Power Amplifier

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 : Click to view large 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 .

Circuit combination of the 3 IC TDA2822  above can be used for 5.1 audio power amplifier system with low power output . The input signal used is analog signal not digital (SPDIF) , so it needed some input to the jack input. The speakers are suitable for use have impedance 8 Ohms , and with power 4 Watt, to Left , Right , Rear pair , center , and subwoofer speakers. To run this circuit , is also required circuit for volume control as tone control .

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.

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 aren't really too certain about where to actually begin this delicate procedure. At this point, I'm 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...

Power Amplifier LM3886  Audio Power Amplifier is an important part in the reproduction of sound in a sound system. Audio Power Amplifier LM 3886 with power IC Audio Power Amplifier is a highly capable and able to produce 68 Watts with power rata2 4Ohm load and capable of producing power 38 Watt with 8Ohm load.  With good sound reproduction capabilities of 20Hz-20kHz is also included on this LM3886 Audio Power Amplifier.
