I have assembled 2 pcb as per circuit diagram but same problem in 2 pcb one channel it's fine and one channel it's not ok. How to possibly it's same problem it's circuit design not good

Very good quality product

Updating the review after a few days of usage. Upgrading from 1 start to 3 stars for the product. As treble potentiometer was bad.. I changed it and its working quite fine now. Ji I have used this product and I observed it okay product. Slight noise their. That's why giving 3 stars. And it cost me more to figure out the board problem and I need to buy extra potentiometer as the product was not well tested before sending. Board description : ---------------------- This board has 3 ic but 2 ic are for left and right channel gain setting. And one ic is for the bass setting. For the treble section, I don't see any ic. Conclusion:- You can buy this for bass control and for left and right channel gain setting. But for the treble section's its okay. You can buy this board. Note:- always solder the potentiometer before using this product and also set the gain to a minimum initially otherwise, you can fry your speaker. I had done this mistake. Overall okay product

Power full tone control. Very nice PCB and best stereo effects
