Wireless Home Theater System

Published by Arlington Designer under Audio & Video

A home theater system can enhance your TV and movie watching experience by adding a great looking television set and surround sound audio. It can be great to watch alone, or used to impress all your friends that come over to watch the big game. It can even be your own at-home movie date. But many of these miniature living room theaters have the drawback of many unsightly cables running across the floor and along walls, making the area look overly cluttered. Recent technology has been able to fix this eyesore of a problem with the advent of the wireless home theater system.

Unfortunately, no wireless home theater system is completely 100% wireless. They do however severely cut back on the amount of wires needed, which is great for the look of the system and the room it’s put into for those that don’t have rooms that are pre-wired for speaker systems. Despite the name “wireless”, there are several connections that have to be made via wire and cables including attaching the transmitter box to your TV, often the front speakers need to be connected via wire to the transmitter, and the rear speakers will need to be plugged in for power as will the transmitter itself.

Often times these wireless home theater systems will have a signal that reaches no more than 100 feet. This is more than adequate if you’re just planning to keep your video and/or audio experience in one room. However, if you want to expand it into other rooms, you may need a more expensive system. You may want to look at a slightly pricier system instead of the cheaper base systems anyway. The phrase “you get what you pay for” really does ring true when it comes to wireless systems as the sound quality of cheap wireless speakers is nowhere near as good as the ones that come with all the wires. However, many of the pricier systems have sound quality that is good enough to become almost indistinguishable from the wired speakers.

Wireless home theater systems are much simpler to install than the wired counterpart. For starters, being nearly without cables, there are far less connections to have to figure out and pay attention to. Set up is fairly simplistic and straight forward and in many cases is just a matter of hooking up the transmitter to the television, plugging it in, and turning it on.

Virtual Surround Sound Systems – Big Sound Without Big Speakers

Published by Arlington Designer under Audio & Video

The newest must-have for anyone with a TV and stereo these days is a home theater setup. As usual for our got-to-have-the-best society, most people think big when they dream of their ideal home theater. How big? You know, big screen television, big sound from a powerful receiver and amplifier, and really big sound from the speakers spread all over the room.

But, once the dream dissolves into reality, many of us realize that this big setup just will not work in our homes. We might not have the room for all those speakers. After all, 5 speakers and a sub-woofer do take up a considerable amount of space. Or maybe, we just do not want all those cables running around the base boards. Or, we do not want the technical hassles of setting up and balancing such a large system.

Fortunately, those with limited space or minimalist design ideas still have options. The appeal of surround sound can be addressed in a different way. Technology has stepped in and developed what is being called virtual surround sound. Virtual surround sound has been developed to mimic the sound characteristics of a multi-speaker system. Even though it uses fewer speakers and cables, a virtual system approaches the overall sound of a 5.1 or 7.1 amplifier and speaker system. There are two primary varieties of virtual systems, the 2.1 surround system and the digital sound projection system.

The standard placement for the 2.1 speaker system is to place two speakers in front of the listener, along with a sub-woofer placed somewhere inconspicuously in the room. The system will recreate the effect of a larger 5.1 setup that has 5 speakers and the sub. On the other hand, digital sound projectors will use a single strip of relatively small speakers to produce the sound. Most often, the digital sound system will not have a sub-woofer.

In either case, even though the setup is different, the same basic principle exists. The technology behind the system is based on a knowledge of how humans process sound internally. There are certain techniques used to modify the sound waves to fool the human ear into thinking that there are more speakers than what really are present. These techniques come from studies of psycho-acoustics, or the study of the way that people perceive sound. To fully appreciate what technology has done, you need to understand a least a little about psycho-acoustics, as well as physical acoustics (the science of sound).

He has an extensive background in live sound applications for various size venues, as well as the recording studio. He believes that the best performance in the world can be ruined with just a second or two of bad sound reinforcement. The proof of a well-designed sound equipment speaker application is that it is not even noticed by the audience. Invisibility is the ultimate goal.

How much could be the cost for such installation? What difference will it make?

