The configuration of the speaker lines is selectable between Class A,,
Class B, or 2 x Class B.
Class A: The speaker line is looped back to the system. The end of line
resistor (EOL) is connected directly at the ZAM-180 (CC-5/-2). In this
configuration the line works during an open circuit condition by feeding it
from both sides. In the short circuit condition, the speaker line is not
functional.
