Low Noise Preamp Using Tlo71 System
Low noise microphone preamplifier circuit. This circuit can be used to all normal microphone, for example: the dynamic microphone of Europe zone that has impedance of about 200 ohms, the Japan microphone has impedance of about 500-600 ohms or others higher impedance microphone. This circuit have 2 model are a balance Input Pre Microphone Amplifier. 1byone High Gain Low Noise HDTV Antenna Amplifier Signal Booster for TV HDTV Antenna with USB Power Supply, Boost Any Non-amplified TV Antenna up to 15 Miles Range Gain 20dB Color White 3.1 out of 5 stars 172.
Here is two Low noise microphone preamplifier circuit. Which is simple circuit but high quality sound,includes devices that are selected very well.This circuit can be used to all normal microphone, for example: the dynamic microphone of Europe zone that has impedance of about 200 ohms, the Japan microphone has impedance of about 500-600 ohms or others higher impedance microphone.This circuit have 2 model are a balance Input Pre Microphone Amplifier circuit as Figure 1 and an Unbalance Input pre Microphone Amplifiers to can choose as you needed. Figure 1 Balance Input Pre Microphone Amplifier circuitHow it worksBalance Input Pre Microphone Amplifier as Figure 1.

The input signal will be sent to pin 3 and pin 5 of ICs, to increase signal. And send to pin 9-10 of IC3 that act as the differential amplifier. Thus, noise signal and various hum will be rid go away.The output from IC3 will be increased again with IC4 to get the output signal as need.The second section, the unbalance input as Figure 2 will see that the simple circuits by have two low noise ICs to connected together as the amplifiers circuit from microphone to high amplitude as need.Figure 2 Unbalance Input low noise pre microphone amplifiersHow to builds. You Just assembling equipment to the PCB correctly.As Figure 3 and Figure 4Figure 3 The PCB layout and components layouts of Balance Input Pre Microphone Amplifier circuitFigure 4 The PCB layout and components layouts of Unbalance Input Pre Microphone Amplifier circuitShould be used high-quality devices.
