TV all cover the insanely great solution and we forecast fantastic hockey stick sales and insane profits.

Playstation 3 Remote Solution Round-up

The Sony Playstation 3 is not only one of the top gaming systems available, it is also widely used as a high-definition Blu-ray Disc player in home theater systems. Unfortunately, one problem with the PS3 is that the unit may not be controlled with the same universal remote you use for the rest of your AV components. The Sony Playstation 3 does not have an InfraRed (IR) receiver which means it cannot understand the commands sent from most universal remote controls. Instead, Sony chose the new Bluetooth protocol exclusively for wireless control. That raises the question… How do you control movie playback on your Sony Playstation 3? This complete guide has all the answers:

Sweep-Away Cabinet Vac by Galaxie

The Sweep-Away is a self-contained vacuum cleaner that functions both as an automatic dustpan and powerful central vacuum. It stows away neatly inside a standard kitchen or bathroom cabinet and plugs into a standard wall outlet. The home I installed this in was built in the 1960's and is 1600 square feet; all flooring in the home is hardwood or tile. The house was built prior to central vacuum systems so this cabinet vacuum is an affordable and effective alternative.

The First Watt B1 Buffer Preamp

So here we are in the New Millennium, and thanks to Tom Holman and THX we've got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more. Think of it this way: If you are running your volume control down around 9 o'clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up. Routinely DIYers opt to make themselves a "passive preamp" - just an input selector and a volume control. What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors - just musical perfection. And yet there are guys out there who don't care for the result. "It sucks the life out of the music", is a commonly heard refrain (really - I'm being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp. I suppose if I had to floor the accelerator to drive 55 mph, maybe I'd think the life was being sucked out of my driving. Then again, maybe I like 55. Nice and safe, good gas mileage…

The Freedom of Wireless USB Technology

With the overwhelming success of USB technology as the preferred interface, comes the challenge of organizing all of the cabling from desktop peripherals. Users with multiple USB peripherals find the clutter of cables unsightly and inconvenient to their workspace. With many different USB connections for mobile devices, such as cellphones, cameras, MP3 players and PDAs, it becomes increasingly difficult to use them on the go. To overcome these challenges a new method for connecting peripherals has come to fruition. A method, which offers the same benefits of a physical USB connection without the need for unsightly cables, a technology known as certified wireless USB. Using an ultra-wideband radio frequency ranging from 3.1 - 10.6 GHz, 127 devices can connect to a single computer up to 10 meters away without a hub. Connections made less than 3 meters away from the host can benefit from speeds typically USB 2.0, while connections from 3 to 10 meters will operate at 110 Mbps. Devices that support dual role or direct connections with each other can also operate with wireless USB technology.

The Rebirth of 3-D - Part I: 3-D Is Born

There has probably been no cinematic special effect that has the longevity that the process of three-dimensional filmmaking has. From the B-movies of the 1950's right up to the state of the art big-budget blockbusters being presented in 3-D on cinema screens today, the effect of 3-D has held a tremendous grip on moviegoers since its very inception and the allure of this tantalizing effect has on the eyes and the mind have kept moviegoers enraptured and hungry for more. In order to fully understand how movies in three-dimension became popular in the first place we must go back to America circa the 1950's. With the advent of television after the Second World War, many moviegoers opted to stay home and watch their television sets instead of going out to the cinema. Filmmakers needed a gimmick… something that would make the movie going experience unique and the gimmick would have to be something that could not be replicated on television sets. Thus, the concept of three-dimensional entertainment was born. When the 3-D format was first introduced on the American cinematic scene, the format could only be replicated in movie theaters and in order to view the film in the three-dimensional format, a movie goer would need a special pair of glasses and keep the glasses on while the movie was shown.

TV - Q&A

What is the difference between 1080p and 1080i displays? The difference is how the source conveys the information to the display. Interlaced: 1080i sources get transferred on the screen sequentially. The odd-numbered lines of resolution appear on your screen first, followed by the even-numbered lines all within 1/30 of a second. Progressive: 1080p sources get transferred with all lines of resolution simultaneously, which makes for a smoother, cleaner image, especially with sports and other motion-intensive content. The right technology for you is dependant on the content you watch. The majority of HD content via satellite and cable will be available in 720p & 1080i. Your Blu-ray or HD DVDs will be available in 1080p with the appropriate player.

Wall Of Sound

We at McIntosh Labs were pretty impressed with ourselves when we realized the McIntosh 2K reference system weighed in at close to one full ton. It never even occurred to us to imagine what kind of McIntosh system might weigh 75 tons. As it turns out, our imagination was not required. Nearly 32 years earlier, Owsley 'Bear' Stanley, Dan Healy and Mark Raizene of the Grateful Dead sound crew and Ron Wickersham and Rick Turner of Alembic Sound dared to dream of such a system.

What the heck is a Smart Grid?

Nowadays we have several issues to face that are causing concern to humanity in general and the western world specifically. I don't think I need to repeat them here but basically they are environmental as well as geopolitical in nature. Hence, the old coal or oil burning power plant needs to be phased out and we must become much more efficient at generating and delivering electricity to end users or the costs become extraordinary over time.

A "Cedia" Low-Voltage Initiative Proposal

Somewhere in the mid 1980's, the NAHB Research Center in Washington was run by a guy I knew (whose name I can't seem to dig up) who had a wacky vision. His idea was to reinvent the way electrical power was distributed throughout the home. They called it Smart Home (not to be confused with the Disney movie of the same name or other stuff that uses that name now). I think it was the first use of the name.

Adoption of Wireless and Powerline Controls

One must consider all of these factors in determining whether electronic controls will replace electromechanical toggle switches. Wireless and powerline controls effectively address two factors in a positive way: absolute price and infrastructure. First, the cost of products based on these technologies is significantly less than traditional control systems installed by home systems integrators. Second, the infrastructure is already in place, so no new wires are needed.

Audio, Distortion and Feedback

Feedback is very large subject, and I am going to limit myself to some simple tutorial comments and a discussion of phenomena associated with complexity in distortion created by nonlinear gain stages, negative feedback, and the audio signal. Taken singly, these phenomena seem simple enough, but when they interact, they create distortions out of proportion to what you expect from the specifications found in product brochures. There are linear and non-linear forms of distortion. Linear distortions affect the amplitude and phase of audio signals, but don't show up on harmonic distortion analyzers as added frequency components that weren't there in the first place. Tone controls are a good example of circuits with linear distortion. Nonlinear distortions are those which add new frequency components to the original signal, either as harmonic multiples of the original frequencies or as sidebands resulting from their non-linear interaction between the original frequencies. Nonlinearities are often deliberately created in musical instruments themselves, but they are unwanted in music reproduction. We will be talking about nonlinear distortions.
