Pre Tone Control high quality with transistor low noise

Designing power amplifier Circuit is high quality. The some is the thing that must think over most. Be Pre tone control circuit , but friends must not worry. I has this circuit that it transistor all work in feeding character gets back to model specialty. Be use Constant Current source be something bias that get from LED help have the stability in manner temperature work of Q1 and Q2 improve. The input can take a signal has since 100mV-1V don’t fear about Over Load , and the crazy low very. For other equipment can choose use general equipment. By sound quality still use well yes.

Stereo Preamplifier with adjustment tone by TCA5550

Many times we needed to use a simple circuit of preamplifier, with few components and facility of made. This circuit use a opamp. the Motorola, TCA5550, that contains a double amplifier, as outputs for the adjust of volume, balance, treble and bass. These adjustment of all parameters become from a line monophonic linear potesometers, increasing by far the facility of manufacture. The placement these potesometers should become as much as possible, more near in IC1, so that is minimised the noise. The circuit does not require big current in order to it work.

Tone – Volume – Balance with Electronic Control by LM1036

For simplicity, I’ve used the LM1036 tone/volume/balance chip to do this part of the mixer. The circuit is straight out of the LM1036 datasheet. In my mixer, I disabled the balance input by using a pair of fixed resistors to give it a DC voltage of VCC/2 Using the LM1036 may seem like laziness or a cop-out, but there’s a good reason for using it: it’s very difficult to get ganged pots, especially with a good match between channels. With the LM1036, you don’t need ganged pots. The disadvantage is a reduction in SNR, and having to use capacitor coupling in an otherwise straight-DC circuit. The capacitor coupling causes the loudspeakers to thump at switch-on. This is eliminated using the loudspeaker protection circuit.
