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.

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.

5 Channels 2 Octave Graphic Equaliser by 4558

This circuit 5 Channels 2 Octave Graphic Equaliser,easy to make equalizer,
because using IC 4558 or 1458 or LF353 (nice)
If you are seeking Graphic Equaliser Circuit at can fine decorate the sound of music has full frequency sound section. As a result try out group this circuit before. May don’t be defeated.
Cut at frequencies of 50Hz, 200HZ,800Hz,3.2kHz and 12kHz.
Supply voltage may be anything from -15V GND -15V for IC 4558.
Besides I still lead model PCB try build can be usable easy increasingly sir.