Total entertainment means getting entertained through all the five senses that the human being has. For common man the entertainment might mean many things like music, cinema, games etc. the choice of entertainment also depends upon the budget or the financial eligibility of the person involved. People who are filthy rich create their own entertainment arena by personalizing their needs. This is how home theatres came into being. Very rich and famous instead of seeing movies from regular theatres can now watch any movie in the comfort of their home with same audio and video quality.

Generally a home theatre design should consist of

• input devices
• output devices
• processing devices
• audio output
• video output
• atmosphere

The rates of these devices can be anywhere from few hundreds to thousands and even millions of dollars according to the spending capacity of the client. Specialized service personal like the fashion designers can design, process and install these home theatres according to the personal needs of their customers. From sound proof rooms, to designer interiors and music systems with shock proof equipments is any mans dream.

Choosing the right designer to meet personal design needs is what is imperative. Some might need residential home unit and others commercial unit. Whatever the need it is always important to test for the right quality and then decide after experiencing the sound and video effect. The budget also should be discussed before hand and any extra cost must be clarified. The installation time and the after effect must also be tested for accuracy. Different systems work differently as per the room size and the shape. So the home theatre designers must be knowledgeable about this and experienced too. If possible check out some of their customer whom they have served for getting a feedback about their services. It is good to search thoroughly for the right person for this great job.

How To Connect Your Digital Receiver To Your Home Theater Setup

Published by Arlington Designer under Audio & Video

In the not too distant past, stereo receivers were only used for connecting components of your home stereo system and switching between them, but times have changed drastically in the home entertainment field in just the last few years. Today a stereo receiver, or digital receiver as they are sometimes called, is expected to also handle video inputs from any number of devices and be able to route that as well to the TV set. In addition, today’s receivers must have the capability to decode surround sound and support up to at least 5 speakers and a subwoofer. That’s a lot to ask, and also a lot to connect up, so let’s discuss how to connect your digital receiver to your home theater setup.

If you buy an all-in-one home theater system package, you probably won’t have much problem setting things up because it’s all usually laid out for you in the instructions and the components should all match very well. But if you are putting together your own home theater package made up of different components then you need to plan ahead and buy the right equipment to get the job done.

As far as the receiver is concerned, be sure that you buy one that has the number of connections that you will need to handle all of your system components. For video, almost all receivers give you a connection for a DVD player, a VCR, and a cable or satellite box, but do you also plan to connect up a digital camcorder, a video game system, or digital video recorder? If so, you will need enough inputs for all these pieces of equipment too. And you can expect to pay more for that many extra connections, but if that is what you need, the cost is worth it.

Now you need to be sure that the connection types are what you want too. Almost all video equipment can be connected through a standard composite connection cable, but if you want to improve the video quality you will use an S-video connection instead. Having a good mix of input connections between the two can be a good idea as most camcorder video will not have to be of the highest quality anyway.

On the audio front, many digital receivers are coming with surround sound decoders built into the unit and that is usually the simplest solution. Just make sure that the digital connection for sound from your system components matches the input connection on the receiver. Usually it is either an optical or coaxial connection. Just be sure that whichever it is, they match on both ends.

Then be sure that you have enough speaker connections to drive your speaker setup. If you like to use the newer 6.1 or 7.1 surround sound system format you will need enough speaker connections on your receiver to power all those separate speakers.

Once you have the right equipment with the right connections, actually installing the receiver is a matter of staying organized as you go. It may be a good idea to label each cable set on both ends to remind you what goes where. And be sure to keep the polarity straight when you install the speakers too. Each speaker has a “+” and “-” terminal, so make sure that you match them up correctly with the corresponding terminal on the receiver or your sound quality will suffer.

Following a few well planned guidelines and being as organized as possible can help you to not only buy the right digital receiver equipment for your home theater setup, but also install it correctly as well.

What You Need To Know About Stereo Receivers

Published by Arlington Designer under Audio & Video

There has been a revolution taking place in the home entertainment and electronics field in the past decade that will change how we view and listen to entertainment forever. Not long ago, you watched TV and listened to stereo music separately. But increasingly audio and video sources have become combined and now we have a multitude of audio/video devices that we can choose to enjoy including dvd players, camcorders, video games, HDTV, and more. And with this audio/video consolidation the home stereo receiver has had to keep up with the times.

