The GPIO Expander expands the GPIO capability of a CONVERGE Pro 2 mixer by providing an additional 12 input and 12 output pins. This device gives integrators flexible connections to program LED activations on the microphones, trigger third-party devices; and trigger presets based on room configuration, such as combine/divide. The GPIO expander can be daisy-chained with other P-Link peripheral devices such as the Beam forming  Mic Array 2, DIALOG 20 Receiver, and USB Expander. It can also be used as a P-Link distance extender.
