A tri-amplifier has three in one a amplification act drive specifically each audio speakers makes the sound quality is very good. Normally amp can drive three speakers at the same time are the woofer, mid-range and tweeter. Which may have limits such as: the impedance of the speakers,the loss of signal in Crossover Network. But it’s very expensive. Thus when compared to the same quality and power. The price of the amplifier and crossover network, combination is more than the price of this the tri-amplifier. When viewing the various elements, then are seen as better in every aspect. Although there are not a lot of power. But it’s only for listening in your home or bedroom very well. The working principles The tri-amplifier will be has the separation a range of frequency of 3 ranges consist of a low frequency ( bass) , the medium frequency(midrange) and the high frequency [...]

This power amplifier series have disposition in circuit as OCL form is stereo system provide power driver of 14 watt / channel at load 4 ohm. Suitable for beginners thought will build the electroacoustics to listen yourself. This project use IC of The SGS company number TDA2030, which SGS said that TDA2030 is power amplifier IC in 5 pin form. Setting circuit on a class AB power amplifier to the output of the high harmonic distortion and low crossover, Ready, shock output protection, and the temperature is too high, complemented within the integrated circuit. As we experiment to build this project, and listen to the sound quality nice. We turn the volume fully to several hours. The IC is not hot. Or just warm. Therefore, suitable for beginners build this circuit to listen with yourself. Technical Specifications of IC-TDA2030 – maximum voltage supply used of +/- 18VDC. – Begin working [...]

Relatively easy to build up to 30 watt OTL amplifier is packed into this project. If you like to listen to music a comfortably ears. Want to create a your power amplifier projects with yourself. This project will direct your heart for sure. By the power dissipation of 20 watts at 8 ohm or 30 watts at load 4 ohm. And easily without any adjustments and Cheap because We use the three tiger army.. Read more …. The working principle. As shown figure the circuit, you know 3 soldier that from one IC-TDA2030 and two transistors (TIP41,TIP42 or 2SC1061,2SA761 or BD908,BD907) for helping to extend the signal up there. Part other equipment is useful Likewise. However will explain it to read as follows. When we enter the power supply and sound signals into this circuit. The capacitor C1 will prevent DC voltage through it. Therefore, the sound signals is at [...]

This The multi-purpose Amplifier using TDA2030. It is have power 8 watt (RMS) at 8 ohm loudspeakers. It is have low noise be valuable THD (Total harmonic distortion) 0.1% , When friends use Power supply Voltage Source 28 Volt at 4 ohm loudspeakers have output power 12Watt. But be high class the noise increases to are 2 times. Besides still three be usable with Volt supply about 9Volt , but there is the electric power is down respectively. The VR1 use for Volume popularity level of sound signal. By if a friend can’t seek 22K values use 50K values can replace. For other detail about the integrated circuit TDA2030 IC and other , friends see in the circuit better yes. ———————————– See pcb layout below —————————————– Power Amplifier Genneral Purpose by IC TDA2030 This is Power Amplifier Genneral Purpose circuit,main part is IC TDA2030. It is OTL Amp 10W rms [...]

This be Super Bridge 120W Power Amplifier by IC TDA2030 for you like the circuit amplifies that use the integrated circuit. and Transistor BD249 or TIP31 or TIP41 or C1061 and BD250 or TIP32 or TIP42 or A671. It is nice circuit and easy to use. circuit Power Amp Super Bridge 120W by IC TDA2030 PCB Power Amp Super Bridge 120W by IC TDA2030 This circuit is designed by using TDA2030A circuit as driver to power transistor output to applied to out up 30 watt. – then take both circuit to bridge together, makes we have the power output up to 4 times and have even maximum power output is 200Watt. May don’t be defeated because this circuit give the electric power about 120W that load 2 ohm. When see the circuit will think use important equipment be. Must use power supply source that be appropriate about +15V and -15V [...]
