| The crossover network is intended for use when an existing audio installation is to be extended by the addition of a subwoofer. Often, t...
| A small audio test generator is very useful for quickly tracing a signal through an audio unit. Its main purpose is speed rather than re...
| The current drain of the regulator is minute compared with that of, say, a 78L05: at an input voltage of 9 V and open-circuit output, it...
| The present reference is a special application of current source IC Type LM334. It has a tiny temperature coefficient and draws only a m...
| The preamplifier is intended for use with dynamic (moving coil – MC) microphones with an impedance up to 200 Ω and balanced terminals. I...
| A pan pot enables a monophonic input signal to be positioned where desired between the stereo loudspeakers. When P1 (see diagram) is in...
| The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all fou...
