Box Kit Home Theaters | We live in a world where convenience is increasingly growing in demand. For this reason many home theater buyers expect convenience when it comes to the purchase and set up of their home theater systems. It goes without saying that there are all kinds of consumers in the world and even in matters of convenience supply and demand have not emerged to create a one size fits all society. We all want similar things in many ways yet we still want autonomy and selections from which to choose. The demands of a society that likes the ease of buying prepackaged goods have reached such a point however that packages are common place in everything from prepackaged dinners to prepackaged home theater systems. On one level these types of prepackaged theater systems provide a great deal of convenience to consumers. Among those benefits is the ability to know the cost of the entire system up front. This is actually a small benefit when compared to some of the other benefits...

Many people never bother looking into purchasing a home theater through sheer fear of the decisions that may need to be made in the process. Many among these aren’t even sure of exactly which components are included in a home theater or which ones are needed in order to create an effective and entertaining home theater. For this reason, many people simply do not bother going through the process of looking at their options when it comes to these wonderful systems on the market today much less ever bother actually purchasing one. Basic Components for a Home Theater If you are one of the many who has experienced some degree of confusion when it comes to the individual parts and pieces that are included in a home theater system and what they do, hopefully you will gain a better understanding once you’ve finished reading. The first thing to understand is that there are varying degrees when it comes to home theaters. The following components are the makings of a very basic home theater that...

Installation - This for many is probably the biggest reason to go with the prepackaged kit rather than a huge system of individual component—ease of installation. Most, if not all, of the prepackaged kits are very simple to install, which eliminates the need for professional installation and takes a great deal of hassle out of the installation process. Home Theater Installation The prepackaged systems are not however, the type of systems you will want to purchase if you intend to build a better system over time as they are not easily upgradeable and most true enthusiasts are often disappointed with the quality of the speakers and sounds that come with these systems. However if you have limited space and limited funds, these systems are often a great place to start when it comes to a home theater. You can always pass it on to your children if you decide to upgrade later.

This is a one watt home stereo amplifier module project using the KA2209 IC from Samsung, which is equivalent to the TDA2822. It operates from 3-12V DC & will work from a battery since the dormant current drain is low. It requires no heat sink for normal use. The input & output are both ground referenced. Maximum output will be obtained with a 12V power supply & 8 ohm speaker, however it is suitable for driving headphones from a supply as low as 3V. The Specifications of the home stereo amplifier : D.C. input : 3 – 12 V at 200 – 500 mA max Idle current : approx. 10 mA Power output : > 1 Watt max. 4-8 ohms, 12V DC Freq. Resp. : approx. 40 Hz to 200 kHz, 8 ohm, G=10 THD : < 1 % @ 750 mW, 4-8 ohm, 12V Gain : approx. x10 (20 dB) OR x100 (40dB) S/N ratio : > 80 dB, G = 20 dB Sensitivity : < 300 mV, G = 20 dB Input Impedance : approx. 10 k ohm Description   The gain is adjustable from ten to 100, i.e. twenty to 40 dB. Start with feedback resistors R1 and R3 of 1k...
