The bridge adapter circuit using NE5534 low noise IC to convert normal stereo to high power mono amplifier about 4 times,watt power lost approximately 75%
Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
This is 60W RMS OTL integrated audio amplifier circuit using 2N3055 and normal transistor so cheap and can build easily and It's durable and very loud sound [...]
The integrated amplifier that is smaller. For listening in a small room. Must have good the sound quality. Low noise and cheap.
This is Super stereo pre tone control project using LF353 low noise op-amp, easy to builds with PCB can adjust bass treble and volume on one PCB board.
An acoustic guitar pickup circuit that cheap and you can build with yourself. Suitable for the show enjoy of the party at home or in a group of friends.
We like Door buzzer sound circuit, in two-tone. It uses a low voltage power supply so it is safer. It saves if use battery. See the advantages, do not wait!
A simple fiber optic intercom communication systems to home use. Video Door Phone Intercom is going to happen in the future. or Meetings monitor route.
