@@Audioguruji देखिए सर मेरा कहने का मतलब यह है आप इस वीडियो को देखें यही मैं आपसे बनवाना चाहता हूं क्योंकि आपके रिकॉर्डिंग बनाया हुआ सर्किट मेरे आराम से समझ में आ जाता है link pr dekhe ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J3frhLgmqBI.html
Will see that, don't worry, There are Many kinds of improvements in the amplifier but people like you don't see that, just comes here to tell us our mistakes, thanks a lot,
Very good build, congratulations, an amp with transformer soft start and speakker protection rare in this field . a small request transformer voltage 12-0-12 for pre amplifier may be upgraded to 15-0-15 for good headroom for 12 volt regulator ic. 12 ac measily adequate . awaiting more builds.
Very nice and clean design. 400 watts rated at what ohms? (4,6 or 8)? The only thing I didn't like was the face plate. Looks like cheap Delhi set. If you want to sell, please get machined, oil dampened panel or something which looks decent. Avoid unnecessary lights. Major change - passive cooling without fans, move that stupid usb into a hidden panel. Avoid colume lights and provide more juice to the amp. Some suggestions that is all. I can give you more but......thanks
@@GurnamSinghchannel in parallel, total impedance would be 3+ ohms and in series you will get 4+6 10 ohms, So you can not connect it with this amplifier as amplifier is designed for minimal impedance of 4 ohms and maximum of 8 ohms
volume 100K lga hua hai, aur Amplifier ka Gain, Bass Control se adjust hoga, Bass agar bahut kam hai aur volume full bhi hai to output kam ayegi, Bluetooth card ka gain bhi jyada nhi hota, accha output Auxiliary input se milega or mixer se milega
@@indianxtremeaudio everyone understand it, I was built sound boxes with TS parameters and design proper crossover with SB audience speakers, but in the end I checked, i observed power is enough but sound quality is very poor after this, I replaced your NE5532 bass travel board with Puja Plus bass treble board, with subwoofer filter, after this I found amazing sound because SB audience produce natural and accurate sound. You need to try to work on BT board like sound king... Every one can give power if they used original BJT 5200+1943, I observe no one working on preamplifier section BT board, every one trying copy and copy on BJT Power board.
