4. Enter the decimal value for the left side reference gain (RG
desired gain (G) into the formula below:
X = 20 log
LS
For our example, the calculation would be:
5. Calculate the gain setting for the left side by using formula A or formula B below:
Formula A
Left Side Gain Setting
Formula B
Left Side Gain Setting
Since our calculated X
Left Side Gain Setting
Left Side Gain Setting = 442.65
Round up to 443
