MC3−2To is a high−performance two−port HDBaseT card which is part of the compatible modular matrices multi−signal cards family. MC3−2To can flexibly occupy any of the matrix card slots and its output signals are independently switched by the modular matrix to any of the matrix input ports. MC3−2To Ethernet port, dual RS−232 and dual IR ports enable control signal extension from the connected HDBT receivers, in addition to the card dual analog audio ports which enable, independently per port, audio de−embedding or embedding.
