Silence audio o/p
In audio circuits, the control circit invariably produces some sort of hum. No matter what you do, getting silence at the
output is very difficult.
What are the different ways to obtain silent o/p? I autoroute my boards having control and power sections on the same board
using Layout Plus.
I am using amps in bdg configuration in the final stage. Instead of bridging it in the amp circuit itself, I plan to invert
the final control signal and feed the complementary signals to two identical amps.
I hope that this will eliminate the common mode hum. I also hope that this will eliminate the need to have a turn- on delay
circuit along with the bulky relay.
All comments and views welcome.
