Question

what do you propoze for radio mic on air wich procesor 

Answer 1

Not quite sure what you mean, but my best guess would be which external sound card would be best for a radio mic input? If that's what you mean, then as you only need a minimum number of inputs, then something like the Presonus AudioBox 96 would be fine. More details here:
