Those who want to create themselves the speakers that are used to provide the sounds when you listen to music or when you watch movies on your computer or your TV can do this without too many problems, if they follow the instructions provided on a site that can be found on the Internet (obviously), site that is named: Crutchfield.com. This company is the North America’s electronics specialists since 1974. This is the phrase that appears below the name of the company, being a part of the logo, if I can say this. This is an A/V design group that allows you to enjoy music in your house, the way you want it.

If you want to offer some very unique speakers to one of your friends, you can simply buy the speakers and integrate them into a design created by yourself, colored by yourself and made of materials that only you can think of. You have to be sure that the sound to be able to get out from that assembly that you create.

If you want to enter the company’s site that I have just mentioned, you can find multiple solutions that will allow you to listen to music in every room. How can you do this? Well, if you read the introduction to want to multi-room systems, you will understand better what this means. You also need to understand how this systems can be powered and how you can create a wiring diagram, if you want to amaze the person that is going to receive your gift (colored in the way you want, having the design that you want and so on), you should use a wiring diagram, just like it is presented on the Crutchfield.com site, diagram that will help you and the final user of the product to listen to music or to sounds from many rooms at the same time. And the same time, when you will enter the site, you will learn more about how to install wall and ceiling speakers, how to create a wiring diagram directly on the spot, so not necessarily on the paper, you will be able to read the flat panel TV installation guide and how to combine the A/V systems with your furniture. You can use some universal remote controls if you want to stop the music from different rooms where you are able to listen to it, just make sure that you will use a single remote control, because if more people have access to more remote controls, they can change the music track that you listen, situations that can lead to fights between yourselves.

Simply by owning a remote control doesn't mean that you can use it with your multi-room system, this is why you need to learn something else: how to setup the remote control in order to be used with that multiroom system that you have created. So in order to create an A/V design for your home audio speakers, you need to take into consideration more aspects, not only the design of the product. Ok, the design may look nice, but the speakers must function properly, otherwise all of your work has been in vain.

Those who are interested in buying home theater systems created by Direct can simply enter the site named hometheaterdirect.com. They design and manufacture speakers and other types of electronics, that provide to you a great performance and a superb quality design. You can see how beautiful the HTD products are simply by looking at their pictures.

I will start with the main category names Products which contains information about: speakers, amplifiers, multi-room audio, cables/accessories, HTD outlet. This last subcategory would be interested to discover, but I will do this in another article. I'm pretty sure that the prices of the products that you can find in the outlet store of this company are definitely lower than the prices of the new products. Now let's move to the next tab, which is Expert Support, that contains the subcategories: it's personalized and it's free, upload your plans, audio guide/frequently asked questions, downloads, contact support.

The best A/V receivers are presented on the site named CNET.com. In order to feel the real home theater experience, no matter if you are at home or at the office, you will need an A/V receiver. For example, you can use the home theater system for web conference or for a local conference using an internal network. You need to hope for a 5.1 speaker system and a real A/V receiver; you can get used to a sound bar or to a HTIB, but a home theater enthusiast will want only the best. A usual receiver cost around $500 and for this price you will get around 6 HDMI inputs and built in networking functionality. I will start my presentation with Denon AVR-1912, which is an A/V network receiver, that amplifies the sounds using a power of 90 W and 8 Ohm. This one is the editor's choice on CNET.com, receiving almost 4 stars from those who have bought this product. Let's see the specifications of this product and in the next sentences we will present another option from CNET.

The sound is provided in surround, which means that no matter where you are standing or sitting from the speakers, you will be able to hear the same sound. If you have a musical equipment, a professional one, most likely you know what the surround sound means. There are some built-in decoders in case you want to use this A/V receiver with more types of speakers: for example, we have decoder for Dolby Digital Plus, for Dolby Digital EX, Dolby TrueHD, DTS Neo 6 and more. The audio D/A converter functions at 24 bits having a speed of 192 kHz. This device uses a digital sound processor, thing that doesn't really happens with all A/V receivers in this world. This was something that was worth mentioned, this is why the guys from CNET wanted to emphasize this.

The presets available on the DSP are referring to the sounds offered by a jazz club, rock arena, by a mono movie or by matrix (I don't really know what matrix means; this is the information provided by my source of inspiration). The surround system class is included in the 7.1 channel. The response bandwidth in of 10-100000 Hz. The maximum signal offered by this device before transforming itself into noise is of 100 dB. The input impedance is of 47 KOhm.

