Daisy Chaining Effects Processors with a Mixer
How do I daisy chain multiple effects processors into one send/return loop on a mixer board?
Depending on what you're trying to achieve, your compressor is best utilized connected to an Insert point instead of the Aux Send. Connect the Aux send to the first effect's unit input, the first effect's unit output to the second effect's unit input and so on. Then connect the output of the last effect's unit to the Aux Return of the mixer.
