200 Watts mono amplifier Board
Sharma Oct 19,2021
This is an Mono audio amplifier board, with a maximum output of 200 Watts RMS at 4 ohms + - 56VDC. This Amplifier can be used in any music system, like active subwoofer, portable line arrays, Active towers, Public address sytems. We have made inbuit rectified supply in the board, so no one needs to use bridge rectifier outside of the board. For protecting speaker in case of amplifier failure, we have used DC detected speaker protection module, which has a relay. it will disconnect speakers when ...

Bi-amplifier LM3886 For DIY Active Studio Monitor Speaker
barita Jul 25,2021
This is my DIY try to build bi-amplifier system using LM3886 gainclone IC for the final amplifier stage.I design this project with simple components that easy found on market.The way this amplifier working is when mono signal (Balanced / Unbalance ) give to the TRS input or XLR input, the signal will be divided by two way active cross over system with cross over point at 2KHz. The signal separated by two way : -Low freq processed by lowpass filter and will be amplified by LM3886 final stage ampl...

Speaker protection DEF 2021 | Защита АС DEF 2021
Urb May 07,2021
Все файлы для проектаУстройство предназначено для защиты акустической системы (предотвращения повреждения акустической системы), подключенной к усилителю мощности звуковой частоты в случае возникновения аварийной ситуации (в случае появления постоянного напряжения на выходе усилителя мощности). Кроме того, данная схема обеспечивает задержку подключения акустической системы к усилителя для устранения слышимых переходных процессов (хлопков динамиков и других неприятных звуков) при включении усилит...

EQD - Speaker Cranker
to Ukraine Apr 02,2021
The Speaker Cranker is an all discrete dirt enhancement device designed to give your signal some grit and a slight boost without drastically changing the character of your tone. It’s perfect for those that don’t like to fiddle with pesky controls yet want to add a little tube-like breakup or enhance an already over driven amp (or pedal) to give it some extra crunch without over loading the preamp. The single “More” control allows you choose the amount of break up you desire. Just like you would ...

Harry Potter bluetooth speaker - switches
ATomIng Nov 06,2020
This project was a Christmas present for my girlfriend, who loves Harry Potter. I decided to create a Bluetooth speaker with the Harry Potter design. I found some inspiration from Google Images for design. Because of lack of time I decided to buy a small Bluetooth speaker and just rebuild it.This DIY Bluetooth speaker is based on Bluetooth speaker CREATIVE MUVO 2c.Complete tutorial can be found on https://atoming.eu/harry-potter-bluetooth-speaker/ .3D parts for print can be found on https://www....
