you turn it one way the meter will read more voltage and as you turn it the other way you
will see the voltage decrease.
We recommend setting the bias to .065Vdc. The factory bias point is .065Vdc with 120Vac
on the mains line (wall voltage).
NOTE: The bias pot can be inadvertently turned if you
are reaching up into the back of the cabinet. If you think you may have turned the bias pot
by mistake simply follow the above directions to rebias the Impala.
If you are uncomfortable with the above instructions please see a qualified electronics
tech for bias adjustments.
