Hint for R21 to R24
Modify the resistances marked RF
and RA to increase the input sen-
sitivity (more amplification).
The formula is:
amplification = (RF/RA) + 1
E.g. to double the amplification because
the input of the connecting device is too
weak, mount 100K for RF (R22 and
R23).

Hint for R2 and R4:
To weaken the input (divide)
E.g. to connect the input with an amplifi-
er output.
Choose an inferior value for R2 and
R4.
The dividing factor = (R1/R2) + 1
E.g. a value of 100Ω for RD (R2 and R4)
will divide the input by 11.
