A Brief Look at White Bookshelf Speakers

Published by ShreveportDesigner under Audio Video

White bookshelf speakers could be the perfect addition to any living room. While many people have either black or brown speakers, white speakers make are an attractively different way to both decorate your shelves and listen to your music.


Let us take a look at a couple of white bookshelf speakers available at the moment.


Q Acoustics 2010 Bookshelf Speakers in White Gloss


These extremely compact speakers are speakers in a class of their own. They have top class distortion levels, and are ideal for either home cinema use or hi-fi music. They work well with the 2000C centre speaker and 2070 subwoofer.


Product Specifications:


Bass Unit: 100mmEnclosure type: 2-way reflexFrequency Range: 68Hz – 22kHzTreble Unit: 25mmWeight: 3.5kgNominal Impedance: 6OSensitivity: 86dBRecommended Power: 15 – 75wMinimum Impedance: 4OCrossover Frequency: 2.8kHzDimensions H/D/W mm: 234.5 x 203 x 150


Cabasse Alcyone-W Satellite Wall / Bookshelf Mounted Speaker (White)


When you first look at this speak, the first thing that strikes me is how totally different it looks from the other set of speakers I just mentioned above. Whereas the other speakers were more of a standard speaker shape, this speaker has a look all of its own. It looks like something from the future, with its round satellite style appearance.


Product Specifications:


Style: Satellite SpeakerAppearance: Glossy whiteDrivers: 1 x 8 cm (3.2″), Wide band ICF driverSuggested Use: Bookshelf / Wall / StandEfficiency 1 W/1 m: 91 dBFrequency Range: 250 – 18,000 HzNominal impedance: 8 ohmsMinimum impedance: 4 ohmsMagnetic ShieldingPower handing / Peak power: 50 / 350 WDimensions: 9.9 cm / 3.9″ DiameterSpeaker Weight: 0.7 kg / 1.5 lbs


So there you have it, two very different white speakers. Obviously there are far more white speakers than this, many of which would be ideal for placing on your bookshelf to listen to music or home cinema. However, this at least gives you an idea of the kind of products that are available, so you can start to make an informed choice.

Projector Mounts

Published by ShreveportDesigner under Audio Video

You can run your projector from any handy table. Some people use a roll-around cart that as a mount for their projectors and for nothing else. You’ve probably been to presentations where the speaker was using a projector and it took almost as long to get the projector situated so the picture could be seen as it did for the speech itself. I usually don’t trust the speaker very much if he/she is no better prepared than that.


Actually, most manufacturers of projectors also make projector mounts although some companies that don’t make projectors also make good projector mounts. If your projector is always used in the same room, a permanent or semi-permanent mount makes life easier. You’ll find that in most boardrooms the projector is permanently mounted. Also, auditoriums where a projector is used frequently will have permanent mounts for their projectors.


Types of Projector Mounts


Ceiling Projector Mounts. These mounts are often used in home theaters and auditoriums. They are usually easy to install as long as there is an anchor in the ceiling. These mounts are sturdy and made to bear a lot of weight. Mounting a projector on the ceiling keeps the projector away from being bumped causing the alignment to become inaccurate. Also, being anchored into the ceiling, the projector is less likely to be stolen.


Wall Mounts. These are easier to install than ceiling mounts, and they have a larger range of height adjustment. Some ceiling mounts can be used as wall mounts based on the mounts pivot point. This can be useful when the ceiling is too high for a ceiling mount. It’s also useful in a boardroom where presentations are frequently made and traffic is constant between the projector and the screen.


Price


Mounts come in a range of prices depending on where you will locate your projector and how complicated the mount, itself, is. For example, a ceiling projector must have long mounting attachments. However, you can find just about any kind of mount you need for under $150.00.


Where to Shop for a Projector Mount


Any store that carries projectors will also carry mounts. However, it’s a good idea to shop online at first to get a feel for costs and varieties. Even an online source usually has a help line, so you can obtain the kind of advice you need to purchase the right mount for your own home theater or your company’s boardroom.

Inflatable Projector Screens – 4 Rules to Follow When Buying Your Backyard Movie Screen

Published by ShreveportDesigner under Audio Video

Inflatable projector screens can be just right for your backyard movie screen. There are many different brands, and models from cheap no-name screens to ultra-high quality premium screens.


There are 4 rules that you absolutely should follow when purchasing an inflatable movie screen.


1. Make sure the screen can handle the conditions it will be exposed to. Not all screens can handle windy conditions, or wet conditions. You will want to make sure that the outdoor projection screen you buy explicitly states that it can stand up to the elements it may be exposed to. Special mounting hardware may need to be set up.


2. Be certain the screen can inflate quickly enough. You do not want to be sitting around waiting for hours while the screen inflates. Most inflatable projection screens inflate using special fans which are meant to rapidly send air in. These mechanisms are not created equal so if you are unsure of how long it could take read reviews or check around on forums.