Today we have a wide selection of receivers to choose from. Of course, you can still get the most basic stereo receiver that accepts sound inputs and powers only two speakers at a time. In fact, you can get some very high quality equipment in this area very inexpensively now. In fact, you can build a very cheap and basic home theater setup by using the stereo receiver to process sound from a DVD player, VCR, and your TV.

If you get a receiver that has support for Dolby Pro Logic, Pro Logic II, and Pro Logic IIx, you can even get simulated surround sound from your home theater system if you have four or more speakers. Of course, the pro Logic formats are not digital, they are for analog sound inputs but it can help improve your sound quite a bit if you still use analog components.

For most modern uses though, you will need a receiver that can handle both digital audio and video inputs and then routes the signals to the correct component like your TV and speaker setup. On the video side look for receivers that have enough video inputs to support all the video devices that you plan to use, and also be sure that the connection types match up between the video devices you have and the receiver inputs. On the audio side, if you plan on using the digital surround sound capability that much of today’s entertainment is going to, your receiver should be able to decode both Dolby and DTS 5.1 surround sound and then support at least 5 speakers and a subwoofer to distribute each channel’s sound to the appropriate speaker.

You will want to have plenty of power to accomplish all of this and so for a typical home theater setup you will need about 50 watts of power for an average room, 75 watts per channel for a larger room, and for very large rooms 100 watts per channel or more will be needed to truly get the sound you want.

The top stereo receiver manufacturers are Sony, Panasonic, JVC, Onkyo, Denon, Pioneer, and Yamaha. If you browse their current offerings you will find that most of these companies make high quality products that will work well. The biggest question is what your needs are instead. Once you understand what your needs will be, you can then choose the best stereo receiver from any of those brands to fill those needs very well.

Features To look For When You Buy A DVD Player

Published by Arlington Designer under Audio & Video

It’s not hard to see why DVD players have taken the video world by storm. All you have to do is watch a movie on DVD and then watch that same movie on VHS tape instead. The difference can be startling. So just as CDs took over the audio world, DVDs are dominant in the video world, and DVD players are a staple of the home entertainment center, and certainly of a home theater setup too.

So what should you know when you shop for DVD players? Well, as with everything a lot depends on your budget but here are some of the features to look for when you buy a DVD player:

* In the electronics world, cable connections are very important and it’s no different with DVD players. Almost all DVD players come with a standard composite-video cable to connect the player to the TV, and this kind of cable can produce a decent picture. But it’s also very limiting because the black and white, and color video signals are all sent together through this cable and it’s easy for the colors to bleed over into other colors and lose detail and sharpness. If your DVD p[layer comes with a S-video cable this can dramatically improve the video as this cable can separate out the black and white from the color signals resulting in greater clarity. Finally if you get a DVD player that can use a component-video cable that can be the best yet because it also splits the color signal too, allowing even greater color range and detail.

* It’s good to have an aspect control feature on a DVD player too. Many DVD movies are coming now in different formats to fit whatever TV you have. The aspect control lets you take advantage of this and tune the movie to the specific ratio that best fits the size of your television screen.

* Some DVD players have multi-angle capability built in and that can be useful at times too. It doesn’t work with all DVDs, but with those that are compatible, it’s pretty cool. It actually allows you to adjust the picture angle so that you can view the action from different perspectives.

* Having surround sound decoding built into your DVD players can be very useful too, especially if you have a Dolby Digital receiver and at least six speakers to achieve the 5.1 surround sound effect. If your receiver does not have the Dolby 5.1 decoder built into it then you need to have it decoded by the DVD player before it is sent to the receiver. Once at the receiver the signal is amplified and distributed to the appropriate speakers in the room.
If you wish to use the more recent 6.1 and 7.1 surround sound systems you will need to have the decoder for that on your DVD player too, and either 7 or 8 speakers to match.

These are some of the features that can be most useful when you are playing DVDs, so look for them the next time you want to buy a DVD player.
