200 Watts True RMS Mono Amplifier Board with Inbuilt Speaker Protection

Image
This is an audio amplifier board, which can give an output of 200 Watts RMS at 4 ohms, and it can be used in any project of active subwoofer, Active Towers, Line Array Projects.   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 detecting dc at output terminals of amplifier, so speakers would be safe. By mistake if you short speaker wires, it would go off. We have designed it based on star ground designing method, so there is no humming, and noise based on design. Amplifier gives clean output.

LM3886 Special Edition Amplifier Board Building And Testing 🔊 IndianXtremeAudio

Image
  In this project we made an amplifier using Hi-fi and popular LM3886 Gainclone Amplifier IC. Many of us wants to make Virtual 5.1 or 7.1 Music System with this ic, but due to a lot of wiring we made a design with expandable feature, This Circuit has inbuilt Zobel Network, ABOUT THE PERFORMANCE The LM3886 is a high performance audio power amplifier capable of delivering 68W of continuous average power to a 4 Ohms load and 38W into 8 Ohms Load with 0.1% THD+N from 20Hz - 20Khz. The performance of the LM3886, utilizing its self peak instandaneous TEMPRATURE ( SPIKE ) Protection Circuitry, Puts It in a class Above Discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area. SPIKE Protection means that these parts are completely Safegaurded at the output against OVERVOLTAGE, UNDERVOLTAGE, OVERLOADS, Including shorts to the supplies, thermal runaway, and instantenous temprature peaks, The LM3886 Maintains an excellent signal to noise ratio of gr...
