You can add as many Y-adapters as needed to the K3 AUX connector. In some of my setups, I have as many as four, due to the number of devices connected to the AUX signals. Just be sure you get Y-adapters that have all 15 pins wired through and none shorted to each other. Ed W0YK Robby, VY2SS, wrote: > What if I already have the AUX split for the KRC2?
