I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. The operating voltage range is from 5 to 15V DC.

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. Hi Rahul use a 22k stereo control ganged control. The problem here is the uF coupling capacitors into a 4 ohm load: I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors?

Datzsheet this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency.

C1 and C5 are bootstrap capacitors for the left and right channels. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. I don’t have any idea how to do that properly. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier. Your email address will not be published.

What do You mean by “base output is poor”? Probably means ‘bass’ output is poor.

I make it well. Sign up or log in Sign up using Google. Olin Lathrop k 30 My requirement is to have separate left and right channels and an extra woofer out. Previous post Next post.

However, without knowing anything about the chip, it is obvious that really low bass performance will be poor. What do you mean by ‘poor’?

Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. Addng a low pass filter won’t improve anything. That’s no way to improve the perceived bass response.
