I'd like to know how to make the FX works. I plug in the mic but the FX does not work. tx
Hello Edson, welcome to the community.
The Xenyx 1002 does not have built-in effects. You could use an external effects processor connected from the FX SEND output and returned to one of the stereo channels (3/4, 5/6, 7/8 or 9/10). Turn the FX control on the return channel right down to avoid feedback.
There is a different model 1002FX that does have a built-in effects processor. To use it you turn-up the FX control on the channels you want to send to it and turn-up the FX TO MAIN control to adjust the level of effect in the main output.
