HDTV converters are specially designed devices for signal conversion. HDTV, also known as High Definition Television, is the most recent innovation in DTV. The HDTV can telecast pictures with high resolutions which are twice more than the traditional analog telecasts and surround sound.

Generally, the HDTV converters are incorporated in most of the HDTV systems. But, the HDTV systems are quite expensive. Moreover, today, most of the homes have analog television sets. To enjoy the effect of HDTV, you can implement a HDTV converter in your analog televisions sets. The HDTV converters will transform the digital signals into analog signals. Thus, the converter will help the analog televisions provide the maximum picture quality almost similar to HDTV sets.

To experience, the full benefits of HDTV signals, HDTV systems are always apt because the analog televisions will not be able to display the pictures with high resolution and surround sound as sharp as HDTV sets.

The HDTV converter automatically detects the input signal, which can be in RGBHV, YPbPr, or YCbCr format, and converts the signal into display with 480i, 480p, 720p, or 1080i resolution. Apart from this, the HDTV converters can also take 480i component video signals, and decode into the display with HDTV resolutions, where, "i" means interlaced and "p" means progressive. HDTV converters can transfer numerous pixels on a scan line into analog signals for horizontal resolutions. In the case of vertical resolutions, the HDTV converters will transform the 16:9 ratio HDTV picture with 1080i into a 480 scan line picture with 4:3 ratio or a picture with 360 scan line with 60 line black letterbox bars.

Unlike the ordinary television converters, HDTV converters are highly compact devices embedded with cutting-edge technology. With the increase in the demand, different brands and types of HDTV converters are available in the market. Philips, Viewsonic, Doremi Labs, Inc., JVC Professional Products Company, and Panasonic are some of the leading brands in HDTV converters. Prices of the HDTV converters will range from 0 to 0. HDTV converters can be purchased from local outlets or electronic stores. For better option in prices, brands, and types, online or electronic stores are always ideal.

Adding A Subwoofer Will Make Your Sound System Better

!9#: Adding A Subwoofer Will Make Your Sound System Better

No matter what kind of music you like, or how softly or loudly you like to listen, subwoofers are a crucial part of your overall listening experience. Subwoofers are used to give your system depth and deliver complete sound. Subwoofers are designed to reproduce only the lowest frequencies in the music or movie sound track. The intention in a system with a subwoofer is often to use small satellite speakers (two for stereo and five or more for surround sound or movie tracks) and to locate it in a hidden location. Typically, subwoofers for a car installation are installed in the trunk or back seat space.

Types of Subwoofers

The two types of subwoofers are passive subwoofers and active subwoofers. The easiest way to visually distinguish a Passive Subwoofer from a Powered Subwoofer is to remember that only a Powered Subwoofer plugs into a wall. Subwoofers are available in several formats, including bass reflex, acoustic suspension, infinite baffle, and bandpass types. Subwoofers use drivers (woofers) typically between 8" and 15" in diameter, but some have been as large as 60". Subwoofers can be purchased in their basic form, which is unmounted and not yet ready to be used, or can be purchased already installed in a box. Therefore, subwoofers are useful for supplementing main loudspeakers by providing playback of low bass frequencies at high levels.

Complete Audio System

A subwoofer can make the difference between a good-sounding and a great-sounding system. Once you've got an idea of what type of subwoofer or system you'd like to buy, comparing specs can be helpful in making your decision. Particularly among low cost systems, however, inclusion of a subwoofer may be little more than a marketing device. If mini-speakers are used as surrounds in Dolby Digital or DTS systems, an inexpensive passive or powered subwoofer can be added to the rear for maximum performance. A passive sub can add bass to any system and can be connected to any stereo or surround sound system.

Powered Subs

A powered sub combines an amplifier and woofer in an enclosure. Like the passive subs, they may not be the best choice if you're looking for really big bass, but they'll more than suffice for most listening needs without taking up a lot of interior space. Make sure you match the sub's power handling to your amp's power output. A powered subwoofer's best placement is in the front of the listening area in one corner of the room. Powered subwoofers are recommended in Dolby Digital/DTS systems if you wish to hear the full effects of Dolby Digital and DTS. Most importantly, true, deep powerful bass is critical to realistic home cinema sound.

If you're starting from the ground up in designing your custom system, choosing the subwoofer is a great place to start. A subwoofer is a speaker that is designed to reproduce very low bass frequencies (usually those between 20 Hz and 125 Hz). Even normal consumer-grade subwoofers are often capable of generating exceptionally high levels in home theaters or cars. There are many models to choose from and many price ranges to fit any budget.