Now let's mention the other product that is available on the site, recommended by the editors of this article. They recommend the Pioneer VSX-1021-K A/V receiver, which is better seen by the customers, which have offered to it almost 5 stars out of 5. This one manages to amplifies the sounds using the power of 120 W and 8 Ohm. Just like the receiver that I have presented earlier, this one allows you to listen to the sounds in a surround way. The surround sound effect are: Headphone Surround and Front Stage Surround Advance. This product is not THX certified, but it uses an equalizer and a digital sound processor, also know as DSP. The surround system class is of 7.1.

I have searched on the Internet for digital audio paramaters to see what they are, because I want to explain this expression to all of you so that you will be able to understand me. I know what this means, only that this site is dedicated to everyone, not only to the persons that know technical terms.

And I have found that according to Wikipedia, one of the best known digital parameter is MP3. This is a standard and it is designed taking into consideration the Moving Picture Experts Group. In other words, MP3 comes from MPEG. It was derived from MPEG.

But MP3 is in fact a patented digital audio encoding format, not necessarily a digital audio parameter. It allows it to record, but also to play music tracks. This is the most common audio format known today. But what exactly happens when you play an MP3 song? There is a compression algorithm that is designed to read the actual data that is provided by the audio recording, by the disk, and to decompress it, make it ready to be listened by most listeners. You know that some of the people do not hear high sounds or low sounds, but these are their own problems. Right now we are talking about regular people. Let's take an example: the MP3 file formats are created using the 128 kb/s standard. If we think that the music files, when they are recorded on a CD, but not in the MP3 file format, are recorded having a size 11 times bigger, we realize the importance of MP3 in our lives. It means that we can store more information on a CD or a DVD if we transfer the music, as it is created in a music studio in MP3 files. The compression or decompression is done with the help of some powerful software music programs and the help of excellent engineers. Compression usually means that you cut some of the parts that are considered too high or below the auditory resolution ability of some of the people. This is, if I can say this, a method of audio programming. In fact, some of the engineers refer to it as being perceptual coding. The engineers use some psychoacoustic models in order to see if the sounds are too high or too low. Don't imagine that the engineers ask their friends to come to the studio and hear the sounds that they have created and recorded on CDs that record only MP3 files. They may do this as well, but not for the benefit of the majority of the people; plus, they must have a lot of friends in order to cover all the psychoacoustic models in this world. This is why it is better to use some software programs for this.

When you transfer the music as it is recorded in the studio on some audio devices, that do not do anything else but to render the audio sounds, such as the CDs and DVDs, you have to be very precise and to cut off the components that are less audible to the human hearing. At the same time, you need to pay attention to all the rest of the details.

If you look for information about the CD-R devices, the first result that will appear with be the Wikipedia site. On this site, you will find many explanations about the name of this hardware components, about the origin and about the history.

As I said in one of my previous articles CD-R means compact disc recordable. In other words this is a CD which can be recorded.

And when you say CD-R player it means that this is an optical drive or a disk drive, that allows the user to record using the CDs. I have for example a CD player in my computer and it is considered that I cannot run DVDs, but surprise, I can run DVDs, I can watch movies on DVDs and above all, I can even record DVDs. The CDs and DVDs allow you to record not only digital audio and digital sounds, but images and other types of documents as well. For example, you can store your financial information, you can store your graphics, your games, your iPhone applications that you develop and so on. Just make sure that you store the CD or the DVD in a safe location, so that no one else can find those information. The CD-R is a variation of a compact disc, as you can see on Wikipedia. This one was invented by Sony, as far as I know. On Wikipedia it is said that it was invented by Philips in collaboration with Sony. The CD-R device or hardware component is an item or product that can be written only once. Unlike many CDs or DVDs that are found today which can be recorded many times and that have the information stored on the information which is already saved by the CD or DVD, they allow the users to record them only once and to read them many times. In other words, you are able to record a movie and you're able to see it as many times as you want. Only that the CD with that film is going to be written a single time and not re-written. The discs that allow the user to re-rewrite them are called re-writable discs.

The discs that can be re-written and are usually more expensive than the discs that can be written only a single time. On Wikipedia, you can find more information about the history of the CD-R discs and players, about the physical characteristics of such a device, about the speed in which a CD is written and perhaps the difference between the speed of writing a CD and the speed of writing a DVD, about the writing methods, the expected lifespan, the security risks, the possibilities of recycling these items and many more. Nowadays, we don't usually use too many CDs or DVDs, because now we have the Blu-rays, which represent the highest level reached by the CDs or better said by the items that allow you to store information and which have the shape of a disk.
