Each PCMZPM module has three relay driver outputs - RD A, RD B, and RD C - one for each speaker zone.
When a zone is activated, its relay driver is shorted to RD COM through an open collector transistor.These drivers can be used to activate
external relays to provide greater power capacity or to operate external equipment.The power supply for these relays must be 12V DC or
less.The total sink current per driver can not exceed 100mA.
