CONNECTING THE ARRAYS
Connect the BMA CT units to the CP2 unit via P-Link connections using
CAT6-24AWG solid conductor RJ45 cables.
The arrays must be powered by an external PoE source that supports
Mode B type power delivery. (A PoE Network Switch generally will not
work for this.) A PoE injector can either be connected to P-Link PoE port
on the rack-mounted CP2 unit, or it can be connected directly to the ar-
ray’s PoE In port.
When driving 2x10W speakers, each array requires its own PoE injector.
When the PoE injector is connected to the CP2 unit’s P-Link PoE port, the
CP2 unit’s P-Link Out port will provide both power and data communica-
tions to the array. If the PoE injector is connected directly to the array PoE
In port, a second cable must be connected from the CP2 unit’s P-Link
Out port to the array P-Link In port. (Note that the CP2 unit itself does not
provide PoE power without an external PoE injector.)
