4. Enter the decimal value for the left side reference gain (RG
LS
) and the decimal value for the
desired gain (G) into the formula below:
For our example, the calculation would be:
X
LS
= 6.02
5. Calculate the gain setting for the left side by using formula A or formula B below:
Since our calculated X
LS
is less than 10.0, we would use formula A:
Left Side Gain Setting = 442.65
Round up to 443
