   A professional suggestion for those interested in improving sound. The circuit constitutes the part of input mixing console sound from the microphone or source of high level . It can be used on it's own or be multiplied to the number of channels required. It includes all the useful functions such as, phantom power , reverse face, signal attenuation for avoiding distortions from high level signals regulating channel gains and the rest of the stages will be added next stages ,for full mixing console. Attention must be paid to the quality of the materials used. This circuit may used, previous to Parametric EQ circuit. Source http://users.otenet.gr/~athsam/mic_line_balance.htm

STK6153 production and use STK3048A amplifier, you reported to have introduced a lot, of which there are many improving circuit, but limited to the STK6153 performance, making the sets of combination play to the top circuit performance is not necessarily the broad masses of Shao You can meet the requirements. In this paper, STK3048A for voltage amplification, Coupled with ultra-dynamic bias circuit at the end of the production of a super-A amplifier. Power Amplifier Using STK3048A Circuit Schematic   Below the production elements and brief debugging. Transistor matching error should be 5 percent, the midpoint of migration can be controlled in less than 10 mV. Heat sink should try to get some large, to ensure the safety of power, the general weight of not less than 1,2 kg (two channels), if conditions allow the best and a small 12 V equipment Low Noise fans, for a mandatory cooling. Map k Ω resistance are blocked 0,5 W, Ω block resistance are 1 W, 0,22 Ω resistor is optional 5 W whi...
