| The directional microphone published in the July-August 2002 issue of Elektor Electronics does its job, but does not have the right directio...
| Here is a very simple, inexpensive and interesting project which provides lot of fun to a home experimenter or hobbyist. This simple transmi...
| Commercially-produced subsonic microphones are too expensive for the cost-conscious user. However, as long as a high-precision measuring dev...
| In this semiconductor age, we find valves being used increasingly often for hi-fi and guitar amplifiers, top-end condenser microphones and s...
| Compared to the other instruments in a band the mouth organ is often not loud enough. Turn up the amplifier, and you risk feedback. What is...
| The signal from a microphone is two weak for a standard line input. This low-noise DC-coupled microphone amplifier provides a solution for a...
| Most soundcards have a ‘line’ input and one for an electret (condenser) microphone. To be able to connect an inductive tape-recorder head...
| The preamplifier is intended for use with dynamic (moving coil – MC) microphones with an impedance up to 200 Ω and balanced terminals. I...
| To many hi-fi enthusiasts and musicians, the thermionic valve (electron tube), the sound of a valve amplifier cannot be bettered by that...
