Olin Lathrop k 30 Potentiometers R5 and R6 serves as the volume control for the left and right channels. I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors?

In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. Home Questions Tags Users Unanswered.
Hi Rahul use a 22k stereo control ganged control.
Your email address will not be published. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. What do You mean by “base output is poor”?

Leave a Reply Cancel reply Your email address will not be published. C11 and C12 are input DC decoupling capacitors for the left and right channels. Dataxheet is the function of capacitor and resistor at pin 4 and 7. Hi Soumen you can use the following datashee a very simple one with sigle control operating both the channels.
C1 and C5 are bootstrap capacitors for the left and right channels. Try uF, or even 10,uF.
C9 and C10 are noise filtering capacitors. I don’t have satasheet idea how to do that properly. Previous post Next post. Sign up or log in Sign up using Google. This makes the Bba5406 suitable for low power car audio applications. It will reduce the upper frequencies. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. Hi, what kind of a heatsink does BA need?
Thanks for your response.
Other applications of BA are portable audio players, stereo component systems, television etc. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply.
BA stereo amplifier circuit admin November 3, 11 Comments. Addng a low pass filter won’t improve anything. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.
Post as a guest Datasheey. So I’m planning to add extra low pass filter circuit to this circuit. Probably means ‘bass’ output is poor.

Can anyone tell how to use single pot volume control for both channels?? Is going to be back often to check up on new posts. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.
The problem here is the uF coupling capacitors into a 4 ohm load:
