Audio Surround Decoder Circuit

The circuit schematic drawings Surround Audio Decoder and its components and how to make it ,Audio surround decoder circuit. Surround sound quality is the process of adding the audio source by increasing the number of speakers. This is done by producing audio multitracking in a way that can be issued on a multichannel speaker.

Basically surround adopt an existing stereo system. The system uses a two-speaker stereo is right speaker and left speaker. With two speakers will be three-dimensional effect of the sound issued. With the surround, which generated three-dimensional effect was more extensive than in stereo. This is because the surround speakers that use more than two pieces. In addition to supporting the three-dimensional effects, stereo field theory is also noteworthy to organize the arrangement of sounds based on the type of sound produced.

Component List :

Surround effects can only be listened to speakers who have more than two channels. Surround is a technique commonly used in todays films that utilize multichannel speakers. Surround allows voice can move from side to side, is a moving side to side is to move from one speaker to another speaker. To create three-dimensional sound effects you can use a series of audio surround decoder.

DIY Surround Sound

The debate of whether or not to install your own surround sound system has fallen on deaf ears and you have decided to tackle this delicate task for yourself. Good for you. The thing is you arent really too certain about where to actually begin this delicate procedure. At this point, Im assuming that you have purchased either a home theater kit or surround sound system for your home and are preparing to begin the actual installation process. A good place to start is by reading the instructions and owners manual that most likely came with either the kit you purchased or each of the individual components.

The thing to remember with a surround sound system is that nothing will work without the speakers and they will only work for their intended purpose if they are positioned properly. However, you need to make sure that the other components are in place before beginning to work with the speakers. I recommend, particularly if this is your first system that you go with a simple AV receiver, if youve already purchased a tuner, amplifier, and all that other great stuff it is no problem, just a little more involved as far as processes go. The installation of each of these devices is often as simple as finding a space for them and plugging everything into the proper slot. The good news is that most systems have the slots well labeled for just this purpose.

Once you have the receiver hooked up you should begin placing speakers. If you went with the basic 5.1 channel surround sound system you should have 6 speakers including the subwoofer. This is a good system to begin with and (if you purchased your AV receiver wisely) will leave room for growth and expansion in the future. I will begin with instructions for the placement of the 6 speakers for a 5.1 channel system and expand those instructions to include the others later.

With a basic 5.1 channel surround sound system you will have five speakers and one subwoofer. The placement of the speaker is important when it comes to placing the ambient sounds that are found in movies in the proper location in relation to the action onscreen. Three of the five speakers belong in the front. One speaker in the center and one each on the front left and right-the two remaining speakers belong behind you to the left and right (one left rear; one right rear). While this isnt an overly complicated concept youd be amazed at the number of people who have their surround sound systems improperly set up.

With the 6.1 channel system you will move the rear left and right speakers to the side and place one speaker to the rear and in the center. If you then upgrade from a 6.1 to a 7.1 channel surround sound system you will move the speaker that is in the rear to either the left of the right and install the additional speaker on the opposite side and to the rear.

If you are going to make the investment in a home theater or surround sound system please take the time to insure that the pieces and parts are properly located and installed in order to get your moneys worth out of the process. Now its time to sit back and enjoy your new sound system.

5 1 surround amplifier circuit schematic

This 5.1 surround amplifier circuit schematic use the IC AN7168 as the main component from this circuit . Minimum voltage required 12V and maximum voltage 24V , I recomended it 12 V because the voltage support on are components. But if you want to better a loud sound you can raise it.

Maximum power output 40W with impedance 4 ohm . This 5.1 surround amplifier circuit schematic also support to make surround sound or 5.1 speaker. Use this amplifier on rear speaker , left right , and center but dont use to subwoofer speaker. See 5.1 surround amplifier circuit schematic below :

If you want to make a 5.1 surround sound you must make 5 the circuit of 5.1 surround amplifier circuit schematic , for left and right speaker , rear left and right speaker , and center speaker. Use the subwoofer speaker with support amlplifier subwoofer circuit .
