13W x 4 Audio Amplifier with Surround Sounds


This is my new audio power amplifier which is based on TDA8511 power amplifier IC. According to the datasheet this IC produces 13W per channel (with 2R load) and single TDA8511 chip contain 4 inputs and outputs.

Other than TDA8511 this amplifier use TA8184 for tone controls and LA2610 for surround sound processing.

To obtain the high sound quality and good separation I use separate amplifier module for each tweeter and woofer in both left and right channels. (That’s why I’m select TDA8511 for this project)

For the test run I couple this amplifier with my JVC DVD Player and it produces extreme high quality audio output.

Front Panel controls available in this amplifier are,

  • Volume
  • Bass
  • Treble
  • Balance
  • Surround Sound On/Off
  • Loudness Switch
  • Power On/Off

Some of the calculated technical specifications are,

  • Output Power : 13W x 4
  • Supply Voltage : 15V Single Rail
  • Total Harmonic Distortion : 1%
  • Bass Control Range : -12.5dB to +12.5dB
  • Treble Control Range : -12.5dB to +12.5dB
