Great product, works perfectly.

Used the GC-CGX to connect the emitter output from an IRTrans Ethernet module to my Speakercraft AT-1.0 connection block. Since the Speakercraft IR Receiver plug is 4 pin instead of 3, I connected the three wires on the GC-CGX directly to the wiring - on the GC-CGX cablenot the side with the plastic converter box sleeve=+12v, ring=-Ground, Tip=IR-Signal. Works great. I previously was feeding the IR light output from the IRTrans into a Speakercraft IR receiver which was not optimal.
