Operational Amplifier Used as SRS Effect Processor： R will be subtracted from L by IC1 to get a L-R signal. It will be sent into IC4 to be band-pass filtered to output f (L-R) signal after it is buffered and gain adjusted by IC2. IC3 will add the signal inversely to get -n(L+R), in which n is the gain in this stage regulated by 10k potentiometer. IC5 and IC6 are two full adder circuits, which are used to mix all kinds of signals. The output signal of IC5 is R+n(L+R)+f(L-R),which will be sent to track R to be amplified, and that of IC6 is L+n(L+R)+f(L-R),which will be sent to track L to be amplified. Extensity and contrast ratio will be regulated by potentiometer which will be connected externally by IC2 and IC3 respectively.