3. A black light absorbent border around the projector screen material is essential for the best picture. Some screens either have no border and end the screen right on the edge or the black border is the same reflective material that makes up most of the inflatable display. Ideally it would be made out of fabric, this is the black outline you see when looking at expensive projection screens.


4. Make sure the ratio of the display is correct for your projector. The ideal ratio for an HD projector is 16:9 and for a normal definition projector is 4:3. If you choose the wrong ratio there will be unwanted white space around the projector image so be sure to check this before you buy a projector screen.

What Are The Cautionary Steps To Take Before Installing Your TV On The Wall?

Published by ShreveportDesigner under Audio Video

After having had a hectic day outside, most families cuddle up together at dinner time and have an enjoyable TV viewing experience. However, with passage of time and introduction of technology, people now prefer to save floor space- which means that the television with all its accessories needs to go up the wall.


With previous heavy TV sets this idea seemed impossible but with the new plasma, LCD or LED TV’s- this imagination has come true. You can now actually have TV sets installed on the wall, save a lot of space and yet have an excellent viewing experience! Nevertheless, nothing comes in handy. A lot of cautions must be undertaken before you install your TV on the wall. The major precautions to be observed have been mentioned below-


* Firstly, it is always considered better to either hire a professional to do the mounting job or go strictly by the installation guidebook. It is only the expert opinion provided here which must be thoroughly read, observed and practiced.


* Purchase a wall mount kit. Not only would this guide you through the entire process but not being able to follow this kit could result in serious damage caused to your TV and other equipment.


* Do not place the TV in direct sunlight or near other electric outlets. This may cause a short circuit due to the intermixing of wires. Ensure that the electric points are at a safe distance from your television.


Precautions, as they say, are much better than cure. It is always preferable to exercise these before you mount your TV set on the wall.

Home Theatre Systems Have Four Major Components

Published by ShreveportDesigner under Audio Video

There are average home theatre systems and then there are spectacular home theatre systems. What makes the best isn’t necessarily the pricing, it’s more in the sights, sounds and atmosphere that’s created when an entire system is moved into a room and is fired up.

Finding the best in home theatre systems can be a tricky prospect. There’s so much to consider, it can make a person’s head spin. To make it a little more simplistic, there really are only four basic components to consider when choosing to put together a system. Each one, however, is very important. This isn’t to say that pricing needs to be outrageous either. There are some great systems that have been built using budget products. As long as the components are well chosen and installed correctly, a $1,000 system can seem like a $10,000 system to a homeowner.

The four major areas to spend time researching buys for a home theatre system are:

* Projector or television: Home theatre systems can involve projector screens or they can involve actual larger screen televisions. Both have their perks, but they should be chosen carefully. Things to consider here are pricing, room size, screen size and even personal tastes. Some people simply love the look of a projection screen, while others prefer the sleek appeal of a giant plasma screen television hanging on the wall. What’s right and what’s best depends on who is buying the equipment.

* Sound system: Don’t discount the importance of having surround sound to make a home theatre system really stand out. One of the biggest things that sets the movie theatre experience apart from watching television is the sounds. These can be achieved at home – even on a budget. Just look for the best set up within personal means and remember there should be multiple speakers and a control system for a true surround sound experience.

* Auxiliary devices: A projector and a surround system can be very lonely without a good DVD player, VCR or other movie-playing device. Whether you intend to pipe in movie downloads from a computer or you want to play your own DVDs on your new big screen, these devices are key in making a home theatre function properly. Fortunately, these devices offer very good options in just about every price range imaginable. A $40 DVD player can work extremely well when put in the mix with a higher priced television and surround sound system.

* Furniture: This might not seem like a major component for a home theatre system, but it is. A theatre room won’t get the use it’s intended for if people aren’t comfortable sitting in it. This is especially the case for planned movie marathons. The more comfortable and functional the furniture the better. Plus, the furniture can even be designed to really add to the atmosphere, as well.

There are a lot of things to consider when putting together a home theatre system. As long as the four major components are covered and covered well, a room should function to its owner’s expectations. Bringing the movie theatre experience home doesn’t have to cost an arm and a leg, but it does require some planning.

A Few Words About MP4 Players for the Average Consumer

Published by ShreveportDesigner under Audio Video

Just when you thought you were getting a handle on MP3 players and the sea of file formats that you might potentially need supported on any device you purchase, along comes MP4. What are MP4 players and why would you be interested in buying one? In reality an MP4 player, also often referred to as a portable media player, is basically a MP3 player with the added capability of playing MP4 files and using video format in addition to audio.

MP4 players allow users to store movies, TV shows, music videos, and photos along with songs. Some of these devices even have FM tuners, voice recorder functions, cameras, and built-in TV tuners. The ability to view e-books, play games, access the internet and record from TV are available on some models.

