What do You mean by “base output is poor”? That’s no way to improve the perceived bass response. Your email address will not be published.
Can anyone tell how to use single pot volume control for both channels??
So I’m planning to add extra low pass filter circuit to this circuit. I tried to search for SIP package heatsinks, but nothing good came up. This makes the IC suitable for low power car audio applications. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. The operating voltage range is from 5 to 15V DC. Previous post Next post.

The problem here is the uF coupling capacitors into a 4 ohm load: Hi, what kind of a heatsink does BA need? Probably means ‘bass’ output is poor. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Sign up or log in Sign up using Google. Hi Rahul use a 22k stereo control b5a406 control. I don’t have any idea how to do that properly.

However, without knowing anything about the chip, it is obvious that really low bass performance will be poor. Ranath CS 1 2. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.
What is the function of datashedt and resistor at pin 4 and 7.
Post as a guest Name. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier. In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency.
BA stereo amplifier circuit admin November 3, 11 Comments. C1 and C5 are bootstrap capacitors for the left and right channels. Sign up using Email and Password. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply.
Do you mean that the lower frequencies are not loud enough? The Datasheett has great channel separation, good channel isolation, small pop-up noise, low noise, low thermal resistance and is available in a 12 pin SIP package. Sign up using Facebook. Potentiometers R5 and R6 serves as the volume control for the left and right channels. Addng a low pass filter won’t improve anything.

C11 and C12 are input DC decoupling capacitors for the left and right channels. My requirement is to have separate left and right channels and an extra woofer out. Hi Soumen you can use the following circuit a very simple one with sigle control operating both the 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? What do you mean by ‘poor’? Other applications of BA are portable audio players, stereo component systems, television etc.
