Especially musicians, guitarist would work very preanf’s circuits and printed circuit board designs are quality tested.
Stereo Microphone Input with Equalizer Circuit Preamplifier
Preamf circuit design of very high quality two channel audio stereo input / output and microphone input, and volume control are also bölümleride ekolaz there. TL072 opamp tl071 and provided with the check of the circuit supply voltage provided by a 9-volt 300mA transformer
Normally a very opamp works with symmetrical supply symmetrical voltage transformer in this application were obtained from a single so file must use the power supply circuit or do you do a standard symmetrical supply circuit.
Tl074 opamp circuit built on a 3-band equalizer and jrc4558 distirisyo volume control and selector switches are finding the effects section. operating voltage of 12 volts DC 2 × 2 × 9 volt ac to karnagama symmetric power transformer 300mA proposed
