How to connect a mixer to a mixer to get more available channel inputs

[Guest]

I want to connect a simple mixer to another mixer to get more channels to connect xlr microphones...(I have the Behringer PMP2000)

Connect the outputs of one of the mixers into one of the inputs of the other.
If you need more information, we need more details (the model of the second mixer).
