Mixing Boards AUX Sends and Returns / Main Outputs / Other
AUX Returns provide a way to adjust signals being “returned” to the Mixing Board from outboard gear (such as a reverb or delay). The AUX Send controls how much signal is “sent” to the outboard gear (from the mixing board), and the AUX Return controls how much signal is “returned” back to the Mixing Board to complete the process. Besides using outboard effects and processors, the AUX Returns can also be used as extra inputs to your Mixing Board. You can hook up line-level devices such as CD Players, Digital Playback units, iPhones / iPads, etc.
