Usually people pake Sanken power amps because vocalnya thick. To increase
power, just add it Sanken transistors, and do not forget to use a transformer is
You can also use the scheme above for panel transistor (2N3055 and mj2955),
Sanken transistors replaced with a transistor panel. But remember, he started the
panel who MALAYSIA, pake voltage 32 volts.
The audio power amplifier is an important component part of the audio system, an audio signal to obtain a sufficient driving power through its enlarged after completion of the reproduction of the sound signal fed to the speaker. The stereo power amplifier as the core is based on the the Sanyo design of integrated circuit LA4445.
BTL or Stereo Audio power amplifiers KA2206, KA22061, LA4180, LA4182, LA4183, LA4550, LA4555, LA4558 Circuit Diagram
This LA4550 amplifier circuit is wired in bridge mode (BTL mode). For stereo application, two identical amplifier modes have to be built according to the circuit diagram. The LA4550 can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker.
Simple microphones pre-amp with automatic gain control. Automated gain control is a circuit design which preserve the same level of amplification for sound or radio frequency. Using single supply op-amp LM741 and low noise FET 2N3819, 2N3823, 2N5397.
The pre-amplifier is very easy to get on the board, and an innovative tone defeat. Instead of completely disabling the sound system, the massive de-sensitized, and they suggested a maximum range. This can be increased if you wish, you can have two tone controls, the elimination of 10 dB and a cut and the other with a little help and very subtle 3dB cut – it’s (surprisingly) a very small adjustment to the way For each day of the hearing.
The circuit shown in the figure, is base the LM1875 chip which has a soft, low distortion (0.015%) when the current is the style of the team is small enough, popular DIY chip amp. Power transistor control output with a more powerful sound warm and soft on the Toshiba power transistor 2SA1943, 2SC5200 (VCM = 180 V, 12 A = ICM, PCM ? 120W, fT = 30 MHz).
These single supply op-amp hi-fi stereo tone control preamplifier circuit with TDA1054 IC built by SGS. TDA1054 is a 16-pin DIL package and integrates two separate preamp.
It is a low noise preamplifier with little or no problem in the construction process. The first half of the circuit (IC1A) has an input sensitivity of 3 mV and has a frequency correction of the C5, C3, R6 and R8 together. The bass signal from phono input is amplified, while the high signal is attenuated.
Here is a simple circuit subwoofer filter that can be operated from a 12V DC. This circuit is very useful in automotive applications subwoofer. The circuit is a low-pass filter whose cutoff frequency can be set between 60-160 Hz subwoofer filter circuit with TL072 op-amp with a single 12-volt power.

Design set is made in a similar style, which will place the subwoofer, blending in with the speakers, even on the desktop. Speaker dimensions are relatively small and are 12 × 20 × 16 inches. The body is made of columns made of cardboard, wall thickness is 9 mm. You can use TDA2030 or LM1875 main chip power amplifier satellite and subwoofer. The pre-amp and low pass filter very popular op-amp TL072 or NE5532. You can replace with more low noise op-amp OPA series.
Amplifiers that operate from 12V DC, as a rule not put out much power, and they are usually not as good, hi-fi system. But this little stereo amp tics of power and low distortion boxes. With a 14.4-V power supply, it will deliver 20 watts per channel into 4 ohms at clipping, while harmonic distortion at lower levels of power in general, less than 0.03%.
This is an ideal project for those who want a compact stereo amplifier that can be operated from a 12V battery. It could be just the thing for an entertainer, the one you want small but gutsy amplifier that runs from a SLA battery or it could be used anywhere a 12V DC is available – cars, motor homes, remote homes with 12V DC or anywhere .
