Probably means ‘bass’ output is poor. BA stereo amplifier circuit admin November 3, 11 Comments. Thanks for your response.

Email Required, but never shown. Potentiometers R5 and R6 serves as the volume control for the left and right channels. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. Can anyone tell how to use single pot volume control for both channels??

In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. Sign up using Email and Password. This makes the IC suitable for low power car audio applications. That’s no way to improve the perceived bass response. Do you mean that the lower frequencies are not loud enough?

Hi, what kind of a heatsink does BA need?

Try uF, or even 10,uF. Your email address will not be published. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Post as a guest Name. I tried to search for SIP package heatsinks, but nothing good came up. Other applications of BA are portable audio players, stereo component systems, television etc.

Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier. What do You datassheet by “base output is poor”? Olin Lathrop k 30 It will reduce the upper frequencies. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency.

What is the function of capacitor and resistor at pin 4 and 7. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply.

However, without knowing anything about the chip, it is obvious that really low bass performance will be poor. So I’m planning to add extra low pass filter circuit to this circuit.

The BA 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. Is going to be back often to check up on new posts. Hi Rahul use a 22k stereo control ganged control. I make it va5406. Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.

C11 and C12 are datashete DC decoupling capacitors for the left ddatasheet right channels.

I just could not depart your web site prior to suggesting that I really enjoyed the standard info adtasheet person provide for your visitors? Addng a low pass filter won’t improve anything.
