I love this feature in the Behringer x32. The ability to link channels. This is particularly useful when you have a left and right channel of a stereo mix from a computer, or other listening device hooked up to the Behringer x32. With the press of a few buttons, you can link two channels that are next to each other, meaning each channel defaults to the other channel. So if I change the gain, eq, dynamics, volume... on one channel, the same settings are now on the linked channel, even the mutes.
