The LF353 of, National Semiconductor, is going to split audio signal into three bands. SANYO’S LA47536 is going to amplify these signals. In stereo mode, we shall have the action of eight high speakers who are going to create a very important sound pressure. Wide Bandwidth Dual JFET Input Operational 150 What Car Power Amplifier […]

Preamps Microphone Mixer circuit Choosing a good power amplifier is very easy but to choose the perfect microphone preamps is not easy, because the adjustment of sound pressure level (SPL) with volt level (dBu). Matching microphones and preamplifiers requires proper research and measurement, so to do this does not depend on your budget – but […]
