50 Watt apmplifier with TDA1514A Here is circuit audio amplifiers for car, which use it only number Transistor Circuit of IC, simple Circuit (and Top Popula) Use TDA1514A transistor at low cost. It best Idea Circuit. It’s receive a handful of additional external device in comparison to the generic diagram. Remember that there’s a simple HF filter on input signal. [...]
This circuit is a stereo amplifier for a high sensitivity stereo parabolic microphone that able to used for listening to distant sounds. Typical parabolic microphones are monophonic, this unit has a stereo audio path that helps produce more realistic sounding audio. The Big-E can be used with headphones or as an audio source for a [...]
Introduction: Amplifier device that accepts a varying input signal and produces an output signal that varies in the same way as the input but has larger amplitude. The input signal may be a current, a voltage, a mechanical motion, or any other signal; the output signal is usually of the same nature. The most common [...]
Every electronics engineer is familiar with the anxiety of the moment when power is first applied to a newly-built circuit, wondering whether hours of work are about to be destroyed in a puff of smoke. A high quality power supply with an adjustable current limit function is an excellent aid to steadying the nerves. Unfortunately [...]
With the astonishingly rapid growth in the market for flat-screen TVs and high-definition TV, many CRT television sets have been consigned to the attic, even though many of them were still working perfectly and could have been used as spare sets in a bedroom or another room, for example. Although all current flat-screen receivers have [...]
Here’s the simple design allows ATV to be transmitted from a low-power (up to about 3W) FM or CW transmitter. Ideally the transmitter should use CW mode and have its ‘key’ down but an FM rig will work just as well if the microphone is disconnected and the PTT switch is closed. The only reason [...]
Circuit Description There are many instances where a simple and reliable power amplifier is needed – rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own ‘Gainclone’ amplifier, this will certainly do the job This project (unlike most of the [...]
