In most cases, we love to set the bass and treble setting to maximum when listening to music. This gives us a nice sound with bass and treble turned up. Here’s a simple circuit than can be placed at the input of your amplifier to boost the bass and treble. Keep in mind that this circuit is passive, meaning you can’t really boost signal using a passives circuit.

6 Channel Mixer with bass treble and echo controls
This is by far the most complex project that I have posted on my blog. I always wanted to build my own audio mixer but due to limited time I was not able to build anything like this.

Stereo Tone Control using transistor
Last time I posted about a tone control project using tone control here: simple-tone-control-design/
But that project is only a mono one and you must build 2 to have an stereo channel. So I made a simple PCB design for those who want to build the stereo version. For more information please click on the link above. It is basically the same.
The PCB design is made using Eagle PCB as usual and using a single layer PCB

MXR Distortion+ project
This is my very first project when I was in college simply because it is simple and the parts are readily available. It can be easily built using breadboard or universal PCB because it only requires few components. It uses a very popular op-amp 741.
Audio signal clipping/peak detector
If you want to have an indicator for your amplifier that tells you that the signal is clipping then this is the one for you. This circuit can be used at the input or output of the amplifier. You just need to change some resistor values to make it work.
Simple Guitar Distortion Circuit
Ever wonder how many components is the least you need to build a simple distortion effect for your guitar? The simplest I can think of will need 8 components. This is so simple that you can build the circuit even without using a PCB.
12W amplifier with TDA2008 IC
This is a very simple amplifier that can be used for your room sound system, kitchen or even for home theaters satellite speaker. It only requires few components at a very small board. It can operate at 12V supply. It can be able to deliver up to 12W at 4 ohms and 22V supply.
60-100W amplifier project
I have been wanting to build an amplifier like this but I have no time to build it so I thought I can just share this design and let you readers build it. The design is pretty much similar to Elliott’s Amplifier design with very minor tweaks. As usual I always simulate my design with simetrix to validate that my circuit is working correctly.
Speaker Protection Circuit
If you are an audio enthusiast like me who loves to build your
own sound system, this circuit is a must. This will protect
your expensive speaker from burning in case your DIY amplifier
breaks.
Arduino Controlled Bass Treble Volume and input Selector
Last time I have posted about how to control the LC75341 IC using arduino nano. And I also posted about how to modify the bass response of the LC75341 IC. This time I will be building a home amplifier for my TV, it will also feature a bluetooth reciever so that I can play via my phone.
