TDA7297 DIY Stereo Power Amplifier

TDA7297 Power Amplifier circuit

This is a series of stereo power amplifiers that use TDA7297 chip amp, this chip amp sounds less familiar maybe because of the power that is not so great. The power released by this power amplifier is about 15W x2 (stereo), this power amp circuit is often used in TV or radio amplifiers. But no one, if you also try to come make this audio power amplifier project. 

I've tried this tda7297 chip without PCB and the result is pretty good for mid sounds sounding flat and clear. By using a 12V power supply and I used to overload the speaker 3.5 "x 2 speakers with 60W power. Here is the circuit I am trying to chip amp TDA7297:

500W-2000W Power Amplifier SOCL 504

Power Amplifier SOCL 504 500W-2000W
The SOCL 504 Power Amplifier circuit is now possible again as the trend amplifier, is simple and the quality is good for indoor and outdoor sound and cheap power amplifier circuit. Well, turn your trying to listen to how the 500-Watt SOCL that in fact, the result of the development of 150 Watt OCL modified for high voltage above 40VDC.

Power Amplifier SOCL 504 500 Watt has tested with 45V DC and 80V DC voltage is still good and flat sound almost all the frequency obtained and still possible in the modification to tef to get bass thicker and an addition of the number of final transistors to increase the power of 18-inch speakers.

Three transistors are VAS deliberately bolted on the PCB board though not hot, just the model let it be different from the original version. To get the maximum output power the power amplifier circuit requires a DC voltage source with a large current so that the power supply for this power amplifier circuit should use minimal transformer 20 A can be given at least 45V DC to 80V DC.

DIY 2000W High Power Amplifier 2SC5200 2SA1943

Power Amplifier circuit 2000W
Here I will share posts about power amplifier with high power that can generate power up to 2000Watt or 2kW. Also, before I publish a power amplifier with high power that is almost same with 1600W High Power Amplifier. The same power amplifier using the final transistor with 2SC5200 and 2SA1943 is good enough and powerful to drive 2 pieces of 18-inch 8 Ohm speakers. The difference is quite clear on the speaker protector, for power 2000W is not equipped with a speaker protector you can add it yourself to this circuit Audio Speaker Protector using IC555. And for the power supply is also wider ranging from 45Volt to 75Volt DC Symmetrical. This power amplifier is stereo 1000W x 2 but its bridge tie load (BTL) so the output power have 2000W RMS.

DIY 5.1 Home Theater with Gainclone Power Amplifier

DIY Home Theater Amplifier
Hello, after a few busy days with making a 5.1-channel home theater project using a Ggainclone power amplifier, this finally comes with very satisfying results. It is undoubtedly the performance of the Gainclone amplifier, in this project I use LM1875 IC and also LM3886. The number of IC that I use 5 pieces LM1875 and also 2 pieces LM3886. 

Where is the LM1875 IC for controlling Front speakers, Rear, and Center. IC LM3886 I use to control speaker subwoofer. Some components for making this home theater project is not small as well. There are several amplifier supporting components such as stereo and mono tone control, subwoofer module, and also USB soundcard to separating the sound output from laptop/ pc into 6 channel: Front Left, Front Right, Rear Left, Rear Right, Bass / Subwoofer and Center.

First I do the power amplifier assembly LM3886 and LM1875 I have prepared all the necessary components, for the circuit scheme you can visit this page: 

Assembling Gainclone Amplifier
Some components are ready to be assembled, for the more complete gainclone amplifier can visit the link above. IC LM1875 and also IC LM3886 you can buy at www.utsource.net and also other components you can buy the site at a relatively cheap price and good service. I myself bought IC Gainclone in utsource, very safe and comfortable buy there and do not hesitate to buy it I guarantee original.
Buy Parts from utsource.net

You can visit this link to buy IC:
To buy it please you can register first at utsource.net if you feel confusion you can ask the customer service is very friendly.

Wiring Circuit 5.1 Home Theater Gainclone Amplifier
Subwoofer LM3886 for home theater
After a good soldering and tested power amplifier. I have set up tone control, subwoofer filter, and also power supply. The power supply I use the switching mode power supply instead of using a conventional transformer.

To Assemble a tone control you can visit this link: Stereo tone control TL084 & Mono Tone Control 4558
Assemble the subwoofer filter you can visit this link: Subwoofer Module 4558
And also the power supply you can visit this link: DIY SMPS 10A 20-50VDC CT

 USB Soundcard/ Decoder 5.1 Channel

This 5.1 channel decoder is necessary to generate 6 different channel signals, for this home theater amplifier input I take from USB soundcard that I bought from the online store at a relatively affordable price. But the weaknesses can only be able to play music from a PC or Laptop because he is like a soundcard. For the installation directly plug this USB soundcard into a laptop and install the driver to a PC or laptop, then install the application as shown below.
USB Soundcard 5,1 Home theater
Just choose the picture with number 6 speakers, to make output 6 channel and connect the output to each input amplifier.
