Let me start the Audio Project with the basic of the BASICS of DIY Audio Amplifier Build.
Audio Processing – analog & digital
Hybrid Projects
DR100W Concept – a class D PWM 100W power amplifier based on the TDA8920BTH with hybrid Equalizer & Tone Control.
SAMuC 8051 – Smart Amplifier Manage using the 8051 Micro Controller and the C1237HA speaker protector IC used in diy amplifier build that protect your speakers from dangerous offset voltage.
AMPduino
AMPduino-A3CS – a shield for the popular Arduino Uno for monitor, detect and control DIY amplifier build.