The pricing of an MP4 player varies widely; from under $100 to as much as $2,000. The functions and number of file formats supported however varies widely. It is important to know what audio and video formats you will most often wish to use and which the particular device you are considering will support.

Portable Media Centers are generally the most expensive types of MP4 players and are targeted for an audience with Media Center PCs. The major drawback to portable media center devices is that they don’t support DivX and XviD files.

Hard disk MP4 players offer many more features and are more popular due to this and their lower price tag. They offer a built in screen and support for WMA, MP3, DivX, and XviD files as well as others. For anyone searching for a smaller and more durable device, solid state/flash memory type MP4 players are a good choice as they have no moving parts. Files are stored in flash memory or RAM. Pricing for flash memory MP4 players tends to be higher than for the more common hard disk type players.

If cost is the primary consideration, CD/DVD players are probably a good choice. These devices offer large screens and the most reasonable pricing. They do tend to be more bulky however and can skip when jostled around.

When shopping for a MP4/portable media player, new users should put hands on several devices to determine the quality of both the video and audio playback. These features are core to a buyer’s satisfaction. Screen size, resolution, and brightness can vary significantly among brands. Some screens offer widescreen viewing and others have screens which reduce glare. When looking at audio quality, the headphones on the device should also be tried. In many instances, purchasing higher quality headphones is worth the purchase price.

Memory capacity of course is also a consideration as video files in particular take up a great deal of space. A half hour TV show for instance may take up 200 MB of space. In case additional storage will be needed in the future, buyers should determine what type of storage can be used and how much it will cost.

Certainly another important factor when making a purchase is to determine which features will be most desired. For instance, will the user want to see lyrics for songs displayed during playback, would they prefer to have HD or widescreen viewing capability, is the ability to connect to the internet important, or would they make use of their MP4 device for playing games? Shoppers should think through how they want to use an MP4 player before making their selection to avoid any disappointment after their purchase.

How to Compare LCD with Plasma TV

Published by ShreveportDesigner under Audio Video

When it comes to flat TVs, two technologies come to mind, LCD (Liquid Crystal Display) and Plasma. A lot of people are puzzled about these two types of flat screen technologies and choosing between them can be quite a bewildering task. If you need to compare LCD to Plasma TV, you may find something useful in the following information.

Flat Screen Technologies Compared

The LCD screen is comprised of two clear panels that have a crystal-filled liquid between them. These crystals reposition themselves to either block light or let light pass through and the result of millions of crystals doing this is the picture on the display. The action of the crystals is triggered by voltage.

Plasma TV, on the other hand, is composed of millions of small glass cells filled with rare gases such as xenon and neon. These cells are lit by phosphors that are activated by electrodes. Each cell contains three different colored phosphors – green, blue and red. Like in the LCD screen, the combination of the millions of cells forms the image on the display.

Picture Quality and Performance Compared

Brightness – according to independent viewers, LCD TVs are brighter than plasma TVs. On the average, plasma screens have brightness ratings of about 100 candelas per square meter while LCD TVs have around 450. This perception of this brightness is of course dependent on where the TV is located and what is being watched.

Contrast Ratio – contrast ratio measures the distance between the darkest and whitest display of the TV, a high ratio means greater details can be discerned. In the real world, LCD TVs reportedly have higher contrast ratios which can amount up to 450:1 compared to 200:1 for plasma TVs.

Color Saturation – color saturation measures the accuracy of the colors on screen based on the present of gray shades, higher gray shades results into lower saturation. Plasma TVs are famous for their high color saturation due to the method it emits light. The ability of Plasma pixels to be turned off when they are not in use prevents the emission of stray light that diffuses color. This is why tints and hues in Plasma TV are noticeably more vivid and vibrant.

Size – plasma TVs are generally larger than LCD TVs. Plasma TVs can be as big as 60 inches but can only be as small as 32 inches. LCD screens can be as small as 13 inches but no larger than 46 inches. Sizes beyond these ranges are being developed, however.

Viewing Angle – pictures in plasma TVs are still clearly discernible at about 160 degrees and even 180 degrees for some models. With LCD TVs however, the picture becomes dull beyond 100 degrees.

Lifespan – Plasma TVs can last for 20,000 to 30,000 hours which means that it could run for around 20 years with an average usage of 4 hours a day. LCD TVs last longer, with a lifespan reaching to 50,000 or even 60,000 hours, meaning it could last 40 years with an average daily usage of 4 hours.

Costs – since LCD TVs are generally smaller, they are also less expensive compared to Plasma TVs. LCD TVs also use less electricity

Flat screens are continuing to be the popular choice among televisions these days. Whether it is Plasma or LCD, a flat TV can definitely give you a more hip viewing pleasure.
