Hi Apex,
Just to elaborate more on the understanding i have Ahuja amp with 4 input unbalance mic/line and it has common bass and treble control, It makes difficult when there is to control male and female voice. So how can i make ML3 a 6 channel mixer (having advantage of 3 tone controls) and i will feed one output from my mixer to ahuja amp.

My ML3 Build has been running fine. I am impressed with its sound quality and stereo imaging.

Recently, a slight hissing sound appeared on one channel ( left channel ) after some 3 months.
This is prominent when there is no signal.
I tried changing the 100P but no luck.

Both the channels are in unbalanced mode. ( Line- and Ground).
Input source : Computer sound card.
The other channel ( right) is working really fine.
Any solution please?



Eagerly awaiting your feedback,
Som.

check with the cd player or phone if still the problem persist than may be your cable or pot track may be open

Weekend Project Part 2

Part 1 is AX-6 as you can find here.
ML3 should be the preamp. Project is a amplifier to use for the kids for karaoke and just for fun.
I made a new PCB to use components from the shelf.

Bass selector frequency and boost circuit

Hi all.
I want to build tone control to boost low bass frequency.
So my circuit must have two pot control.
Fisrt pot to select bass frequency example 20hz to 160hz
2nd pot to boost selected frequency.

Need help reference circuit and if can calculation for each part.
Thanks all.
